Phenyl Trimethicone Luster Emollient Silicone-CAS 2116-84-9
Phenyl Trimethicone is a high-purity cosmetic grade silicone oil refined by advanced silicon-oxygen bond polymerization 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 single luster effect and poor skin affinity, and ordinary ester emollients with weak weather resistance and easy to lose luster, Phenyl Trimethicone has a unique phenyl-modified silicone molecular structure, which has silky smooth texture, excellent spreadability and fast skin absorption.
It can quickly spread on the skin surface to form a thin and breathable protective film, not only softening skin texture and reducing skin friction, but also bringing a natural and delicate luster to the skin, making the skin look radiant and translucent.
As a multi-functional silicone emollient integrating luster enhancement, moisturizing and UV resistance, it can effectively improve the luster of skincare and makeup products, enhance the fitting degree of makeup, and form a protective barrier on the skin and hair surface to resist UV damage and external environmental irritation.
The product has excellent chemical stability and weather resistance, 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 high-gloss skincare, premium makeup and mild care cosmetic formulas.
