Silicone elastomer powders, especially crosslinked polymers (and) silicas of polydimethylsiloxane/vinyl polydimethylsiloxane, are important cosmetic raw materials. The preparation process requires a series of complex chemical reactions and physical treatments.
During the preparation process, it is first necessary to cross-link polydimethylsiloxane and vinyl polydimethylsiloxane to form a cross-linked polymer. Then, the silicon dioxide and the crosslinked polymer were combined by specific process conditions to obtain silicone elastomer fine powder.
This powder has many unique properties. First of all, its appearance is a white loose powder, which has a good sense of slipperyness and dispersion. Secondly, it can absorb polar and non-polar oils, reduce the viscosity of the formula, and make the product more refreshing. In addition, the micro powder also has excellent waterproofing and film-forming properties, and can form a protective film to prevent external pollutants from invading the skin.
In cosmetics, silicone elastomer powder is widely used. It can be used as a formula for thickening agent and soft-focusing effect, helping to cover wrinkles and pores, making the makeup more transparent and natural. At the same time, it also enhances the durability of other active ingredients on the skin, providing a lasting soft, smooth and powdery feel to cosmetics.
