Abstract:
A blue colored liquid crystal detergent composition which comprises by weight:(a) about 1% to about 10% of an ethoxylated nonionic surfactant containing ethylene oxide groups; (b) about 0.5% to about 6% of a water soluble salt of an ethoxylated C8-18 alkyl ether sulfate surfactant; (c) 10% to 22% of a calcium carbonate abrasive; (d) 10% to 24% of a sodium salt of a C8-C16 linear alkyl benzene sulfonate surfactant; (e) 0.5% to 6% of a magnesium, sodium, calcium or potassium inorganic salt; (f) 0.005% to 0.1% of a blue colorant; and (g) the balance being water, wherein said liquid crystal detergent composition has a storage modulus measured at a temperature between 20Â° C. to 40Â° 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 8Â° C. to 43Â° C. and said composition does not contain an zwitterionic surfactant or a cosurfactant such as glycerol, ethylene glycol, water-soluble polyethylene glycols, polypropylene glycols, mono C1-C6 alkyl ethers and esters of ethylene glycol and propylene glycol.
