Abstract: The invention is a method of removing soils containing oils and fats from food processing surfaces. The method includes the steps of formulating a wash composition from a two-part concentrate. The concentrate first part includes a source of alkalinity and water. The concentrate second part includes a quaternary ammonium compound. After formulation, the wash composition has a major portion of water, from about 100 ppm to 20,000 ppm of quaternary ammonium compound, and an alkali source present in a concentration to provide a pH of from about 10 to 14. After formulation, the wash composition may be used by applying it to the food processing surface. Optionally, the wash composition may also include a chelating agent and a second nonionic or anionic detersive agent.

Abstract: A peroxyacid antimicrobial concentrate and use composition is provided comprising a C.sub.1 to C.sub.4 peroxycarboxylic acid, and a C.sub.6 to C.sub.18 peroxyacid. The combination of these acids produces a synergistic effect, providing a much more potent biocide than can be obtained by using these components separately. Other components can be added to the composition such as hydrotrope coupling agents, stabilizers, etc. An effective antimicrobial use solution is formed at low concentrations when the concentrate composition is diluted with water to a pH in the range of about 2 to 8. Sanitizing of substantially fixed, "in-place" processing lines in dairies, breweries, and other food processing operations is one utility of the composition.

Other components can be added to the composition such as hydrotrope coupling agents, stabilizers, etc. An effective antimicrobial use solution is formed at low concentrations when the concentrate composition is diluted with water.

Abstract: A pH greater than 7 aqueous ozonized cleaning composition can be used for cleaning a tenacious residue or film from solid surfaces. The cleaning properties can be potentiated by additive materials. Ozone, generated by electrical discharge, can be blended into effective aqueous cleaning compositions that can efficiently clean proteinaceous, oily or carbohydrate soil from a variety of surfaces. Immediately after ozone generation, the ozone containing gas stream comprising ozone and the residual air is injected through a hose into an aqueous potentiating additive containing carrier solution, forming a cleaning solution which is applied immediately to a soiled solid surface to remove a contaminating residue or film.

Abstract: We have found a new and useful process to generate peroxy acid sanitizing and bleaching compositions at the point-of-use, the process comprising introducing hydrogen peroxide and a carboxylic acid into a reactor at about 0.1 to 10 moles of hydrogen peroxide per mole of acid, and contacting the hydrogen peroxide and carboxylic acid in the presence of a sulfonic acid resin and in the substantial abssence of active metal ions which forms an aqueous peroxy acid composition at a concentration from about up to 20 wt %. Using this process, warewashing, laundry sanitizing and bleach, and hard surface sanitizing compositions can be produced.

Abstract: Washing methods of deinking secondary cellulose fiber (i.e., removing unwanted non-cellulose materials therefrom) are disclosed. These washing methods (as opposed to flotation methods) generally involve deinking the fiber with surface active agent (surfactant).The present invention utilizes a single foam-suppressing surface active agent consisting essentially ofR--(Ar)--(OC.sub.2 H.sub.4)m--(OC.sub.3 H.sub.6)n--Y;wherein R represents a monovalent higher aliphatic group containing from 6 to 24 carbon atoms,Ar represents an aromatic residue,--(OC.sub.2 H.sub.4)m--being a poly(ethylene oxide) chain,--(OC.sub.3 H.sub.6)n--being a poly(propylene oxide) chain;m is about 6 to about 15,n is about 12 to about 48,m:n is less than 1, andY is selected from the group consisting of hydroxyl and benzyl ether.The present washing method of deinking reduces or eliminates objectionable foam, potentially provides energy savings yet maintains or improves the quality of the deinked fiber.
