Abstract
Abstract A detergent composition is disclosed, which comprises the components (A) and (B): (A) a secondary amide type N-acylamino acid salt represented by formula (1): R.sup.1 CONH(CH.sub.2).sub.n COOM.sup.1 (1) wherein R 1 CO represents a straight chain acyl group having 10 to 16 carbon atoms; n is an integer of 1 or 2; and M 1 represents a sodium or potassium atom or an alkanolammonium group when n is 1, or a potassium atom or an alkanolammonium group when n is 2; and (B) a germicide selected from the group consisting of triclosan, trichlorocarbanilide, isopropylmethylphenol and chlorhexidine hydrochloride. This detergent composition shows a high detergency, gives a good feel upon use, causes little irritation to skin and causes little damage to hair. Further, it exerts a good germicidal effect which can last for a prolonged period of time. It is particularly suitable for cleansing the skin.
