In the world of the cosmetics industry, surfactants with a wide variety of properties and different properties are playing an increasingly important role. The 21st century cosmetics industry will fully integrate the high-tech achievements of various contemporary disciplines, and the variety, performance and safety of products will be further improved.
At present, the theoretical research on the rheological properties of cosmetics and the relationship between sensory evaluations in the domestic cosmetics industry and even large international research institutions is still insufficient. The selection and use of both surfactants and surfactants are also in the primary application stage. Therefore, it is a major hot issue in the cosmetics industry to vigorously develop raw materials such as surfactants with excellent performance and safe use and actively carry out relevant basic theoretical research.
Certain nonionic emulsifiers are the primary surfactants used in the cosmetic industry. As an emulsifier for formulating skin care lotions, alkyl polyglycosides must have good compatibility and compatibility. In order to meet the requirements of safety, viscosity, drainage, etc., the polyether-modified silicone-containing silicone surfactant is an emulsifier alkyl phosphate ester, amino acid surfactant, commonly used in the preparation of silicone oil emulsion. A fatty acid ester derivative of a glucoside and a sucrose ester alkyl polyglycoside polyglycerol fatty acid are also commonly used emulsifiers.
In the cosmetics industry, solubilizers are mainly used in the production of products such as lotions, hair oils, and hair growth conditioners. Since the oily components in cosmetics differ in structure and polarity, the mechanism of their dissolution is also different. Polyoxyethylene hardened castor oil, polyoxyethylene castor oil, polyoxyethylene sorbitan, polyglycerol fatty acid ester and other nonionic surfactants and castor oil-based amphoteric derivatives can achieve better hydrolytic effect. When the lotion of the lotion is a fragrance, it should be dissolved with alkyl polyoxyethylene ether. Other surfactants used as solubilizers are required to be highly hydrophilic. In addition, the solubilizer should be non-irritating to eyes, skin, and the like.
The phenomenon in which a water-insoluble substance forms fine particles in water and is uniformly dispersed is called dispersion. Most of the surfactants used as dispersants are also emulsifiers, such as fatty alcohol ethoxylates, which have good dispersing properties. In addition, amphoteric surfactants are widely used in the manufacture of cosmetics due to their good detergency, biodegradability, mildness, low toxicity and low irritation, and have a good dispersing effect.
