Abstract:
1. A sun protection composition comprising at least one polyurethane urea obtained by A) preparing water-insoluble, non-water-dispersible, isocyanate-functional polyurethane prepolymers A) from and B) then reacting some or all of their free NCO groups with at least one amino-functional compound B), comprising at least one amino-functional compound B2) which comprises one or more ionic and/or ionogenic groups, wherein the at least one polyurethane urea is dispersed in water during or after step B), wherein the isocyanate-functional polyurethane prepolymers A) have a content of ionic and ionogenic groups below 1 milliequivalent per 100 g of polyurethane prepolymers, and wherein said sun protection composition comprises a total of 16 to 35% by weight of one or more sun protection filter substances, based on the total weight of said sun protection composition, and at least one of said sun protection filter substances is octocrylene which is present in an amount of from 4 to 12% by weight, based on total weight of said sun protection composition, wherein the at least one polyurethane urea has repeat units containing urea groups, which are formed in the reaction of the isocyanate-functional prepolymers A) with the at least one amino-functional compound B), and wherein the sun protection composition has a Sun Protection Factor (SPF) boosting effect.
