20210238135 · 2021-08-05 ·

Peroxyhydroxycarboxylic acid forming compositions and methods for forming peroxyhydroxycarboxylic acids, preferably in situ, using the peroxyhydroxycarboxylic acid forming compositions are disclosed. Methods of using the peroxyhydroxycarboxylic acids, including for treating a surface or a target in need of antimicrobial or sanitizing treatment are also disclosed. Particular applications of using odor-free, low volatility peroxyhydroxycarboxylic acid sanitizers for direct food contact are disclosed.

METHOD FOR QUENCHING PEROXYCARBOXYLIC ACID RUNAWAY REACTIONS

Systems for quenching peroxycarboxylic acid and peroxide chemistry runaway reactions provide safe and efficacious systems to prevent uncontrolled runaway reactions, such as decomposition reactions, of peroxycarboxylic acid and peroxide chemistry compositions are disclosed. The systems provide prompt detection and dispensing of a stabilizer into a tank or other storage vessel containing a peroxide composition, peroxycarboxylic acid composition or a peroxycarboxylic acid-forming composition to stop a runaway reaction. Methods for quenching peroxide and peroxycarboxylic acid runaway reactions are also disclosed.

POLYMERIC AND SOLID-SUPPORTED CHELATORS FOR STABILIZATION OF PERACID-CONTAINING COMPOSITIONS

Stabilized peroxycarboxylic acid compositions and the solid supported peracid stabilizers are provided. Methods of producing the solid supported peracid stabilizers are provided. The solid supported peracid stabilizers and the stable peroxycarboxylic acid compositions are particularly suitable for use in sanitizing equipment and surfaces to reduce yeasts, spores and bacteria, including those having contact with food, food products and/or components thereof, which require or benefit from infection control suitable for direct contact with such food sources.

Storage stable aqueous organic peroxide emulsions

Aqueous emulsion comprising: 25-70 wt % organic peroxide, based on the weight of the emulsion, a cyclohexane dicarboxylate ester, and water. This emulsion is storage stable and can be used for the production of polymers, in particular PVC, that come into contact with food products.

Methods for forming peroxyformic acid and uses thereof

The present invention relates generally to methods for forming peroxyformic acid, comprising contacting formic acid with hydrogen peroxide. The methods for forming peroxyformic acid can include adding formic acid with a relatively lower concentration of hydrogen peroxide, or adding formic acid to a peroxycarboxylic acid composition or forming composition to react with hydrogen peroxide in the compositions. The present invention also relates to peroxyformic acid formed by the above methods. The present invention further relates to the uses of peroxyformic acid for treating a variety of targets, e.g., target water, including target water used in connection with oil- and gas-field operations. The present invention further relates to methods for reducing or removing H.sub.2S or iron sulfide in the treated water source, improving clarity of the treated water source, or reducing the total dissolved oxygen or corrosion in the treated water source, using peroxyformic acid, including peroxyformic acid generated in situ.
