Higher secondary alcohol alkoxylate precursor, higher secondary alcohol alkoxylate adduct, higher secondary alkyl ether sulfate ester salt, and method for preparing the same

摘要

[Problem] An object of the present invention is that when used as a surfactant, it has excellent cleaning power, has no odor, and is free from high-grade secondary alcohol alkoxylate adducts and odors without cloudiness or separation. It is to provide a higher grade secondary alkyl ether sulfate ester salt having skin irritation. Furthermore, it is providing the manufacturing method of the said higher secondary alcohol polyalkoxylate and a higher secondary alkyl ether sulfuric ester salt. [Solutions] A precursor of a higher secondary alcohol alkoxylate obtained by reacting a long-chain olefin with (poly)alkylene glycol, with respect to the total mass of the higher secondary alcohol alkoxylate (poly)alkyl A higher secondary alcohol alkoxylate precursor having a content of renglycol of 0.2% by mass or less, a higher secondary alcohol alkoxylate adduct which is an alkylene oxide adduct of the higher secondary alcohol alkoxylate precursor, and the higher secondary It is solved by a higher secondary alkyl ether sulfuric ester salt which is a sulfur oxide of a primary alcohol alkoxylate precursor or a higher secondary alcohol alkoxylate adduct.
