Sodium lauryl ether sulfate (SLES), also called AES or sodium laureth sulfate, is the white or light yellow viscous paste in appearance. It is an anionic surfactant, easily soluble in water. It has excellent decontamination, emulsifying, wetting, dispersing, thickening and foaming properties, and at the same time, sodium laureth sulfate is also a good emulsifier. SLES 70% can be used in combination with other anionic, nonionic or amphoteric surfactants. However, due to its anionic character, the sodium lauryl ether sulfate 70 should not be used with cationic components such as cationic surfactants, cationic dyes.

SLES chemical has broad compatibility, good resistance to hard water and high biodegradability, and it has low skin and eye irritation. Therefore, as an anionic detergent and surfactant, sodium lauryl ether sulphate (SLES 70) is widely found in many personal care products, such as soaps, shampoos, and toothpastes. Sodium laureth sulfate (SLES) can be used in wetting formulations, liquid detergents, cleansers, shampoos and laundry detergents. In addition, SLES is also used in many cosmetic products with cleansing and emulsifying properties.
