INCI Name :Methyl Trimethicone

Model name: NV-PC211

Chemical Information

Main Composition: Methyl Trimethicone (Polymethylsilsesquioxane)

Molecular Structure:(CH3)3SiO-Si(CH3)(OSi(CH3)3)2

Chemical Character: It is a branched-chain volatile silicone fluid, specifically a low molecular weight methyl-substituted siloxane.

Cas No.:17928-28-8

Product Description:

NV-PC211 is a high-purity, volatile, branched-chain silicone fluid. It serves as an ideal alternative to Cyclopentasiloxane (D5) in formulations where high volatility and a light, non-greasy skin feel are required. Due to its branched structure, it offers unique spreadability and a refreshing sensory profile, leaving no residue on the skin or hair.

Typical Properties:

Appearance:Colorless, odorless, transparent liquid

Viscosity (25°C, cSt):1.0–2.0 cSt

Refractive Index :1.380–1.390

Specific Gravity (25°C):0.845–0.855

Key Benefits & Features

 Excellent Volatility: Evaporates quickly without a cooling sensation, facilitating "fast-dry" formulations.

 Superior Spreadability: Low surface tension allows for easy distribution of pigments and actives.

 Non-Greasy Feel: Provides a silky, smooth, and powdery after-feel.

 D5 Replacement: A popular choice for brands seeking D5-free alternatives in personal care.

 High Compatibility: Compatible with a wide range of organic oils, waxes, and other silicones.

Applications:

 Color Cosmetics: Foundations, concealers, lipsticks, and eye make-up (improves transfer resistance).

 Skin Care: Light lotions, facial serums, and sunscreens (reduces tackiness).

 Hair Care: Hair oils, leave-in conditioners, and styling products.

 Antiperspirants/Deodorants: Provides lubrication and quick drying.

Dosage:

Skin Care: 1%–10%

Color Cosmetics: 5%–50%

Hair Care: 1%–5%

Note: Specific dosage depends on the desired evaporation rate and sensory requirements of the final formula.
