Detergent Tablet Composition for Enzyme Stability and Softener Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solid detergent tablets have issues with enzyme deactivation due to high temperatures during drying, poor stability due to moisture and environmental factors, and require separate addition of softeners, leading to precipitation and reduced cleaning effectiveness.
Innovation Solution
Incorporating enzyme preparations and softener components as solid particles within detergent tablets, using a formulation of 8-34 parts water-soluble polymer, 14-50 parts surfactant, 0.1-50 parts enzyme preparation, 0.1-50 parts softener preparation, and 1-10 parts foaming agent, with specific polymer types and particle sizes to maintain stability and prevent precipitation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If high temperature drying is used to evaporate water and achieve high concentration and portability, then the detergent tablet achieves high concentration and portability, but the enzyme preparation is deactivated due to high temperature
Solution Approach 1:
The detergent tablet is divided into multiple functional layers: an outer water-soluble polymer coating layer and an inner core containing enzyme preparation and other detergent ingredients. This segmentation allows the enzyme preparation to be protected from high temperature drying while still achieving high concentration and portability of the detergent formulation.
Solution Approach 2:
A water-soluble polymer coating is introduced as an intermediary layer between the enzyme preparation and the external environment. This coating protects the enzyme preparation from deactivation during high temperature drying while allowing the detergent to maintain its high concentration and portable form.
2Reliability
If liquid enzyme preparation is added by spraying and smearing to increase cleaning power, then the detergent tablet has enhanced cleaning function, but the detergent tablet dissolves and becomes sticky and soft due to excessive water and organic solvent
Solution Approach 1:
The physical state of the enzyme preparation is changed from liquid to solid particles. This parameter change allows the enzyme preparation to be incorporated into the detergent tablet without adding excessive water or organic solvents, maintaining both cleaning power and storage stability while avoiding dissolution and stickiness.
Solution Approach 2:
The detergent tablet is formulated as a composite material combining water-soluble polymer, surfactant, solid enzyme preparation particles, and softener preparation. This composite structure provides enhanced cleaning power while maintaining storage stability, as the solid particles are integrated into the matrix rather than added as liquid.
3Ease of operation
If cationic softener component is directly added to the detergent to eliminate static electricity, then the softening function is achieved, but precipitation occurs due to mutual absorption of heterogeneous charges between cationic softener and anionic surfactant
Solution Approach 1:
The softener preparation is segmented into solid particles that are physically separated from the anionic surfactant in the detergent matrix. This segmentation prevents direct contact between cationic softener and anionic surfactant, avoiding precipitation while maintaining both softening and detergency functions.
Solution Approach 2:
The water-soluble polymer matrix acts as an intermediary that physically separates the cationic softener particles from the anionic surfactant. This intermediary structure prevents mutual absorption of heterogeneous charges while allowing both components to function independently - the surfactant for detergency and the softener for static elimination.
