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 (36)

1. A cleaning composition comprising:

spore, bacteria, fungi, or enzyme;

alkanol amine borate; and

amine antimicrobial agent of the formula:

[(R 1 )NH(R 2 )NH 3 ] + (CH 3 COO) −

or

[(R 1 )NH 2 (R 2 )NH 3 ++ ](CH 3 COO) 2 − ;

in which:

R 1 is C10-C18 aliphatic group or an ether group having the formula R 10 OR 11 ;

in which R 10 is a C10-C18 aliphatic group and R 11 is a C1-C5 alkyl group; and

R 2 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.

7. A cleaning composition comprising:

spore, bacteria, fungi, or enzyme;

borate salt; and

amine antimicrobial agent of the formula

[(R 1 )NH(R 2 )NH 3 ] + (CH 3 COO) −

or

[(R 1 )NH 2 (R 2 )NH 3 ++ ](CH 3 COO) 2 − ;

in which:

R 1 is C10-C18 aliphatic group or an ether group having the formula R 10 OR 11 ;

in which R 10 is a C10-C18 aliphatic group and R 11 is a C1-C5 alkyl group; and

R 2 is a C1-C5 alkylene group;

the composition being substantially free of sodium ion.

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.

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