Trimethylsiloxysilicate is a silicone-based polymer widely used in cosmetic, skincare, and sun care formulations. It belongs to the class of MQ silicone resins, composed of monofunctional (M) and tetrafunctional (Q) siloxane units, which give it a unique combination of flexibility and rigidity. This ingredient forms a durable, water- and sebum-resistant film on the skin or hair, enhancing the longevity and performance of cosmetic products.
Its solvent-free, non-tacky nature makes it easy to formulate with, while its compatibility with both silicone and organic carriers allows for versatile applications. Trimethylsiloxysilicate also offers potential SPF enhancement in sun care products and improves resistance to smudging, transfer, and wash-off in color cosmetics.
