Product Overview
Sodium Laureth Sulfate, commonly known as SLES or AES, belongs to ethoxylated alcohol ether sulfate anionic surfactant.
SLES is manufactured by sulfation and neutralization of ethoxylated lauryl alcohol. The introduction of ethoxy groups effectively reduces skin irritation. It can rapidly reduce surface tension, generate dense and persistent foam, and maintain stable cleaning performance in hard water environments. It is easy to thicken with inorganic salt and easy to compound with various auxiliary surfactants, becoming one of the most mainstream surfactant raw materials in daily chemical and industrial cleaning industries.
