Universal Cleaning Paste Formulation for Stain Removal and Skin Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning agents often require knowledge of the stain type, are not universally applicable, and can be aggressive, posing risks to both surfaces and skin health, especially when cleaning colored materials.
Innovation Solution
A cleaning paste composition comprising 35-45% gasoline fractions, 15-25% oleic acid methyltaurine or its salts, 5-20% ethoxylated fatty alcohols, and 15-25% alkali metal dithionite, along with optional surfactants and inorganic salts, which forms a paste with excellent cleaning performance and skin compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If special cleaning agents for specific stain types are used, then cleaning effectiveness is improved, but the complexity of selection and knowledge required increases
Solution Approach 1:
The patent applies universality by formulating a single cleaning paste composition that effectively removes multiple types of stains (fruit stains, iodine, ink, grease, etc.) through a combination of surfactants and solvents. This multi-functional formulation eliminates the need for users to identify specific stain types and select different products, thereby resolving the contradiction between cleaning effectiveness and ease of selection.
2Reliability
If aggressive cleaning agents are used, then cleaning performance is improved, but skin compatibility and material safety deteriorate
Solution Approach 1:
The patent applies composite materials by combining multiple gentler components (anionic surfactants, nonionic surfactants, maleic acid-acrylic acid copolymer, phosphates, and various solvents) to achieve effective cleaning performance without the need for harsh aggressive agents. This composite formulation maintains cleaning efficacy while improving skin compatibility and reducing harmful effects on cleaned materials.
3Reliability
If high concentration of active cleaning components are used, then cleaning efficacy is improved, but skin irritation and harmful effects increase
Solution Approach 1:
The patent applies parameter changes by optimizing the concentration ranges of multiple components rather than using high concentrations of single active ingredients. The formulation specifies precise ranges: anionic surfactants (4.0-15.0%), nonionic surfactants (20.0-40.0%), maleic acid-acrylic acid copolymer (0.5-1.5%), phosphates (2.0-10.0%), and various solvents. This balanced parameter optimization achieves effective cleaning while minimizing skin irritation and harmful effects.
