Patent number: 10982177Abstract: Pre-moistened wipes that include one or more characteristics correlated to desired properties, such as high durability, mileage, cleaning composition retention, efficacy, or the like are described. Pulp substrates typically include an anionic charge, which can result in binding or retention of a cationic biocide such as a quaternary ammonium compound while the remainder of the composition is released from the wipe (e.g., through squeezing, wiping or other compression). The present wipes are specifically tailored to release at least 20% of the quaternary ammonium compound to a target surface, and exhibit at least a 3-log reduction in Staphylococcus aureus population within about 10 seconds to 5 minutes. Such release and efficacy is achieved without the presence of any cationic biocide release agent (e.g., latex or a cationic salt) included in the cleaning composition or elsewhere within the pre-loaded disinfecting wipe.Type: GrantFiled: April 24, 2018Date of Patent: April 20, 2021Assignee: THE CLOROX COMPANYInventor: Nikhil P.

Patent number: 10973385Abstract: Pre-moistened wipes that include one or more characteristics correlated to desired properties, such as high durability, mileage, cleaning composition retention, efficacy, or the like are described. Pulp substrates typically include an anionic charge, which can result in binding or retention of a cationic biocide such as a quaternary ammonium compound while the remainder of the composition is released from the wipe (e.g., through squeezing, wiping or other compression). The present wipes are specifically tailored to include a pore size distribution characterized by pores having a size from 300 ?m to 400 ?m, which is larger than the pore distribution characteristics of existing wipes. Such characteristics increase release of a quaternary ammonium compound to a target surface, providing improved microefficacy, without the need for any cationic biocide release agents such as latex or a cationic salt.Type: GrantFiled: July 16, 2018Date of Patent: April 13, 2021Assignee: THE CLOROX COMPANYInventor: Nikhil P.

Publication number: 20200198303Abstract: Multi-layer substrates comprising a top surface layer of pulp fibers, a bottom surface layer of pulp fibers, and a melted thermoplastic material layer between the pulp fiber layers, where the thermoplastic material comprises polyethylene or has a tan delta value of 0.2 to 0.4 within the temperature range of 100° F. to 350° F. The multi-layer substrate can include a cleaning composition loaded onto the multi-layer substrate, where a fluid pathway through the melted thermoplastic material allows the cleaning composition to travel from the top surface layer to the bottom surface layer. The multi-layer substrate may be void of chemical adhesives, where adhesion between the top surface layer and the thermoplastic layer, and between the bottom surface layer and the thermoplastic layer is instead provided by the thermoplastic material itself, which bonds to groups of fibers in the pulp fibers top and bottom surface layers that are in contact with the thermoplastic material as it melts.Type: ApplicationFiled: December 11, 2019Publication date: June 25, 2020Inventors: Nikhil P.

Publication number: 20200199824Abstract: Methods for forming multi-layer substrates comprising top and bottom surface layers and a melt softened thermoplastic material layer between the exterior surface layers, where the thermoplastic material comprises polyethylene or has a tan delta value of 0.2 to 0.4 within the temperature range of 100° F.-350° F. The 3 (or more) layers are assembled, and heated, melt softening the thermoplastic material, causing bonding of the thermoplastic layer to the exterior surface layers. A cleaning composition may finally be loaded onto the multi-layer substrate, where a fluid pathway through the melted thermoplastic material allows the cleaning composition to travel between the surface layers. Adhesion between the surface layers and the thermoplastic layer is provided by the thermoplastic material itself, which bonds to groups of fibers in the surface layers. The process does not require chemical adhesives, any processing water, drying, or the like, so as to be possible with low capital investment.Type: ApplicationFiled: December 11, 2019Publication date: June 25, 2020Inventors: Nikhil P.

Publication number: 20200087166Abstract: The invention relates to container bodies configured to be used in filter-as-you-pour systems, where filtering is achieved as the user pours water from the container. Such container bodies may have an undivided internal storage volume, so as to not include a reservoir compartment for unfiltered water. They may be part of systems configured to filter water both as water is introduced into a container body of the system and as water is poured from the container body of the system. The filter assembly may be attached to the container body at a location proximate the outlet of the system. Filter media of the filter assembly may comprise an activated carbon textile material that presents a curved surface to water passing through the filter assembly. The container body may be configured as a pitcher, carafe, water bottle, jug, or other shaped container.Type: ApplicationFiled: November 18, 2019Publication date: March 19, 2020Inventors: Nikhil P.

Publication number: 20200080031Abstract: Pre-moistened multi-layer wipes in which the fibrous substrate for the wipes comprises 70% or more pulp fibers. The present wipes are specifically tailored to include multiple layers that are adhered to one another with a water-resistant adhesive, e.g., which will maintain good peel strength, even when the multi-layer substrate is loaded with a cleaning composition during manufacture, and stored in such condition for an extended period (e.g., a shelf life of a year or more). The water-resistant adhesive may specifically comprise a ethylene vinyl acetate (e.g., rather than polyvinyl alcohol or other adhesives which do not adequately maintain peel strength), loaded between the layers of the substrate, e.g., up to 10 gsm. The wipe may have a peel strength of at least from 0.15 lbf-in, even after being soaked in the cleaning composition. Such pulp substrate wipes are formed from sustainable materials, while providing desired characteristics of strength and efficacy.Type: ApplicationFiled: August 27, 2019Publication date: March 12, 2020Inventors: Nikhil P.

Publication number: 20200040496Abstract: Methods for manufacturing wipes including melamine entangled into a nonwoven, and associated articles of manufacture. Such a method may include providing a melamine sheet (e.g., contiguous, rather than discrete melamine particles), providing first and second nonwoven sheets, and positioning the melamine sheet between the first and second nonwoven sheets. The sandwich structure is hydro-entangled at high pressure to force the melamine material to become entangled into the nonwoven material, to a degree that a portion of the melamine is actually exposed on the exterior face(s) of the wipe, which are generally provided by the nonwoven sheets. Such a wipe exhibits the drapability of a wipe, with the scrubbing benefits (e.g., very effective cleaning of baseboards, crayon off walls, etc.) of melamine, with greater durability than existing melamine cleaning articles, which tend to quickly crumble during use.Type: ApplicationFiled: October 15, 2019Publication date: February 6, 2020Inventor: Nikhil P. Dani
