Abstract
The present invention relates to compositions of peroxycarboxylic acid that have reduced odor compared to conventional peroxycarboxylic acid compositions, methods employing these reduced-odor compositions, and methods of making these compositions. Typically, the reduced-odor compositions include an amine oxide surfactant.
Claims12
A reduced-odor peroxycarboxylic acid composition comprising:
- at least one peroxycarboxylic acid;
- and
- amine oxide of the formula (R1R2R3)NO, wherein R1, R2, and R3 are alkyl groups, the R1 alkyl group having 4 to 18 carbon atoms, and the R2 and R3 alkyl groups having 1 to 2 carbon atoms;
- the amine oxide being effective for reducing the odor of the peroxycarboxylic acid;
- the composition comprising 2 to 5 moles of amine oxide per mole of peroxycarboxylic acid.

A reduced-odor peroxycarboxylic acid composition comprising:
- peroxyacetic acid;
- and
- octyl dimethyl amine oxide or octyl diethyl amine oxide;
- the amine oxide being effective for reducing the odor of the peroxycarboxylic acid;
