Description

Dimethicone Copolyol is a versatile organosilicone surfactant that combines the hydrophobic properties of polydimethylsiloxane with the hydrophilic nature of polyoxyalkylene groups. This unique structure makes it an exceptional wetting agent, emulsifier, and foam stabilizer for challenging formulations. It is essential for manufacturers in the personal care, cosmetics, and industrial sectors seeking to improve product performance and stability.

Application

• Personal Care & Cosmetics: Acts as a key emulsifier and stabilizer in water-in-silicone and oil-in-water emulsions for creams, lotions, and sunscreens.
• Hair Care Products: Used in conditioners, shampoos, and styling aids to provide excellent wet combing, shine, and reduced frizz without buildup.
• Antifoaming Agent: Employed in aqueous systems, including paints, coatings, and industrial processes, to control and suppress foam.
• Textile & Fiber Processing: Functions as a softener, lubricant, and anti-static agent to improve the handle and processing of synthetic fibers.
• Agricultural Adjuvants: Enhances the spreading and wetting of pesticides and herbicides on waxy leaf surfaces, improving efficacy.
• Industrial Cleaners & Polishes: Provides superior leveling, gloss, and water repellency in automotive and furniture polish formulations.

Quality Control

Our Dimethicone Copolyol is manufactured under a strict quality management system. Each batch is tested against rigorous in-house specifications to ensure consistent performance, purity, and safety for its intended applications. Certificates of Analysis (COA) documenting key parameters such as viscosity, cloud point, and non-volatile content are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent absorption of atmospheric moisture, which may affect product properties.
