Low foaming, highly acidic peroxycarboxylic acid sanitizing compositions are disclosed as having both improved antimicrobial efficacy in comparison to conventional peroxyoctanoic acid and peroxyacetic acid compositions for sanitizing applications. The compositions include a combination of a low-foaming surfactant and an aluminum sulfate (or other metal salt) defoaming agent that is compatible with the highly acidic peroxycarboxylic acid sanitizing compositions. In particular, the sanitizing peroxycarboxylic acid compositions are also low odor and low/no VOC dual functioning acid wash and sanitizing compositions.

Defoamer useful in a peracid composition with anionic surfactants

A disinfectant wipe is provided including a substrate that is substantially free of polyamides, and an acid anionic disinfectant is adsorbed to the substrate such that the disinfectant readily releases from the substrate to allow at least 65% delivery of the disinfectant when wiped on a surface. The substrate may be a woven, nonwoven, knit fabric, a foam, sponge or film composition and may be formed from polyester, polypropylene, nylon, cotton, rayon, acrylic, or combinations thereof. The acid anionic disinfectant has a pH below 7, below 5, below 3 and below 2. The substrate used to prepare the disinfectant wipe is not pretreated with the disinfectant or a release composition before applying the disinfectant. That is, the disinfectant is not applied and re-applied to ensure release onto a surface. In an embodiment of the invention acid anionic disinfectant is an antimicrobial agent.

Non-sorptive or minimally sorptive disinfectant wipes

Methods of generating performic acid by contacting aqueous oxidizing agent and aqueous formic acid source in liquid phase are disclosed. A system and apparatus for the in situ production of the performic acid chemistries is further disclosed. In particular, a continuous flow reactor is provided to generate performic acid at variable rates. Methods of employing the oxidizing biocide for various disinfection applications are also disclosed.

Performic acid on-site generator and formulator

The present disclosure relates to rheology modified, low foaming aqueous antimicrobial compositions. The compositions are phase stable under acidic conditions, and do not need to be rinsed from the surface to which they are applied. The present disclosure further relates to methods of use thereof.

Rheology modified low foaming liquid antimicrobial compositions and methods of use thereof

The present invention relates to novel sulfoperoxycarboxylic acid compounds, and methods for making and using them. The sulfoperoxycarboxylic compounds of the invention are storage stable, water soluble and have low to no odor. Further, the compounds of the present invention can be formed from non-petroleum based renewable materials. The compounds of the present invention can be used as antimicrobials, and bleaching agents. The compounds of the present invention are also suitable for use as coupling agents.

Sulfoperoxycarboxylic acids, their preparation and methods of use as bleaching and antimicrobial agents

Methods and systems for temperature-controlled, on-site generation of peracids, namely peroxycarboxylic acids and peroxycarboxylic acid forming compositions are disclosed. In particular, methods for using an adjustable biocide formulator or generator system overcome the limitations of temperature on the kinetics of the peracid generation and/or peracid decomposition inside an adjustable biocide formulator or generator system. The methods include the controlling of the temperature of at least one raw starting material, namely water, to improve upon methods of on-site generation of peracids. The methods allow for the generation of user-selected chemistry without regard to the ambient temperatures of the raw starting materials and/or the biocide formulator or generator system.

Water temperature as a means of controlling kinetics of onsite generated peracids

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.

Polymeric and solid-supported chelators for stabilization of peracid-containing compositions

Antimicrobial compositions including at least one acid and at least one anionic surfactant are provided. In particular, food contact antimicrobial compositions including at least one acid and at least one anionic surfactant provide a no-rinse compositions efficacious against Norovirus, having acceptable use solution pH that do not require use of personal protective equipment (PPE), are surface compatible and do not leave residues on treated surfaces are provided. Methods of cleaning a surface with the compositions are also provided.

Acid/anionic antimicrobial and virucidal compositions and uses thereof

Antimicrobial compositions including at least one acid and at least one anionic surfactant are provided. In particular, food contact antimicrobial compositions including at least one acid and at least one anionic surfactant provide efficacious virucidal activity, including against Norovirus, having acceptable use solution pH that do not require use of personal protective equipment (PPE), are surface compatible and do not leave residues on treated surfaces. Methods of cleaning a surface with the compositions are also provided and may beneficially eliminate the need to rinse the antimicrobial compositions after use.

Solid acid/anionic antimicrobial and virucidal compositions and uses thereof

The present invention relates generally to stable percarboxylic acid compositions comprising, inter alia, at least two stabilizing agents, and various uses for water treatments, including water treatments in connection with oil- and gas-field operations. The present invention also relates to slick water compositions and gel based compositions that comprise stable percarboxylic acid compositions and the use thereof in oil- and gas-field operations.

Stable percarboxylic acid compositions and uses thereof

The present disclosure relates generally to peroxyformic acid forming compositions and methods for forming peroxyformic acid, preferably in situ, and peroxyformic acid formed by said compositions and methods for the purpose of treating an animal tissue and providing an antimicrobial function thereon. present disclosure in particular relates to a residue-free teat treatment composition for the treatment of an animal tissue, especially bovine teats, which provides antimicrobial efficacy and does not leave a non-food ingredient residue on treated teats.

On site generated performic acid compositions for teat treatment

Self-indicating chemistries are provided for visual detection by a user of efficacious levels of peroxycarboxylic acid concentrations in a solution produced in situ. The self-indicating chemistries include a combination of dyes providing a visual color indication, such as a tri-color indicator system, such as a yellow, green, and red color system indicating in situ threshold levels of peroxycarboxylic acid concentrations in a solution employing the self-indicating chemistry. Systems, kits and compositions for a quantitative assessment of an in situ perhydrolysis reaction to generate peroxycarboxylic acids are provided. Methods of use are further provided.
