Abstract
Detergent compositions each of which comprises (A) at least one phosphate ester or a salt thereof represented by the following formula (1): wherein R1 represents a C8-C18 hydrocarbon group, m stands for a number of from 0 to 10 on weight average, X represents H, an alkali metal atom, ammonium, a basic amino acid residual group, or an alkanolamino group having a hydroxy(C2-C3 alkyl) group, and R2 represents —(CH2CH2O)m—R1 or X, or a mixture thereof, and (B) at least one glyceryl ether having a C4-C12 alkyl or alkenyl group. These detergent compositions are low in skin irritation and are good in foaming performance.
Claims9
A detergent composition comprising:
- (A) from 10 to 60 wt. % of at least one phosphate ester or a salt thereof represented by the following formula (1):
- where R1 represents a linear or branched hydrocarbon group having 8 to 18 carbon atoms, m stands for a number of from 0 to 10 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 R2 represents —(CH2—CH2O)m—R1 or X, or a mixture thereof, and
- (B) at least one glyceryl ether having an alkyl or alkenyl group of 4 to 12 carbon atoms.
A method for enhancing foamability which comprises adding at least one glyceryl ether having an alkyl or alkenyl group of 4 to 12 carbon atoms to a detergent composition comprising from 10 to 60 wt. % of at least one phosphate ester or a salt thereof represented by the following formula (1):
- where R1 represents a linear or branched hydrocarbon group having 8 to 18 carbon atoms, m stands for a number of from 0 to 10 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 R2 represents —(CH2—CH2O)m—R1 or X, or a mixture thereof.
A method for washing a person which comprises applying to a person a detergent composition comprising:
- (A) from 10 to 60 wt. % of at least one phosphate ester or a salt thereof represented by the following formula (1):
- where R1 represents a linear or branched hydrocarbon group having 8 to 18 carbon atoms, m stands for a number of from 0 to 10 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 R2 represents —CH2—CH2O)m—R1 or X, or a mixture thereof and
- (B) at leas one glyceryl ether having an alkyl or alkenyl group of 4 to 12 carbon atoms.
