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

The present invention relates generally to peroxyformic acid forming compositions, methods for forming peroxyformic acid, preferably in situ, using the peroxyformic acid forming compositions. The present invention also relates to the peroxyformic acid formed by the above compositions and methods. The present invention further relates to the uses of the peroxyformic acid, preferably in situ, for treating a surface or a target. The present invention further relates to methods for treating a biofilm using peroxyformic acid, including peroxyformic acid generated in situ.

Generation of peroxyformic acid through polyhydric alcohol formate

Anti-microbial compositions comprising (a) a quaternary ammonium compound and (b) a cationic biocide. Applicant has discovered a synergistic combination of the two components with the ration of cationic biocide to quaternary ammonium being less than 1:10 or with a single quaternary compound in a ratio of less than 1.6 to 1 provide a film forming coating that has residual anti-bacterial activity and improved durability with strong resistance to general wear between applications.

Wear resistant antimicrobial compositions and methods of use

Methods and compositions for biofilm remediation are disclosed. Biofilm is reduced and removed from soiled surfaces by providing to a surface in need an effective amount of a composition comprising a biocidal surfactant and at least one organic solvent. According to the invention, the biofilm remediation compositions reduce and remove biofilm formation by administering a one-step cleaner and disinfectant. The biofilm remediation compositions are stable and effective in concentrated and diluted ready-to-use formulations comprising an anionic sulfated or sulfonated surfactant that is not an organocarboxylic acid, a sparingly soluble organic solvent and optionally a soluble organic solvent.

Acidic biofilm remediation

Peroxyformic acid compositions for treatment and removal of biofilm growth and mineral deposits on membranes for energy services applications are disclosed. In particular, peroxyformic acid compositions are generated in situ or on site generation for the reduction and prevention, of biofilms and the mitigation of mineral buildup on the membranes. The compositions according to the invention are compatible with the membranes under application of use conditions.

Peroxyformic acid compositions for membrane filtration cleaning in energy services

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.

Generation of peroxyhydroxycarboxylic acid and the use thereof

A concentrated liquid sanitizing and rinse composition containing peroxycarboxylic acid(s) and compatible rinse aid surfactants is disclosed. The sanitizing and rinsing compositions are formulated in a single liquid concentrate, replacing a traditional dual product of a sanitizer and rinse aid. The sanitizing and rinsing chemistries are particularly effective at neutral pHs against gram negative organisms at elevated temperatures. Methods of using the concentrated liquid sanitizing and rinse composition are also disclosed.

Peroxycarboxylic acid based sanitizing rinse additives for use in ware washing

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

Peroxyformic acid compositions for removal of biofilm growth and mineral deposits on membranes are disclosed. In particular, peroxyformic acid compositions are generated in situ or on site generation for the reduction and prevention, of biofilms and the mitigation of mineral buildup on the membranes. The compositions according to the invention are compatible with the membranes under application of use conditions.
