Sensibilité cutanéeIndex. décimale : 668.5 Parfums et cosmétiques Résumé : More than 70% of consumers say that they use cosmetic products to improve their quality of life. 80% use cosmetics to improve self-esteem. 68% think that their use of cosmetics is important of how they are perceived by others. It is clear what consumers expect from the cosmetic industry. They want us to develop products which fit these primary needs. 86% of consumers expect tangible effects. This means that they want their cosmetic products to work for them.
Apart from the above, the consumer is increasingly health-minded. 'Health is the new wealth'. Consumers are aware of the link between appearance, lifestyle factors and health. This goes for skin health as well. Compared to the past, consumers have a more pro-active attitude towards care of their skin. They find skin health much more important than trying to erase wrinkles or age spots. They understand that maintaining healthy skin will help in maintaining young looking skin. Skin protection is a key factor for them. On top of that, healthy skin is considered to be attractive skin. Healthy skin looks good and feels good. Healthy skin is in balance. Healthy skin is strongly associated with overall wellbeing. Inversely, when skin is not healthy, overall wellbeing is strongly impaired.
The number of people suffering from skin diseases is growing tremendously. The incidence of atopic dermatitis has doubled over the last 3 decades. A significant percentage of the population suffers from psoriasis. Acne is a common problem, especially for adolescents, but adult acne is a growing phenomenon as well. Also systemic diseases, like diabetes type 2, a vastly growing problem, can have strong implications for skin. Itch is a common problem for many consumers. In addition to the increased prevalence of skin-related diseases, the average consumer has a negative perception about her or his skin. When asked to describe their skin, in virtually all cases people describe it as problematic, e.g. dry, oily, sensitive etc.
In the light of the above, it is unsurprising to see strong growth in 'dermocosmetic brands' and so-called 'Dr¬brands'. Consumers trust these brands to provide them with cosmetic products which fit their needs, to solve their problems and to improve their health, wellbeing and quality of life. They have high expectations, though. Betraying their trust will lead to them not continuing to buy the product. It is therefore of utmost importance that the product fulfils their needs. Key words are: skin health and wellbeing.Note de contenu : - Skin health and wellbeing ?

CaroténoidesLes caroténoïdes sont des pigments plutôt orange et jaune répandus chez de très nombreux organismes vivants. Liposolubles, ils sont en général facilement assimilables par les organismes. Ils appartiennent à la famille chimiques des terpénoïdes, formés à partir de la polymérisation d'unités isoprènes à structure aliphatique ou alicyclique. Il est généralement admis qu'ils suivent des voies métaboliques similaires à celles des lipides. Ils sont synthétisés par toutes les algues, toutes les plantes vertes et par de nombreux champignons et bactéries (dont les cyanobactéries).

PhotoprotectionIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Blue light-induced skin damage originates from two sources: natural blue light, which is part of sunlight, and artificial blue light, which cornes from electronic devices. Topical applications that protect from blue light have reached the cosmetic market. But efficient blue light absorbers are rare.
Nature's answer to blue light are carotenoids, which shield blue light and protect against blue-light induced oxidative stress in plants. Lipoid Kosmetik's active ingredient Carotolino is designed to supply carotenoids to the skin, where they can naturally act as a defensive shield against blue light and reduce oxidative stress. Besides its photo¬protective activity, topically applied carotenoids improve skin colour. Indeed, our in vivo study demonstrates that Carotolino creates a subtle color optimization, shifting pale and dull skin tones to a more lively and healthy appearance.
Carotolino incorporates the best of carrots including stabilised carotenoids. This makes our botanical active a trendy ingredient that synergistically reduces blue light¬induced skin damage while at the same time adding a vivid look.Note de contenu : - Carotenoids - blue light absorbers invented by nature

Pâteux (ingrédients cosmétiques)Index. décimale : 668.5 Parfums et cosmétiques Résumé : Waxes are a crucial tool for formulators, modifying skin-feel while also assisting in waterproofing and improving resistance to rub-off. While waxes can be natural or synthetic, butters are obtained from the kernel, nut or seed of fruit such as shea, almond and mango. Butters melt on contact with the skin can deliver a luxurious feel as well as a soothing, moisturising effect.
Texture is one of the key points of differentiation in personal care and cosmetic products, so waxes and butters certainly have important roles to play here, along with the ability to deliver a high level of natural content to formulations.
Following is a selection of some of the latest wax and butter ingredients from leading global suppliers.Note de contenu : - Butter ingredients

