Abstract:
A microemulsion cleaning composition consisting essentially of approximately by weight:(a) 0.1 wt % to 8% of an anionic selected from the group consisting of sulfonated surfactants and sulfated surfactants;(b) 0.5% to 6% of an cthoxylated/propoxylated nonionic surfactant;(c) 0.5% to 8% of a short chain amphiphiles formed from the condensation product of an alkanol, and ethylene oxide wherein said short chain amphiphile has the formula:R.sub.1 O (CH.sub.2 CH.sub.2 O).sub.n Hwherein R.sub.1 is a straight or branched chain alkyl group having 5 to 8 carbon atoms and n is a number from 2 to 8;(d) 0.05% to 2% of a fatty acid;(c) 0.25% to 6% of magnesium sulfate;(f) 0.1 to 5% of a water insoluble hydrocarbon, essential oil or a perfume;(g) 0.05% to 2% of a sodium salt of an olefin maleic acid copolymer; and(h) the balance being water wherein the composition does not contain a composition which is a water-soluble polyethylene glycols having a molecular weight of 150 to 1000, polypropylene glycol of the fonnula HO(CH.sub.3 CHCH.sub.2 O).sub.n H wherein n is a number from 2 to 18, mixtures of polyethylene glycol and polypropylene glycol and mono and di C.sub.1 -C.sub.4 alkyl ethers and esters of ethylene glycol and propylene glycol having the structural formulas R(X).sub.n OH, R.sub.1 (X).sub.n OH, R(X).sub.n OR and R.sub.1 (X).sub.n OR.sub.1 wherein R is C.sub.1 -C.sub.6 alkyl group, R.sub.1 is C.sub.2 -C.sub.4 acyl group, X is (OCH.sub.2 CH.sub.2) or (OCH.sub.2 (CH.sub.3)CH) and n is a number from 1 to 4, diethylene glycol, triethylene glycol, an alkyl lactate, wherein the alkyl group has 1 to 6 carbon atoms, 1methoxy-2-propanol, 1methoxy-3-propanol, and 1methoxy 2-, 3- or 4-butanol and the composition has a pH in the neutral range.
