Mixture Comprising an Alkyl Polyglucoside, a Cosurfactant and a Polymer Additive

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

This patent describes a new mixture composed of an alkyl polyglucoside surfactant, a cosurfactant containing alcohol groups, and a specific polymer additive. When these are combined, the mixture can be used to create stable emulsions and microemulsions, especially with lower overall surfactant content. The invention is optimized for stability over a broad temperature range, is gentle on skin, reduces the need for hazardous solvents, and is suitable for a wide range of cleaning and formulation applications.

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

• Industrial and household cleaning agents, particularly as replacements for solvents in cleaners.
• Printing industry for cleaning printing presses, cylinders, and forms, especially for offset printing and removing ink, dust, and paper debris.
• Cosmetic products, where gentle and low-irritation emulsifiers are needed.
• Food industry applications requiring emulsions for safe and stable formulations.
• Pharmaceutical formulations where stable microemulsions are necessary for drug delivery or solubilization.
• Paintbrush and tool cleaning, especially for removing dried paints and varnishes from tools.
• All-purpose cleaners for sensitive surfaces such as aluminum, plastics, or coated metals.

BenefitsContent extracted from patent full text and abstract with AI.

• Enables production of stable emulsions and microemulsions at lower surfactant concentrations, making products safer and reducing environmental impact.
• Broad temperature stability window enhances practical utility and shelf-life of products.
• Reduces or eliminates the need for volatile organic solvents, improving safety and decreasing hazardous emissions.
• Gentle on skin and eyes, making it suitable for cosmetics, personal care, and food-related applications.
