摘要

The present invention relates to a topical composition comprising a hydrophilic benzimidazole type UVB filter, an organopolysiloxane functionalized with at least one UV-light absorbing group, and highly porous silica and/or highly porous crosslinked polymethylmethacrylate beads having a particle size Dv0 of greater 0.3 μm, a Dv 100 of less than 35 μm, a Dv50 selected in the range of 9 to 15 μm and an oil absorption capacity selected in the range of 1.2-2.5 cc/g. Furthermore the invention relates to the use of such beads to ameliorate the short and long-term sensory properties of a topical composition comprising a hydrophilic benzimidazole type UVB filter and an organopolysiloxane functionalized with at least one UV-light absorbing group.
