Abstract
Silicone-free compositions including hydrocarbons of widely different structures and origins combined with coated particles are provided which have both aesthetic and volatility properties similar to cyclopentasiloxane dispersions. The compositions are useful as full or partial replacement products for dispersions of cyclopentasiloxane, or “volatile silicones.” The compositions are useful in UV-attenuating formulations including skin care products, color cosmetics, pharmaceutical products and especially sun care products such as sunblocks, sunscreens, tanning lotions, and the like.
Claims14
A silicone-free composition comprising:
- a carrier fluid component consisting of about 35% by weight of a first hydrocarbon component selected from a C12-C14 isoparaffin, about 55% by weight of a second hydrocarbon component selected from a C13-C16 isoparaffin, and about 10% by weight of at least one further component selected from the group consisting of a C13-C15 alkane and a cosmetically acceptable oil, and at least one coated particle dispersed in the carrier fluid, the particle selected from a metal oxide, a mineral and a pigment, the silicone-free composition comprising a cosmetically acceptable carrier, wherein the silicone-free composition does not include a wetting agent.
