The antiseptic fungicide contains a 1,2-alkanediol represented by formula (1): R1-CH(OH)-CH2-OH (wherein R1 is a 3 to 8C alkyl group) and a glyceryl ether derivative represented by formula (2): R2-O-CH2-CH(OH)-CH2-OH (wherein R2 is a straight chain or branched 3 to 14C alkyl group). The cosmetic, medicine, and the food compounded with the same are also provided. Desirably, the 1,2-alkanediol is 1,2-hexanediol or 1,2-octanediol, and more desirably, it is 1,2-octanediol.
