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.
Claims5
A solid triamine composition comprising a matrix of the triamine and diacid and further comprising one or more of an enzyme, chelant, and/or sulfate inorganic hardening agent, the solid triamine composition formed by a process comprising:
- providing a composition comprising between about 10 and about 99 wt-% triamine, wherein the triamine has any one of the following formulas:
- R—NH—[(CH2)rNH]y—(CH2)m—NH2
- R—N[(CH2)rNH2]2
- wherein:
- R is linear or branched alkyl residue with 1 to 22 carbon atoms;
- m, r, and y independently represent an integer ranging from 1 to 6;
- between about 1 and about 50 wt-% of a diacid consisting of acetic acid, adipic acid, aspartic acid, dipicolinic acid, malic acid, malonic acid, oxalic acid, succinic acid, or tartaric acid or combinations thereof;
- and
- one or more of an enzyme, chelant and/or a sulfate inorganic hardening agent;
- wherein the ratio of the diacid to the triamine is from about 1:10 to about 1:1, combining the triamine, diacid, and one or more of an enzyme, chelant, and/or sulfate inorganic hardening agent;
- and
- at least partially neutralizing the triamine and diacid to form a solid composition;
- wherein the composition forms a solid and remains solid below about 50° C. without casting or extrusion.
