Surfactant–Polymer Cleaning Composition for Grease and Sebum

Solution Overview

Problem

Existing cleaning compositions exhibit poor grease and sebum cleaning performance.

Innovation Solution

A cleaning composition comprising a specific surfactant system and polymer, including linear alkyl benzene sulphonate surfactant, alkyl ethoxylated sulphate surfactant, and alkoxylated polymer with a core structure modified by ethylene oxide, propylene oxide, or butylene oxide, enhances grease and sebum cleaning efficacy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional cleaning compositions are used, then formulation simplicity is maintained, but grease cleaning performance is poor

Engineering Contradiction:

Improvegrease cleaning performanceVSAvoidformulation complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies composite materials by combining a specific surfactant system (anionic and nonionic surfactants) with a polymeric compound to create a synergistic cleaning composition. This composite formulation achieves superior grease cleaning performance that neither component could achieve alone, directly resolving the contradiction between performance improvement and formulation complexity.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The patent utilizes parameter changes by carefully controlling the alkoxylate ratio (EO/PO/BO) in the polymeric compound and the proportions of different surfactants. By optimizing these chemical parameters, the composition achieves enhanced grease cleaning performance while maintaining a manageable formulation structure through systematic parameter control.
