    • PURPOSE:To provide a liquid cosmetic having a transparency higher than a specific level and exhibiting sufficiently high antiseptic mildew-proofing effect. CONSTITUTION:This liquid cosmetic is produced by compounding (A) one or more kinds of an N-(long-chain acyl) basic amino acid derivative of the formula I or the formula II (RCO is 6-20C saturated or unsaturated fatty acid residue; X is NH2, OCH3, OC2H5, OC3H7, OC4H9 or OCH2C6H5; (n) is 3 or 4), e.g. N- cocoyl-L-arginine ethyl ester PL-pyrrolidonecarboxylic acid salt with (B) 2- phenoxyethanol. The amount of the component A is 0.001-0.5wt.%, preferably 0.005-0.1wt.% and that of the component B is 0.1-1.0wt.%. The combination of both components is stable in the liquid cosmetic, free from undesirable effect on the safety of the cosmetic itself and resistant to the crystal deposition and clouding even by leaving standing at a low temperature. It exhibits strong inhibiting effect on general microorganisms and sufficient effect at a small amount compared with the separate use of the individual component.
