  • Patent number: 11639553
    Abstract: Disclosed herein are corrosion control compositions comprising one or more multiple charged cationic compounds to reduce corrosion of metal surfaces in a water system. The multiple charged cationic compounds are derived from polyamines through a ring-opening reaction with an epoxide or two reactions: an aza-Michael addition with an activated olefin having a cation group and a ring-opening reaction with an epoxide. The disclosed compositions are found to be effective corrosion inhibitors for water systems.

  • Patent number: 11590065
    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: 11572531
    Abstract: The invention includes ware detergent compositions which provides superior cleaning and removal of oily and fatty soils, without the production of excessive foam. According to the invention applicants have discovered that use of a quaternary cationic surfactant in combination with a nonionic low foaming surfactant can provide oily soil removal from ware that is superior to traditional warewash detergent formulations. Compositions for alkaline, preferably solid, warewash detergents are disclosed, as well as their use in dish machines and methods of manufacture.

  • Patent number: 11565958
    Abstract: Disclosed herein are the methods of using di-cationic or di-anionic compounds, which are derived from primary amine through an aza-Michael addition with an activated olefin, in a corrosion control composition to mitigate corrosion of a surface in a water system. The disclosed methods or compositions are found to be more effective than those methods or compositions including commonly used single quaternary compounds for mitigating corrosion for a metal surface in water systems.

  • Publication number: 20220372410
    Abstract: Caustic-free detergent compositions are provided. Detergent compositions including an aminocarboxylate, water conditioning agent, non-caustic source of alkalinity and water beneficially do not require the use of additional surfactants and/or polymers to provide suitable detergency and prevent scale build-up on treated surfaces and enhance protein removal from the treated surfaces. Beneficially the detergent compositions have a concentrate pH less than about 11.5. The detergent compositions are used with a sanitizer to employ the low alkaline detergent compositions are particularly suitable for use as low temperature ware wash detergents that beneficially reduce scale build-up. Methods of employing the low alkaline detergent compositions are also provided.

  • Publication number: 20220372405
    Abstract: Solid detergent compositions designed to maintain solid integrity throughout production of the pressed solid, during mechanical conveying and during ejection from molds, are disclosed. Solid detergent compositions having unexpected immediate block hardness without a curing step are provided by inclusion of a hardness additive composition comprising a synergistic ratio of polycarboxylic acid polymer chelants to aminocarboxylate chelants. Methods of making solid detergent compositions and solid detergent compositions having at least substantially similar cleaning performance to solid detergent compositions without the hardness additive composition are also provided.
