Abstract

Described herein are topical skin compositions useful for protecting the skin from the sun. The topical skin compositions comprise cosmetic ingredients such as homosalate; octisalate; oxybenzone; octocrylene; avobenzone; C12-15 alkyl benzoate; dicaprylyl carbonate; glycerin; VP / eicosene copolymer; cetearyl alcohol; caprylyl methicone; ceteth-20 phosphate; silica; and ammonium acryloyldimethyltaurate / VP copolymer. The compositions may also comprise other cosmetic ingredients, examples of which include film formers, preservatives, emulsifiers, conditioning agents, and moisturizers. Also disclosed are methods of using the topical skin compositions.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 62 / 023,381, filed July 11, 2014, the contents of which are incorporated herein by reference. technical field [0003] The present invention generally relates to compositions that can be used to protect the skin from the harmful effects of exposure to ultraviolet A (UVA) and ultraviolet B (UVB) radiation from the sun. Background technique [0004] Several skin moisturizing and UV protection compositions are currently available. These compositions suffer from various drawbacks: unpleasant tactile properties (e.g. heavy, greasy or sticky feel), low staying power (e.g. tendency to migrate and pool from the point of application, or to lose weight by performing only one wash). tendency to be easily removed from the skin), insufficient moisturizing and / or UV protection capabilities, and low affinity properties.
