Abstract
A disinfecting shower cleaner composition including a medium-chain fatty acid coupled with a nonionic surfactant providing temperature stable antimicrobial compositions. The invention specifically relates to antimicrobial compositions including fatty acid antimicrobial agents coupled with an ethoxylated amine and methods of using the antimicrobial compositions.
Claims12
An antimicrobial composition for cleaning comprising:
- about 0.05 wt-% to about 20 wt-% decanoic acid;
- and
- about 0.1 wt-% to about 30 wt-% nonionic ethoxylated amine surfactant having a hydrophile-lipophile balance (HLB) from about 10 to about 14;
- and
- a citric acid acidulant;
- wherein the nonionic ethoxylated amine surfactant and decanoic acid have a weight ratio of about 5.5:1 to about 3:1 and the composition is clear and has effective antimicrobial activity;
- and
- wherein the nonionic ethoxylated amine surfactant couples the decanoic acid into an acidic composition without complexing or reacting with the decanoic acid;
- and
- wherein the weight ratio of citric acid acidulant to decanoic acid is at least 27:1
- to provide said acidic composition.

An antimicrobial composition for cleaning comprising:
- about 0.05 wt-% to about 10 wt-% decanoic acid;
- about 0.15 wt-% to about 55 wt-% ethoxylated amine of one of the following formulas:
- and
- a citric acid acidulant;
- wherein R is a straight or branched alkyl or alkylaryl substituent having from 1 to 24 carbon atoms;
- wherein said ethoxylated amine has an HLB from about 10 to about 14;
- wherein the ethoxylated amine and decanoic acid being at a weight ratio of about
- 5.5:1 to about 3:1;
- wherein the ethoxylated amine couples the decanoic acid into an acidic composition without complexing or reacting with the decanoic acid;
- wherein the weight ratio of citric acid acidulant to decanoic acid is at least 27:1
- to provide said acidic composition;
- and
- wherein the composition is clear and has effective antimicrobial activity.
