| Résumé : |
Repair, protect and moisture are the key consumer requirements in skin care. The components that help achieve these claims are often either monovalent or multivalent electrolytes, such as salts of alpha hydroxy acids, sodium pyrrolidone carboxylic acid (sodium PCA), phenylbenzimidazole sulfonic acid (PBSA), etc. However, it is difficult to formulate with these actives since they tend to have a negative effect on the viscosity, texture and stability provided by commonly used traditional anionic rheology modifiers.
Sodium acrylates/beheneth-25 methacrylate crosspolymer (and) hydrogenated polydecene (and) lauryl glucoside, is a multifunctional polymer based on acrylate chemistry that enables the formulation of smooth and elegant emulsions containing high levels of electrolytic active ingredients by offering excellent efficiency as a thickener, stabiliser, and primary or auxiliary emulsifier, with improved electrolyte tolerance and unique sensory properties. It offers excellent viscosity building and yield value across a range of polymer solids providing stabilisation and suspension properties in finished formulations ranging from low viscosity lotions to high viscosity creams. |
