Abstract
A thickened composition having a complex viscosity at 25.degree. C. and at 1.58 Hz of about 0.1 to about 200 Pascal seconds, a G' value of about 0.1 to about 15000 dynes/sq cm over a strain range of 1 to 5% and a G" value of about 0.1 to about 2000 dynes/sq cm over a strain range of 1 to 5% which comprises approximately by weight 2 to 25 wt % of a glycolipid surfactant having an HLB of about 0.1 to about 8.0; 0.1 to 10.0 wt % of a polymeric thickener; 0.1 to 8 wt. % of an anionic surfactant; and the balance being water.

A thickened composition having a complex viscosity at 25.degree. C. and 1.58 Hz of about 0.1 to about 200 Pascal seconds, an elastic modulus G' value of about 0.1 to about 15000 dynes/sq cm over a strain range of 1 to 5% and a viscous modulus G" value of about 0.1 to about 2000 dynes/sq cm over a strain range of 1 to 5% which comprises approximately by weight:
- (a) 0.25 to 25% of a glycolipid surfactant having an HLB of about 0.1 to about 8.0;
- (b) 0.1 to 10.0% of a polymeric thickener which is a nonionic polymer wherein said nonionic polymer 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 25 carbon atoms;
- (c) 0.1 to 8% of an anionic surfactant;
- and (d) the balance being water, wherein said polymeric thickener forms lipophilic-lipophilic bridges with said glycolipid surfactant and said anionic surfactant.
