  • Patent number: 12146120
    Abstract: Cleaning and degreasing compositions containing a diutan gum thickener are provided for removing burnt on, polymerized, carbonized food soils with minimum manual effort. The compositions are ready to use compositions and beneficially remain on a treated surface for sufficient time to permit soil penetration without drying out. The compositions can be easily removed with minimal manual effort, such as use of low pressure water applied to the treated surface, and beneficially do not leave residues. Methods for cleaning and degreasing a surface with the compositions are also provided. Thickening systems employing the diutan gum and laponite clays are also provided.

  • Publication number: 20240076578
    Abstract: Alkaline sprayable aqueous compositions for cleaning, sanitizing and disinfecting are disclosed. In particular, the sprayable compositions include an alkali soluble emulsion polymer, an alkalinity source, a foaming agent, and water. Beneficially, the sprayable cleaning compoistions have reduced misting and are environmentally safe for users to apply. Further the compositions exhibit less running on non-horizontal surfaces than acrylamide-based compositions.

  • Publication number: 20230157937
    Abstract: The antimicrobial composition of the present invention comprises a cationic active ingredient, a foam boosting surfactant, a foam boosting copolymer, a foam stabilizer, and a chelating agent. The present antimicrobial compositions are free of the antimicrobial agent triclosan (i.e., 2,4,4?-trichloro-2?hydroxy-diphenylether), have rapid cidal activity, provide stable copious foam and exhibit enhanced tissue (e.g. skin) compatibility as defined by an in vitro whole toxicology assessment method.

  • Patent number: 11603510
    Abstract: A solid hard surface cleaning composition suitable for replacing liquid formulations while providing at least equivalent or enhanced cleaning performance, including at lower concentrations, is provided. The solid hard surface cleaning compositions include alkali metal carbonate alkalinity source(s), aminocarboxylic acid chelant(s), amphoteric surfactant(s), polyacrylate polymer(s) and anionic surfactant(s). The solid hard surface cleaning compositions can include additional functional ingredients, such as corrosion inhibitors. The solid hard surface cleaning compositions do not include hydroxide alkalinity and beneficially provide stable ready-to-use formulations that are safe for contact without the use of personal protective equipment (PPE) and are compatible with soft metals.
