Patent ID: 7504370

Claim:
A method for enhancing foamability which comprises adding(B) at least one glyceryl mono-alkyl ether having an alkyl group of 6 to 10 carbon atoms to a detergent composition for personal washing comprising (A) at least one phosphate ester or a salt thereof represented by the following formula (1): wherein R 1 represents a linear or branched hydrocarbon group having 11 to 18 carbon atoms, m stands for a number of from 0 to 3 on weight average, X represents a hydrogen atom, an alkali metal atom, ammonium, a basic amino acid residual group, or an alkanolamino group having a hydroxyalkyl group of 2 to 3 carbon atoms, and R 2 represents —(CH 2 CH 2 O) m —R 1 or X, or a mixture thereof, wherein foamability is at least 150 mL of foam from 100 mL of a 20-fold aqueous dilution of said detergent composition.
