A higher secondary alcohol alkoxylate compound composition represented by the general formula (1):[wherein R1 and R2 represent an alkyl group provided that the total number of carbon atoms of R1 and R2 is in the range of 7 to 29 and the number of carbon atom of R2 is not less than that of R1 (the number of carbon atom of R1<the number of carbon atom of R2), A represents a lower alkylene group, n represents a numeral in the range of 1 to 50 on the average; providing that when n is not less than 2, the number of species of oxyalkylene group represented by AO may be either one or two or more, and that when the oxyalkyl groups have two or more species, all the oxyalkylene groups are present in the average of n, and B represents a hydrogen atom or SO3M (wherein M represents an alkali metal atom, an alkaline earth metal atom, an ammonium group or a substituted ammonium group)], wherein the composition comprises 30 to 90 mol % of the higher secondary alcohol alkoxylate compound (X) having a methyl group for R1 and 70 to 10 mol % of the higher secondary alcohol alkoxylate compound (Y) having an alkyl group of 2 or more carbon atoms for R1, a method for the production thereof, and a detergent and an emulsifier using the composition.
