Phosphate surfactant based detergent compositions

Claim 1

A detergent composition, the major active detergent component of which consists of: (A) 10-40 weight % of at least one phosphate surfactant selected from the group consisting of compounds of formulas (I) and (II): ##STR10## wherein R 1 , R 2 and R 3 each independently represent a saturated or unsaturated hydrocarbon group having 8 to 18 carbon atoms; X and Y each independently represent a hydrogen atom, an alkali metal, ammonium, or an alkanol amine having at least one hydroxyalkyl group having 2 to 3 carbon atoms; and l, m and n each independently represent an integer of 0 to 10, and (B) a compound selected from the group consisting of the following compounds (1) to (3): (1) an amidoamine amphoteric surfactant of formula (III) or (IV): ##STR11## in which R 4 and R 5 each independently represent a saturated or unsaturated hydrocarbon group having 7 to 19 carbon atoms; M represents a hydrogen atom, an alkali metal, ammonium, or an alkanol amine having at least one hydroxyalkyl group having 2 to 3 carbon atoms, wherein said amidoamine amphoteric surfactant (B)-(1) is present in at least one part to less than 20 parts by weight based on 20 parts of said component (A), (2) 0.1-20 weight % of a hydroxysulfobetaine of formula (V): ##STR12## wherein R 6 represents a saturated or unsaturated hydrocarbon group having 8 to 18 carbon atoms, and R 7 and R 8 each independently represent a methyl or ethyl group, and (3) 0.1-5 weight % of a compound of formula (VI) and its salt: ##STR13## wherein RCO represents a linear or branched aliphatic acyl group having 6 to 22 carbon atoms; A represents CH 3 or a hydrogen atom, and p represents an integer of 1 to 3.
