Procédés de fabricationIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Process validation for cosmetic products is a requirement under GMP so that manufacturers can prove control of critical aspects of their operations. Cosmetic formulators always need to work closely with process and manufacturing engineers during the formulation development and scale-up stages in order to be able to put in place suitable and realistic methods for manufacturing cosmetic products. Formulating a product at lab scale so that it can be produced on a large scale is a complex process. Most issues that come to light during the scale-up process are usually due to inaccuracies found in the processing method, therefore it is important that the processing method put in place to manufacture a product produces consistent results so that the product retains its quality during its lifespan.

ParfumsIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Fragrance is one of the most important aspects of personal care products, providing a huge degree of sensory input and in many cases creating the clearest point of differenciation between one product and its competitors. But as with many other areas of the industry, fragrances have been affected by the "free-from" trend, creating additional hurdles for formulators. However, there are also plenty of opportunities to use innovative, multifunctional ingredients that offer natural scent without issues of sensitisation. Formulating with fragrances can be problematic, and that is why there are several ingredients here to help make the task easier. Other issues include being able to mask the unwanted odours of other ingredients used as part of the formulation. This is just a small sample of the ingredients out there to help you formulate with fragrances. Personal Care will be keeping a close eye on the Fragrance Zone at in-cosmetics this year in Barcelona, and will report back in June issue. Note de contenu : - Perfume-free fragrance

OlfactométrieIndex. décimale : 668.5 Parfums et cosmétiques Résumé : The human sens of smell has been underestimated for a long time. However, recent research shows that it is closely connected to emotions, memories, approach and avoidance, and also evaluative judgment. Therefore, the scent of a product can have a significant impact on consumers' product experience, its liking, the evaluative judgment of the products' qualities, and the products' purchase intention. Because of this, more and more companies are focusing on reducing, neutralising or masking unpleasant scents from their products or developing products with reducing or neutralising functions. In order to measure odour performance ( odour reduction, longevity of fragrances, etc. ), reliable and repeatable olfactory measurements should be carried out. The result can help R&D to optimise the product, support quality control and can also be used by marketing for example as claim support. The following article summarises the key elements and possibilities of odour measurements. Note de contenu : - Odour measurement

LimnanthesLa limnanthe est un genre de plantes herbacées annuelles communément appelées meadowfoam. Les sept espèces sont originaires des régions côtières et adjacentes (vallées intérieures, contreforts et les montagnes) de l'ouest de l'Amérique du Nord , où elles poussent généralement dans des habitats marécageux, tels que les marges des mares printanières. Certaines sont endémiques à la Californie.
ProductionIndex. décimale : 668.5 Parfums et cosmétiques Résumé : On-farm activities are the highest contributor to global warming when thoroughly examining the complete meadowfoam seed oil supply chain. Natural Plant Products has chosen no-till farming, including shrewd use of herbicides and pesticides, in an effort to reduce petroleum usage, one of the highest environmental cost inputs of farming. Futhermore, hexane extraction is a more efficient process for capturing oil from the seeds of meadowfoam. For this reason, Natural Plant Products uses hexane in its manufacture of meadowfoam seed oil for the personal care industry. This study has shown that increasing manufacturing efficiency decreases the amount of diesel fuel burned. Given the fact that over 80% of meadowfoam seed oil's GWP comes from on-farm activities, reducing acreage necessarily reduces negative environmental outcomes occuring from farming of any crop that is grown. Is hexane extraction the "greener" option when looking at a transparent supply chain ? It is distinctly possible. Note de contenu : - BRIEF HISTORY OF VEGETABLE OILS IN COSMETICS

