Hard Surface Cleaning Composition for Oily Soil and Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a hard surface cleaning composition that provides good environmental profile, effective emulsification, and oily soil removal without compromising consumer satisfaction in terms of cleaning performance and product appeal, while addressing consumer preferences for eco-friendly products and maintaining temperature stability.
Innovation Solution
A liquid aqueous detergent composition comprising a specific combination of anionic surfactants, amphoteric surfactants, cleaning polymers, and enzymes, with a surfactant system that includes a weight ratio of primary surfactant to secondary surfactant of 4:1 to 8:1, and a ratio of average EO of surfactant A and B combined to total surfactant B of less than 0.45, along with optional alkylbenzene sulphonates, to achieve temperature stability and cleaning efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cleaning polymer and betaine are used in liquid detergent formulations, then emulsification and oily soil removal properties are improved, but temperature stability deteriorates
Solution Approach 1:
The patent applies parameter changes by precisely controlling the weight ratio of surfactant A to surfactant B (≤1.5) and the ratio of average EO of surfactants to total surfactant B (≤0.45). These specific parameter ranges optimize both the emulsification properties and temperature stability, resolving the contradiction between improved cleaning performance and maintained stability.
Solution Approach 2:
The patent uses a composite surfactant system combining two different anionic surfactants (surfactant A with ethylene oxide units and surfactant B without) in specific ratios. This composite approach allows the system to provide both enhanced emulsification/oily soil removal and temperature stability that neither surfactant could achieve alone.
2Object-affected harmful factors
If total amount of surfactant is lowered to improve environmental profile, then eco-friendliness is improved, but cleaning efficacy deteriorates
Solution Approach 1:
The patent optimizes the surfactant composition parameters by limiting surfactant A to 1-15 ethylene oxide units and controlling the weight ratios, enabling reduced total surfactant amounts while maintaining cleaning efficacy through the specific synergistic combination of surfactants.
