Viscosity(25℃,mPa.s):12-18

Refractive index(nD25):1.490-1.505

Flash point（closed cup,℃）:>100

Specific gravity(25℃):0.98-1.02

Odor:Characteristic slight odor

Key Benefits & Features

Ultra-High Gloss: With a refractive index near 1.50, it provides a "brilliant shine" effect in lipsticks and hair care products.

Enhanced Compatibility: Better solubility with UV filters, mineral oils, and fatty acid esters compared to standard dimethyl silicone oils.

Superior Skin Feel: Imparts a silky, velvety texture without the tackiness associated with high-viscosity fluids.

Improved Dispersion: Acts as an excellent wetting agent for pigments (Iron Oxides) and sun filters (TiO2), ensuring uniform color distribution.

Moisture Retention: Forms a breathable, water-repellent film that helps maintain skin hydration.

Applications

Color Cosmetics: Premium lipsticks, lip glosses, liquid foundations, and highlighters.

Hair Care: Hair serums, shine sprays, and leave-in conditioners (provides instant luster).

Sun Care: High-SPF sunscreens and tanning oils (improves UV filter solubility).

Skin Care: Anti-aging creams, luxurious body lotions, and facial oils.

Handling & Precautions

Safety: Avoid direct contact with eyes. In case of contact, rinse immediately with water.

Storage: Store in the original airtight container at temperatures below 25°C.

Compatibility Note: While highly compatible, always conduct a stability test when mixing with high concentrations of paraffin wax or extreme polar oils.

Packaging & Shelf Life

Standard Packaging: 200kg drums. Custom packaging available upon request.

Shelf Life: 24 months from the date of manufacture when stored correctly.

Re-evaluation: After the expiration date, the product may still be usable following a quality re-test of the refractive index and viscosity.
