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
A solid triamine composition comprising:
- between about 10 and about 99 wt-% triamine;
- and
- between about 1 and about 50 wt-% diacid,
- wherein the ratio of the diacid to the triamine is from about 1:10 to about 1:1, and
- wherein the triamine and diacid are combined in at least a partially neutralized solid composition, and wherein the composition remains solid below about 50° C.
A method of making a solid triamine composition comprising:
- at least partially neutralizing a triamine;
- reacting the biocidal triamine with a diacid to generate an amine salt;
- and
- solidifying the composition,
- wherein the solid composition remains solid below about 50° C., and wherein the ratio of the diacid to the triamine is from about 1:10 to about 1:1.
