Product Name:Silicone emulsifier NV-PC8091

INCI: Cyclopentasiloxane (and) PEG/PPG-18/18 Dimethicone

Chemical Informations:

Main Composition:Cyclopentasiloxane; PEG/PPG-18/18 Dimethicone

Molecular Structure:

R−[Si(CH₃)₂−O]_m−[Si(CH₃)(R′)−O]_n−R

R′: Polyether chain

Chemical Character: Non-ionic Silicone Emulsifier Blend.The active emulsifier is a cross-linked or high molecular weight "EO/PO" modified silicone. The presence of both Ethylene Oxide (PEG) and Propylene Oxide (PPG) groups provides a dual-action hydrophilic-lipophilic balance that is more robust than PEG-only surfactants.

Product Description:

NV-PC8091 is a specialized dispersion of a high molecular weight silicone polyether in Cyclopentasiloxane. It serves as a dedicated emulsifier and dispersing agent for Water-in-Cyclomethicone (W/Si) and Water-in-Oil (W/O) systems. It acts as a bridge between polar and non-polar ingredients, allowing non-polar components to dissolve in the external silicone phase while polar active ingredients are sequestered in the internal water phase.

Typical properties:

Appearance:milky white liquid

Density(25℃):0.930~0.970:

Viscosity（cSt,25℃）:40~125

Solid content (%,120℃×2h):10~14

Key Benefits & Features:

Superior Emulsion Stability: Acts as a powerful stabilizer for W/O and W/Si systems, preventing phase separation even in low-viscosity formulas.

Optical Clarity: Helps in achieving "crystal clear" or highly translucent oil-phase appearances in complex formulations.

Dual Solubilization: Facilitates the uniform dispersion of polar actives (vitamins, extracts) and non-polar emollients within the same system.

Excellent Aesthetics: Imparts a signature "velvety" or "powdery" dry-down effect; reduces the greasiness associated with organic oils.

Film Forming: Provides a breathable, water-resistant barrier on the skin.

Applications:

Color Cosmetics: Liquid foundations, primers, and "long-wear" concealers.

Skin Care: Lightweight night creams, eye gels, and anti-aging serums.

Sun Care: Water-resistant sunscreen lotions and sprays.

Antiperspirants: Roll-ons and gels where high salt stability is required.

Formulation Guide:

Phase Preparation: Mix the emulsifier blend thoroughly into the silicone/oil phase (external phase) before starting the emulsification.

Water Addition: Slowly add the water phase (internal phase) to the silicone phase under high-speed stirring or homogenization.

Cold Process: This blend is ideal for cold processing, which preserves heat-sensitive active ingredients.

Salt Addition: For maximum stability, add 0.5% – 2.0% Sodium Chloride or Magnesium Sulfate to the water phase to balance the osmotic pressure.

Clarity Tip: To achieve a clear W/O emulsion, the refractive indices of the water and oil phases must be matched precisely (RIwater ≈ RIoil).

Dosage:

As Primary Emulsifier: 5.0% – 15.0% (depending on the water-to-oil ratio).

As Co-emulsifier/Stabilizer: 1.0% – 5.0%.

Handling & Precautions:

Flammability: Contains volatile silicones; keep away from heat, sparks, and open flames.

Volatility: Ensure the container is tightly sealed after each use to prevent changes in concentration due to evaporation of the D5 carrier.

Packaging & Shelf Life:

Packaging: 25kg plastic pails or 200kg iron drums.

Shelf Life: 12 months from manufacturing date when stored in the original sealed container under recommended conditions.
