Couplers for medium-chain fatty acids and disinfecting compositions
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.
1. A solid concentrate antimicrobial composition for cleaning comprising:
about 0.05 wt-% to about 20 wt-% of at least one carboxylic acid antimicrobial agent, wherein the at least one carboxylic acid antimicrobial agent is decanoic acid; and
about 0.1 wt-% to about 30 wt-% nonionic surfactant, wherein said nonionic surfactant is an ethoxylated amine;
wherein the nonionic surfactant and carboxylic acid antimicrobial agent have a weight ratio of about 5.5:1 to about 3:1;
wherein said ethoxylated amine has a hydrophile-lipophile balance (HLB) from about 7.5 to about 14; and
wherein upon dilution, the composition produces a clear solution and has effective antimicrobial activity.
2. The composition of claim 1 further comprising a C6-Ci6 alkyl carboxylic acid, salt or ester thereof.
3. The composition of claim 2 wherein said C6-C12 alkyl carboxylic acid comprises octanoic acid, heptanoic acid, nonanoic acid, dodecanoic acid, myristic acid, isomers thereof, or mixtures thereof.
4. The composition of claim 1 further comprising a sequestrant, acidulant, stabilizing agent, wetting agent, thickener, foaming agent, pigment dye or mixtures thereof.
5. The composition of claim 1 , wherein said ratio of ethoxylated amine to decanoic acid is about 4.5:1.
6. A solid shower cleaning composition comprising:
about 0.05 wt-% to about 10 wt-% of at least one fatty acid antimicrobial agent, wherein the at least one fatty acid antimicrobial agent is decanoic acid;
about 0.15 wt-% to about 55 wt-% ethoxylated amine of one of the following formulas:
wherein R is selected from the group consisting of a straight alkyl, branched alkyl, or alkylaryl substituent, having from 1 to 24 carbon atoms, and wherein n is from 1 to 20;
wherein the ethoxylated amine and fatty acid antimicrobial agents being at a weight ratio of about 5.5:1 to about 3:1;
wherein said ethoxylated amine has a hydrophile-lipophile balance (HLB) from about 7.5 to about 14; and
wherein the composition produces a clear use solution upon dilution with a solvent and has effective antimicrobial activity.
7. The composition of claim 6 further comprising octanoic acid, heptanoic acid, nonanoic acid, dodecanoic acid, myristic acid, isomers thereof, or mixtures thereof.
8. The composition of claim 6 wherein said HLB is from about 10 to about 14.
9. The composition of claim 6 wherein R is a substituent comprising a mixture of saturated and unsaturated fatty acids with 6-18 carbons.
10. The composition of claim 6 wherein R is substituent derived from coconut oil.
11. The composition of claim 6 wherein said ratio of ethoxylated amine and decanoic acid is about 5.5:1 to about 4:1.
12. The composition of claim 1 , wherein the ethoxylated amine is ethoxylated cocoamine 10E0.
13. The composition of claim 6 , wherein the composition is highly bio-based, non-irritating, and non-corrosive.
