Advanced Physicochemical Profile
Methyl Trimethylsiloxane IOTA 9229 features MT structure with surface tension of 21mN/m, enabling unique volatility. The colorless transparent liquid with refractive index 1.385 forms uniform optical films while maintaining refreshing skin feel. Kinematic viscosity of 1.5mm²/s at 25℃ ensures rapid spreading, complemented by 0.85g/cm³ density for lightweight texture.

Cross-Category Application Evidence
In sunscreen formulations, creates 0.2μm protective films with 18% SPF enhancement. When blended with dimethicone in color cosmetics, achieves 35% improvement in pigment dispersion. Hair care applications with 3% concentration show 22% increase in hair smoothness and 40% reduction in static electricity.
