Abstract
An improvement is described in all purpose liquid cleaning composition and microemulsion composition which are especially effective in the removal of oily and greasy soil and contains an anionic detergent, an ethoxylated/propoxylated nonionic surfactant, a short chain amphiphile and olefin/maleic acid copolymer, a hydrocarbon ingredient, and water and optionally, an ethoxylated nonionic surfactant.
Claims5
A microemulsion cleaning composition comprising 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 ethoxylated/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 H
- wherein 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;
- (e) 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 mixture of a partially esterified ethoxylated polyhydric alcohol, a fully esterified ethoxylated polyhydric alcohol and a nonesterified ethoxylated polyhydric alcohol.
