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.
