In cosmetic formulations such as make-up, skin care, and hair care products, formulators often face several challenges. Products may suffer from poor wear resistance, limited water resistance, migration of oils or pigments, and insufficient gloss. Under conditions such as heat, sweat, or long wear, maintaining both durability and a pleasant sensory feel can be difficult.

To address these challenges, film-forming silicone resin systems are commonly introduced into formulations. By forming a thin and uniform film on the surface of skin or hair, these materials can significantly improve product durability, water resistance, and overall performance.

IOTA 91003 is a silicone resin blend designed for such applications. It consists of Trimethylsiloxysilicate dispersed in volatile cyclomethicone. The volatile carrier provides excellent spreading during application, and after evaporation, the MQ silicone resin forms a flexible and durable film on the surface.

This structure offers several performance benefits, including:

• Formation of a stable protective film on skin or hair

• Improved long-lasting performance in make-up formulations

• Enhanced resistance to water and washing

• Reduced migration in cosmetic systems

• Natural glossy appearance

Because the formulation contains volatile silicones, it is generally recommended to incorporate the product at temperatures below 50°C during processing to maintain its properties.

IOTA 91003 can be used in a wide range of personal care formulations, including:

• Make-up products

• Skin care products

• Hair care formulations

By incorporating this silicone resin system into formulations, manufacturers can improve durability, water resistance, and sensory performance without compromising the lightweight feel of the final product.
