Patent number: 11959045Abstract: The present invention is for an acidic cleaning composition which has excellent cleaning performance, low toxicity and good antimicrobial efficacy. The inventive acidic cleaning compositions are capable of sanitizing or disinfecting a variety of hard surfaces. The inventive acidic cleaning compositions can take a variety of forms, such as: disinfecting wipes, all-purpose disinfecting sprays, kitchen cleaners, bathroom cleaners, toilet cleaners, etc. The compositions may meet EPA DfE requirements, EPA category III or IV requirements, and/or be safe for use on food contact surfaces without rinsing. The compositions may include citric acid, an anionic surfactant, a non-volatile glycol solvent, a fatty acid, and water. The compositions may be free of other sanitizing acids, quaternary ammonium compounds, biguanides, peroxides, hypohalites, etc., and have a pH of less than 2.5. The composition may provide sanitization or disinfection against a target microbe within 5 minutes or less, or 4 minutes or less.Type: GrantFiled: August 19, 2021Date of Patent: April 16, 2024Assignee: THE CLOROX COMPANYInventors: Xuanrong Guo, Barbara Ekerdt, David R. Scheuing, Nancy A. Falk

Patent number: 11932833Abstract: Peroxide treatment compositions for use in laundry capable of providing sanitization through the wash e.g., for use with a detergent, where a peroxide activator is stabilized without the presence of phosphorus-containing compounds (e.g., phosphorus-containing stabilizers), through use of a nonionic surfactant (e.g., alkoxylated alcohol) with a cloud point above 45° C. Use of a single nonionic surfactant, or a surfactant package that may include a small fraction (e.g., less than 0.5%) of sodium lauryl sulfate or another anionic surfactant has been found to be surprisingly effective at stabilizing the peroxide/activator combination, even where water content may be 85% or greater. The composition can have a pH of 5 or less (e.g., 3 to 4). The composition may be free of other anionic surfactants, cationic surfactants, zwitterionic surfactants, amphoteric surfactants, magnesium salts, borates and boric acid, hydroxides, chelating agents, various amine oxides, ethoxylated amines, and the like.Type: GrantFiled: February 16, 2022Date of Patent: March 19, 2024Assignee: THE CLOROX COMPANYInventors: Nancy A.

Publication number: 20230301299Abstract: Cleaning compositions that include carvacrol, in an amount sufficient to provide an antimicrobial effect. For example, the compositions can include 0.1% to 2% by weight of carvacrol. The cleaning compositions advantageously further include a surfactant, particularly an anionic surfactant, which enhances the antimicrobial efficacy characteristics of the carvacrol. For example, the composition can include at least 0.1%, at least 0.3%, or at least 0.5% of one or more anionic surfactants. Alkyl sulfates (e.g., C8 to C12 alkyl sulfates) are particularly suitable. A buffer may also be present. The compositions may have a relatively high pH, e.g., 9 to 12. The cleaning composition may exhibit a significant log reduction against a target microorganism (e.g., Staphylococcus aureus and/or others) within a given time period (e.g., 10 minutes, 5 minutes, or the like), when used on a target surface.Type: ApplicationFiled: March 6, 2023Publication date: September 28, 2023Inventors: Nancy A.

Publication number: 20230078098Abstract: A pre-loaded cleaning substrate, and related systems and methods for picking up particles with an aspect ratio (L/D) greater than 300 (e.g., hair), or greater than 1200 (e.g., particularly long hairs). The substrate (e.g., a nonwoven) may include only a single layer of material. The pre-loaded substrate is loaded (e.g., during manufacture) with a cleaning composition. The fibers of the substrate may have an average diameter less than 15 ?m, the substrate may have an air permeability of 35 ft3/min to 75 ft3/min, and the liquid cleaning composition may have a surface tension of less than about 50 dynes/cm. Together, the combination of the particular substrate and cleaning composition may facilitate markedly improved ability to pick up high L/D aspect ratio particle debris (e.g., such as hair), while retaining such particles (e.g., providing hair retention index values of at least 20).Type: ApplicationFiled: November 15, 2022Publication date: March 16, 2023Inventors: Ashish K.

Publication number: 20230002703Abstract: Treatment compositions for use in laundry capable of providing sanitization through the wash e.g., for use with a detergent, where the compositions include an inorganic zinc salt potentiated by a phenolic solvent, to provide sanitization. The compositions can include an inorganic zinc salt, and a phenolic solvent, e.g., at an acidic pH (e.g., 2 to 5, or 3.5 to 4.5). The composition can include an anionic surfactant (e.g., alkyl sulfates, alkyl ether sulfates, etc.) and/or a nonionic surfactant (e.g., an alkyl polyglucoside). The composition may be free of alkoxylated nonionic surfactants which are not stable in the present compositions, which have high ionic strength (e.g., due to ˜3% of the zinc salt included in the formula). The composition may be free of various other components that would not be stable in such high ionic strength conditions, or otherwise interfere with stability and efficacy of the sanitizing and/or disinfecting laundry composition.Type: ApplicationFiled: April 8, 2022Publication date: January 5, 2023Inventors: Nancy A. FALK, Stephen F. GROSS, Shakera THAMANNA, Fanny FRAUSTO, Michael D. CAPRACOTTA, Dennys D. PENA CALDERON
