  • Publication number: 20210071110
    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.

  • Publication number: 20200407544
    Abstract: Stable solid compositions employing a water conditioning agent, including hygroscopic species or non-hygroscopic species. In particular, solid compositions combining an ionic surfactant or an amphoteric surfactant with a water conditioning agent, preferably a polyacrylate water conditioning agent, are disclosed. The ionic surfactant or amphoteric surfactant beneficially stabilize the polymer and/or chelant water conditioning agent, preferably a polyacrylate water conditioning agent, to permit formulation into a solid composition and provide stability under harsh conditions, including humid environments. Applications of using the stable solid compositions are also disclosed.
