Cosmetic sun protection product based on W/Si-emulsions
View Patent ↗The invention relates to a cosmetic sun protection product based on W/Si emulsions, which product has improved effectiveness and, despite high content of organic sun protection filters, a very good sensory profile and, in particular, a long-lasting soft touch. The sun protection product includes 22-32 wt. % of a volatile, cyclic silicone oil, 2.0-4.0 wt. % of a non-volatile silicone elastomer, 0.9-2.8 wt. % of an emulsifier, 0.1-0.5 wt. % of an amino acid/fatty acid copolymer, 19-24 wt. % of a mixture of organic UVA and UVB filters at a ratio of from 1:1.5 to 1:1; and cosmetic adjuvants, excipients, active substances and mixtures thereof to make 100 wt. %, the Brookfield viscosity of the sun protection product ranging from 3,000 to 20,000 mPas.
