Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning compositions with lipases face challenges in effectively removing lipid stains due to interference from other active ingredients, necessitating improved formulations for enhanced cleaning and wash performance.
Innovation Solution
A detergent composition comprising surfactants, sodium carbonate, sodium sulfate, and a lipase derived from Thermomyces lanuginosus, with specific modifications to enhance lipid stain removal, improving the sodium sulfate to sodium carbonate ratio for improved cleaning efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional detergent compositions with lipases are used, then cleaning function is provided, but cleaning performance is reduced due to interference from other active ingredients
Solution Approach 1:
The patent extracts and removes interfering active ingredients (phosphates, aluminosilicates, enzymes, surfactants, build regulators) from the detergent composition to eliminate their negative impact on lipase activity and cleaning performance, while retaining essential components
Solution Approach 2:
The patent changes the chemical composition parameters by eliminating specific interfering substances and optimizing the ratios of remaining components, particularly maintaining sodium sulfate to sodium carbonate ratio between 1:4 and 4:1, to create a formulation that maximizes lipase effectiveness
2Reliability
If sodium sulfate to sodium carbonate ratio is increased to improve cleaning efficacy, then fat removal performance is enhanced, but formulation complexity increases
Solution Approach 1:
The patent optimizes the sodium sulfate to sodium carbonate ratio parameter within the range of 1:4 to 4:1 to achieve improved fat removal performance while maintaining formulation simplicity and avoiding excessive complexity in the detergent composition