Produits de la merIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Sustainability is a major concem within the cosmetics and toiletries industry. Consequently, the development of alternatives with effective naturel ingredients is an important challenge for raw materials manufacturers.
Aquatic environments, including oceans, lakes, rivers, hot springs, and lagoons, offer an incredible richness of biodiversity and many opportunities to develop new naturel bioactive compounds that respond to the requirements of sustainable cosmetics.
In the marine environment, algae are one of the largest groups in terms of diversity, and according to Guiry, they have been estimated to have from 30,000 to more than 1 million species.' Classically, the algae also named as 'seaweeds', are divided into three major groups (green, brown and red) largely based on the colours of the pigments they synthesise. In fact, an extensive range of pigments including phycobiliproteins is present in algae. They are highly fluorescent proteins classified into two large groups based on their colours, the phycoelythrin (red), and the phycocyanin (blue). Interestingly, algae developed adaptive responses to environmental stress (UV, pH, high temperature, bacteria, pressure, turbulence...) and thus, under optimised conditions; they are able to produce more or fewer pigments or other active molecules.
Greentech, through its subsidiary Greensea specialised in phycotechnology, take advantage of the adaptive responses in algae for the production of a large and diverse array of biochemical constituents. Thus, we developed several actives from marine origin and with various activities. For example, the first marine active contributes to vascular tonicity enhancement (to correct rosacea). It corresponds to a subtle mix between oligosaccharides and essentiel oligoelements, obtained by metabolic induction of the microalga Porphyridium cruentum.
The second active is extracted from the red algae Hafymenia durvillaea. It is an anti-ageing care active that extends the cellular life cycle and delays the cellular senescence. In the present review, an attempt has been made to throw light on the discovery of two marine active ingredients from microalgae and macroalgae developed by Greensea/ Greentech.Note de contenu : - MARINE PHYTOCHEMICAL COMPOUNDS WITH COSMETICAL APPLICATIONS

UltrasonsIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Ultrasound is a well-used method for particle size reduction in dispersions and emulsions across many industries and applications. While the use of ultrasound in the processing of personal care formulations does happen, it is currently not very commun. In fact when asking 25 manufacturing clients and colleagues across the European personal care industry, only two were currently using sonication (one of which was just finalising installation of new equipment for the first time). Traditionally, personal care formulators have tended to use high shear homogenisation techniques to form emulsions and dispersions.
After researching the possibilities with ultrasound, it became clear it not only offers alternative processing methodology but also opens the door to potentially novel formulations. This is particularly in efficient processing of emulsions and indeed the creation of highly stable emulsions with incredibly low surfactant content.
The aim of this article is to briefly explore sonication as an interesting and potentially exciting processing option for personal care formulations, particularly emulsions.Note de contenu : - Ultrasound and emulsions

LaminairesLa Laminaire (Laminaria) est un genre d'algues brunes de la famille des Laminariaceae. Son thalle en forme de ruban peut mesurer jusqu'Ã 4 m de long.
Certaines laminaires sont récoltées de manière artisanale ou industrielle. Elles étaient utilisées au même titre que le (goémon) comme engrais, puis dans l'industrie agroalimentaire pour leurs polysaccharides ; les alginates qui sont des gélifiants alimentaires. Reconnaissable par les codes E400 à E405, les alginates forment des gels thermostables (qui ne se liquéfient pas à la chaleur) qui permettent la tenue, la reconstruction des aliments (jambon, poisson pané).
Peau -- Soins et hygièneIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Skin is a large and complex tissue where the orchestral actions of resident cells are necessary to support its structural and metabolic integrity. Cells of the epidermis ( mainly keratinocytes ) play a role in protecting from environmental stress such as UV exposure, mechanical damage and pro-oxidative attacks. Perhaps more importantly, top layers of the epidermis along with a lipid-rich intercellular matrix from the skin barrier. It is no secret that the skin barrier is fundamental in preventing excessive water evaporation thereby supporting normal skin hydratation levels. A functional barrier also prevents penetration of allergens that sometimes can exacerbate sensitive skin conditions. With age, the rate of epidermal cell renewal and the ability of the skin barrier to repair from a physical insult decrease. Ageing not only weakens epidermal structures and functions but also deregulates the metabolic activity of fibroblasts. Indeed, some metabolic pathways are increased and others are decreased in aged skin fibroblasts. The best example is the general reduction in collagen synthesis and the augmentation in the production of matrix metalloproteases (MMPs) causing a gradual dismantling of the extracellular matrix (ECM) organisation. We tested a laminaria extract ( commercial name : Regenesea-LS, INCI Name : Glycerin (and) Water (and) Laminaria saccharina extract ) for its effects on epîdermal molecular pathways using cDNA experiments on human skin equivalents. We also verified the ability of the laminaria extract in rejuvenating aged skin fibroblasts at the gene expression level. The actions of the extract were confirmed clinically by measuring various parameters including skin barrier function, hydratation, skin smoothness, wrinkle density and volume as well as visco-elastic properties.

