Introduction of fatty alcohol polyoxyethylene ether
[Summary Description] Fatty alcohol polyoxyethylene ether (AEO), also known as polyoxyethylene fatty alcohol ether. The development of short and long ionic surfactants is very fast and the amount is very large. This type of surfactant is an ether formed by the condensation of polyethylene glycol (PEG) and fatty alcohol, which is revealed by the following general formula: RO(CH2CH2O)nH, where n is the degree of polymerization, due to the degree of polymerization of polyethylene glycol and the variety of fatty alcohol. The trade name is Benzyl (Brij), such as Brij30 and Brij is a difference in the number of polyethylene glycol and lauric acid polycondensation, can be used as O/W type emulsifier.

The number of ethoxy groups in fatty alcohol polyoxyethylene ether molecules can be adjusted in the process of synthesis, so a series of nonionic surfactants with different properties and uses can be prepared. A class of non-ionic surfactants that are short and long of fatty alcohol polyoxyethylene ethers. The ether bond in the molecule is not easy to be destroyed by acid and alkali, so it has high consolidation, good water solubility, electrolyte resistance, easy biodegradation and small foam. In addition to a large number of applications in the textile printing and dyeing industry, but also a large number of low foam liquid detergent compound. The fatty alcohol polyoxyethylene ether has good compatibility with other surfactants. Not sensitive to hard water, low temperature washing performance is good, but with the increase of water temperature, the ablation degree will gradually decrease. In the limit of pH 3~11, fatty alcohol polyoxyethylene ether hydrolysis consolidation. However, they also oxidize slowly in the atmosphere, with a small amount of oxidation products, such as acetaldehyde and hydroperoxides, which are more toxic to the skin than surfactants that have not yet undergone a similar environment.
