Enzyme Cleaning Compositions for Sticky Microbial Soil Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current detergent compositions face challenges in effectively removing sticky microbial soils from surfaces like textiles, which tend to adhere to body soils and particulate soils, leading to incomplete cleaning, especially on areas like collars and cuffs.
Innovation Solution
A cleaning composition comprising an anionic surfactant system, an amylase enzyme, and a glycosyl hydrolase enzyme with specific glycoside hydrolase activity, such as endo-alpha-1,4-polygalactosminidase or glycoside hydrolase family GH 39 enzymes, is used to enhance soil and stain removal and reduce malodor, particularly for body soil.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional detergent compositions are used, then general cleaning is achieved, but sticky microbial soils and body soils cannot be effectively removed
Solution Approach 1:
The patent applies parameter changes by introducing specific enzymes (glycosyl hydrolases from GH families 39, 47, 66, 78, 114 and endo-alpha-1,4-polygalactosminidase) with optimized catalytic parameters to break down the glycosidic bonds in microbial polysaccharides. This enzymatic parameter change enables effective degradation of sticky soils that conventional detergents cannot remove, directly resolving the contradiction between general cleaning effectiveness and specific microbial soil removal.
Solution Approach 2:
The patent employs composite materials by formulating a detergent composition that combines conventional surfactants with specific glycosyl hydrolase enzymes. This composite approach integrates the general cleaning capability of surfactants with the targeted degradation capability of enzymes, enabling simultaneous removal of both general soils and sticky microbial soils, thus resolving the contradiction between general cleaning and specific soil type effectiveness.
2Productivity
If microbial soils are not effectively removed, then cleaning cycle is completed, but soil builds up over time on surfaces
Solution Approach 1:
The patent applies preliminary action by incorporating enzymes that proactively break down microbial polysaccharides during the cleaning cycle, preventing soil buildup before it occurs. The glycosyl hydrolases act on microbial soils during washing, collars, and cuffs treatments to prevent the progressive adhesion and buildup of soils over time, thus extending the duration between required cleanings while maintaining productivity.
3Ease of operation
If conventional cleaning compositions are used, then routine cleaning is achieved, but incomplete cleaning occurs on collars and cuffs
Solution Approach 1:
The patent applies local quality by concentrating glycosyl hydrolase enzymes in formulations specifically designed for treating areas prone to microbial soil buildup, such as collars and cuffs. The enzymes provide localized enzymatic activity precisely where microbial polysaccharides accumulate, ensuring complete cleaning of these challenging areas while maintaining the simplicity of routine cleaning operations through easy-to-use detergent formulations.
