Abstract
The present invention is directed to detergent compositions that not only have superior viscosity, spreadability, and clarity properties but also do not cause significant irritation to the skin and eyes. More specifically, acrylic polymeric thickeners are combined with polyol glycol thickeners in order to achieve such properties in detergent compositions.
Claims29
A detergent composition comprising:
- a) a hydrophobically modified acrylic copolymer thickener;
- b) a polyol alkoxy ester thickener;
- and
- c) at least one surfactant selected from the group consisting of an anionic surfactant, a non-ionic surfactant, an amphoteric surfactant, a betaine surfactant, and mixtures thereof, wherein the composition contains greater than about 1%, based upon the total weight of the composition, of the polyol alkoxy ester thickener and
- wherein the polyol alkoxy ester is selected from:
- a) a polyethylene glycol ether of a monoester of methyl glucose and an alkyl acid having from about 10 carbon atoms to about 24 carbon atoms and having an average of between about 75 and 150 moles of ethylene oxide;
- b) a polyethylene glycol ether of a diester of methyl glucose and an alkyl acid having from about 10 carbon atoms to about 24 carbon atoms and having an average of between about 75 and 150 moles of ethylene oxide;
