Peau -- Soins et hygièneIndex. décimale : 668.5 Parfums et cosmétiques Résumé : When it comes to formulating personal care products, it is critical to select the most effective anti-bacterial agent. Especially when it comes to preservation, no single preservative is equally effective against all types of microorganisms.
Cetylpyridinium chloride (CPC, Figure 1) is a quaternary ammonium compound that a literature search shows to be biodegradable and which offers effectiveness against many organisms. In the US, it may be used as a preservative and the FDA lists it as an antimicrobial agent. Outside the US, it may be used as an antibacterial agent. CPC has also been used widely in in over-the-counter products including mouthwash, throat lozenges, generally at 0.1-0.2%, nasal sprays and antiseptic (first aid) creams and lotions.
Vertellus offers CPC in two forms : powder and liquid. The trade name for the liquid form is ‘Freshstat™ Cetylpyridinium Chloride’ and it is a 40% CPC in propylene glycol solution. This form provides formulation ease and production flexibility. Our CPC is made in the USA, comes in US and European Pharmacopeia forms, and also in technical grades.
Based on common knowledge of commonly used preservatives, Table 1 compares a 40% CPC solution in propylene glycol to a variety of commonly used preservatives, i.e. methylparaben, ethyl paraben, propylparaben, butylparaben, phenoxyethanol, imidazolidinyl urea and chlorphenesin. This shows that CPC is effective over a broad pH range and exhibits broad anti-microbial efficacy against grampositive and gram-negative bacteria, broad spectrum activity, where the others have activity against fewer of these microorganisms.Note de contenu : - Anti-microbial activity

Produits chimiques -- BiodégradationIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Rheology modifiers are functional skincare ingredients that work to thicken formulations. They are primarily used to impart a thicker texture and viscosity to topical formats, such as creams, serums, and gels.
Rheology modifiers have a resultant impact on the experience of using a product, influencing the way it feels on skin during and after use, as well as its look and pick-up texture. Beyond a formulation’s initial texture, rheology modifiers will determine the maintenance of texture, viscosity, and flow across temperature and pH ranges. They will also work to stabilize oils and other particles included in a formulation, acting as structuring agents that help various components to combine with each other.
Nowadays, skincare is increasingly associated with wellness and practiced as a means by which to relax. In addition, consumers are ever-more educated on its benefits, layering different products to achieve and optimize the results of their routines. Therefore, the emphasis placed on rheology modifiers continues to grow as cosmetic brands need to ensure they can provide an enjoyable sensory experience.
In addition to performance, rheology modifiers have an environmental impact, contributing to a formulation’s overall carbon footprint as well as to its biodegradability. As skincare formulations end their lifecycles in water, the biodegradability of rheology modifiers is an important factor in reducing build-up in the environment.Note de contenu : - Rheology modifier options

Lamine (biologie)La lamine est une protéine qui forme la lamina nucléaire.
Les lamines A(70kDa), B(67kDa) et C(60kDa) forment cette lamina dans toutes les cellules eucaryotes : ce sont des filaments intermédiaires nucléoplasmique de type V qui participent à la structure du noyau et aux liaison chromatine/membrane nucléaire. Elles interviennent également dans les processus de mitose (phosphorylation des lamines entrainant la disparition de l'enveloppe du noyau), de différenciation cellulaire (lamine B remplacée par des lamines A) et de mort cellulaire (dégradation des lamines par les caspases 6 engendrant une cascade de réactions entrainant l'apoptose).

TélomèresUn télomère est une région hautement répétitive, donc non codante, d'ADN à l'extrémité d'un chromosome. À chaque fois qu'un chromosome en bâtonnet d'un eucaryote est dupliqué, lors de la réplication, qui précède la mitose (division cellulaire), le complexe enzymatique de l'ADN polymérase s'avère incapable de copier les derniers nucléotides : l'absence de télomère signifierait la perte rapide d'informations génétiques nécessaires au fonctionnement cellulaire.
Les télomères raccourcissent avec l’âge, l’inflammation et le stress. Des études ont montré que des télomères courts sont associés à un risque plus élevé de maladies liées à l’âge.Index. décimale : 668.5 Parfums et cosmétiques Note de contenu : - A unique approach : telomeres and the shelterin complex

ThixotropieIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Hypochlorous acid (HClO) is formed in the white blood cells of all mammals. As part of a mechanism that developed several millions of years ago, it also helps the human body to protect against pathogens that enter it. This makes the weak acid a nature-based option for disinfection. Despite this, a disadvantage of water-thin solutions of hypochlorous acid is that they have significantly limited anti-microbial potential due to the reduced contact time. Hydrogels overcome this limitation and lead to improved and more sustainable use. Due to the high reactivity of hypochlorous acid, common additives such as polymer thickeners and natural clays are not suitable. Synthetic smectite clays – of which the presented PURABYK-R 5500 is one example – are very similar in structure to natural clays. However, due to their subsequent technical development, synthetic smectite clays exhibit better stability and are therefore very well suited to forming these hydrogels. They stabilize the hypochlorous acid in the required pH value range and are free from components that impair the activity of HClO. These unique additives are produced under controlled conditions from naturally occurring inorganic mineral sources. They offer the possibility of using structures from nature, paired with a very high purity and consistent quality. Their great potential is presented here using PURABYK-R 5500 as an example.

PhospholipidesIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Choosing the right emulsifier is crucial for the success of a formulation. Biophilic H is a naturel phospholipid-based emulsifier with highly desirable properties. Its biomimetic lamellar structure guarantees strong biocompatibility and optimal skin tolerance. It is a performant emulsifier, capable of emulsifying up to 30% all on itself and compatible with all kinds of alls, pigments, as well as chemical and physical UV filters. its content in saturated lecithin provides important thickening properties and allow the formulation of white and odorless emulsions of various consistency, from cream to butter, with excellent spreadability. it also texturises formulations with a soft cashmere touch.
Biophilic H is more than a performant emulsifier. it also acts as an efficient delivery system assuring more effective and faster diffusion of actives. On top of that, it has biological activities that help maintain skin functions, such has hydration and berner function. lt also shows immediate skin smoothing action and preserves skin brightness balance. It additionally brings an outstanding and unique sensory profile as soft and sophisticated as cashmere, even allow percentage. Emotionally approved by consumers, it triggers pleasure and wellbeing upon application.
Biophilic H can be associated with advertising claims such as : natural engin, biodegradable, sustainable engin, RSPO certified ingredient (available with the MB grade : Biophilic H MB), safe materials and GRAS-status (generally recognized as safe)Note de contenu : - TECHNICAL CHARACTERISTICS : Biocompatibility - Lamellar structure - Formulation characteristics
