Abstract
This invention relates to a liquid crystal composition comprising a water insoluble organic compound, a nonionic surfactant, magnesium sulfate, a water soluble cosurfactant, an abrasive, an ethoxylated alkyl ether sulfate surfactant or alkyl sulfate surfactant, a fatty acid, a 2-alkyl alkanol and water.
Claims7
A clear liquid crystal composition which comprises by weight:
- (a) about 0.5% to about 20% of one nonionic surfactant containing ethylene oxide groups and having a HLB of 7.5 to 8.5;
- (b) about 1% to about 20% of a water soluble salt of an ethoxylated C.sub.8 to C.sub.18 alkyl ether sulfate surfactant or C.sub.8 -C.sub.18 alkyl sulfate surfactant;
- (c) about 0.1% to about 5% of an abrasive;
- (d) about 0.5% to about 10% of an 2-alkyl alkanol wherein said 2-alkyl alkanol has the structure:
- ##STR3## wherein R.sub.1 is a C.sub.4 to C.sub.10 alkyl group and R.sub.2 is a C.sub.4 to C.sub.10 alkyl group and has a total of 10 to 22 carbon atoms;
- (e) about 0.5% to about 8% 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 mixtures thereof;
- (f) 1% to 15% of a water soluble glycol ether cosurfactant;
- and
- (g) the balance being water, 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 is thermally stable and exists as said clear liquid crystal composition and is one phase in the temperature range of 8.degree. C. to 43.degree. C. wherein the composition does not contain any hydroxy-containing alkyl glycamide surfactant or any organic or in organic detergent builder salt.
