  • ENZYMATIC CAUSTIC FREE DETERGENT COMPOSITIONS FOR CLEANING DAIRY PROCESSING SYSTEMS
    Publication number: 20260125615
    Abstract: The disclosure relates to enzymatic caustic-free detergent compositions for cleaning dairy processing surfaces (such as dairy CIP and dairy COP systems and their components). Also disclosed are methods of making and using the detergent compositions to beneficially remove fouling and clean the surfaces utilized in dairy production. The enzymatic caustic-free detergent compositions preferably comprise an enzyme, a surfactant, a water conditioning agent, a C2-C10 polyol, a buffer system, a salt, and water.

  • Reducing agent as corrosion inhibitor for neutral or low alkaline warewash detergent
    Patent number: 12612579
    Abstract: Warewash detergent compositions with reducing agents to overcome corrosion challenges in stainless steel dish machines subject to conditions from chlorine sanitizing rinse steps (or other oxidizing chlorine containing compositions) are provided. Detergent compositions or booster compositions used in combination with detergents beneficially containing a reducing agent that reacts with chlorine introduced in sanitizing rinse steps that follow detergent cleaning steps are provided. Methods for ware washing using the detergent compositions with reducing agents and methods for reducing residual chlorine in a ware washing cycle are also provided.
