IOTA 91002 Trimethylsiloxysilicate is a high-performance silicone resin widely used in cosmetic formulations. It is supplied as a solid powder and can be dissolved in silicone fluids or compatible organic solvents before use.

Thanks to its excellent film-forming ability and hydrophobic properties, this material provides long-lasting performance in a variety of personal care products.

Unlike traditional resin systems that may contain aromatic solvents such as toluene or xylene, IOTA 91002 is produced using an environmentally friendly process. It can be blended easily with volatile silicones and low-viscosity silicone oils, making it convenient for cosmetic formulation.

Key Features

• Excellent compatibility with many organic solvents and silicone fluids

• Strong film-forming ability

• Outstanding water repellence

• Good resistance to detergent wash-off

• Environmentally friendly production process

Benefits in Cosmetic Formulations

When used in personal care formulations, IOTA 91002 can help improve product durability and performance. The silicone resin forms a flexible and uniform film on the skin or hair surface, which enhances water resistance and helps cosmetic products stay in place for longer periods.

In makeup formulations, it can contribute to better adhesion, smoother application, and improved wear resistance. In skin care and sunscreen products, it provides hydrophobic protection while maintaining a comfortable skin feel.

Typical Applications

IOTA 91002 is widely used in various cosmetic products, including:

• Sunscreen formulations

• Protective skin care products

• Facial makeup products

• Lotions and creams

• Color cosmetics

• Hair treatment products

Recommended Use

Before use, IOTA 91002 should be pre-mixed with a suitable solvent. Low-viscosity silicone oil or cyclopentasiloxane are commonly recommended solvents. The prepared solution can then be added into the oil phase of cosmetic formulations.

Typical recommended dosage:

• Color cosmetics: 2–10%

• Hair care products: 0.5–5%

Typical Properties

• Appearance: White solid powder

• Bulk density: 0.56–0.61 g/cm³

• Volatility (150°C, 3 h): ≤2%
