摘要:
A method for antimicrobial treatment comprising applying to microbes a composition containing a diluting solvent (e.g., water), an antimicrobially-active solvent having a density different from the density of the diluting solvent, and an optional cosolvent, surfactant, or additional antimicrobial agent, wherein the amount of antimicrobially-active solvent or additional antimicrobial agent is sufficiently high and the amount of cosolvent or surfactant is sufficiently low so that the composition will provide greater than a 1-log order reduction in the population of bacteria or spores of Bacillus cereus within 10 seconds at 60° C. Preferred methods of the invention employ compositions containing an additional antimicrobial agent such as peroxyacetic acid. Compositions for use in the method can be prepared as concentrates, and used full strength or in diluted form.
摘要:
The ability of aqueous laundry compositions to remove organic hydrophobic soils, such as oily, greasy or particulate soils, from a laundry item is substantially improved by pre-spotting or pre-treating such a soiled item with a treatment composition having a surfactant comprising a unique hydrophillic ethoxylate surfactant with less than two moles of ethylene oxide or a or blend of at least two surfactant compositions with a blended HLB value of about 7-12. The blend of surfactants with this HLB value penetrates soils and renders the soil more easily removed from the item using aqueous laundry detergent. The treatment composition can be used in a liquid or solid form and can be applied to individual laundry items in the form of a solid stick or liquid spray prior to introduction to the laundry machine. Laundry items can also be contacted in the laundry machine with the pre-spot or pre-treatment composition in the form of an aqueous presoak, preflush, prewash, or other step prior to the cleaning step. A preferred laundry machine comprises an institutional tunnel washer.
摘要:
The present disclosure provides methods for generating percarboxylic acid compositions and/or peroxycarboxylic acid compositions formed external to a point of use in non-equilibrium reactions for use in certain bleaching and antimicrobial applications, in particular laundry applications. The compositions are generated external to a point of use, at alkaline pH levels, viz. greater than about pH 12, and optionally suitable for use with detergents and/or surfactants for synergistic bleaching efficacy. Methods of bleaching and/or disinfecting are further provided.

Disclosed are concentrated liquid rinse cycle fabric softener compositions comprising a quaternary ammonium cation and benzylated alcohol solvent having between 50% to 90% weight active ingredients. Benzyl alcohol is disclosed as a preferred solvent to produce a clear liquid solution formulation rather than emulsion. The concentrated liquid rinse cycle fabric softener compositions of the present invention possess desirable stability, sustainability and fabric-softening properties. Methods of use are further described.
摘要:
Floor finishes are stripped or deep scrubbed using a floor stripper/cleaner composition containing sparingly water-soluble floor finish solvent; water; sulfonic acid, sulfate acid, phosphonic acid, phosphate acid or aromatic acid coupler in an amount sufficient to provide a homogenous aqueous liquid phase and no or low foaming during shaking; and sufficient organic amine so that the composition pH is about 2 to about 11.

A method for treating a separation facility is provided according to the invention. The separation facility includes a plurality of membranes for providing separation of a feed product. The method includes steps of providing liquid flow through a plurality of membranes; treating the plurality of membranes with a multiple phase treatment composition comprising a gaseous phase and a liquid phase at a volumetric ratio of the gaseous phase to the liquid phase of at least about 5:1; and providing a liquid flow through the plurality of membranes.
摘要:
The present invention relates to antimicrobial compositions including a critical, near critical, or supercritical (densified) fluid and an antimicrobial agent, to methods of forming these compositions, and to methods employing these compositions. An antimicrobial agent can be generated in the presence of a densified fluid, for example, by reacting an oxidizing agent with a precursor to the antimicrobial agent.
摘要:
Continuous coatings including floor finishes can be prepared using novel two part compositions and methods. The two part compositions comprise a solid particulate polymer part and a liquid coalescing agent part. A novel method of the invention involves contacting the coalescing agent with the polymer in a variety of coating methods including applying the polymer to the coalescing agent, applying the coalescing agent to the polymer or applying the coalescing agent and polymer simultaneously. The polymer and coalescing agent interact to form a continuous coating layer or finish layer.
摘要:
Disclosed is a process for the treatment of a plant fluid effluent containing odor compounds including an alkyl mercaptan or an alkyl thiol, an amine compound, ammonia, hydrogen sulfide and mixtures thereof by contacting the plant effluent in either a counterflow or cocurrent flow process. In the process, the effluent is contacted with an aqueous solution comprising a peroxyacid compound and one or more essential oils. When contacted with the peroxyacid, odor compounds in the effluent are oxidized and converted from the gaseous phase into a chemically modified highly aqueous soluble phase in the aqueous treatment. In this way, odor removal from the gas is preferred and odor compounds are efficiently transferred into the aqueous treatment solution. The use of such a process produces a significant improvement in odor quality index as measured by a conventional process using an expert panel when compared to conventional treatment methods.
摘要:
The present invention relates to novel combined laundry detergent, bleach, and antimicrobial composition incorporating novel sulfoperoxycarboxylic acid compounds, and methods for making and using them. The sulfoperoxycarboxylic compounds used in compositions of the invention are storage stable, water soluble and have low to no odor. Compositions of the invention may be in the form of a liquid, a solid, or a gel. The sulfoperoxycarboxylic compounds useful in preparing compositions of the present invention can be formed from non-petroleum based renewable materials.
