INCI:Trimethylsiloxysilicate

Chemical Information:

Main Composition: Trimethylsiloxysilicate resin (Methyl MQ Resin)

Molecular Structure: [(CH₃)₃SiO_1/2]x [SiO_4/2]_y

Chemical Characterization: A highly cross-linked, three-dimensional network structure consisting of mono-functional "M" units and tetra-functional "Q" units.

CAS No.:68988-56-7

Discription:

NV-PC701 is a high-purity, solid powder silicone resin designed for superior film-forming properties. It creates a durable, uniform, and breathable barrier on the skin and hair. This resin is the industry standard for achieving "non-transfer" and long-wear effects in color cosmetics, providing excellent resistance to water, sweat, and sebum while maintaining a comfortable, non-tacky finish.

Typical product data:

Features and Advantages:

Long-Lasting Performance: Provides exceptional resistance to wash-off, water, and color transfer.

Uniform Film Formation: Due to excellent silicone spreadability, it forms a continuous, flexible film.

Sensory Excellence: Imparts a light, smooth, and comfortable touch; increases softness and shine without stickiness.

Enhanced Stability: Contains minimal alkoxy and hydroxyl groups, ensuring stable performance in various formulations.

Compatibility: Highly compatible with a wide range of silicone fluids and many organic carriers.

Improved Volume: In hair care, it helps increase the sense of volume and provides structural hold.

Application:

Color Cosmetics: Foundations, lipsticks, lip glosses, mascaras, and eyeliners for "all-day" wear.

Sun Care: High SPF sunscreens and sunblocks for enhanced water and sand resistance.

Skin Care: Protective barrier creams, lotions, and insect repellents.

Personal Care: Antiperspirants and deodorants to improve film durability.

Formulation Guide:

Pre-dissolution: The resin must be dissolved in a non-aromatic organic solvent or silicone carrier before use.

Solvent Choice: Recommended for use with volatile silicone oils (e.g., Cyclopentasiloxane/D5) or low-viscosity Dimethicones (1cst–5cst).

Processing: Soak the powder in the carrier until no white powder is visible, then heat to 80–100°C with stirring until a clear, homogeneous solution is achieved.

Addition: Once dissolved, the resin solution can be incorporated into the oil phase of the emulsion or anhydrous system.

Dosage: (Reference only; adjust based on specific formulation requirements)

Color Cosmetics (Lipsticks/Foundations): 11% – 14%

Hair Care: 2% – 10%

Deodorants & Antiperspirants: 3% – 10%

Sun Care: 1% – 5%

Skin Care (Facial/Body): 2% – 4%

Handling & Precautions:

Dust Hazard: As a fine powder, use a dust mask and avoid inhalation.

Static Safety: Ensure all mixing equipment is properly grounded to prevent static discharge during transfer.

Storage: Store in a cool, dry place. Keep containers tightly sealed to prevent moisture absorption.

Packaging & Shelf Life:

Packaging: Typically available in 25kg fiber drums.

Shelf Life: 24 months from the date of manufacture when stored in the original, unopened container under recommended conditions.
