INCI name : Decamethyltetrasiloxane

Model: NV-PC201-1.5

Chemical Information:

Main Composition: Decamethyltetrasiloxane

Chemical Character: Volatile Methyl Siloxane (VMS)-A linear siloxane consisting of four silicon atoms and ten methyl groups.

Molecular Structure: CH3[Si(CH3)2O]3Si(CH3)3

Cas No.:141-62-8

Product Description:

NV-PC201-1.5 a clear, colorless, and odorless linear polydimethylsiloxane fluid. It is a highly pure, volatile silicone characterized by its low viscosity and fast evaporation rate. It serves as a functional alternative to cyclomethicones (like D4 or D5) in applications where a linear structure or specific volatility profile is preferred.

Typical Properties:

Appearance:Colorless transparent liquid

Odor:Odorless

Refractive index (25°C): 1.388 – 1.390

Specific Gravity (25°C):0.854

Purity (GC):≥99%

Viscosity:1.5cst

Flash Point (Closed cup):68°C

Surface tension(25°C):18.0 mN/m

Key Benefits & Features:

 Controlled Volatility: Evaporates completely at room temperature without leaving oily residue or buildup.

 Superior Spreadability: Extremely low surface tension allows for rapid and even wetting of surfaces.

 Non-Staining: Ideal for applications where fabric or surface staining must be avoided.

 Low Heat of Vaporization: Does not produce a significant "cooling effect" on the skin during evaporation compared to lower alcohols.

 Excellent Carrier: Acts as an effective carrier for active ingredients, pigments, and fragrance oils.

Applications:

 Personal Care: Used in hair sprays, skin cleansers, and "dry" body oils to improve spread and reduce greasiness.

 Industrial Cleaning: An effective, environmentally friendly cleaning agent for electronics and precision metal parts.

 Carrier Fluid: Used in specialty lubricants, coating formulations, and household products (e.g., glass cleaners).

 Solvent: Acts as a volatile solvent in silicone-based adhesives and sealants.

Formulation Guide:

 Compatible with most anhydrous alcohols and many common organic solvents used in cosmetics.

 Should be incorporated into the oil phase.

 Due to its flash point (68°C), avoid heating above 50°C in open vessels; if heating is required, ensure it is done in a closed system to prevent loss and ensure safety.

Recommended Usage Level:

Cosmetic Formulations: 1% – 20%

Cleaning & Industrial: 20% – 100% (depending on application)

Solvent/Carrier: 5% – 50%

Handling & Precautions:

Flammability: Classed as a combustible liquid. Keep away from heat, sparks, and open flames.

Static Discharge: Ground equipment during transfer to prevent static ignition.

Ventilation: Use in well-ventilated areas to avoid inhalation of vapors.

Packaging & Shelf Life:

Packaging: Typically supplied in 160kg drums or 800kg IBC tanks.

Shelf Life: 24 months when stored in the original, unopened container at room temperature (below 30°C). Keep away from direct sunlight.
