Because silicone surfactants have many advantages, such as non-toxicity, no skin irritation, anti-oxidation, ultraviolet protection, good biocompatibility, excellent waterproof and breathable properties, they are used in cosmetics, shampoo products, creams Some silicone products and touch keypad membrane products have a certain degree of application. Because of its low surface tension and suitable viscosity, silicone surfactants are beneficial to the diffusion of cosmetics on the skin and hair surface, can improve the moisturizing and retention of cosmetics on the skin, and can maintain the normal breathability of the skin, and can also give Hair shine, easy to comb, smooth and neat, anti-static and soft.
Silicone surfactants have antistatic properties, softness, and good sterilization and disinfection capabilities, and can give fibers a good softening effect. Cationic silicone surfactants are mainly used as antistatic agents and softeners in the textile industry. Quaternary ammonium salt cationic silicone surfactants are used for the sanitary finishing of fiber products and have good sterilization and mildew resistance. And safe and durable.
In pesticide processing, the addition of 0.05%-0.1% (mass fraction) of silicone surfactant as an auxiliary agent can optimize the physical properties and chemical stability of the formulation, increase the variety of formulations and expand the scope of application. Plant leaf and stem epidermis often have anti-wetting ingredients or structures, and often have a negative charge, which has a repelling effect on pesticide liquids, and the addition of silicone surfactants can promote the smooth attachment of pesticide formulations on plants. Retention, spreading and penetration play a key role in improving the efficacy of the medicine. Silicone surfactants can reduce their surface tension and allow water to penetrate into the trachea of insects to make them lethal. They act as pesticide adjuvants.
Organosilicon defoamer is made up of modified polysiloxane as the main ingredient, adding a variety of non-ionic surfactants, etc. It has excellent defoaming performance, low dosage, easy to use, non-toxic, no It is corrosive and has good defoaming and anti-foaming effects on MSG, soy products, and foams produced in the production of antibiotics.
The silicone surfactant can be mainly used as a fatliquor and softener in leather because it has good lubricating properties and waterproof properties. The organosilicon fatliquor prepared by graft copolymerization with grease solves the problem that the silicon-containing surfactant is easy to migrate outward, reduces the amount of fatliquor, and reduces the cost. Leather fibers impregnated with silicone surfactants have good dispersion and lubricating properties, and the finished leather is soft, especially suitable for clothing leather and shoe upper leather, and can also be used for fur manufacturing. Amino polyether co-modified silicone surfactants are used as fatliquoring agents to achieve a satisfactory degree of softness and hydrophilicity. In addition, they can also be used as finishing agents, water repellents, and enzyme preparations to soften the leather. Bright and oily. 6. Application in mechanical processing In the production, use and maintenance of metal products, it is necessary to clean all kinds of dirt attached to its surface (such as metal shavings, cutting fluid, abrasives and various greases, dust during processing And electrolytes such as acids, alkalis, salts, and hand sweats, etc.) to ensure the internal and surface quality of the product and extend the service life. The silicone surfactant cleaning agent has good cleaning performance and strong detergency. It can not only remove oil stains on the metal surface but also clean hand sweat, inorganic salts, and other dirt. In addition, it is non-flammable, non-toxic, and safe to use. And good corrosion and corrosion resistance, it can also save energy and reduce environmental pollution, suitable for mechanized automatic cleaning.
Silicone surfactant plays an important role in the production process of polyurethane foam, such as system dispersion, bubble growth, bubble stabilization, and air chamber opening. It is a good foam stabilizer for polyurethane foam. Using its surface activity, it can produce polyurethane soft foam, hard foam, semi-rigid foam, and high resilience foam. In addition, the use of flame retardant silicone foam stabilizers in polyurethane foam is becoming more and more widespread.
