Sécurité des produits de consommationIndex. décimale : 668.5 Parfums et cosmétiques Résumé : When we taste a naturally-derived product such as coffee or olive oil, we may have a different sensorial experience based on the product’s origin and its processing. Malbec wine produced in Argentina may taste similar to Malbec wine produced in California but not identical. Olive oil from Greece does not have the same sensorial profile as that from Tuscany.
They are just different and, as consumers, we can choose the one that fits the experience we want. Those differences are linked to genetic and environmental components as well as processing practices. Similarly, naturallyderived cosmetic ingredients from the same plant can have different characteristics and chemical properties depending on the various geographical locations of the plant as well as the processing of the extract.
Those properties can eventually affect the safety and efficacy of the finished cosmetic product and also in this case the formulator can choose the one that is looking to fit its formulation design. It is important to know that not only colour and smell could be affected (a prerequisite for selection) but also chemical composition. Since a specific active or undesired substance can be in a higher or lower concentration depending on the plant’s origin and processing, the ingredient composition can affect the safety and efficacy of the finished product.Note de contenu : - The influence of plant geographical location - environment

Perhaps one of the most impactful recent changes in the personal care industry is the need for a sound strategy for the use of preservatives that considers regulations, consumer demand and cost-effectiveness for a more sustainable and eco-aware market.
Ever more effective preservatives must give way, creating a strong need for powerful alternatives. A challenge that holds opportunities. Contemporary strategies lean towards multifunctionals that are more costly but promise much more than preservatives. Molecules with multiple functions help formulators to achieve additional claims enabling lesser ingredients and pamper overall value for money.
This article concentrates on an innovative technology that enables formulators to implement a sound preservation strategy and to substantiate secondary claims based on consistent in-depth analysis.Note de contenu : - MULTIFUNCTIONALS : THE NEW NORMAL

Photovieillissement (dermatologie)Index. décimale : 668.5 Parfums et cosmétiques Résumé : Although it has been known for many years that peroxidation of lipids in skin is increased by sunlight and atmospheric pollution, and that the products contribute to the ageing of skin, sunburn, and skin cancers, relatively little attention has been given to the process. This has largely been owing to the absence of a technology to protect tissues from the products of lipid peroxidation.
However, this may be about to change thanks to a UK start-up created by two former Oxford medical scientists, one of whom was the co-discoverer of the protective effect of high-density lipoproteins (HDL, commonly known as 'good' cholesterol) against heart disease.
The founders knew from their academic cardiovascular research that one of th eprotein components of HDL particles is able to protect vascular cells from the toxic effects of lipid peroxides by sequestering them, and that peptides had been synthesized with even greater affinity for the molecules, even though they had no sequence homology to the HDL protein.
The idea of transferring the technology to skincare had been prompted when they discovered, when studying HDLs in tissue fluid collected from the skin of healthy volunteers, that the concentration of lipid peroxides in the fluid was many times greater than could be explained by the level in blood.Note de contenu : - What are lipid peroxides ?

Industrie cosmétique -- Aspect de l'environnement
Ingrédients cosmétiquesIndex. décimale : 668.5 Parfums et cosmétiques Résumé : The 'all-natural' trend continues to gain a lot of traction in the global cosmetics market. Ever more consumers demand quality with naturality but also sustainable cosmetic products.
In future, these high expectations could merge with new expectations of efficiency, opening the way to biotechnological, sustainable and ultra-efficient solutions that meet the expectations of consumers looking for more advanced solutions.
One of the key pillars of sustainability is the environmental aspect with respect and protection of the planet and with the critical goal of biodiversity preservation. In fact, the impact on biodiversity is the third most common information expected by consumers to be displayed on packaging.
This for good reasons. Biodiversity is a key indicator of the health of an ecosystem and it is declining fast, mainly due to human activity.
Biodiversity is not only an ecological and social responsibility topic but also a business necessity.
For ingredient suppliers, biodiversity should be taken into account in the ingredient design process, especially when it tomes to sourcing for the manufacture of natural ingredients.Note de contenu : - Limiting the impact on biodiversity

