Laundry Enzyme Composition for Sticky Soil Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current laundry detergents face challenges in effectively removing sticky microbial soils from textiles, which tend to adhere to surfaces and build up over time, leading to incomplete cleaning, particularly in areas like collars and cuffs.
Innovation Solution
A laundry cleaning composition comprising an amylase enzyme and a glycoside hydrolase enzyme from family GH 39, with the glycoside hydrolase having at least 70% identity to SEQ ID NO:1, is used to enhance soil and stain removal and reduce malodors by breaking down glycosyl bonds and releasing smaller sugars, thereby improving cleaning efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional detergents are used, then general cleaning is achieved, but sticky microbial soils and stains build up over time leading to incomplete cleaning
Solution Approach 1:
The patent introduces specific enzyme parameters (glycoside hydrolase from GH family 5, 12, 44, or 74) to change the chemical action mechanism of the detergent. These enzymes specifically target and break down glycosyl bonds in microbial soils and adhesives, transforming the cleaning mechanism from general surfactant action to specific enzymatic hydrolysis, thereby preventing soil buildup while maintaining cleaning efficacy
Solution Approach 2:
The patent creates a composite cleaning system by combining conventional detergent ingredients with specific glycoside hydrolase enzymes. This composite formulation integrates the general cleaning properties of surfactants with the specific soil-breaking capability of enzymes, achieving both immediate cleaning and prevention of microbial soil adhesion and buildup
2Reliability
If glycoside hydrolase enzymes are added to improve soil removal, then cleaning performance is enhanced, but formulation complexity increases
Solution Approach 1:
The patent selects glycoside hydrolase enzymes that perform multiple functions: they break down adhesives holding soils to fabrics, degrade polysaccharide components of microbial soils, and work across different pH and temperature conditions. This multi-functionality reduces the need for multiple specialized additives, simplifying the overall formulation while maintaining enhanced soil removal effectiveness
Solution Approach 2:
The patent optimizes enzyme parameters including selecting from four specific GH families (5, 12, 44, 74), setting concentration ranges (0.01-1000 ppm in wash liquor), and defining identity thresholds (70-100% to SEQ ID NO:1). These parameter specifications provide clear formulation guidelines that reduce complexity by eliminating trial-and-error development
