A novel phosphobetaine is disclosed. This compound is very excellence in that it exerts a conditioning effect of imparting a good feel to the skin or hair, is excellent in humidifying properties, is available at a low price, and thus it is highly usable in detergents, cosmetics, a bathing preparation and the like. A detergent composition, a cosmetic, and a bathing preparation each containing the phosphobetaine are also disclosed.

Phosphoric acid esters represented by the following formulae (I) and (IX) as well as processes for preparing them are disclosed. ##STR1## wherein R.sub.1 represents a linear or branched, alkyl or alkenyl group having a C.sub.1-36 carbon atom content, with or without the hydrogen atom(s) being substituted with fluorine atom(s), or a phenyl group with substituted linear or branched alkyl group(s) having a C.sub.1-15 carbon atom content, R.sub.2 represents an alkylene group having a C.sub.2-3 carbon atom content, R.sub.3 and R.sub.4 independently denote a hydrogen atom or an alkyl group having a C.sub.1-3 carbon atom content, R.sub.5 and R.sub.6 independently denote a hydrogen atom, or an alkyl, alkenyl, or phenyl group with or without the hydrogen atom(s) being substituted with group(s) containing hetero atom(s), excepting for a mercapto group, R.sub.7 and R.sub.8 independently denote a hydrogen atom, or an alkyl, or alkenyl group, m is an integer of 0-30, n is an integer of 0-5, l is an integer of 0-3, M is a hydrogen atom, an alkali metal, an alkali earth metal, an ammonium group, an alkyl amine group, or an alkanol amine group. The phosphoric acid esters have outstanding surface activity and good foaming capability, and imparts only extremely low irritation to the skin. The detergent composition into which they are formulated is particularly useful as, shampoo, baby shampoo, body shampoo.
