Property and application
It is a kind of anionic surfactant with excellent performance. It has good cleaning, emulsifying, wetting, densifying and foaming performance, with good solvency, wide compatibility, strong resistance to hard water, high biodegradation, and low irritation to skin and eye. It is widely used in liquid detegent, such as dishware, shampoo, bubble bath and hand cleaner, ect. Aes can also be used in washing powder and detergent for heavy dirty. Using aes to replace las, phosphate can be saved or reduced, and general dosage of active matter is reduced. In textile, printing and dyeing, oil and leather industries, dyeing agent, cleaner, foaming agent and degreasing agent.
