Microemulsion-Based Cleaning Agent

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

This patent describes a novel aqueous cleaning agent based on microemulsions. The cleaning agent contains a mix of carboxylic acid esters (oils), water-soluble salts (such as sodium or calcium salts), salts and acids of monocarboxylic acids (like fatty acids and their salts), and special booster additives. The formulation is designed to be environmentally and skin-friendly, highly stable over a wide temperature range, low in surfactant content, and effective at removing tough stains, especially paints, oils, resins, adhesives, and other polymer-based contaminants. Uniquely, the product is essentially free from traditional harsh solvents and is often neutral in pH, making it suitable for sensitive surfaces and for consumer as well as industrial use.

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

• Removal of tough or dried paint residues from brushes, rollers, spray guns, and surfaces.
• Cleaning of adhesive, resin, or polymer-based contamination on metal, plastic, or household surfaces.
• Household and commercial use as an all-purpose or neutral cleaner for kitchens, ovens, grills, fireplaces, and sensitive surfaces like aluminum.
• Industrial cleaning for machinery maintenance and removal of oils, greases, and other persistent dirt without damaging materials.
• Safe cleaning in environments requiring low VOC (volatile organic compound) emissions, such as food processing or healthcare settings.
• Replacement for solvent-based cleaners in art studios, construction, and automotive maintenance.

BenefitsContent extracted from patent full text and abstract with AI.

• Environmentally-friendly: avoids hazardous solvents and reduces VOC emissions.
• Skin-friendly: leaves a pleasant feel on the skin and is less likely to cause irritation compared to traditional strong cleaners.
• Wide temperature stability: effective and stable over a broad temperature range, ensuring safe storage and use.
• Highly effective cleaning: removes both water-based and oil-based contaminants, including dried paints and polymeric materials.
• Low odor: largely odorless compared to strong-smelling conventional cleaners.
• Reduced health and safety risks: lower flammability, less aggressive to user health and surfaces.
• Easily rinsed with water: cleaning agent and residues can be washed away with water, leaving minimal trace.
• Suitable for sensitive materials: can be used on substrates that could be damaged by high alkalinity or strong solvents.
