Cetyl Dimethicone Skin-friendly Emollient Silicone(CAS 27667-45-2)
Cetyl Dimethicone is a high-purity cosmetic grade silicone oil refined by advanced silicon-oxygen bond polymerization, cetyl modification and multi-stage purification technology, which is a core functional raw material widely used in modern high-end cosmetic and personal care industries.
Different from traditional dimethicone with weak skin affinity and easy to cause a sense of "masking" on the skin, and ordinary ester emollients with poor conditioning effect and easy to leave sticky residue, Cetyl Dimethicone has a unique cetyl-modified silicone molecular structure, which combines the advantages of silicone oil and natural fatty alcohols.
It has silky and delicate texture, excellent spreadability and fast skin absorption speed. It can quickly penetrate into the skin cuticle, fit closely with the skin texture, form a thin and breathable protective film on the skin surface, soften skin texture, reduce skin friction, and bring a comfortable and non-greasy skin-friendly touch.
As a multi-functional silicone raw material integrating emollient, conditioning and stabilizing functions, it can not only gently moisturize and soften the skin, but also effectively improve the smoothness and softness of hair, reduce hair frizz and flyaway, and enhance the stability of cosmetic formulations, preventing the product from delamination and precipitation during storage.
The product has excellent chemical stability, can be perfectly compatible with various cosmetic raw materials such as vegetable oils, emulsifiers, silicones, functional active substances and cosmetic pigments, no precipitation or delamination, no oxidation, discoloration or peculiar smell during long-term storage and high-temperature processing, mild and non-irritating, non-sensitizing, non-comedogenic, no harmful impurities, suitable for sensitive skin, oily acne-prone skin, dry skin and infant fragile skin, and is the core raw material for creating mild skincare, sensitive skin care and baby care cosmetic formulas.
