摘要:
The invention includes compositions and methods for sanitizing ware without staining, spotting or corroding. In its most preferred mode, the method comprises the steps of washing the ware in an automated ware washing machine and rinsing the ware at either high or low temperatures with a sanitizing rinse composition. The destaining, sanitizing concentrate composition preferably comprises peroxyacetic acid, acetic acid, and hydrogen peroxide using higher levels of acetic and peroxyacetic acid and a lower level of hydrogen peroxide. The sanitizing rinse composition may preferably be used at a concentration of peroxyacetic acid of at least 30 ppm.

In its most preferred mode, the method comprises the steps of washing the ware in an automated ware washing machine and rinsing the ware at either high or low temperatures with a sanitizing rinse composition. The destaining, sanitizing concentrate composition preferably comprises peroxy acetic acid, acetic acid, and hydrogen peroxide. The sanitizing rinse composition may preferably be used at a concentration ranging from about 600 ppm to 4000 ppm.

A method of sanitizing and destaining ware, including silverware includes the steps of applying a sanitizing concentrate composition to silverware at a rate of 100 ppm to 2000 ppm, the sanitizing concentrate composition including from about 1 wt-% to 20 wt-% of peroxycarboxylic acid, from about 10 wt-% to 50 wt-% of carboxylic acid containing a mixture of acetic acid, and octanoic acid, the acetic acid and the octanoic acid present in a ratio ranging from about 10 to 1 to about 1 to 1, respectively, from about 3 wt-% to 35 wt-% of hydrogen peroxide, and a balance of carrier wherein said peroxycarboxylic acid is the reaction product of the acetic acid, octanoic acid, and hydrogen peroxide.
摘要:
A peroxyacid antimicrobial concentrate and use composition is provided comprising a C.sub.5 peroxyacid in combination with a C.sub.1 -C.sub.4 peroxyacid, a C.sub.6 -C.sub.18 peroxyacid, or mixtures thereof. The combination of these peracids 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. Sanitizing of substantially fixed, "in-place" processing lines in dairies, breweries, and other food processing operations is one utility of the composition.
摘要:
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.

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.

摘要:
Compositions for use as soil removing agents in the food processing industry are disclosed. Food soiled surfaces in food manufacturing and preparation areas can be cleaned. The compositions are manufactured in the form of a concentrate which is diluted with water and used. The cleaning materials are made in a two part system which are diluted with a diluent source and mixed prior to use. The products contain high quality cleaning compositions and use a variety of active ingredients. The preferred materials, in a two part system contain detergent compositions, enzymes that degrade food compositions, surfactants, low alkaline builders, water conditioning (softening) agents, and optionally a variety of formulary adjuvants depending on product form.
摘要:
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.