Formulation (Génie chimique)
Pâteux (ingrédients cosmétiques)Index. décimale : 668.5 Parfums et cosmétiques Résumé : The story of aesthetic butters mirrors in many ways the evolution of cosmetic product development over the years. Our customers have always needed ingredients that work well in formulations. But they are also now looking for natural sourcing, functional benefits, and industry trend alignment. Butters are proving to be well-suited to these multiple objectives.
Hallstar's personal butters story began with its acquisition of Biochemica® in 2011. A premium, naturally-derived butter and oils pioneer, Biochemica had already established a broad portfolio of butters obtained through a patented cold extraction process and featuring citrus fruits, cocoa, aloe, avocado, pomegranate and other ingredients. The recognizable, popular ingredient sources of these products continue to support compelling natural product daims and provide consumers with pleasing natural scents and multifunctional, healing properties :
Butters' ingredient-specific characteristics enable companies to meet two distinct market demands. Beauty consumers will always desire the core properties butters bring to personal care but they are also searching for goods tailored specifically to their evolving lifestyles. To develop products that cater to this second, less tangible desire, companies need to get inside the minds of consumers and understand what they will want from their personal care products today, tomorrow and beyond.
Hallstar is committed to incorporating its trends research into a next-generation of all-natural butters that can also address the sourcing and functionality preferences consumers have corne to expect. Our investment in developing new Biochemica products— like 2018's Turmeric Butter and our latest CBD Hemp Butter - is based in our belief that butter-based products will continue to deliver the right stuff for our customers.Note de contenu : - Formulary benefits

Pâteux (ingrédients cosmétiques)Index. décimale : 668.5 Parfums et cosmétiques Résumé : Floraesters 15, 20, 30, 60, and 70 [INCI: Jojoba Esters] are derived from jojoba oil (Simmondsia chinensis), and are widely used in a variety of finished product categories for skin care, hair care, and colour cosmetic applications. Due to their composition and occlusivity, each of the Floraesters provides multiple benefits to personal care and cosmetic formulations, including skin hydration' and barrier repair and protection. Floraesters also enhance product shelf life due to their superior oxidative stability.
Unlike some jojoba butter ingredients, jojoba esters are interesterified, not partially-hydrogenated or a mixture of the oil and wax. Interesterification produces only cis-unsaturated esters and no trans-fats. Because jojoba is a wax ester and not a triglyceride oil, jojoba esters are 'oil-free' emollients. Ranging from liquid to soft paste to solid (see Table 1), Floraesters can be utilised within emulsion systems to provide body and skin care benefits, and within anhydrous formulas like lipsticks to achieve the desired hardness, payout, and shine/matte finish.Note de contenu : - Oxidatively stable jojoba-derive butters and waxes

The skin barrier function is continuously exposed to aggressions. The daily use of soaps and potentially aggressive detergents can alter the hydrolipidic skin film and skin barrier integrity, reducing its impermeabilising action and favouring skin dehydration. Trans Epidermal Water Loss (TEWL) constitutes one of the main indicator to evaluate skin barrier integrity. The ideal detergent must be able to effectively remove dirt, greasiness and pollutants, meanwhile respecting the lipidic and protein fractions of the horny layer and the superficial hydrolipidic film.

