Active Agents Improving Primary Washing Power

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

This invention relates to the use of specialized macrocyclic compounds, specifically sulfonated or carboxylated calixarenes modified with alkoxy groups, as additives in detergents and cleaning agents. These compounds improve the initial (primary) cleaning power of detergents, particularly on stains that are sensitive to bleach or enzymes, such as those found on textiles and hard surfaces. The invention covers formulations, methods, and the synthesized calixarene compounds that, when integrated into detergent products, enhance their performance, even at low temperatures.

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

• Laundry detergents for household or industrial use, especially for removing tough stains from clothes, including enzyme- or bleach-sensitive soils.
• Dishwashing detergents, both for hand-washing and in dishwashers, to improve removal of stubborn residues from tableware and utensils.
• Surface cleaning agents used on hard surfaces such as floors, tiles, or countertops, providing better stain removal.
• Specialty cleaning products for healthcare, hospitality, or food service sectors where superior stain removal is required at low temperatures.
• Formulations for delicate fabrics or colored textiles where mild yet effective cleaning is crucial.

BenefitsContent extracted from patent full text and abstract with AI.

• Significantly improves the effectiveness of detergents against challenging stains that are sensitive to bleach or enzymes.
• Allows for effective cleaning at lower washing temperatures, thus saving energy and protecting delicate textiles.
• Enables reduction of surfactant (detergent) quantities needed, contributing to more eco-friendly formulations.
• Enhances compatibility and synergetic effects with common detergent ingredients like surfactants, bleaches, and enzymes.
• Potential for improved cleaning performance in both manual and machine washing or dishwashing applications.
• Helps maintain the brightness and appearance of textiles by more effectively removing stains.

Patent Abstract

The aim of the invention is to improve the primary detergent power of detergents and cleaning agents, in particular with respect to bleach or enzyme-sensitive soiling. This is substantially achieved by the incorporation of alkoxy group-supporting sulfocalixarenes or carboxycalixarenes.
