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.

First claim

What is claimed is:

1. 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—[(CH 2 ) r NH] y —(CH 2 ) m —NH 2

R—N[(CH 2 ) r NH 2 ] 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.

2. The composition of claim 1 , wherein the enzyme is a lipase.

3. The composition of claim 1 , further comprising at least one functional ingredient selected from the group consisting of: surfactants, chelating agents, sequestering agents, detergents, alkaline sources, builders, rinse aids, hardening agents, bleaching agents, sanitizers, activators, builders, fillers, defoaming agents, anti-redeposition agents, optical brighteners, dyes, odorants, stabilizing agents, dispersants, enzymes, corrosion inhibitors, thickeners and solubility modifiers.

4. The composition of claim 1 , further comprising one or more functional siloxane(s).

5. The composition of claim 1 , wherein the concentration of the triamine is between about 10 and about 70 wt-%, the concentration of the diacid is between about 2.5 and about 40 wt-%, and additionally comprising a chelant having a concentration between about 1 and about 40 wt-%.
