Abstract

Antimicrobial compositions including PCMX and carboxylic acid and related methods are described. In a preferred embodiment, an antimicrobial composition comprises an enhanced synergistically effective antimicrobial mixture of PCMX, carboxylic acid, glycerol, isopropanol, and sodium dodecyl sulfate.

Claims

1. An antimicrobial composition comprising:

parachlorometaxylenol (PCMX) in an amount of 1.0% w/w to 3.0% w/w;

carboxylic acid in an amount of 0.1% w/w to 0.3% w/w;

glycerol in an amount of 0.01% w/w to 0.2% w/w;

isopropanol in an amount of 0.6% w/w to 0.9% w/w;

sodium dodecyl sulfate in an amount of 0.5% w/w to 3.0% w/w; and

water wherein said carboxylic acid is selected from benzoic acid or salicylic acid.

2. The composition of claim 1, wherein the carboxylic acid is selected from the group consisting of citric acid, acetic acid, salicylic acid, benzoic acid, and a combination thereof.

3. The composition of claim 1, wherein the carboxylic acid comprises salicylic acid.
