Quinoa et constitantsIndex. décimale : 668.5 Parfums et cosmétiques Résumé : NaturePep Quinoa is part of TRI-K Industries' natural peptide technology platform and addresses difficult to treat skin problems such as under eye bags, puffiness, eyelid sagginess, folds and creases. Due to a multi-targeted mechanism of action, this unique bioactive reduces under eye bags by stimulating adipocyte lipolysis. It also stimulates the production of extracellular matrix components to strenghten fragile skin around the eyes. The specific composition consisting of small natural peptide fragments ensures a broader range of biological activity and multiple skin benefits to de-puff, rejuvenate, lift and reshape the eye contour appearance. This versatile technology represents an effective natural anti-ageing solution for the cosmetic eye care category. Note de contenu : - CAUSES OF UNDER EYE BAGS AND EYELID WRINKLES

Économie circulaireL'économie circulaire est une expression générique désignant un concept économique qui s'inscrit dans le cadre du développement durable et s'inspirant notamment des notions d'économie verte, d’économie de l'usage ou de l'économie de la fonctionnalité, de l'économie de la performance et de l'écologie industrielle (laquelle veut que le déchet d'une industrie soit recyclé en matière première d'une autre industrie ou de la même).
Son objectif est de produire des biens et services tout en limitant fortement la consommation et le gaspillage des matières premières, et des sources d'énergies non renouvelables ;
Selon la fondation Ellen Mac Arthur (créée pour promouvoir l'économie circulaire1), il s'agit d'une économie industrielle qui est, à dessein ou par intention, réparatrice et dans laquelle les flux de matières sont de deux types bien séparés ; les nutriments biologiques, destinés à ré-entrer dans la biosphère en toute sécurité, et des intrants techniques ("technical nutrients"), conçus pour être recyclés en restant à haut niveau de qualité, sans entrer dans la biosphère

Peau -- Soins et hygièneIndex. décimale : 668.5 Parfums et cosmétiques Résumé : We rarely realize the true importance of water and its impact on every aspect of life on Earth. From the influence it had on being central to human civilization to its importance as probably one of most, if not the most, widely used chemical agent in industrial activities, to the fact that we are mainly made of water.
The vast majority of cosmetic products contain variable quantities of water, with an average oil-in-water emulsion ranging from 70% to 80% and certain formats such as micellar cleansers featuring it at even higher concentration.
Some rightly argue that there is better use to water with an alarmingly huge number of people having little, or no, access to fresh and clean water to satisfy their basic survival needs.
Recent cosmetic trends are going towards the use of fewer ingredients as well as water-less formulae; that is products that are formulated with less water and possibly with more functional water, e.g. plant or fruit water that also delivers skin benefits.
In addition, a major focus on sustainable and circular economy principles as a way to go beyond the mere concept of “natural” is pushing formulators of cosmetic products and producers of ingredients to seek alternative sources of water.Note de contenu : - A sustainable, by-product-derived alternative to water

Soins de beauté masculinsIndex. décimale : 668.5 Parfums et cosmétiques Résumé : It is said that we only have three seconds to make a positive first impression and we rarely have a second chance. Considering that the first thing we look at is the eyes of another person, it is no wonder that one of the principal aesthetic concerns is the eye contour. According to the American Society of Plastic Surgeons, eyelid rejuvenation is the fourth most popular type of plastic surgery, and the most requested among men. The natural active Eye'fective derived from two white flowers, Crataegus monogyna (Hawthorn) and Jasminum Sambac (Arabian jasmine) is a multifunctional active with "eye triangle care" effect. It has been successfully demonstrated that the active is able to decrease vascular permeability to avoid the accumulation of components that darken the skin tone. In addition, it improves blood flow, increases bilirubin degradation, reduces melanin content and thus has a lightening effect on dark circles. In vivo studies confirm the improvement of blood circulation in the eye contour and a reduction of dark circles with excellent results in just 14 days. In the same period, the active also has a lifting effect on the upper eyelid and flattens the wrinkles in the crow's-feet area. As a consequence, Eye'fective minimises the appearances of dark circles and under eye pigmentation, provides treatment against blotches and improves skin smoothness in the periorbital area for a denser and refreshed skin with a younger look.

