[Problem] An object of the present invention is to provide a higher secondary alcohol alkoxylate adduct having excellent detergency, generating no odors and generating no white turbidness or no separated substances when used as a surfactant, and a higher secondary alkyl ether sulfate ester salt generating no odors and having low skin irritancy when used as a surfactant. Another object is further to provide a method for producing the higher secondary alcohol polyalkoxylate and a method for producing the higher secondary alkyl ether sulfate ester salt.[Solution] Solution to problem is: a higher secondary alcohol alkoxylate precursor obtained by reacting a long-chain olefin with a (poly)alkylene glycol, wherein the precursor has a content of (poly)alkylene glycol of 0.2% by mass or lower with respect to the total mass of the higher secondary alcohol alkoxylate; a higher secondary alcohol alkoxylate adduct which is an alkylene oxide adduct of the higher secondary alcohol alkoxylate precursor; and a higher secondary alkyl ether sulfate ester salt which is a sulfated product of the higher secondary alcohol alkoxylate precursor or the higher secondary alcohol alkoxylate adduct.