Fucoïdanesfamille de polymères hétéropolydispersés à base de fucose et d'autres oses ou acides uroniques.
Un fucoïdane, ou une fucoïdine, est un fucane complexe qui appartient à la famille des polymères hétéropolydispersés à base de fucose et d'autres oses ou acides uroniques. Les polymères hétéropolydispersés sont des macromolécules dont les fractions peuvent toujours être séparées en sous-fractions et ainsi de suite jusqu'à aboutir théoriquement à la séparation des molécules.
Malgré cette diversité en taille, de composition et de structure de chacune des molécules, les fractions obtenues avec une méthode donnée ont pourtant des propriétés physico-chimiques toujours parfaitement reproductibles.
Les fucoïdanes tirent leur nom des algues du type fucus, et ils sont souvent assimilés comme des polysaccharides présents dans le wakamé ou d'autres algues brunes de mer. Des formes variantes de fucoïdane ont également été trouvées chez des espèces animales, notamment chez les concombres de mer.
Le fucoïdane est (parfois...) employé en complément alimentaire pour améliorer les échanges cellulaires et leur vitesse d'activité, avec une amélioration du système immunitaire.

PolyphénolsLes polyphénols constituent une famille de molécules organiques largement présente dans le règne végétal. Ils sont caractérisés, comme l’indique le nom, par la présence d'au moins deux groupes phénoliques associés en structures plus ou moins complexes, généralement de haut poids moléculaire. Ces composés sont les produits du métabolisme secondaire des plantes.
Les polyphénols prennent une importance croissante, notamment grâce à leurs effets bénéfiques sur la santé. En effet, leur rôle d’antioxydants naturels suscite de plus en plus d'intérêt pour la prévention et le traitement du cancer, des maladies inflammatoires, cardiovasculaires et neurodégénératives. Ils sont également utilisés comme additifs pour les industries agroalimentaire, pharmaceutique et cosmétique
"Ils ont tous en commun la présence d'un ou plusieurs cycles benzéniques portant une ou plusieurs fonctions hydroxyles". La désignation "polyphénols" est consacrée par l'usage et, alors qu'elle ne devrait concerner que les molécules portant plusieurs fonctions hydroxyle phénolique, elle est habituellement utilisée pour l'ensemble de ces composés.
Les polyphénols naturels regroupent donc un vaste ensemble de substances chimiques comprenant au moins un noyau aromatique, portant un ou plusieurs groupes hydroxyle, en plus d’autres constituants. Il y a quatre principales familles de composés phénoliques : les acides phénoliques (catéchol, acide gallique, acide protocatéchique), les flavones, l'acide chlorogénique et les quinones. Ils peuvent aller de molécules simples, comme les acides phénoliques, à des composés hautement polymérisés, de plus de trente mille daltons, comme les tanins (acide tannique).
Les polyphénols sont communément subdivisés en phénols simples, acides phénoliques et coumarines, en naphtoquinones, en stilbénoïdes (deux cycles en C6 liés par deux atomes de carbone), en flavonoïdes, isoflavonoïdes et anthocyanes, et en formes polymérisées : lignanes, lignines, tanins condensés. Ces squelettes carbonés de base sont issus du métabolisme secondaire des plantes, élaborés par la voie du shikimate.
Les polyphénols sont présents dans diverses substances naturelles : sous forme d'anthocyanine dans les fruits rouges, le vin rouge (en relation avec les tanins, phénomène du "paradoxe français"), sous forme de proanthocyanidines dans le chocolat et le vin, d'acides caféoylquinique et féruloylquinique dans le café, de flavonoïdes dans les agrumes, et sous forme de catéchines comme le gallate d'épigallocatéchine dans le thé vert, de quercétine dans les pommes, les oignons, le vin rouge, etc.
D'après une étude réalisée avec des volontaires via Internet, les sources alimentaires de polyphénols sont principalement le café (36,9 %), le thé — vert ou noir — (33,6 %), le chocolat pour son cacao (10,4 %), le vin rouge (7,2 %) et les fruits (6,7 %)18. Parmi les fruits, les polyphénols, très présents dans toutes les pommes, sont encore plus concentrés dans les pommes à cidre (riches en tanin), qui peuvent en contenir jusqu'à quatre fois plus : c'est une biodiversité qui se manifeste en richesse aussi bien qualitativement que quantitativement en polyphénols. (Wikipedia)
PolysaccharidesLes polysaccharides (parfois appelés glycanes, polyosides, polyholosides ou glucides complexes) sont des polymères constitués de plusieurs oses liés entre eux par des liaisons osidiques.
Les polyosides les plus répandus du règne végétal sont la cellulose et l’amidon, tous deux polymères du glucose.
De nombreux exopolysaccharides (métabolites excrétés par des microbes, champignons, vers (mucus) du ver de terre) jouent un rôle majeur - à échelle moléculaire - dans la formation, qualité et conservation des sols, de l'humus, des agrégats formant les sols et de divers composés "argile-exopolysaccharide" et composites "organo-minéraux"(ex : xanthane, dextrane, le rhamsane, succinoglycanes...).
De nombreux polyosides sont utilisés comme des additifs alimentaires sous forme de fibre (inuline) ou de gomme naturelle.
Ce sont des polymères formés d'un certain nombre d'oses (ou monosaccharides) ayant pour formule générale : -[Cx(H2O)y)]n- (où y est généralement x - 1). On distingue deux catégories de polysaccharides : Les homopolysaccharides (ou homoglycanes) constitués du même monosaccharide : fructanes, glucanes, galactanes, mannanes ; les hétéropolysaccharides (ou hétéroglycanes) formés de différents monosaccharides : hémicelluloses.
Les constituants participant à la construction des polysaccharides peuvent être très divers : hexoses, pentoses, anhydrohexoses, éthers d'oses et esters sulfuriques.
Selon l'architecture de leur chaîne, les polysaccharides peuvent être : linéaires : cellulose ; ramifiés : gomme arabique, amylopectine, dextrane, hémicellulose et mixtes : amidon.

