Abstract
The present invention relates generally to compositions and methods for cleaning hard surfaces. More particularly, the present invention relates to cleaning compositions which can be used in automotive applications for removing organic soils that accumulate on automotive surfaces without causing surface paint damage. Such cleaning compositions of the present invention are environmentally safe and contain no or low amounts of volatile organic compounds.
Claims37
A composition for cleaning hard surfaces comprising:
- (a) about 0.001% to about 0.5% by weight of a surfactant;
- (b) about 0.001% to about 2% by weight of an ammonia compound;
- (c) about 0.001% to about 0.80% by weight of an alcohol;
- and
- (d) balance being water,
- wherein the total alcohol content is no more than about 0.80% by weight of the composition.
A composition for cleansing hard surfaces comprising:
- (a) about 0.001% to about 0.25% by weight of a surfactant;
- (b) about 0.005% to about 1.0% by weight of an ammonia compound;
- (c) about 0.005% to about 0.80% by weight of an alcohol;
- (d) balance being water;
- wherein the total alcohol content is no more than about 0.80% by weight of the composition.
A composition for cleansing hard races comprising:
- (a) about 0.005% to about 0.1% by weight of a surfactant;
- (b) about 0.01% to about 0.75% by weight of an ammonia compound;
- (c) about 0.01% to about 0.70% by weight of an alcohol;
- (d) balance being water;
- wherein the total alcohol content is no more that about 0.08% by weight of the composition.
A composition for cleansing hard surfaces comprising:
- (a) about 0.01% to about 0.075% by weight of a surfactant;
- (b) about 0.05% to about 0.50% by weight of an ammonia compound;
- (c) about 0.05% to about 0.60% by weight of an alcohol;
- (d) balance being water;
- wherein the total alcohol content is no more that about 40.80% by weight of the composition.
A composition for cleansing hard surfaces comprising:
- (a) about 0.01% to about 0.05% by weight of a surfactant;
- (b) about 0.07% to about 0.30% by weight of an ammonia compound;
- (c) about 0.1% to about 0.50% by weight of an alcohol;
- (d) balance being water;
- wherein the total alcohol content no more that about 0.80% by weight of the composition.
A method for evaluating the effectiveness of cleaning composition, comprising the steps of:
- (a) contacting a sample with said cleaning composition, wherein said sample comprises a soil;
- (b) calculating rate of penetration of said composition into said soil;
- (c) calculating removal effectiveness.
