PROBLEM TO BE SOLVED: To provide a method for preparing a monoglyceride sulfate, scarcely forming by-products, such as inorganic salts including sodium sulfate, capable of conducting reaction without using solvents, having few restrictions on reactor, and therefore capable of preparing the product at a low cost. SOLUTION: This method for preparing the monoglyceride sulfate comprises reacting an acetal compound of monoglyceride or a ketal compound thereof expressed by general formula (1) (R1 is a residue formed by removing carboxy group from a 6-22C saturated or unsaturated fatty acid; R2 and R3 are each H, a 1-8C straight-chain alkyl, a 1-8C branched-chain alkyl or the like; X is H or-SO3M; and M is a cation) with a sulfating agent to form the monoglyceride sulfate compound of general formula (2).
