化学的特性
Sodium isethionate is a colorless, syrupy, strongly acidic liquid that can form detergents with oleic acid. It is an organic salt and an important intermediate for pharmaceuticals, cosmetics and daily chemicals.
使用
Isethionic acid sodium salt is an amphoteric detergent used in detergent bar soaps. It makes a dense lather in addition to the lather made by the soap. It is mild on the skin, and non-drying. It works equally well in soft or hard water. It is also an anti-static agent in shampoos.
製造方法
Sodium isethionate is synthesized by the condensation reaction of sodium bisulfite and ethylene oxide.
主な応用
Sodium Isethionate works as an amphoteric detergent and can also be used as an intermediate in preparing surfactants derived from fatty acid sulfoalkyl esters (acyloxy ethane sulfonate). Sodium Isethionate increases the formulation's stability, improves the detergency in hard water, and is smooth to the skin. It is used in cleaning/washing agents, disinfectants, cosmetics, surface-active agents, shampoos, and bubble baths.
