Lysophospholipase Detergent Composition for Low-Temperature Sebum Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current laundry enzymes are ineffective in degrading the components of sebum, making it difficult to remove sebum stains from fabrics, especially at lower washing temperatures, and they also lack storage stability in detergent formulations.
Innovation Solution
A detergent composition containing a lysophospholipase enzyme with a sequence identity of at least 70% to SEQ. ID. 1 to 4, combined with detersive surfactants, soil release polymers, and additional enzymes, enhances sebum removal by breaking down sebum components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If current laundry enzymes are used, then the detergent formulation is simple, but sebum removal efficacy is insufficient
Solution Approach 1:
The patent combines multiple enzymes (lysophospholipase, lipase, and optionally protease, amylase, cellulase) into a single detergent formulation to achieve comprehensive sebum degradation. This merging of enzymatic functions allows simultaneous attack on different sebum components (phospholipids, triglycerides, proteins, starches, cellulose) thereby resolving the contradiction between simple formulation and effective sebum removal.
Solution Approach 2:
The detergent composition is designed with multi-functional enzyme activity to handle diverse sebum components. The lysophospholipase specifically targets phospholipids while lipase handles triglycerides, and additional enzymes provide broader coverage. This universal enzymatic approach enables effective sebum removal across different fabric types and stain severities without requiring multiple separate treatments.
2Use of energy by moving object
If washing temperature is reduced to encourage consumers, then energy consumption decreases, but sebum removal efficacy deteriorates
Solution Approach 1:
The patent replaces thermal energy (high temperature washing) with biochemical energy (enzymatic degradation). The lysophospholipase and lipase enzymes catalyze the breakdown of sebum components at low temperatures, substituting the mechanical/thermal action of hot water with biological catalysis. This allows effective sebum removal at energy-saving temperatures of 30-40°C while maintaining high cleaning efficacy.
Solution Approach 2:
The invention changes the operational parameters of the cleaning system by introducing enzymes with optimal activity at low temperatures. The lysophospholipase and lipase are engineered or selected to function optimally between 30-50°C, allowing the detergent to maintain high efficacy at reduced washing temperatures. This parameter shift from thermal to enzymatic action resolves the energy- efficacy contradiction.
3Reliability
If conventional lipase enzymes are used, then the detergent formulation is simple, but storage stability in detergent formulations is poor
Solution Approach 1:
The patent introduces a stabilizing agent or modified enzyme formulation that acts as an intermediary between the enzyme and the detergent matrix. This intermediary component protects the lysophospholipase and lipase from denaturation and inactivation during storage, improving stability without requiring complex formulation adjustments. The stabilizing agent mediates between enzyme sensitivity and detergent compatibility.
Solution Approach 2:
The invention modifies the enzyme parameters through protein engineering or selective breeding to enhance storage stability. The lysophospholipase and lipase are engineered with improved structural stability, extended half-life, and enhanced resistance to proteolytic degradation and temperature fluctuations. These parameter changes in enzyme structure and function allow long-term storage stability while maintaining catalytic activity.
4Productivity
If current enzymes are used, then manufacturing cost is low, but cleaning performance on sebum stains is insufficient
Solution Approach 1:
The patent segments the sebum degradation function into multiple specialized enzymatic activities. Instead of relying on a single non-specific lipase, the formulation divides the cleaning task among lysophospholipase for phospholipid breakdown, lipase for triglyceride hydrolysis, and optional auxiliary enzymes. This segmentation of functional responsibilities enhances overall cleaning performance on complex sebum stains while maintaining manageable manufacturing through modular enzyme addition.