Taches pigmentaires (dermatologie)Index. décimale : 668.5 Parfums et cosmétiques Résumé : Marinova, an Australian biotechnology company, developed two speciality cosmetic ingredients from marine algae. Maritech Bright is a Fucus vesiculosus derived extract ( pictured ) comprising both fucoidan and polyphloroglucinol, and Maritech Reverse is a high purity fucoidan from Undaria pinnatifida. Fucoidan is a sulphated, fucose rich polysaccharide with multiple bioactivites. Polyphloroglucinols are unique marine algal derived polyphenols with profound antioxidant activity. In clinical trials, the protective and soothing activity of 0.3% w/v preparations of each of the Maritech products was assessed. Both products were clinically proven to be highly effective at protection and soothing as measured by erythema and transepithelial water loss after solar simulation. Maritech Reverse was assessed for elasticity and wrinkle depth in older Caucasian women, and demonstrated an increase in elasticity and decrease in wrinkle depth, roughness and redness.

VanillineIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Preservation has always been under the spot light; even more so is preservation of naturel products.
Traditional substances that have been long used to preserve cosmetic products are undergoing radical reviews by the competent Authorities, which could potentially lead (or already have led) to drastic reductions of the allowed concentration in formula.
This, in conjunction with a growing consumer demand for more natural products, can inspire formulators to 'borrow' ingredients from allied industries.Note de contenu : - Fig. 1 : Chemical structures

Iodopropynyl butylcarbamateconservateurs autorisés en cosmétique, établie par la réglementation européenne.Index. décimale : 668.5 Parfums et cosmétiques Résumé : Preservation is a vital part of any personal care formulation. We require preservatives to protect our products from the effects of bacterial, yeast and fungal growth. Selecting the correct system to perform this task is not a simple process — many factors will need to be considered before the correct choice can be made. The system must not only be robust enough to ensure that a finished product is sterile when first made, but also that it minimises risk of contamination right up to the expiry date.
In this paper, we will discuss the challenges faced by cosmetics chemists when evaluating preservation options. Regulatory pressures, consumer perception and the abundance of new and conflicting studies of varying degrees of scientific credibility make preservation selection increasingly complex. We will discuss recent trends, some of which are promising, while others, such as non-preservative alternatives, may actually pose greater risk. We will also explore the advantages of IPBC (iodopropynyl butylcarbamate) as a preservative, whether used as the sole active or as part of broad-spectrum blends, some of which offer unique benefits in the marketplace.Note de contenu : - Personal care preservation background

