Abstract
A peroxyacid antimicrobial concentrate and use composition is provided comprising a C.sub.5 peroxyacid in combination with a C.sub.1 14 C.sub.4 peroxyacid, a C.sub.6 -C.sub.18 peroxyacid, or mixtures thereof. The combination of these peracids produces a synergistic effect, providing a much more potent biocide than can be obtained by using these components separately. Other components can be added to the composition such as hydrotrope coupling agents, stabilizers, etc. An effective antimicrobial use solution is formed at low concentrations when the concentrate composition is diluted with water. Sanitizing of substantially fixed, "in-place" processing lines in dairies, breweries, and other food processing operations is one utility of the composition.
Claims21
A peroxyacid antimicrobial concentrate composition consisting essentially of:
- (a) an effective biocidal amount of peroxyglutaric acid;
- and
- (b) an effective biocidal amount of a peroxyacid selected from the group consisting of an aliphatic C.sub.6 -C.sub.18 aliphatic peroxyacid, and mixtures thereof;
- wherein the concentrate composition is capable of being diluted with a major proportion of water to form an antimicrobial use solution that can achieve a 5 log reduction in a microbial population at a pH in the range of about 2 to 8.
A peroxyacid antimicrobial concentrate composition consisting essentially of:
- (a) about to 1 to 25 wt-% of peroxyglutaric acid;
- (b) about 0.01 to 10 wt-% of a peroxyacid of the structure R.sub.1 --CO.sub.3 H, wherein R.sub.1 comprises an aliphatic hydrocarbon chain having about 5 to 17 carbon atoms;
- (c) about 0.1 to 30 wt-% of a hydrotrope coupling agent capable of solubilizing said peroxyacid of (b) in the concentrate and when the concentrate is diluted with water;
- and
- (d) about 1 to 50 wt-% of hydrogen peroxide;
- wherein the concentrate composition is capable of being diluted with a major proportion of water to form an antimicrobial sanitizing use solution that can achieve a 5 log reduction in a microbial population at a pH in the range of about 3 to 7.
