Thickening method and thickening formula of fatty alcohol polyoxyethylene ether sodium sulfate

Abstract

The invention discloses a fatty alcohol polyoxyethylene ether sodium sulfate thickening method, which specifically comprises: 1, pre-preparing: adding ammonium acetate and cocoanut fatty acid diethanolamide to 40 parts of AES, heating to 40-50 DEG C, and stirring until complete dissolution to prepare a mixture; and step 2, adding the mixture pre-prepared in the step 1 into 960 parts of AES in batches, heating to 40-50 DEG C, and stirring until the mixture is uniformly stirred. The invention also discloses a thickening formula of fatty alcohol polyoxyethylene ether sodium sulfate. The thickening formula comprises the following components in parts by weight: 0.1-0.3 part of ammonium acetate, 0.7-1.2 parts of cocoanut fatty acid diethanolamide and 1000 parts of AES. Ammonium acetate is added into AES and is compounded with cocoanut fatty acid diethanolamide to increase viscosity, so that a relatively good thickening effect is achieved. The process is simple, industrial production is easy, the addition amount is small, the AES thickening effect is better, production equipment is not corroded, irritation to skin is avoided, the antibacterial and mildew-proof functions are achieved, and the input cost is low.

Description

A kind of thickening method and thickening formula of fatty alcohol polyoxyethylene ether sodium sulfate technical field The present invention relates to fatty alcohol polyoxyethylene ether sodium sulfate preparation technical field, particularly a kind of fatty alcohol polyoxyethylene Thickening method and thickening formula of sodium alkenyl ether sulfate. Background technique Fatty alcohol polyoxyethylene ether sodium sulfate (AES) is widely used in shampoo, bath liquid, dishwashing detergent, compound soap etc. Polyester cosmetic products, thickening AES can reduce its dosage and save costs for enterprises. At present, thickeners or non- Organic salts thicken AES. Li Yinghua and others studied the thickening of AES by sodium chloride, potassium chloride, ammonium chloride and ammonium sulfate, and concluded that When the AES concentration is less than 5%, the thickening effect of sodium chloride is the best, but the addition amount is also large (about 7-8%); Ji...

AI Technical Summary

Problems solved by technology

The current thickening method of AES has the high cost of using a single thickener, and the Cl produced by ionization of inorganic salts - , SO 4 2- It is corrosive to the production equipment and reduces the service life of the equipment. At the same time, the high content of inorganic salts is highly irritating to the skin, etc.
