IOTA 91002 Trimethylsiloxysilicate is a highly crosslinked silicone resin designed for modern cosmetic formulations. It is produced through the co-hydrolysis of alkyl siloxanes and trimethylsiloxane components, creating a structured resin containing small amounts of alkoxy and hydroxyl groups.

One of its key advantages is its ability to blend with volatile silicones and low-viscosity dimethicone, providing formulators with flexibility when developing different cosmetic systems.

IOTA 91002 offers a combination of rheology control, hydrophobicity, film-forming ability, and moisturizing properties. After application, it can form a durable film that helps maintain the desired sensory and functional effects over time.

The resin is particularly suitable for makeup, skincare, sunscreen, and haircare products. In color cosmetics, its film-forming characteristics can help improve product adhesion and durability, while its hydrophobic properties support resistance to water exposure.

The recommended addition level for color cosmetics is generally 2–10%, depending on the desired formulation performance.

With its combination of silicone compatibility, film formation, water resistance, and formulation versatility, IOTA 91002 is a useful ingredient for developing high-performance cosmetic products.
