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 method of cleaning a hard surface, comprising applying to the surface a cleaning composition comprising:

spore, bacteria, fungi, or enzyme;

borate salt;

an amine antimicrobial agent of the formula;

[(R¹)NH(R²)NH₃]⁺(CH₃COO)⁻

,

wherein 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;

nonionic surfactant; and

, optionally,

about 0.1 to about 35 wt-% silicone surfactant, wherein the composition provides greater than 3 log₁₀ reduction of bacteria within a 5 minute contact time.

2. A method of increasing the coefficient of friction of a hard surface, comprising applying to the surface a cleaning composition comprising:

spore, bacteria, fungi, or enzyme;

borate salt;

an amine antimicrobial agent of the formula;

[(R¹)NH(R²)NH₃]⁺(CH₃COO)⁻

,

wherein 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;

nonionic surfactant; and

, optionally,

about 0.1 to about 35 wt-% silicone surfactant, wherein the composition provides greater than 3 log₁₀ reduction of bacteria within a 5 minute contact time.

3. A method of cleaning grout, comprising applying to the grout a cleaning composition comprising:

spore, bacteria, fungi, or enzyme;

borate salt;

an amine antimicrobial agent of the formula;

[(R¹)NH(R²)NH₃]⁺(CH₃COO)⁻

,

wherein 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;

nonionic surfactant; and

, optionally,

about 0.1 to about 35 wt-% silicone surfactant, wherein the composition provides greater than 3 log₁₀ reduction of bacteria within a 5 minute contact time.
