Abstract
This invention relates to a liquid crystal composition comprising a water insoluble organic compound, an ethoxylated nonionic surfactant, an alkyl polyglucoside surfactant, an ethoxylated alkyl ether sulfate surfactant, a cosurfactant and water.
Claims8
A liquid crystal detergent composition which comprises by weight:
- (a) about 1% to about 30% of an ethoxylated nonionic surfactant containing ethylene oxide groups;
- (b) about 0.1% to about 16% of an alkyl polyglucoside surfactant;
- (c) about 1% to about 20% of a water soluble salt of an ethoxylated C.sub.8-18 alkyl ether sulfate surfactant or sodium lauryl sulfate;
- (d) about 0.1% to about 2% of an alcohol having the formula CnH2n+2-x(OH)x wherein x is 2 or 3 and n is a number from 2 to 5;
- (e) about 0.1% to about 6% of a fatty alcohol having a single oxygen atom and a total of 14 to 20 carbon atoms;
- (f) about 1% to about 30% of a water soluble glycol ether cosurfactant;
- (g) about 0.6% to about 10% of a water insoluble organic compound selected from the group consisting of perfumes, essential oils and water insoluble hydrocarbons;
- (h) 1% to 10% of a magnesium salt;
- and
- (i) 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 one phase at a temperature of 8.degree. C. to 43.degree. C.
