Claims2
A clear microemulsion or nonmicroemulsion light duty liquid cleaning composition which consists of by weight:
- (a) 10% to 45% of a mixture of an alkali metal salt of an anionic sulfonate surfactant and an alkali metal salt of a C.sub.8-C.sub.18 ethoxylated alkyl ether sulfate and/or a C.sub.8-C.sub.18 alkyl ether sulfate wherein the weight ratio of the sulfonate surfactant to the sulfate surfactant is from 15:1 to 1:1;
- (b) 0% to 10% of an ethoxylated nonionic surfactant;
- (c) 0.1% to 4% of a polyethylene glycol;
- (d) 0 to 14% of a cosurfactant, wherein said cosurfactant is selected from the group consisting of polyethylene glycols having a molecular weight of 150 to 1000, polypropylene glycol of the formula HO((CH3)CHCH2O)nH, wherein n is 1 to 18, polyethylene and propylene glycol ethers and esters having the formula of R(X)nOH, R1(X)nOH, R(X)nOR, R(X)nOR1, R1(X)nOR and R1(X)nOR1 wherein R is a C1-6 alkyl group, R1 is a C1-6 acyl group, X is (OCH2CH2) or (OCH2CHCH3) and n is from 1 to 8 and mixtures thereof;
- (e) 0 to 5% of an inorganic magnesium salt;
- (f) 0.5% to 8% of water insoluble organic ester or a water insoluble material selected from the group consisting of terpenes and essential oils;
- (g) 0 to 2% of a thickener and
- (h) the balance being water.
