SiBrid® DIETHICONE DE-15 (DE-15) is a light emollient with a soft, cushion-like skin feel. It imparts excellent slip and spreading properties in skin care and color cosmetics. In water-in-silicone foundations and pressed powders, this product serves as an excellent vehicle for wetting pigments. It exhibits far greater compatibility with common cosmetic ingredients than dimethicone fluids.

Product Highlights

PolydiEthylsiloxanes (DiEthicones) are the first of a series of hybrid silicone polymers without methyl substitution. Analogous in structure to DiMethicones, the flexible polymer structure of DiEthicones allows the manufacture of a wide range of fluid viscosities. The beneficial properties of DiEthicones include excellent spreading, gas permeability, water resistance, lubricity and the ability to reduce tack. DiEthicone’s tactile properties include a dry feel similar to that of DiMethicone but with increased cushion. DiEthicones have dramatically broad compatibility with organics compared to DiMethicones, allowing formulation with common cosmetic raw materials including many hydrocarbons, esters, waxes and surfactants. DiEthicones overcome the solubility limitations of DiMethicones with many surfactants, emollient oils and both natural and synthetic waxes. DiEthicones, in contrast to DiMethicones, wet pigments well. The greater organic character of DiEthicones allows coated pigments and fillers to disperse more readily in organic vehicles allowing either higher pigment volume concentration at equivalent formulation viscosities or substantially lower viscosities at equivalent pigment loadings.

Pigment Wetting