Tests microbiologiquesIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Each cosmetic product marketed requires a challenge test (CT), regulated by the European Regulation 1223/2009. According to this regulation, CT is not required for two categories: low microbiological risk products (e.g. product with alcohol above 20%, products with organic solvents, high/low-pH product), and single use or no air contact products.'
Standard ISO 2962: 2010 sets limits of pH (below 3 or above 10), ethanol (above 20%) and (below 0.75), that defines a product as low risk of microbial contamination and such that does not require the application of microbiological International Standards for cosmetics.
Challenge test is an effective solution to evaluate contamination risks, and avoid bacteria, mold, or yeast proliferation. However, CT is expensive and laborious. Without an effective preservative system, proliferation of microorganisms can cause health hazards, skin infections, pH changes and degradations (odour, colour, general appearance) .
Many publications have studied parameters which influence CT. In the food industry, an article in 2008 by Bekada AMA et al., studied water activity, pH and temperature on the growth rate of mucor racemosus isolated from soft camembert cheese. In the cosmetic industry, a work conducted by Rahali Y et a1., studied the optimisation of on the preservation of cosmetics and impact on the use of the challenge test', published in 2013.
Following this work, the aims of this present study are to determine when the CT could be avoided and to reine limits obtained in the previous work.Note de contenu : - MATERIALS AND METHODS : Raw materials - Formulation - Analysis - Definition of the constraints and th efactors tested - Experimental design - French standard AFNOR NF T75-611 (antimicrobial preservative efficacy test) and ISO 11930 ; 2012

Peau -- Soins et hygièneIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Each cell has to anabolise and catabolise active ingredients every day, communicating with and replying to an extemal and internal environment, continually evolving. To be involved in these activities, the tells modify the composition of their membranes by an elaborate system capable to add or remove the proteins embedded into this protective envelope, such as receptors, ionic channels, and the transporters. By the mechanism of the cellular exocytosis, all the synthesised or imported ingredients arrive to their final destination : the cellular membrane or the extracellular space. By the inverted mechanism of endocytosis, the tells may import into their interior space all the components of the cellular membrane to be utilised or catabolised. Alternatively, they may capture many nutrients, such as vitamins, lipids, amino acids, etc, transporting them into the cytosol where they are used for the different biosynthetic processes. These main biological activities of all the organs, such as the skin, maintain the human body in equilibrium.
The main objective of cosmetic dermatology is, therefore, the development of new active ingredients, able to maintain the skin homeostasis and slow down its ageing process. The use of ingredients and means, capable to mimic the regular activity of ECM, modulating the skin reparative systems by the regular synthesis of collagen and elastic fibres, is, therefore, among the main goals of the dermatological and cosmetic companies.
Chitin nanofibril is a promising ingredient that, bonded with other natural polymers to form nanoparticles or nanofibres, seems to represent an innovative bioactive ingredient capable to modulate the skin cell's daily life, protecting its bio-structure from the environmental aggressions. Moreover, the possibility CN has to act in accarding with the NICE-TCM approach, is a further reason to increase the studies on this fascinating natural polymer, for better understanding its real, mechanism of action. This is the future challenge of our research group.Note de contenu : - Proteins and cell information

AutophagieL’autophagie, autolyse ou autophagocytose, désigne une dégradation d'une partie du cytoplasme de la cellule par ses propres lysosomes. L'histolyse est le même processus, mais intervenant lors d'une métamorphose, il est utile à l'organisme (par exemple, les amphibiens). L'histolyse est également présente au cours du développement embryonnaire ou en fin de lactation.
Le terme d'autophagie regroupe plusieurs voies de dégradation lysosomale des constituants cellulaires, essentielles à l’homéostasie cellulaire. Il existe trois types différents d’autophagies dont : la microautophagie, l’autophagie réalisée par des protéines chaperonnes, et la macroautophagie (la forme principale). La macroautophagie, appelée couramment autophagie, est un mécanisme permettant à la cellule de digérer une partie de son contenu, que ce soit du cytoplasme, des protéines ou des organites cellulaires. C’est la seule voie qui puisse dégrader massivement des macromolécules et des organites, c’est une voie de dégradation alternative à celle du protéasome.

