Zusammenfassung: | 1. The invention relates to a high SPF/UVAPF sunscreen composition. Optionally the composition has: a) 0.1 to 5 % w/w dibenzoylmethane or its derivative; b) 0.1 to 5 % w/w non-ionic surfactant selected from the class of ethoxylates of fatty alcohol/ fatty acid with saturated carbon chain and having HLB greater than 15.5 or from the class of ethoxylates of fatty alcohol / fatty acid with unsaturated carbon chain with HLB greater than 12; c) 0.1 to 0.5 % w/w of a polymer selected from the class of acrylate / R-methacrylate copolymer or crosspolymer, or an acrylate / R-alkyl acrylate crosspolymer; or from 0.2 - 0.5 % w/w of a polymer selected from the class of copolymers of acryloyldimethyltaurate with vinyl pyrrolidone, methacrylate or R-alkyl acrylate, and d) a cosmetically acceptable base, where R and alkyl are C10-30 alkyl groups.
L'invention concerne une composition d'écran solaire à SPF/UVAPF élevés La présente invention concerne une composition d'écran solaire photo-protectrice à SPF élevé (supérieur ou égal à 15) ou à UVAPF élevé (supérieur ou égal à 4), qui ne compromet pas les propriétés sensorielles souhaitées sur la peau, tout en utilisant des quantités relativement faibles d'agents d'écran solaire et en maintenant ainsi les coûts bas. |
