In the fields of daily chemicals and textile light industry, the softness, smoothness, water resistance, and skin-friendliness of materials directly determine the user experience. With excellent adhesion and film-forming ability brought by reactive hydroxyl groups, as well as the smooth and soft characteristics of polysiloxane itself, hydroxyl silicone oil has become a core additive in textile finishing, daily chemical care, and leather processing, reshaping the touch and functions of various daily materials with its mild, efficient, and long-lasting advantages.
In the textile industry, hydroxyl silicone oil is an important raw material for high-end fabric softening and waterproof finishing. Compared with ordinary silicone oil, hydroxyl groups can form hydrogen bonds with hydroxyl and amide groups on the surface of cotton, linen, silk, chemical fiber and other fabrics, resulting in firmer adsorption, less shedding, and significantly improved washing resistance. Fabrics finished with it are soft, fluffy, smooth and non-greasy, while maintaining good air permeability without stuffiness. Terminal hydroxyl silicone oil is often compounded with hydrogen-containing silicone oil for fabric water-repellent finishing, forming a uniform and continuous hydrophobic film on the fiber surface, with a waterproof grade reaching the high national standard level, without affecting the handle and color of the fabric. It is widely used in outdoor clothing, home textiles, and sports fabrics. In addition, hydroxyl silicone oil can improve the antistatic property of fabrics, reduce friction pilling, enhance the tearing strength and wear resistance of fabrics, and extend the service life of clothing.
The daily chemical field is an important application scenario of hydroxyl silicone oil, with its core value lying in balancing skin feel and efficacy. In hair care products, hydroxyl silicone oil can adsorb on the surface of hair scales, fill damaged gaps, close hair scales, reduce hair frizz and split ends, improve wet and dry combing performance, and endow hair with natural luster without greasiness or flattening. In skin care products, body washes, and hand creams, hydroxyl silicone oil can reduce the surface tension of products, improve spreading performance, bring a refreshing and silky skin feel, reduce sticky residues, and form a thin and breathable protective film on the skin surface to reduce water loss and achieve moisturizing effects. Due to its physiological inertness, mildness and non-irritation, it is also suitable for infant care products and sensitive skin care formulas.
In leather processing, hydroxyl silicone oil acts as a "leather beautician". Adding hydroxyl silicone oil during leather tanning and finishing can improve the softness and fullness of leather, enhance the smoothness and gloss of the leather surface, make the leather feel delicate, resistant to creases and aging, and enhance the water and stain resistance of leather. Hydroxyl silicone oil has good compatibility with leather fibers, penetrates evenly, does not cause hardening or discoloration of the leather surface, and can retain the natural texture of leather to the greatest extent. It is widely used in the production and care of genuine leather sofas, leather shoes, and leather goods.
With consumption upgrading, people's requirements for daily products have shifted from "usable" to "easy to use, skin-friendly, and environmentally friendly". With the characteristics of green safety, long-lasting effect, and strong adaptability, hydroxyl silicone oil continues to penetrate the high-end daily chemical and textile markets, becoming a key additive to enhance product added value and build core competitiveness, promoting the development of the light industry towards high-quality and refined direction.
