Abstract

A liquid cleaning composition including: at least 80 wt. % liquid solvent; a cationic quaternary amine biocide; and a non-cationic, amine oxide moisturizing agent.

First claim

The invention claimed is:

1. A liquid cleaning composition comprising:
at least 80 wt. % water;
0.06 wt. % to 1 wt. % benzalkonium chloride;
0.7 wt. % to 3 wt. % glycerin;
0.01 wt. % to 5 wt. % of a polycarboxylic acid and/or a salt thereof;
0.01 wt. % to 1 wt. % myristamidopropylamine oxide;
0.5 wt. % to 5 wt. % cetrimonium chloride;
PEG-5 isononanoate;
1.5 wt. % to 1.8 wt. % lauramidopropylamine oxide; and
0.02 wt. % to 0.8 wt. % of zinc sulfate nanoparticles having an average axis length of between 20 nm and 60 nm,
wherein the composition reduces bacteria by at least 2.0 log 10 when assessed using ASTM E1174.

2. The composition of claim 1 , wherein the polycarboxylic acid and/or the salt thereof comprises three carboxyl groups per molecule.

3. The composition of claim 1 , wherein the polycarboxylic acid and/or the salt thereof comprises an acid selected from the group consisting of citric acid, a citrate salt, ethylenediaminetetraacetic acid (EDTA), an EDTA salt, oxalic acid, an oxalate salt, and any mixture thereof.

4. The composition of claim 1 , wherein the composition comprises at least 90 wt. % water.

5. The composition of claim 1 , further comprising an unmodified polyethylene glycol of 5 to 18 C 2 H 4 repeating units linked by ether bonds.

6. The composition of claim 1 , further comprising 0.001 wt. % to 5 wt. % of fatty amides.

7. The composition of claim 6 , wherein the fatty amides are selected from the group consisting of cocamidopropyl betaine, lauramidopropyl betaine, and a mixture thereof.

8. The composition of claim 1 , further comprising a non-ionic surfactant.

9. The composition of claim 1 , wherein the composition reduces drying of the stratum corneum with a water control between 30 and 180 minutes after application as assessed with a lower leg-controlled application test.

10. The composition of claim 1 , wherein the composition is substantially free of mono-alcohols with five or fewer carbons.

11. The composition of claim 4 , wherein the composition comprises at least 92 wt. % water.

12. A liquid cleaning composition comprising:
at least 92 wt. % water;
0.11 wt. % to 0.26 wt. % benzalkonium chloride;
about 1.5 wt. % glycerin;
about 0.7 wt. % citric acid;
about 0.19 wt. % myristamidopropylamine oxide;
about 1.64 wt. % lauramidopropylamine oxide;
0.7 wt. % to 2.77 wt. % cetrimonium chloride;
about 0.19 wt. % PEG-5 isononanoate; and
0.05 wt. % to 0.1 wt. % zinc sulfate nanoparticles having an average axis length of between 20 nm and 60 nm.

13. The composition of claim 12 , wherein the composition reduces bacteria by at least 2.0 log 10 when assessed using ASTM E1174.

14. The composition of claim 12 , wherein the composition further comprises:
about 0.4 wt. % cocamidopropyl betaine; and
about 0.21 wt. % PEG 9.

15. The composition of claim 1 , wherein the zinc sulfate nanoparticles have a longest mean axis length of 30 nm.

16. The composition of claim 12 , wherein the zinc sulfate nanoparticles have a longest mean axis length of 30 nm.
