Abstract

The present invention is for an acidic cleaning composition which has excellent cleaning performance, low toxicity and good antimicrobial efficacy. The inventive acidic cleaning compositions are capable of sanitizing or disinfecting a variety of hard surfaces. The inventive acidic cleaning compositions can take a variety of forms, such as: disinfecting wipes, all-purpose disinfecting sprays, kitchen cleaners, bathroom cleaners, toilet cleaners, etc. The inventive acidic cleaning compositions have good cleaning properties and low residue.

First claim

We claim:

1. A concentrated acidic cleaning composition comprising:
a) about 0.03% to 80% by weight of a citric acid;
b) about 0.01% to 2% by weight of alkyl sulfate surfactant;
c) about 10% to 30% by weight of an alkyl polyglucoside surfactant;
d) about 0.01% to 10% of one or more organic solvents selected from the group consisting of C1-18 alkanols, C1-18 diols, C3-24 alkylene glycol ethers, polyalkylene glycols, short chain carboxylic acids, short chain esters, and any mixture or combinations thereof;
e) about 0.1% to 3% methanesulfonic acid;
f) less than 85% by weight of water; and
g) optionally, one or more adjuvants selected from the group consisting of fragrances or perfumes, waxes, dyes, colorants, solubilizing materials, stabilizers, thickeners, defoamers, hydrotropes, buffers, builders, lotions, mineral oils, cloud point modifiers, polymers, preservatives and any combinations or mixtures thereof; wherein the composition requires a 1:10 to 1:50 dilution with water prior to use; and wherein the pH of the diluted composition is less than 7.

2. The concentrated composition of claim 1 , wherein the composition further comprises a fragrance.

3. The concentrated composition of claim 1 , wherein the composition further comprises a colorant.

4. The concentrated composition of claim 1 , wherein the composition is loaded onto a substrate after at least a 1:10 dilution.

5. The concentrated composition of claim 1 , wherein the composition is diluted in a spray bottle with at least a 1:10 dilution.

6. The concentrated composition of claim 1 , wherein the composition is diluted in a dispensing container with at least a 1:10 dilution.

7. The composition of claim 1 , wherein the composition is free of cationic surfactants.

8. The composition of claim 1 , wherein the alkyl sulfate surfactant is sodium lauryl sulfate.