Produits synthétiquesIndex. décimale : 668.5 Parfums et cosmétiques Résumé : As consumers favour natural essential oils over synthetic alternatives, the price of essential oil escalates, maily due to expensive production costs. The rising monetary value of plant oil tempts unscrupulus companies in the industry to produce and sell adulterated essential oils tainted with cheaper synthetic ingredients. The onus is on distributors and manufacturers downstream to identify these alduterated products before they reach the consumer market.
In many cases, it is difficult to distinguish between naturally derived ingredients and synthetic alternatives. Natural product testing through carbon-14 analysis authenticates plant-sourced ingredients while also acting as a screening tool to detect synthetic alduterants manufactured from petrochemicals.Note de contenu : - Rising demand for essential oils poses challenges for manufacturers and distributors

Taches pigmentaires (dermatologie)Index. décimale : 668.5 Parfums et cosmétiques Résumé : The quest for means to get a beautiful skin is endless. However, defining what is beautiful partially depends on the geographical and ethnic origins of the persons. For instance, having a white skin is an extremely important element of the women's beauty in Asian culture. The desire for white skin originally cornes from traditional Asian values and beliefs. This desire has also been reinforced by Western influences (for instance Caucasian models are often used in adverts for European or American cosmetic brands sold in Asian countries). That is the reason why whitening/lightening products are among the best-selling products in the Asian cosmetic industry and are also becoming very important in Middle East, Africa and South America. In these areas, for many people, hyperpigmentation and skin pigmentary spots are not only considered as aesthetic problems, but they are also synonymous of decreased self-esteem, premature skin ageing and may facilitate the occurrence of skin damages, exacerbated by sun exposure. Conversely, Caucasians are looking to tan their skin since many consider tanning as a marker of a healthy lifestyle. But recent global consumer surveys on the primary cosmetic concerns of women have identified uneven skin tone and age spots as major concerns relative to signs of ageing. Trying to maintain or to regain a uniform skin tone, clear of age spots, is therefore a major and shared objective to consumers worldwide. Note de contenu : - Clinical study

Titre : Effects of glycolic acid on human hair keratin Type de document : texte imprimé Auteurs : Christian Allan, Auteur ; Jeffrey Weeks, Auteur ; Florence Olechowski, Auteur ; Sabilla Digel, Auteur Année de publication : 2019 Article en page(s) : p. 67-71 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Acide glycolique L'acide glycolique (ou acide hydroxyacétique) est le plus petit des acides α-hydroxylés (AHA).
L'acide glycolique est obtenu à partir d'extrait de canne à sucre, de betterave ou de raisin.
Grâce à son excellente capacité à pénétrer la peau, l'acide glycolique est très utilisé dans les produits de soins pour la peau, le plus souvent dans les peelings.
Toxicité : L'acide glycolique peut être très irritant selon les niveaux de pH5. Il peut être irritant pour la peau, les yeux ou les voies respiratoires6. Comme l'éthylène glycol, il est métabolisé à l'acide oxalique, ce qui peut le rendre dangereux s'il est ingéré.

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. (Wikipedia)Index. décimale : 668.5 Parfums et cosmétiques Résumé : Glycolic acid is a well-known active ingredient in skin care products. The alpha-hydroxy acid exfoliates skin by reacting with the upper layer of the epidermis, the strateum corneum, and weakening the lipid bonds that hold the outer dead skin cells together. Subsequently, this allows the outer layers to be removed exposing healthier, living skin cells. This mechanism of action for glycolic acid in skin care has been extensively studied and documented.

Its spicy, musky smell had a reputation in the Middle Ages for warding off evil spells ! In the Renaissance, the root was recognised for its digestive properties, and the essential oil for its ability to induce sweating; it was also used against infections and epidemics such as the plague; while "angel grass" or its sister "angelica sinensis" is used in traditional Asian medicines. Edible, it is still used mixed with candied fruit in desserts (the French town of Niort is famous for its candied Angelica sticks), and in several famous liqueurs and luxury perfumes.

