Bleaching Washing or Cleaning Agent

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention relates to the use of specific metal-carbene complexes as catalysts to boost the bleaching and oxidation power of peroxygen compounds (such as hydrogen peroxide, sodium percarbonate, or perborate) at low temperatures (10 °C - 45 °C). By incorporating these metal-carbene complexes into washing, cleaning, or disinfecting agents, the bleaching effectiveness is significantly enhanced even during cold or low-temperature washes, improving stain removal from textiles and hard surfaces.

Use CasesContent extracted from patent full text and abstract with AI.

• Laundry detergents for washing textiles at low or cold temperatures with improved stain and color removal.
• Dishwashing detergents or cleaners for hard surfaces to enhance the removal of colored stains (like tea) without the need for high temperatures.
• Formulation of household or industrial cleaning agents that are energy-efficient due to their effectiveness at lower temperatures.
• Disinfectants requiring enhanced oxidation/bleaching activity to improve hygiene and sanitation.
• Pulp or textile processing, where bleaching at low temperatures is desirable to reduce energy costs.

BenefitsContent extracted from patent full text and abstract with AI.

• Enables effective bleaching and stain removal even at low water temperatures, reducing the need for energy-intensive hot washes.
• Improves the overall cleaning performance of detergents, including removal of stubborn stains like fruit or tea.
• Allows for more energy-efficient washing and cleaning processes, contributing to environmental sustainability and lower utility costs.
• Expands the applicability of peroxygen-based cleaning systems to situations where high water temperatures cannot be used or are undesirable (e.g., delicate fabrics).
• Provides broad compatibility with standard detergent ingredients and formulations.
