Abstract

The invention discloses a composite thickening agent-type alcohol ether sulfate surfactant. The surfactant comprises alcohol ether sulfate, PEG and fatty acid monoethanolamide and / or fatty acid diethanolamide. The composite thickening agent-type alcohol ether sulfate surfactant has good dissolution dispersibility in water, improves high and low temperature stability of the subsequent formulation viscosity, especially improves the low temperature stability, solves the problem that the alcohol ether sulfate easily produces gel in a cooling preparation technology and fatty acid monoethanolamide is not easy to dissolve, can be widely used in a detergent, shampoo and shower gel, and has synergistic thickening and foam stabilization effects. A thickening agent mass ratio is flexibly adjusted in a certain range according to downstream application needs, different customer needs are satisfied, a feeding process is avoided, energy consumption is reduced and the use by downstream customers is convenient.

Description

[0001] field of invention [0002] The invention relates to a compound thickener type alcohol ether sulfate surfactant, in particular to a surfactant composed of alcohol ether sulfate, PEG and fatty acid monoethanolamide and / or fatty acid diethanolamide, which has stable thickening effect and surface active agent. The active action composition belongs to the fine chemical industry field. Background technique [0003] The molecular structure of alcohol ether sulfate has oxyethylene groups and sulfated groups, and has the properties of non-ionic and anionic surfactants, such as strong wetting, dispersing, detergency of emulsifiers, and very good resistance to hard water Non-toxic and biodegradable, it is widely used in laundry detergent, detergent, personal cleaning products (shampoo, hand sanitizer, body wash) and other fields. However, AES also has some defects, such as poor grease removal ability and poor fluidity, and it is easy to produce gel when dissolved in water, which...
