Title
(EN) AMINO-ACID FUNCTIONAL SILOXANES, METHODS OF PREPARATION AND APPLICATIONS
(FR) SILOXANES PORTANT UNE FONCTION AMINOACIDE, MÉTHODES DE SYNTHÈSE ET APPLICATIONS
Abstract
(EN)
A method of preparing an amino acid functional siloxane by reacting an amino acid derivative selected from the group of an N-acyl amino acid and an N-aroyl amino acid with an amino functional siloxane optionally in the presence of a solvent. The invention extends to personal care products containing the resulting amino acid functional siloxanes.
(FR)
La présente invention porte sur une méthode de synthèse d'un siloxane portant une fonction aminoacide par réaction d'un dérivé d'acide aminé sélectionné au sein du groupe constitué par un acide aminé N-acylé et un acide aminé N-aroylé, avec un siloxane portant une fonction amine, éventuellement en présence d'un solvant. La présente invention englobe les produits de soins personnels contenant les siloxanes portant une fonction aminoacide résultants.
