COSMETIC FORMULATIONS CONTAINING BALANCED MIXTURES OF NATURAL-ORIGIN ANIONIC POLYMERS AND PROCESS FOR TOPICAL APPLICATION OF SAME

摘要

Cosmetic formulations containing balanced mixtures of natural-origin anionic polymers, made up of a gel material consisting of a balanced mixture of anionic polysaccharides of natural origin containing 0.1 % to 5 % of a soluble alginate, 0.01 % to 0.5 % of agar, 0.01 % to 0.5 % of pectin and 0.05 % to 1 % of xanthan gum, the balance being water. The process for topical application of the gel material comprises the following operating steps: spreading a polysaccharide matrix of said gel material over a plate; levelling said polysaccharide matrix to a homogeneous layer of predetermined thickness; dipping said plate into a 1 % calcium salt solution for about 5 minutes; subsequently dipping said plate into a 2 % calcium salt solution for about 2 minutes; thereby obtaining a structured gel provided with a physical pattern of its own; separating said structured gel from said plate; subsequently washing said structured gel in distilled water.
