Abstract
A thickened composition having a complex viscosity at 1.58 Hz of about 0.1 to about 200 Pascal seconds, a G' value of about 0.1 to about 1500 dynes/sq cm over a strain range of 1 to 5% and a G" value of about 0.1 to about 1000 dynes/sq cm over a strain range of 1 to 5% which comprises approximately by weight 2 to 25 wt % of a nonionic surfactant having an HLB of about 0.1 to about 8.0; 0.1 to 10.0 wt % of a polymeric thickener; 2 to 30 wt % of an aliphatic hydrocarbon having about 6 to about 22 carbon atoms; and the balance being water.

A thickened composition having a complex viscosity at 25 C. at 1.58 Hz of about 0.1 to about 200 Pascal seconds, an elastic modulus G' value of about 0.1 to about 1500 dynes/sq cm over a strain range of 1 to 5% and a viscous modulus G" value of about 0.1 to about 1000 dynes/sq cm over a strain range of 1 to 5% which comprises approximately by weight:
- (a) 2 to 25% of a nonionic surfactant having an HLB of about 0.1 to about 8.0;
- (b) 0.1 to 10.0% of an associative polymeric thickener which is a polymer which is the reaction product of an alkylene oxide copolymer having a molar mass of about 5000 to 50,000 and having an OH functionality at each end of the polymer chain and two alkyl chain epoxides, each of which has about 12 to about 24 carbon atoms;
- (c) 2 to 30% of an aliphatic hydrocarbon having about 6 to about 22 carbon atoms;
- and
- (d) the balance being water.
