Title:
COMPOSITION COMPRISING A LIPOPHILIC ORGANIC SCREENING AGENT, A HYDROPHILIC ORGANIC SCREENING AGENT, SPHERICAL PARTICLES OF POROUS SILICA, SPHERICAL PARTICLES OF CELLULOSE, AND AN N-ACYLAMINO ACID POWDER
Document Type and Number:
WIPO Patent Application WO/2024/083568
Kind Code:
A1
Abstract:
The present invention therefore relates to a composition, and in particular a cosmetic or derma- tological composition, comprising: a) at least one lipophilic organic UV screening agent; b) at least one hydrophilic organic UV screening agent; c) at least one filler chosen from spherical particles of porous silica, in particular spherical mi- croparticles of porous silica; d) at least one filler chosen from spherical particles of cellulose; and e) at least one filler chosen from N-acylamino acid powders; the total amount of fillers chosen from spherical particles of porous silica, spherical particles of cellulose and N-acylamino acid powders being between 1% and 4% by weight, preferably between 2% and 4% by weight of the total weight of the composition, and the (spherical particles of cellulose + N-acylamino acid powders )/( spherical particles of porous silica) weight ratio being between 0.25 and 1.
