Abstract
A terpene-free cleaning composition containing: (a) an oil-soluble anionic surfactant; (b) a water-soluble anionic surfactant; (c) a primary solvent consisting of a C1-4 alkyl ester; (d) a short-chain cosurfactant; and (e) water.
Claims35
A terpene-free cleaning composition comprising:
- (a) a C1-4 alkyl ester of a C6-22 saturated or unsaturated carboxylic acid;
- and
- (b) a cyclic ketone, wherein (a) and (b) are employed at a ratio by weight of from about 10:1 to about 1:10.
A terpene-free cleaning composition comprising:
- (a) from about 2 to about 12% by weight of an oil-soluble anionic surfactant;
- (b) from about 0.2 to about 6% by weight of a water-soluble anionic surfactant;
- (c) from about 3 to about 96% by weight of a primary solvent consisting of a C1-4 alkyl ester of a C6-22 saturated or unsaturated carboxylic acid;
- (d) from about 2 to about 14% by weight of a short-chain cosurfactant;
- and
- (e) remainder, water, all weights being based on the total weight of the composition.
