  • Patent number: 11697787
    Abstract: The present disclosure relates to high alkaline cleaners, cleaning systems and methods for removing polymerized zero trans fat soils. The high alkaline cleaner of the present invention generally includes one or more alkaline wetting and saponifying agent(s), a chelating/sequestering system and a surface modifying-threshold agent system. In various embodiments, the cleaners may include, at least one cleaning agent comprising a surfactant or surfactant system and/or a solvent or solvent system and/or a cleaning booster such as a peroxide or sulfite type additive. The cleaners may also include one or more components to modify the composition form and/or the application method in some embodiments. All components described above may also be optimized optionally, to provide emulsification of a composition (both as a usable product or a concentrate that can be diluted to form a usable product).

  • Patent number: 11236291
    Abstract: The present invention comprises chlorinated and non-chlorinated alkaline cleaning compositions for removal of proteinaceous and fatty soils at low temperature, i.e. less than 120° F., with little or no deleterious affect on cleaning performance. According to the invention, applicants have found that adding additional alkalinity makes protein removal more difficult and reducing the amount of alkalinity actually improves performance. According to the invention optimized combinations of chlorine and alkalinity components for low temperature cleaning as well as a surfactant system optimized for low temperature fatty soil removal are disclosed.
