Patent ID: 7138365

Claim:
A liquid detergent composition comprising A) a thickening agent comprising at least one hydroxyalkyl polyhydric alcohol ether compound of formula (1) or (2) wherein R 1 is an alkyl or alkenyl group having 8 to 18 carbon atoms, R 2 , R 3 , R 4 and R 5 are, independently from each other, a hydrogen atom or an alkyl group having 1 to 3 carbon atoms, and n is an integer of 0 to 3 and B) a liquid detergent component comprising at least one of (a), (b), (c) or (d): (a) an acetic acid betaine amphoteric surfactant of formula (14): wherein r is an integer of 0 or 1, R 18 is an alkyl or alkenyl group having 10 to 18 carbon atoms when r is 0, or a fatty acid residue having 10 to 18 carbon atoms when r is 1, R 19 and R 20 are, independently from each other, a hydrogen atom or a methyl or ethyl group, and s is an integer of 2 or 3; (b) an amidoamine amphoteric surfactant of formula (5): wherein R 6 —CO is a residue group of an aliphatic acid having 10 to 18 carbon atoms, s is an integer of 2 or 3, and M 1 is an alkali metal atom or an alkanolamine residue group, and v and w are, independently of each other, an integer of 1 to 3, (c) a sulfo betaine dipolar-ionic surfactant of formula (13): wherein r is an integer of 0 or 1, R 15 is an alkyl or alkenyl group having 10 to 18 carbon atoms when r is 0, or a fatty acid residue having 10 to 18 carbon atoms when r is 1, R 16 and R 17 are, independently from each other, a hydrogen atom or a methyl or ethyl group, and s is an integer of 2 or 3; or (d) a semipolar-ionic surfactant of formula (16): wherein r is an integer of 0 or 1, R 22 is an alkyl or alkenyl group having 10 to 18 carbon atoms when r is 0, or a fatty acid residue having 10 to 18 carbon atoms when r is 1, R 23 and R 24 are, independently from each other, a hydrogen atom or a methyl or ethyl group, and s is an integer of 2 or 3.
