Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solid alkaline detergent compositions face challenges in dissolving readily in aqueous media without altering the pH of the use solution, particularly when using acid/base dissolution aids that consume alkalinity sources.

Incorporating a catalase enzyme as a dissolution aid in solid cleaning compositions, which includes a peroxygen source and surfactant, to facilitate controlled dissolution without altering the pH of the use solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If acid/base dissolution aids are used to increase dissolution speed, then dissolution rate is improved, but alkalinity is consumed and pH of use solution increases
Solution Approach 1:
The patent introduces an enzyme (catalase or peroxidase) as an intermediary substance that mediates the dissolution process. The enzyme catalyzes the decomposition of peroxide to generate oxygen bubbles, which physically disrupt and accelerate the dissolution of the detergent matrix without consuming alkalinity. This intermediary mechanism resolves the contradiction by providing rapid dissolution while maintaining pH stability.
Solution Approach 2:
The patent changes the chemical mechanism from acid-base reaction to enzyme-catalyzed decomposition. By using enzymes and peroxides instead of traditional acid/base dissolution aids, the system achieves rapid dissolution through biological catalysis while avoiding pH-altering chemical reactions. This parameter change in the dissolution mechanism eliminates the harmful effect of pH alteration.
2Productivity
If traditional dissolution aids are used, then dissolution speed increases, but the composition becomes incompatible with lower pH formulations
Solution Approach 1:
The enzyme acts as a pH-neutral intermediary that facilitates dissolution without being dependent on acidic or basic conditions. Unlike traditional dissolution aids that require alkaline environments to function, enzymes such as catalase and peroxidase operate effectively across a broader pH range, enabling the formulation to work in lower pH compositions while maintaining rapid dissolution performance.
Solution Approach 2:
The enzyme-based dissolution system provides universal applicability across different pH ranges and surfactant types. The enzyme-catalyzed peroxide decomposition mechanism is not limited to alkaline conditions, making the formulation versatile for various cleaning applications including acidic, neutral, and alkaline environments, thus enhancing adaptability.
