Abstract
This invention relates to a liquid crystal composition comprising a water insoluble organic compound, a sulfonate surfactant, an abrasive, an ethoxylated alkyl ether sulfate surfactant, a cosurfactant and water.
Claims5
A liquid crystal detergent composition which comprises by weight:
- (a) about 15% to about 30% of a sodium paraffin sulfonate;
- (b) about 2% to about 20% of a water soluble salt of an ethoxylated C.sub.8-18 alkyl ether sulfate surfactant;
- (c) about 1% to about 10% of an abrasive which is selected from the group consisting of calcite, amorphous hydrated silica, polyethylene powder and mixtures thereof;
- (d) about 2% to about 15% of tripropylene glycol n-butyl ether;
- (e) about 4% to about 10% of a water insoluble organic compound selected from the group consisting of perfumes, essential oils and water insoluble hydrocarbons having about 8 to about 18 carbon atoms;
- and
- (f) the balance being water, wherein said liquid crystal detergent composition has a storage modulus measured at a temperature between 20.degree. C. to 40.degree. C., at a strain of 0.1% to 5% and a frequency of 10 radians/second of at least about one Pascal and said composition does not contain any nonionic surfactant.
