Function
Fatty alcohol polyoxyethylene ether is widely used in the production of fatty alcohol polyoxyethylene ether sodium sulfate (AES). The physical properties of fatty alcohol polyoxyethylene ether make it unfavorable for formulation into laundry detergent, but it is an ideal raw material for liquid detergents. It has better descaling ability than sodium alkylbenzenesulfonate on various fibers, especially suitable for washing away oil and dirt excreted by the human body from synthetic fiber fabrics. This product has unique emulsifying properties for stearic acid, paraffin, mineral oil, etc. It is a component of emulsifier in polymer lotion polymerization. It can also be used as an emulsifier for glass fiber lubricating oil. This product can remove the dirt caused by dye dispersion and aggregation on fabrics, improve the cleaning ability of sodium alkylbenzenesulfonate synthetic detergents, and reduce the anti-static effect of fabrics.
Application
1. Washing industry: As a non-ionic surfactant, it has emulsifying, foaming, and cleaning effects, and is the main active ingredient in hand sanitizer, laundry detergent, shower gel, laundry detergent, dishwashing detergent, and metal cleaning agents.
Packing
