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.
Claims20
A solid triamine composition formed by a process comprising:
- providing a 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 diacid comprising adipic acid, aspartic acid, dipicolinic acid, malic acid, malonic acid, oxalic acid, succinic acid, or tartaric acid or combinations thereof;
- and
- two or more of an amine oxide surfactant, a functional siloxane surfactant or an enzyme, wherein the ratio of the diacid to the triamine is from about 1:10 to about 1:1;
- combining the triamine, the solid diacid, and the two or more of the amine oxide surfactant, the functional siloxane surfactant or the enzyme;
- and
- at least partially neutralizing the triamine and the solid diacid to form a solid matrix;
- wherein the composition is formed at a temperature of between about 21° C. and about 55° C. without casting or extrusion.
