INCI name : Lauryl Dimethicone

Model: NV-PC422

Chemical Information:

Main Composition: Lauryl Methyl Siloxane - Dimethyl Siloxane Copolymer

Chemical Character: An alkyl-modified silicone fluid where a long-chain Lauryl group (C12) is grafted onto the silicone backbone.

Molecular Structure:

[(CH₃)₃SiO_1/2]₂ [(CH₃)2SiO]m [R(CH₃)SiO]n

Where R represents the Lauryl (C12) alkyl chain.

Product Description:

NV-PC422 is a specialized silicone fluid modified with a long-chain lauryl group (C12). This modification provides an ideal balance of silicone silkiness and organic oil compatibility. With a medium-low viscosity (50–100 cSt), it offers a lighter and more spreadable feel than heavier alkyl silicones, making it an excellent emollient and pigment wetting agent for premium personal care products.

Typical Properties:

Appearance:colorless and light yellow clear liquid.

Viscosity(25℃,mm².s):50-100cst

Refractive Index (25℃):1.415-1.435

Non-volatile content ≥95%

Specific gravity(25℃):0.90-0.93

Key Benefits & Features:

Superior Compatibility: Higher solubility in paraffin oil, vegetable oils, and organic solvents compared to standard dimethicones.

Light & Silky Texture: Provides a refreshing, non-greasy moisturizing effect with excellent skin-friendliness.

Pigment Dispersion: Effectively wets and disperses inorganic pigments (TiO2, iron oxides) and sunscreen powders.

Improved Spreadability: Lowers the surface tension of the oil phase, allowing for smoother application and "play-time."

Water Repellency: Enhances the water resistance of sunscreens and long-wear makeup.

Applications:

Skin Care: Daily moisturizers, body lotions, and protective creams.

Color Cosmetics: Foundations, BB/CC creams, lipsticks, and eye makeup.

Sun Care: Sunscreen lotions and oils (ideal for stabilizing mineral filters).

Hair Care: Serums and conditioners for enhanced shine and frizz control.

Formulation Guide:

Solubility: Insoluble in water; soluble in a wide range of cosmetic oils and silicone fluids.

Phase Addition: Typically added to the oil phase.

Versatility: Can be used to replace traditional low-viscosity silicone oils to improve the compatibility of the overall oil phase.

Process Stability: Heat-stable; can be incorporated during the hot-mixing phase of emulsions.
