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.

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). The use of the high alkaline cleaner of the present invention has demonstrated enhanced cleaning characteristics especially at higher temperatures (100° F. to about 300° F.) but also shows enhanced cleaning at ambient temperatures.

A decontamination paste comprising at least one inorganic viscosifier selected from clays, at least one compound in the form of fibers and optionally further one or more optional components, the remainder being of solvent. A method for decontaminating a substrate made of a solid material using the paste, the substrate being contaminated by at least one contaminant species referred to as the labile contaminant species and/or by at least one contaminant species referred to as the surface contaminant species located on one of the surfaces thereof, and/or by at least one contaminant species referred to as the subsurface contaminating species located just below said surface, and/or by at least one contaminant species located under the surface in the depth of the substrate.

The disclosure relates to a silica-based structurant and methods of making such a structurant. According to one embodiment, the structurant may include 55 wt % to 90 wt % of a silica having a [Na.sub.2O]/[SiO.sub.2] molar ratio of from 0.02 to 0.14 and at least 15 wt % of an adjunct salt. The structurant may have a hydrated particle size distribution such that no more than 30 wt % of the structurant has a hydrated particle size greater than 45 micrometers according to the Structurant Residue Test. The structurant may also have a tapped bulk density of from 200 g/L to 300 g/L. Methods of making the structurant include combining starting materials with a non-stoichiometric amount of acid, then drying the reaction mixture without first washing any silica-based particles to produce a silica-based structurant with adjunct salt.

Caustic-free detergent compositions are provided. Detergent compositions including an aminocarboxylate, water conditioning agent, non-caustic source of alkalinity and water beneficially do not require the use of additional surfactants and/or polymers to provide suitable detergency and prevent scale build-up on treated surfaces and enhance protein removal from the treated surfaces. Beneficially the detergent compositions have a concentrate pH less than about 11.5. The detergent compositions are used with a sanitizer to employ the low alkaline detergent compositions are particularly suitable for use as low temperature ware wash detergents that beneficially reduce scale build-up. Methods of employing the low alkaline detergent compositions are also provided.
