Non-Hydroxide Alkaline Composition for Multi-Soil Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detergents and cleaning compositions often require costly specialty additives for specific cleaning tasks, and there is a need for a multipurpose alkaline composition that can effectively remove challenging soils without these additives.
Innovation Solution
A multipurpose alkaline composition comprising a non-hydroxide alkalinity source, surfactant, chelant, and solvent system, with a pH less than 11.5, which can be used as a pre-spray or pre-treatment for enhanced cleaning and sanitizing without the need for PPE, effectively removing soils like tea stains, coffee stains, and hard water deposits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If specialty additives are included in detergent formulations to accomplish specific cleaning outcomes, then cleaning performance for specific soils is improved, but formulation cost increases
Solution Approach 1:
The patent creates a universal alkaline cleaning composition that can effectively remove multiple types of soils (polymerized soils, stains, hard water deposits, fats, oils, cosmetics) using a single base formulation with non-hydroxide alkalinity source, surfactant, chelant, and solvent system. This multi-functional approach eliminates the need for separate specialty detergent formulations for different cleaning tasks, thereby reducing formulation costs while maintaining effective cleaning performance across diverse applications.
2Reliability
If hydroxide-based highly alkaline compositions are used to remove challenging soils, then cleaning efficacy is improved, but corrosiveness and safety hazards increase
Solution Approach 1:
The patent changes the chemical parameter of alkalinity from hydroxide-based (highly alkaline, corrosive) to non-hydroxide alkalinity sources with controlled pH less than 11.5. This parameter change maintains the necessary cleaning efficacy for removing challenging soils while significantly reducing corrosiveness and safety hazards. The non-hydroxide alkalinity source provides sufficient alkaline cleaning action without the extreme pH levels that cause corrosion and require PPE.
3Reliability
If specialty cleaning compositions are formulated for specific applications, then cleaning effectiveness is improved, but adaptability to different markets and applications decreases
Solution Approach 1:
The patent develops a single multipurpose alkaline composition that effectively handles diverse cleaning challenges including polymerized soils, tea stains, coffee stains, hard water scale, polymerized oils, carbonized soils, baked-on soils, fats, oils, and cosmetics. This universal formulation can be applied across different markets and cleaning scenarios (pre-spray, spot treatment, pre-treatment for machine and manual warewash), providing both cleaning effectiveness and broad market adaptability without requiring multiple specialized formulations.
