Abstract
Renewable, non-volatile cleaning compositions incorporating ethyl ester solvents are disclosed. Preferred compositions employ non-volatile C8-16 ethyl ester solvents. All-purpose cleaning compositions incorporating the non-volatile C8-16 ethyl ester solvents, further include an alkyl polyglycoside surfactant, an alcohol ethoxylate surfactant, and water. Preferably the compositions are free of anionic, cationic and amphoteric surfactants and/or co-solvents. The invention also discloses methods employing the non-volatile solvent all-purpose cleaning compositions.
Claims18
An all-purpose cleaning composition comprising:
- from about 0.1-50 wt-% of a non-volatile C8-16 ethyl ester solvent replacing at least about 40% of conventional solvents, wherein said solvent is ethyl laurate;
- from about 0.1-50 wt-% of an alkyl polyglycoside surfactant;
- from about 0.1-50 wt-% of undeceth-5;
- water;
- a chelating agent that is either sodium citrate or glutamic acid diacetic acid;
- and
- at least one additional functional ingredient, wherein the composition is free of anionic, cationic and amphoteric surfactants.
An all-purpose cleaning composition comprising:
- from about 0.1-25 wt-% of a C10-14 ethyl ester non-volatile solvent replacing at least about 50% of conventional solvents, wherein said solvent is ethyl laurate;
- from about 1-20 wt-% of an alkyl polyglycoside surfactant and from about 1-20 wt-% of undeceth-5;
- from about 0.1-25 wt-% of a sodium citrate or glutamic acid diacetic acid chelating agent;
- and
- water, wherein the composition is free of anionic, cationic and amphoteric surfactants, and wherein the composition is free of chlorinated solvents, methyl esters, and aromatic hydrocarbons, and wherein the composition has a pH between about 4 and about 10.
