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.Note de contenu : - METHODS AND MATERIALS : General performance (viscosity and yield value - Viscosity and yield blue - Electrolyte tolerance - Sensory evaluation at equilibrium pH - Emulsification and co-emulsification property - Thickening/stabilising systems with challenging electrolytic electrolytic actives

GalactomannaneLe galactomannane est un polyoside (polymère d'ose) présent dans de nombreuses graines.
Le galactomannane est une fibre végétale soluble et acalorique présente dans les graines et sert de réserve de sucre lors de la germination. Elle est abondante dans l’albumen de graines de légumineuses, telle que la cyamopsis tetragonoloba1, de la Caesalpinia spinosa et de la Ceratonia siliqua.
Le galactomannane est un polymère linéaire composé d'une chaine de monomères de mannose ((1,4)-beta-D-mannopyranose) auxquelles sont ramifiés par un pont 1-6 une unité de galactose.
Les galactomannanes sont utilisés dans l'agro-alimentaire pour modifier la viscosité et la texture des aliments (boissons, crême glacée,...). Ils sont utilisés sous forme de gomme naturelle : gomme de guar (E412), gomme tara (E417) et gomme de caroube (E410).

Tara et constituantsC'est un petit arbre épineux avec des gousses plates rouge qui pousse dans les zones sèches du Pérou, Amérique du Sud.Index. décimale : 668.5 Parfums et cosmétiques Résumé : Tara gum, a galactomannan derived from the seeds of the Caesalpinia Spinosa plant, is known for its high thickening capability, good solubility, and synergistic behavior with other hydrocolloids. While it has been widely used in the food industry as a stabilizer, thickener, and texturizer, its potential in the cosmetic industry is still being explored.
This article studies the use of tara gum in various cosmetic applications, more specifically hair care products such as conditioners, treatments and styling formulations.
The thickening ability and sensory contribution were assessed in hair conditioners. Tara gum’s styling performance was also evaluated by measuring the curl retention under high humidity conditions and hair stiffness. Additionally, a particle adhesion test simulated its effectiveness as a shield against pollution. Finally, associations with other synthetic or natural-derived polymers were explored.
The results showed tara gum’s effectiveness in various hair care formulations. It enhanced viscosity and stability in conditioners, improved curl retention and resistance to high humidity in styling products, and reduced particle adhesion for pollution-resistant formulations. Synergies in combination with naturally derived and synthetic polymers were also demonstrated, with improved thickening or film-forming performance.
Overall, these findings highlight tara gum’s potential as a natural and sustainable ingredient for high-performance and environmentally friendly cosmetic products.Note de contenu : - MATERIALS AND METHODS : viscosity and yield value - Sensory analysis - High humidity spiral curl retention - Stiffness - Pollution simulation : particle adhesion