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.
DermatologieIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Autophagy is a cellular mechanism wich preserves cell health by recycling long-lived proteins and damaged organelles. With the discovery of its mechanism by Professor Yoshinori Ohsumi (Nobel Prize in Physiology and Medecine 2016), autophagy has been the subject of intense research interest that revealed its role in various physiological and pathological conditions.
This catabolic pathway consists of multiple sequential steps, promoted through two well-characterised signalling cascades known as mTOR (mammalian Target Of Rapamycin)-dependant and mTOR independant pathways. The process starts with the sequestration of the targeted organelles subject to degradation along with a portion of cystosol into a double-or multi-membrane stucture known as phagophore.
This structure elongates after closure to form a vesicular structure, termed autophagosome. Subsequently, the mature autophagosome fuses with the lysosome, thereby forming a single membrane structure (autolysosome) where protein degradation is promoted by lysosomal enzymes.
Autophagy constitutively occurs at basal cellular level to ensure the homeostatic turnover of cell components but can also be activated in the following conditions: (i) when the cells need to mobilise intracellular nutrients, (ii) when the cells need to clear potentially toxic cytoplasmic materials or (iii) when the cells are under various stress conditions like oxidative stress or radiation. Under these circumstances, altered components are degraded to be subsequently replaced by newly produced ones, allowing the cells and organisms to preserve their physiological functions.Note de contenu : - Autophagy, an essential process for our skin health

Ingrédients cosmétiquesIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Cosmetic products are often primarily judged by their sensorial properties, as these can be evaluated right away, even before purchase. These properties, which include appearance, texture and scent, are an essential aspect when differentiating products, regardless of active ingredients. Consumers also tend to subconsciously link certain textures to efficiency, for example denser formulations are often perceived as especially nurturing and skin smoothening, while fast absorbing products are assessed as particularly moisturising. Furthermore, today's consumers are highly experience driven, with 60% finding trying out new experiences more exciting than trying out new products. This pushes companies to explore unique textures, like transforming textures or ones not normally found in the product category, which can also serve to enhance perceptions of efficacy. The use of varying textures in skin care and make up product is particularly appealing to milennials given that they are most receptive to unique applications and formats such as gels, foams, and masks. Another benefit of an appealing sensorial profile is an increase in application frequency/quantity, resulting in higher product benefits and perceived efficacy. Besides being functional ingredients that can stabilise and regulate viscosity of formulations, waxes are also able to enhance sensory properties ans have a huge influence on texture of both anhydrous products and emulsions. This article will highlight the differences of five distinct natural waxes and their influence on texture and sensorial attributes of cosmetic formulations.

Produits nettoyantsIndex. décimale : 668.5 Parfums et cosmétiques Résumé : The texture of a cosmetic product is paramount, alongside fragrance and colour. You could even say that texture is more important than efficacy when it comes to the first point of sale; how a product feels on application could make or break a sale. So what exactly is texture and how can we quantify it ? From a technical point of view, texture is a function of viscosity and rheology. But texture is much harder to describe in terms of our perceptions. We use many terms to try to qualify how textures feel, such as watery, sticky, gloopy, jelly-like, 'as thick as treacle' and 'like whipped cream'. It can therefore be a real challenge for formulators to satisfy a customer's requirements when asked to create a product with ( or without) certain textures. If a customer just wants viscosity, this is fairly easy to quantify in terms of standard units ( usually millipascal-seconds or centipoise), such as : "We need a viscosity of 2000 mPa". But formulating becomes more difficult when the customer also has criteria based on how the product needs to feel and how it should interact with the skin. Note de contenu : - Shampoos

OsmolytesLes osmolytes sont de petites molécules de matière organique, solubles dans la solution intracellulaire, qui jouent un rôle dans la lutte contre les stress liés à l'environnement chez les organismes vivants. Dans de nombreux cas, les stress environnementaux menacent la stabilité de la conformation des protéines et donc divers osmolytes ont été sélectionnés pour stabiliser les macromolécules intracellulaires.
Peau -- Soins et hygièneIndex. décimale : 668.5 Parfums et cosmétiques Résumé : This article focuses on myo-inositol and describes the many versatile functions of this ingredient in particular how it is involved in the regulation of three main elements i skin : energy, oxygen and water.
This is reflected and supported by an improved skin elasticity of the face in a large clinical test where an O/W cream with 3% myo-inositol was applied for 5 weeks and compared to a placebo cream and to the stard of treatment.Note de contenu : - Energy : Myo-inositol as stimulator of cell growth and cell metabolism