Ingrédients cosmétiquesIndex. décimale : 668.5 Parfums et cosmétiques Résumé : The efficacy of beauty and personal care (BPC) products remains at the forefront of consumers' minds, particularly as a majority of BPC consumers research ingredients and product effectiveness before they make a purchase. At the same time, there is a growing expectation that ingredients are natural and eco-friendly.
However, without achieving performance equal to or greater than synthetic materials, natural and biobased alternatives will not fully replace incumbent materials nor satisfy customer and consumer needs.
Polymers are an important class of ingredients and are included in the production of most high-performance BPC products. The value of polymer ingredients in the personal care market is forecast to grow at a compound annual growth rate of 3.8% between 2021 and 2026.1
They can be found in hair products, such as shampoos and conditioners, and in skincare products, such as moisturising lotions and liquid soaps. Each of these polymers have distinct functions and uses, as well as different characteristics in composition, manufacturing process, and physical and chemical parameters.
Polymers are typically used to impart various specific functions in formulations, serving as rheology modifiers, solubility enhancers, dispersing agents, butking agents, skin and hair conditioners, sunscreen agents, film-formers, aesthetic modifiers, and abrasives/exfoliants.Note de contenu : - A difficult trade-off

Hyaluronique, acideL'acide hyaluronique est un type de polysaccharide (plus précisément une glycosaminoglycane) non fixé à une protéine centrale et largement réparti parmi les tissus conjonctifs, épithéliaux et nerveux animaux.
Il se trouve notamment dans l'humeur vitrée et le liquide synovial. Il est l'un des principaux composants de la matrice extracellulaire ainsi que de certaines mucoprotéines lorsqu'il est associé à une fraction protéique.
Depuis les années 1990, il est très utilisé dans divers dispositifs médicaux, médicamenteux et cosmétiques (présenté dans ce dernier cas comme "antistatique, humectant, hydratant, conditionneur cutané, anti-âge, etc."), bénéficiant d'un effet de mode grandement soutenu par une large publicité commerciale.
Contribuant de façon significative à la prolifération et à la migration des cellules, l'acide hyaluronique est aussi impliqué dans la progression de certains cancers. (Wikipedia)

Peau -- Soins et hygièneIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Today's beauty consumer demands sustainable, animal-free, and performance driven products. These shifting sentiments put active ingredients in the spotlight and demand innovation. Biodesign is rising to the challenge. This approach to product development combines advances in computational biology and precision fermentation to deliver the best of nature's depth and diversity to consumers. White many are familiar with biotechnology's first breakthrough ingredient — hyaluronic acid (HA) — proteins like collagen have rapidly emerged as the pioneering products enabled by biodesign.
HA from microbial fermentation paved the way for future fermentation-derived bioactive ingredients. In 1998 scientists at Savient Pharmaceuticals successfully produced high molecular weight HA, historically sourced from rooster combs, through precision fermentation of the microorganism Streptococcus zooepidemicus' Biotechnology unlocked the potential to create sustainable alternatives to animal-derived molecules that eliminate unethical practices, complicated supply chains, and the use of environmentally harsh chemical processes.
Collagen is another popular ingredient in beauty and an important target for biodesign as it is the most abundant protein in the human body, responsible for structure, stability, and strength within the dermal layers. In addition to its essential structural function, collagen is a signaling molecule defining cellular activities.
There are at least 28 types of collagen identified in the body, all sharing a common triple helix structure yet differing in a- chain composition.Note de contenu : - ECM stimulation - in vitro

Concentration minimale inhibitrice (antimicrobiens)En microbiologie, la concentration minimale inhibitrice (CMI) est la plus faible concentration d'un produit chimique, généralement un médicament, qui empêche la croissance visible d'une ou de plusieurs bactéries. La CMI dépend du micro-organisme considéré, de l'être humain affecté (in vivo uniquement) et de l'antibiotique lui-même.
La CMI est déterminée en préparant des solutions du produit chimique in vitro à diverses concentrations croissantes, en incubant les solutions avec des groupes séparés de bactéries en culture et en mesurant les résultats en utilisant une méthode de dilution standardisée (agar ou microdilution). Les résultats se classent ensuite comme "sensible", "intermédiaire" ou "résistant" à un antimicrobien particulier en utilisant un point d'arrêt. Les points d'arrêt sont des valeurs convenues, publiées dans les directives d'un organisme de référence, comme le US Clinical and Laboratory Standards Institute (CLSI), la British Society for Antimicrobial Chemotherapy (BSAC) ou le Comité européen sur les tests de sensibilité aux antimicrobiens (EUCAST). On a pu constater des écarts importants au niveau des points d'arrêt de divers pays européens au fil des ans, et entre ceux de l'EUCAST et du CLSI.
Alors que la CMI est la concentration la plus faible d'un agent antibactérien nécessaire pour inhiber la croissance visible, la concentration bactéricide minimale (CBM) est la concentration minimale d'un agent antibactérien qui entraîne la mort bactérienne. Plus la CMI est proche de la CBM, plus le composé est bactéricide.
La première étape de la découverte d'un médicament est souvent le dépistage d'un médicament candidat de banque de données pour les CMI contre les bactéries d'intérêt. En tant que tels, les CMI sont généralement le point de départ pour de plus grandes évaluations précliniques de nouveaux agents antimicrobiens. Le but de la mesure de la concentration minimale inhibitrice est de s'assurer que les antibiotiques sont choisis efficacement pour augmenter le succès du traitement. (Wikipedia)

