PURPOSE:To stop various functions as a surface active agent quickly after surface activity is developed in manufacturing coating materials or the like by preparing a sulfate-type anionic surface active agent having an allyl group shown by a specific formula. CONSTITUTION:Allyl glycidyl ether, with lauric acid or oleic acid as raw material, is heated up and reacted in the presence of a catalyst, and alkylene oxide is added to a reaction composition thus prepared by the conventional procedure. Then, the same is sulfated with a sulfating agent such as sulfuric acid or the like, and, if necessary, neutralized with a basic substance to prepare a surface active agent. Said surface active agent is a compound shown by formula I [R shows a 6-30C aliphatic acid residue, (A) shows a 2-4C alkylene or substituted alkylene group, n shows an integer of 0-100, m shows an integer of 1-200, M shows alkali metal, NH4 or alkanolamine residue].
