A detergent composition comprising a phosphate-type surface active agent and an alkyl saccharide-type surface active agent is described. The phosphate-type surface active agent which can be used have the following formula (I) or (II), and the alkyl saccharide-type surface active agent have the following formula (III): ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, and R.sub.4 represent a linear or branched alkyl, alkenyl group, or alkyl phenyl groups of a C.sub.8-18 carbon atom content, X and Y represent a hydrogen atom, an alkali metal, an ammonium, or an alkanol amine having a hydroxyl alkyl group of a a C.sub.2-3 carbon atom content, R.sub.5 represents an alklene group of a C.sub.2-4 carbon atom content, G represents a reduced sugar of a C.sub.5-6 carbon atom content, and l, m, n, and p denote a value of 0 to 10. The detergent composition exhibits exceptionaly good detergent capability and foaming capability. In addition, it imparts less irritation to the hair and skin, less creaking feeling to the hair, and superior smooth and moistened feeling to the skin.