Dentifrices -- Composition
ErythritolL’érythritol (ou tétrahydroxybutane, ou érythrite) est un polyol (ou sucre alcoolisé) découvert en 1874. C'est un édulcorant naturel que l'on trouve dans les fruits, les aliments fermentés ou la sauce au soja. Il possède un pouvoir sucrant inférieur au sucre (de 60-80 % à poids égal), mais présente deux avantages : il contient moins de calories que le sucre de table (0,2 kcal/g contre 4 pour le sucre), et ne cause pas de caries. Il peut être produit à partir du glucose en fermentant celui-ci avec des levures appropriées dans des solutions aqueuses.
- Structure : L'érythritol est un polyol qui ressemble au xylitol, mais avec un atome de carbone en moins. Il possède quatre fonctions alcool. Il est le composé méso (R, S) du butane-1,2,3,4-tétrol, diastéréoisomère du thréitol. C'est un composé de formule : CH2OH-CHOH-CHOH-CH2OH et sa masse molaire est de 122,1 g/mol.
- Propriétés physiques : L'érythritol est un corps polymorphe qui se présente sous une forme cristalline blanche qui fond à 121 °C. Il forme de gros prismes pyramidaux.
L'érythritol est très soluble dans l'eau (100 g·l-1 à 20 °C) mais moins que le saccharose. Les solutions aqueuses sont peu conductrices.
Comme il n'est pas hygroscopique (il n'attire pas l'humidité), il conduit, en cas de cuisson, à des produits qui ont tendance à se dessécher si un autre composé hygroscopique n'entre pas dans leur composition.
Lors de sa dissolution dans l'eau l'érythritol engendre une réaction endothermique. Le même effet se produit en bouche lors de la consommation de cristaux d'érythritol ce qui provoque une sensation de froid (frais).
Formulation (Génie chimique)Index. décimale : 668.5 Parfums et cosmétiques Résumé : Even 2000 years ago, the Romans understood the need to clean their teeth and used crushed ashes, soda and myrrh as their dentifricium. In the 19th century the addition of flavourings and abrasives such as marble powder and soap powder led to a more sophisticated formulation. The most simple polyol, glycerine, was added as a humectant and sweetener at the end of the century and the "toothpaste" went into industrial production. At the same time the cariogenic nature of oral bacteria was discovered, along with a scientific understanding of the damaging effect of the metabolism of sucrose and organic acids on the enamel.
Polyols are applied as a bulk sweetener in a large number of oral care products globally. Polyols cannot be metabolised by oral bacteria and the findings of some new studies suggest that erythritol in particular displays better functionalities than other polyols. The efficiency and properties of sugar alcohols are dictated by their chemical structure. They have some functions in common but their chemical profile determines the efficiency of specific anti¬caries properties. Sorbitol and xylitol are the main polyols used in toothpaste, mouthwash and dental chewing gums. In recent years, oral care products containing xylitol — and latterly erythritol — have increasingly been available on the global market. Even the EFSA (European Food Safety Authority) recognises that the use of polyols as a sugar replacement in food items contributes to the maintenance of tooth mineralisation (EU Commission Regulation 432/2012).Note de contenu : - Typical functional ingredients in toothpaste : Fluoride - Abrasives - Detergents - Polyols as humectants and sweeteners

Peau -- Soins et hygièneIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Skin brightening is one of the most demanding segments in the cosmetic industry. The global consumer demand driven by an ageing population and men's increasing interest in grooming defines new targets for skin brighteners. Human skin pigmentation is a complex and tightly regulated process. The main factor known for stimulating skin pigmentation is solar radiation. The main modulation of melanogenesis induced by UV in melanocytes is mediated by the production of cytokines and hormones or prostaglandins by keratinocytes, that stimulate not only the melanogenesis but also dendritogenesis, melanosome transfer and melanocyte proliferation. Visible light has been shown to activate metalloproteinases and to decrease collagen production by inducing oxidative stress. Blue light stimulates melanogenesis by acting directly on melanocytes to induce skin hyperpigmentation. In this context, it appears of pivotai importance to develop a new natural multi-faceted cosmetic active ingredient offering a wide broad-spectrum activity addressing the main signalling pathways involved in pigmentation and hyperpigmentation. Larix sibirica wood extract, rieh in bioflavonoids, is of relevant interest as an antioxidant for lightening applications. It prevents melanin biosynthesis and melanogenesis, and acts as DNA protector with dual anti-ageing activity. Siberian Larch extract represents a highly efficient natural, preservative-free, China compliant, safe, easy to formulate solution for skin lightening. This versatile multi-faceted cosmetic ingredient, marketed under the trade name Sibwhite®, offers a natural and powerful lightening solution, Cosmos approved and Natrue compliant with a very safe profile for radiance and rejuvenating skin.

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.

