The invention provides a 100% anhydrous sunscreen composition and a use of this sunscreen composition with very high water and sweat resistance properties which can be applied on a wet skin, either in the presence of water by repelling water or water droplets respectively or in under-water conditions. The present invention describes a sunscreen composition comprising a silicone organic elastomer blend comprising Dimethicone/Bis-Isobutyl PPG-20 Crosspolymer in Isododecane in a concentration range from about 30% to about 90% w/w and a silicone elastomer comprising Dimethicone/Vinyl Dimethicone Crosspolymer and Silica in a concentration range from about 0.1% to about 10% w/w. The sunscreen may be applied on the skin in the presence of water (in wet and/or under-water conditions). Further, the new sunscreen product allows the consumer to enter water directly after the application of the sunscreen product on his dry or already wet skin.
A method for applying an anhydrous sunscreen composition, said sunscreen having an SPF >=50, 50, 30, or <30, wherein the sunscreen comprises a silicone organic elastomer blend and a silicone elastomer, wherein the silicone organic elastomer blend comprises Dimethicone/Bis-Isobutyl PPG-20 Crosspolymer in Isododecane in a concentration range from about 30% to about 90% of total weight of the composition, wherein the silicone elastomer comprises Dimethicone/Vinyl Dimethicone Crosspolymer and Silica in a concentration range from about 0.1% to about 10% of total weight of the composition, wherein the sunscreen further comprises spherical glass beads comprising soda lime, solid glass microspheres with a mean size of 3.5-5.5 microns, wherein the method comprises:
A sunscreen comprising a silicone organic elastomer blend and a silicone elastomer, wherein the silicone organic elastomer blend consists of Dimethicone/Bis-Isobutyl PPG-20 Crosspolymer in Isododecane in a concentration range from about 55% to about 65% of total weight of the composition, wherein the silicone elastomer comprises Dimethicone/Vinyl Dimethicone Crosspolymer and Silica in a concentration range from about 0.1% to about 10% of total weight of the composition, and wherein the sunscreen further comprises spherical glass beads comprising soda lime, solid glass microspheres with a mean size of 3.5-5.5 microns.
