Detergent Tablet Composition for Fast Dissolution and Low Residue
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Detergent tablets dissolve too slowly in tap water, leading to prolonged waiting times before use and potential residues on substrates, especially in high-volume usage environments like industrial cleaning.
Innovation Solution
A detergent tablet formulation comprising glucose monohydrate and polyvinyl polypyrrolidone (PVPP) at specific weight ratios, providing structural integrity while ensuring rapid dissolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional detergent tablet formulations are used, then structural integrity is maintained, but dissolution time is too long
Solution Approach 1:
The patent changes the chemical composition parameters by incorporating glucose monohydrate (30-70 wt%) and PVPP (4-20 wt%) in specific ratios, along with surfactants and optional effervescent agents. This parameter optimization enables the tablet to dissolve rapidly (5 minutes or less) while preserving structural integrity for handling and storage.
Solution Approach 2:
The invention uses a composite material system combining glucose monohydrate (soluble disintegrant), PVPP (insoluble disintegrant providing structural framework), surfactants, and optional effervescent agents. This composite structure allows the tablet to maintain strength during storage while achieving rapid dissolution when water is added.
2Productivity
If conventional detergent tablets are used, then ease of storage is maintained, but user waiting time increases
Solution Approach 1:
By optimizing the composition parameters—specifically glucose monohydrate (30-70 wt%), PVPP (4-20 wt%), and surfactant content—the tablet achieves rapid dissolution (5 minutes or less) without compromising storage stability. This parameter tuning directly improves cleaning efficiency by eliminating prolonged waiting times while maintaining ease of storage.
3Reliability
If tablet dissolution is incomplete, then storage stability is maintained, but residue formation on substrates occurs
Solution Approach 1:
The patent optimizes composition parameters to ensure complete dissolution: glucose monohydrate (30-70 wt%) provides soluble disintegration, PVPP (4-20 wt%) provides structural framework, and surfactants ensure complete wetting and dissolution of all components. This prevents residue formation on substrates while maintaining storage stability.
Solution Approach 2:
The patent introduces effervescent agents (sodium bicarbonate 1-20 wt%, citric acid 1-20 wt%) as intermediaries that generate CO2 bubbles upon contact with water. This effervescent action mechanically disrupts the tablet structure, accelerating disintegration and ensuring complete dissolution of all ingredients, thereby preventing residue formation while maintaining storage stability.