People demand to remain young, with better looks as they age, such as smaller pores, fewer wrinkles, and less sagging, and to moderate skin disorders, such as irritation, dryness, redness, dandruff etc. The former target is mainly known as anti-ageing. The main target is to remodel and rescue our skin from intrinsic and extrinsic damage. People want to keep their youth or even to turn back time in order to look younger. This market is strongy growing. So, numerous anti-ageing ingredients have been developed to focus on the reactivation or boosting of cutaneous tells' proliferation and/or skin component secretion, such as extracellular matrix-like collagen, hyaluronic acid. But on the other hand, the latter focuses are less limited to skin normalisation and/or moderation from disorder. For those targets, the focus is on skin homeostasis to naturally keep its correct levels. This skin mechanism works in normal skin but weakens due to intrinsic bio-stress, chronological ageing or immunity imbalances, and/or extrinsic stress, chemicals and sunlight (UVs/IRs).
In this study, we examined the effects of an innovative biomimetic peptide, which was developed from naturel moisturising factor (NMF), for regulating biological mechanisms involved in skin homeostasis, by measuring a cellular detoxification response to extrinsic oxidative stress and an efficacy on cellular maintenance system of redox, chaperone and autophagy. At the same time, we performed a preliminary clinical trial for hydration effcacy of this moisture peptide, to assess the physical effect of the peptide, not only biological efficacy.
Our results pointed out this new NMF derived biomimetic peptide can show not only physical moisturising efficacy like the original skin, NMF, rather than well-known the moisturising compound hyaluronic acid, also bas biological efficacy to induce a self-maintenance property compared to the well-known antioxidant, ascorbic acid. These efficacies are confirmed by cDNA microarray, qPCR and protein expression. Interestingly, we found this peptide could promote autophagy in a similar way to potential anti-ageing medicine, rapamycin. In conclusion, this study provides potential efficacies of this NMF-derived moisture peptide as a 'skin care vaccine' which induces the self-protection mechanism to maintain the healthy condition of skin, and moreover we can expect anti-ageing efficacy though cutaneous stem tell maintenance by autophagy.Note de contenu : - METHODS : Clinical moisturising test - Intracellular ROS scavenging activity - cDNA microarray - Western blot analysis - Puncta formation assay

While the applications have been traditionally limiter due to the inherent properties of finely milled oats producing colloidal oatmeal, a recent innovative extrusion process has resulted in a new ingredient by Oat Cosmetics called Oat COM, providing additional functionality for the cosmetic formulator.
Extruded colloidal oatmeal not only delivers enhanced skin moisturisation by providing excellent hydration and emolliency benefits, but the formulator no longer has to worry about the settling out of this ingredient like most traditional colloidal oatmeals. The resulting extruded colloidal oatmeal provides superior skin-feel and enhanced soothing properties. The shelf-life of this new ingredient is greatly enhanced compared to current ingredients on die market. In short, Oat Cosmetics' extruded colloidal oatmeal Oat COM, provides a relatively inexpensive means to provide and deliver a wider range of oat phytochemicals known to provide 'significant. benefits to our skin and should be an ingredient on any formulator's shelf.Note de contenu : - Oat phytochemicals

Mélanges (chimie)Index. décimale : 668.5 Parfums et cosmétiques Résumé : We take most products for granted in the sense that they are contained in sonne kind of appropriate packaging ready to be used where and when that packaging is opened. We simply dispense or remove it from that packaging and then use it as one would expect — simple, uncomplicated and requires little, if any, thought. However, not ail products can be simply stored within prinnary and secondary packaging for long periods of time and under normal daily conditions and then removed and used 'as is'. Take vaccines, for exempte — the refrigeration cold chain is vital to the integrity and efficacy of the formulation that is needed at the location and time of use as the complex proteins of viral vaccines can be easily denatured by raised temperatures. This is a classic case of unstable substances needing special treatment to maintain their efficacy.
This instability applies across many sectors, not least the personal care industry. Many actives, at least many of the ones with recognised efficacy, cannot be formulated into standard formulations, stored for extended periods ready for use and then deliver the efficacy the consumer experts. Formulating and packaging unstable personal care products such that the efficacy of the active(s) within those products is maintained or created at the time of use can take one of several forms ; many of which have been borrowed from parallel industries.Note de contenu : - Mixing components at the time of use
