Detergent Tablet Production via Optimized Premix Composition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing processes for producing detergent or cleaning agent tablets face challenges in achieving a balance between sufficient hardness for handling and transportation without requiring storage, while also ensuring rapid disintegration in aqueous solutions, often necessitating high compression forces and additional additives.
Innovation Solution
A multi-stage process involving a specific powdered premix composition comprising sodium carbonate, sodium percarbonate, methylglycinediacetic acid, non-ionic surfactant, and washing-active polymer, compressed at moderate forces to create tablets with enhanced hardness and disintegration properties, eliminating the need for storage and reducing adhesion to equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If high compression force is applied to increase tablet hardness, then tablet strength is improved, but disintegration time increases (slower disintegration)
Solution Approach 1:
The patent changes the chemical composition parameters of the premix by incorporating specific builders (sodium carbonate, sodium percarbonate, MGDA) and polymers in optimized ratios. This chemical parameter change allows the tablet to achieve sufficient hardness at lower compression forces while maintaining rapid disintegration, resolving the contradiction between strength and disintegration time
Solution Approach 2:
The patent uses a composite premix formulation combining multiple functional ingredients: builders (sodium carbonate, sodium percarbonate, MGDA), non-ionic surfactant, and washing-active polymer. This composite material approach creates synergistic effects that enable both adequate tablet hardness and rapid disintegration without requiring high compression forces
2Ease of manufacture
If high compression force is used to produce hard tablets, then manufacturing simplicity is maintained, but energy consumption increases
Solution Approach 1:
The patent optimizes the premix composition parameters to enable compression at lower forces (10-30 kN instead of higher forces). This parameter change reduces energy consumption during tabletting while maintaining manufacturing simplicity through the use of conventional tablet press equipment
3Productivity
If conventional premix formulations are used, then production process is simple, but adhesion to equipment occurs requiring maintenance
Solution Approach 1:
The patent modifies the chemical composition parameters of the premix by incorporating specific builders and polymers that alter the surface properties and flow characteristics. This reduces adhesion to equipment surfaces, minimizing production rejects and maintenance requirements while maintaining efficient production
4Duration of action of moving object
If additional additives like polyethylene glycols and disintegrants are used, then tablet disintegration is improved, but device complexity increases
Solution Approach 1:
The patent makes the premix composition itself multi-functional: the combination of builders (sodium carbonate, sodium percarbonate, MGDA), non-ionic surfactant, and washing-active polymer serves both as the cleaning active ingredients and as the disintegration mechanism. This eliminates the need for separate disintegrant additives, reducing formulation complexity while ensuring rapid disintegration
Solution Approach 2:
The patent extracts the disintegration function from separate additive components and integrates it into the core premix formulation. The builder-polymer-surfactant system itself provides the disintegration mechanism through its chemical properties, eliminating the need for additional disintegrant additives
