The fatty alcohol polyoxyethylene ether series surfactants have many varieties due to the difference in the number of carbon atoms of the aliphatic alcohol and the number of ethylene oxide additions. The product of lower alcohol C7~9 and 5 mol ~ 6 mol EO (trade name: penetrant JFC) has good wetting and permeability properties and is applied to various processing of fibers.
When the fatty alcohol has a carbon number of C12~14, it is usually used as AEO; AEO2~3 is insoluble in water, and is usually used as a raw material for synthesizing high-efficiency detergents such as AES, AEC and AESS, and has emulsification and leveling. And infiltration and other properties, can be used as a leveling agent, wetting agent and various oil components in the textile industry; AEO4~9 is an oil-soluble emulsifier, mainly used in wool detergent, wool spinning industry degreaser, fabric net The active ingredients of lotions and liquid detergents are generally used as emulsifiers in the industry; AEO7, AEO9 and AEO10 have good wetting, emulsifying and decontaminating properties, are used as active ingredients in detergents, detergents and wetting in the textile industry. AEO15 and AEO20 have good emulsification, dispersion and decontamination properties, used as leveling agent in textile industry, metal processing cleaning agent and emulsifier for cosmetics, pesticides and inks. When the fatty alcohol has a carbon number of C14~18, it is usually called flat addition. Among them, C14~16 is called flat plus OS; C16~17 is called flat plus O, and C18 is called flat plus A. This series has good emulsification and dispersion properties. The ethoxylate of secondary alcohol has good biodegradability, low viscosity, high solubility, narrow gelation range and good resistance to hard water, good wetting force and detergency; good foam breaking and easy rinsing; Low irritation and easy to mix with other substances. It can be used as detergents, emulsifiers, wetting agents, dispersants and plasticizers in the fields of detergents, chemical specialties, plastics, leather and textiles.
