Abstract
Stable, solid triamine compositions are disclosed. The pressed, cast, extruded or other solid compositions are suitable for antimicrobial, sanitizing and disinfectant applications. Ready-to-use solutions are obtained by dissolving the solid triamine compositions with water and the methods of use thereof are particularly suitable for cleaning, disinfecting, sanitizing, rinsing and/or lubricating. Beneficially, the solid triamine compositions are at least partially neutralized, allowing activity of 90% and greater of the biocidal triamine, and provide at least substantially similar or superior performance and micro efficacy to liquid formulations.
Claims21
1-20. (canceled)
A solid triamine composition comprising:
- a triamine comprising any one of the following formulas:
- R—NH—[(CH2)rNH]y—(CH2)m—NH2
- R—N[(CH2)rNH2]2
- wherein:
- R is a linear or branched alkyl residue with 1 to 22 carbon atoms,
- m, r, and y independently represent an integer ranging from 1 to 6;
- a solid acid comprising citric acid, tartaric acid, benzoic acid, mandelic acid, sulfamic acid, malic acid, malonic acid, maleic acid, succinic acid, adipic acid, aspartic acid, iminodiacetic acid, glycine, lysine, gluconic acid, glutamic acid, dipicolinic acid, octanoic acid, decanoic acid, sorbic acid, fumaric acid, oxalic acid, or combinations thereof;
- and
- a surfactant comprising an amine oxide surfactant,
- wherein the ratio of the solid acid to the triamine is from about 1:10 to about 1:1, and
- wherein the combination of the triamine and the solid acid forms an at least partially neutralized solid matrix.
The method of claim 18, wherein the use solution of the solid triamine compositions provides between about 1 ppm to about 500 ppm triamine, and between about 1 ppm to about 250 ppm solid acid.
