Description

3-Hydroxypropylmethylsiloxane, Ethoxylated is a specialized organosilicon compound, a polyether-modified siloxane that combines the unique properties of silicone with the hydrophilic character of polyethers. This dual functionality makes it an exceptionally versatile and effective surfactant, emulsifier, and foam control agent for demanding industrial formulations. It is a critical raw material for manufacturers in the personal care, coatings, textile, and agrochemical industries seeking to enhance product performance, stability, and processability.

Application

• Personal Care & Cosmetics: Acts as a high-performance emulsifier, solubilizer, and conditioning agent in creams, lotions, shampoos, and color cosmetics, providing a smooth, non-greasy feel and improved product stability.
• Polyurethane Foam Production: Serves as a key silicone surfactant for stabilizing foam cell structure in flexible, rigid, and molded polyurethane foams, ensuring uniform cell size and optimal physical properties.
• Coatings & Inks: Functions as a flow and leveling agent, wetting agent, and defoamer in water-based and solvent-based coating systems, improving substrate wetting and reducing surface defects.
• Agrochemical Formulations: Used as a spray adjuvant, wetting agent, and emulsifier in pesticide and herbicide concentrates, enhancing droplet spread, adhesion, and overall efficacy on plant surfaces.
• Textile & Fiber Processing: Employed as a softener, lubricant, and anti-static agent for synthetic and natural fibers, improving handle, sewability, and processing performance.
• Industrial Cleaning: Acts as a surfactant and defoamer in industrial and institutional cleaning products, providing effective cleaning with controlled foam.
