Enzyme Denaturation in Liquid Detergent Reblending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Enzymes in liquid detergent compositions can break down other detergent ingredients, leading to reduced cleaning or care abilities, and reblending processes are compromised by the presence of enzymes, which can negatively affect the composition's integrity.
Innovation Solution
A process involving heating a first liquid detergent composition containing enzymes to a temperature between 50° C. and 90° C. for 1 minute to 360 minutes, followed by optional cooling, to selectively denature the enzymes before reblending it into a second liquid detergent composition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If enzymes are present in the first liquid detergent composition to be reblended, then cleaning and care benefits are provided, but the enzymes break down other detergent ingredients acting as substrates, negatively affecting composition integrity
Solution Approach 1:
The patent applies preliminary action by heating the first liquid detergent composition to denature enzymes before reblending occurs. This pre-treatment step inactivates the enzymes that would otherwise break down substrate ingredients during storage and reblending, preventing composition degradation while preserving cleaning benefits.
Solution Approach 2:
The patent applies preliminary anti-action by using heat to denature enzymes before they can exert their harmful effect on substrate ingredients. This counter-action neutralizes the enzyme activity that would otherwise compromise composition stability during the reblending process.
2Stability of the object's composition
If the first liquid detergent composition is heated to denature enzymes, then composition stability is improved, but energy consumption increases
Solution Approach 1:
The patent applies parameter changes by optimizing heating parameters (temperature range of 40-90°C and time of 1-360 minutes) to achieve enzyme denaturation with minimal energy input. By adjusting these parameters, the process balances composition stability improvement against energy consumption, finding an optimal operating window that is both effective and energy-efficient.
3Ease of operation
If the first liquid detergent composition is cooled after heating, then reblending into the second composition is facilitated, but processing time increases
Solution Approach 1:
The patent applies partial action by implementing optional cooling only when necessary for reblending compatibility. The cooling step is not always required - it is applied selectively based on the temperature requirements of the second liquid detergent composition, thereby reducing unnecessary processing time while still facilitating reblending when needed.
