Abstract
The present invention relates to a liquid detergent composition containing (a) a specific compound having one alkyl group selected from a 2-ethylhexyl group, an isononyl group and an isodecyl group, (b) a surfactant selected from anionic surfactants and amphoteric surfactants, (c) a hydrophobic organic solvent that is liquid at 20° C., and (d) water in specific ratios.
Claims18
A liquid detergent composition comprising:
- (a) at least one compound selected from the group consisting of a compound (a1) and a compound (a2), wherein the compound (a1) is a polyoxyalkylene alkyl ether having one alkyl group selected from the group consisting of a 2-ethylhexyl group, an isononyl group and an isodecyl group, wherein an average added mole number of alkylene oxides having 2 or 3 carbon atoms is 2 to 6, and wherein the compound (a2) is a compound represented by formula (I)
- wherein R1 is an alkyl group selected from the group consisting of a 2-ethylhexyl, an isodecyl, and an isononyl group,
- (b) at least one surfactant selected from the group consisting of an anionic surfactant and an amphoteric surfactant,
- (c) a hydrophobic organic solvent that is liquid at 20° C., has a solubility parameter of 10.0 to 21.0 and a solubility in water at 20° C. of 0.5% by mass or less,
- (d) water,
- (f) a glycol solvent, and
- (e) optionally, one or more surfactants other than component (a) and component (b),
- wherein
- [(a)+(b)]/(c) (mass ratio) is 1.75 or less,
- (b)/(a) (mass ratio) is 0.1 or more,
- (a)/(c) (mass ratio) is 0.7 or more, and
- [(a)+(b)]/the total surfactants (mass ratio) is 0.95 to 1, and
- wherein the total surfactants is the sum of (a)+(b)+(e).