Triclosan -- Suppression ou remplacementIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Due to the pandemic and the increased need for consumers to stay and feel clean, the personal hygiene sector has experienced a real upswing in 2020. While the interim focus was mainly on hand hygiene, personal hygiene today has branched into a broad variety of applications ranging from scalp to toe including oral care. In this article, we present new results on a modern cosmetic ingredient for oral hygiene that answers the quest for safe environmentally friendly antimicrobial solutions.
For decades, triclosan has been a preferred ingredient in toothpaste and mouthwash thanks to its versatile hygiene benefits. In the last couple of years, the market has been gradually forced to move away from such conventional organohalogen technologies. This process has not only been accelerated by the US ban on triclosan from antibacterial soaps, the global overuse of ingredients Eike triclosan and triclocarban and their environmental impact triggered more and more Legal restrictions and consequently, cosmetic brands have phased these ingredients out of formulations to serve consumers with safer and more eco-friendly solutions.
SymGuard® CD, [INCI : phenylpropanol, o-cymen-5-ol, decytene glycol] - hereafter described as the cosmetic hygiene ingredient - is one of the modem options for personal hygiene with key benefits in oral care 5.6Note de contenu : - Antimicrobial activity relevant to oral hygiene

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.

Vagin -- Soins et hygièneIndex. décimale : 668.5 Parfums et cosmétiques Résumé : The skin is colonized by billions of bacteria that participate in the regulation of immunity and barrier functions, preserving the microbiota homeostasis are essential to maintain a healthy skin and mucosa.
The vaginal microbiota is composed of 90% lactic acid bacteria (lactobacilli) that colonize the vagina at puberty. This microbiota is critical to maintaining vaginal health. About 250 bacterial species have been identified in the human vagina. In healthy women of reproductive age, the vaginal microbiota is generally dominated by the genus Lactobacillus, with a prevalence of L. crispatus (59%), L. gasseri (16%), L. iners (22%), and L jensenii (3%) species. However, in most cases, only one species of lactobacilli is present.
These lactobacilli have very specific functions. They stimulate the local immune system and form biofilms that create real protective shields. They transform glycogen secreted by the genital mucosa cells into lactic acid, thus creating an acidic environnent necessary to maintain the vaginal pH between 3.5 and 4.5.
The vaginal pH reflects the vaginal microbiota's health: a pH higher than 4.5 indicates an imbalance in the vaginal flora, also called dysbiosis. Dysbiosis can be accompanied by symptoms such as unusual discharge, itching or vulvar pain and can sometimes lead to infection (mycosis, vaginosis etc.). During menopause, the pH is naturally 4.5.
Each woman hosts several types of lactobacilli which will evolve during her cycle and her life according to hormonal variations, her environment, her intimate hygiene, her sexual life, etc.
During menopause, there is a progressive decrease in estrogens, and therefore also in lactobacilli of the vaginal mucosa. It is estimated that between 55% to 70% of menopausal women suffer from vaginal dryness.
Furthermore, more than 30% of postmenopausal women and 16% of women in general, are suffering from dyspareunia (pain during sexual intercourse), an unrecognized and often hidden problem mostly due to a microbiota imbalance. Women speak more and more about their intimacy and want to limit their discomfort but very few products meet consumers' specific needs.Note de contenu : - Red kapok flower extract
