  • Publication number: 20140335199
    Abstract: Peracid stable fluorescent active compounds in highly acidic, equilibrium peroxycarboxylic acid sanitizing compositions are disclosed as having improved fluorescent stability allowing for monitoring of peroxycarboxylic acid concentration by conductivity and/or optical sensors. Beneficially, the compositions are also low odor and low/no VOC dual functioning acid wash and sanitizing compositions.

  • Publication number: 20140308162
    Abstract: 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.

  • Publication number: 20140238445
    Abstract: Methods employing detergent compositions comprising phosphinosuccinic acid oligomers (PSO) in combination with a sanitizing rinse aid are disclosed. The methods beneficially clean, sanitize and rinse a surface in an efficient two-step process. The detergent compositions employ phosphinosuccinic acid adducts, namely mono-, bis- and oligomeric phosphinosuccinic acid (PSO) derivatives, in combination with an alkalinity source and optionally polymers and/or surfactants. The sanitizing and rinsing compositions employ peroxycarboxylic acid compositions in combination with a nonionic defoaming and wetting surfactant.