Taches pigmentaires (dermatologie)Index. décimale : 668.5 Parfums et cosmétiques Résumé : Fucoidans are unique fucose-rich polysaccharides naturally found in the cell walls of brown seaweed. They are highly bioactive compounds that play a pivotai role in protecting seaweed from water-borne pathogens and damage caused by ultraviolet light (UV). Extensive research has shown that fucoidan extracts can similarly impart protective effects on the skin and have diverse benefits in dermatological applications.
Fucoidans are highly branched, complex polysaccharides of varying size, typically with a high molecular weight. Fucoidans are characterised chemically using validated assays that quantify the sulfation, acetylation, molecular weight and the content of sugars in the carbohydrate 'backbone'.
Fucoidans differ in chemical structure and bioactivity depending upon the species of seaweed from which they are derived, and the method by which they are extracted. Australian biotechnology company, Marinova, specialises in the solvent-free extraction of organic fucoidan compounds from two fucoidan-rich species of brown seaweed; Undaria pinnatifida and Fucus vesiculosus.
The company's two high purity fucoidan skin care ingredients each have distinct benefits and bioactivities. Extracted from polyphenol-rich Fucus seaweed, Maritech Bright®, is a clinically validated brightening ingredient with powerful anti-oxidant properties. Proven to have protecting and soothing effects, Maritech® Reverse is extracted from undaria seaweed. Both ingredients have shown profound anti-ageing properties by inhibiting key enzymes responsible for skin damage and boosting proteins. The Maritech ingredient range is the only certified organic fucoidan extracts developed specifically for skin care applications.Note de contenu : - Enzyme inhibition

kératinesLa kératine est une protéine, synthétisée et utilisée par de nombreux êtres vivants comme élément de structure, et également l'exemple-type de protéine fibreuse.
La kératine est insoluble, et peut être retrouvée sur l'épiderme de certains animaux, notamment les mammifères, ce qui leur garantit une peau imperméable. Parfois, lors d'une friction trop importante, la kératine se développe à la surface de la peau formant une callosité. Les cellules qui produisent la kératine meurent et sont remplacées continuellement. Les morceaux de kératine qui restent emprisonnés dans les cheveux sont couramment appelés des pellicules.
La molécule de kératine est hélicoïdale et fibreuse, elle s'enroule autour d'autres molécules de kératine pour former des filaments intermédiaires. Ces protéines contiennent un haut taux d'acides aminés à base de soufre, principalement la cystéine, qui forment un pont disulfure entre les molécules, conférant sa rigidité à l'ensemble. La chevelure humaine est constituée à 14 % de cystéine.
Il y a deux principales formes de kératines : l'alpha-kératine, ou α-keratin, présente chez les mammifères notamment, dont l'humain, et la bêta-kératine, ou β-keratin, que l'on retrouve chez les reptiles et les oiseaux. Ces deux types de kératines ne présentent clairement pas d'homologie de séquence.
Chez l'être humain, la kératine est fabriquée par les kératinocytes, cellules se trouvant dans la couche profonde de l'épiderme. Les kératinocytes absorbent la mélanine (pigment fabriqué par les mélanocytes), se colorent et ainsi cette pigmentation de l'épiderme permet de protéger les kératinocytes des rayons ultraviolets du Soleil.

Produits capillairesIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Cosmetic anti-pollution products have a strong growing potential due to the increase of pollution ail around the world. According to the World Health Organization, 92% of the global population is affected by excessive air pollution. Following this worldwide concern, the cosmetic industry has launched a lot of skin care solutions against pollution but there are only a few products dedicated to hair care for this concern. However, the hair, as the skin, is the first thing exposed and impacted by pollution. Note de contenu : - Importance of the cuticle for hair health

Tests d'efficacitéIndex. décimale : 668.5 Parfums et cosmétiques Résumé : The diversity of life remains one of the most striking aspects of our blue planet. It is estimated that about 195,000 eukaryotes species are catalogued in oceans and more than 2,200,000 are predicted. These data include animalia, chromista, fungi, plantae and protozoa without any precise mention for microalgae and macroalgae.
Nowadays, algae are classified in four kingdoms: Cyanobacteria, plantae, chromista and protozoa. Among them, macroalgae constitutes an exceptional reservoir of innovative molecules for cosmetic purposes due to the important algal biodiversity throughout the world. They may bring numerous bioactive compounds incorporated in a wide range of products like creams, lotions and shampoos among others.Note de contenu : - MATERIALS AND METHODS : In vitro study - Ex vivo study and immunolabelling - In vivo study
