INCI name : Cetyl Dimethicone

Model: NV-PC423

Chemical Information:

Main Composition: Cetyl Methyl Siloxane - Dimethyl Siloxane Copolymer

Chemical Character: An alkyl-modified silicone fluid where a long-chain cetyl group (C16) is grafted onto the silicone backbone.

Molecular Structure:

[(CH₃)₃SiO_1/2]₂ [(CH₃)₂SiO]_m [R(CH₃)SiO]_n

Where R represents the Cetyl (C16) alkyl chain.

Cas No.:191044-49-2

Product Description:

NV-PC423 an alkyl-modified silicone fluid where a long-chain cetyl group (C16) is grafted onto the silicone backbone. This modification significantly enhances its compatibility with organic ingredients, vegetable oils, and waxes. It functions as an excellent emollient, providing a long-lasting, silky skin feel, improved water resistance, and a reduction in the "whitening effect" often seen in emulsions.

NV-PC423 can serve as a partial alternative to traditional low-viscosity silicone fluids, providing a balanced sensory profile with improved substantivity and reduced greasiness.

Typical Properties:

Appearance:colorless and light yellow clear liquid.

Viscosity(25℃,mm².s):200-400cst

Refractive Index (25℃):1.430-1.440

Non-volatile content ≥95%

Specific gravity(25℃):0.90-0.93

Key Benefits & Features:

Superior Compatibility: Excellent solubility in many organic oils and cosmetic esters compared to standard dimethicone.

Enhanced Emolliency: Provides a rich, smooth, and non-greasy skin feel with lasting substantivity.

Water Repellency: Forms a hydrophobic film on the skin, enhancing the water resistance of sunscreens and barrier creams.

Anti-Whitening: Helps eliminate the "soaping effect" (white streaks) during the application of O/W creams.

Pigment Wetting: Improves the dispersion and stability of pigments in color cosmetics.

UV stability: Its structure is stable under UV exposure, making it especially suitable for sun care and long-wear cosmetics.

Applications:

Skin Care: Moisturizing creams, body lotions, and protective barrier ointments.

Color Cosmetics: Foundations, lipsticks, and eye makeup where pigment dispersion and shine are required.

Sun Care: Water-resistant sunscreen lotions and tanning oils.

Hair Care: Leave-on treatments and brilliantine-style products for enhanced gloss.

Formulation Guide:

Solubility: Soluble in isopropyl myristate, mineral oil, silicone fluids and most cosmetic esters,but insoluble in water.

Phase Addition: Should be added to the oil phase of the formulation;post-addition is also possible depending on formulation design.

Process Temperature: Stable at typical emulsion processing temperatures (up to 80°C).

Compatibility Note: It can act as a "compatibilizer" between silicone fluids and organic oils in complex formulations.
