Abstract

The present invention relates to a stable antimicrobial and cleaning compositions including an amine antimicrobial agent; a borate salt; and spores (bacterial or fungal), vegetative bacteria, fungi, or enzyme, and to methods of using the composition. The composition can also include a polyol.

Claims

1. A cleaning composition comprising:

spore, bacteria, fungi, or enzyme;

alkanol amine borate; and

amine antimicrobial agent of the formula;

[(R¹)NH(R²)NH₃]⁺(CH₃COO)⁻

or

[(R¹)NH₂(R²)NH₃⁺⁺](CH₃COO)₂⁻

;

in which;

R¹ is C10-C18 aliphatic group or an ether group having the formula R¹⁰OR¹¹;

in which R¹⁰ is a C10-C18 aliphatic group and R¹¹ is a C1-C5 alkyl group; and

R² is a C1-C5 alkylene group.

2. The composition of claim 1, wherein the composition has pH greater than or equal to 8.

3. The composition of claim 1, further comprising polyol.

4. The composition of claim 1, comprising about 5 to about 35 wt-% alkanol amine borate and the alkanol amine borate comprises monoethanolammonium borate, diethanolammonium borate, triethanolammonium borate, or a combination thereof.

5. The composition of claim 1, further comprising about 0.003 to about 35 wt-% nonionic surfactant and the nonionic surfactant comprises:

nonionic block copolymer comprising of at least (EO)_y(PO)_z, wherein y and z are independently between 2 and 100;

C_6-24 alkyl phenol alkoxylate having 2 to 15 moles of ethylene oxide;

C_6-24 alcohol alkoxylate having 2 to 15 moles of ethylene oxide;

alkoxylated amine having 2-20 moles of ethylene oxide;

or mixtures thereof.

6. The composition of claim 1, further comprising about 0.0005 to about 35 wt-% silicone surfactant.

8. The composition of claim 1, further comprising detersive enzyme.

9. The composition of claim 8, wherein the detersive enzyme comprises protease, amylase, lipase, cellulase, peroxidase, gluconase, or mixtures thereof.

7. A cleaning composition comprising:

spore, bacteria, fungi, or enzyme;

borate salt; and

amine antimicrobial agent of the formula

[(R¹)NH(R²)NH₃]⁺(CH₃COO)⁻

or

[(R¹)NH₂(R²)NH₃⁺⁺](CH₃COO)₂⁻

;

in which;

R¹ is C10-C18 aliphatic group or an ether group having the formula R¹⁰OR¹¹;

in which R¹⁰ is a C10-C18 aliphatic group and R¹¹ is a C1-C5 alkyl group; and

R² is a C1-C5 alkylene group;

the composition being substantially free of sodium ion.

10. The composition of claim 7, further comprising about 0.1 to about 20 wt-% hydrotrope.
