    摘要: Pre-dosed wipes and packaged systems of such wipes including a nonwoven substrate formed from renewable natural plant-based fibers or derivatives of such fibers. The pre-dosed wipe as a whole meets applicable biodegradability/compostability standards (e.g., ASTM D6400, EN13432 or the like). The wipe may be a sanitizing or disinfecting wipe, including a quaternary ammonium compound as an antimicrobial agent in the composition with which the substrate is dosed. The composition may also include water and a surfactant. The wipe may be substantially void of thermoplastic fibers, such as PE, PP, PET, as well as so-called biodegradable polyesters and the like (e.g., PHA, PLA, PVOH). The nonwoven substrate may be formed by any of various techniques, an example of which is spunlace. The formulation may have a pH of at least 5 (e.g., 6 to 8), to maintain tensile strength of the natural plant-based substrate.

    摘要: 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 μm, 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).

    摘要: The present invention is for sanitizing compositions for sanitizing surfaces which may contact food. The composition may be provided in liquid form, and may include a quaternary amine, one or more surfactant, a fragrance, and water. At least 90% by weight of the fragrance comprises fragrance components that meet Class I qualifications of the Cramer classification system. All other components of the composition (e.g., the quaternary amine, the surfactants, water, and any optional components) meet the EPA guidelines under CFR 180.940(a). Since the composition only includes components that meet the EPA guidelines under CFR 180.940(a) (reflecting a presumption of low toxicity), and at least 90% of the fragrance itself (e.g., in the case of mixtures of fragrance components) meets the Cramer Class I qualifications, the composition is safe for application to surfaces that come in contact with food, where there is a heightened probability that traces of the composition will be ingested.

    摘要: A self-contained system for grilling including a non-combustible tray, a mesh insert within the tray, defining an air-flow portion below the insert, and a fuel portion above the insert for supporting fuel (e.g., charcoal briquets), with the fuel suspended above the air-flow portion. A plurality of holes may or may not be provided through a lower portion of the tray (e.g., in a lower portion of the sidewall of the tray) to draw combustion air into the air flow portion, below the mesh insert. The system may pre-arrange the fuel in the tray during manufacture, so the user is not required to spread or even touch the briquets, or may be for use with fuel provided by a user. Clean up is very simple, as the entire system can be discarded after a single use, once cooled, as the ash is automatically collected in the bottom of the tray.
