Sugar Amine Liquid Detergent Composition for Mildness and Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid laundry detergent compositions often cause skin and eye irritation due to surfactant compositions, and there is a need for improved mild formulations that maintain good cleaning performance.
Innovation Solution
A liquid detergent composition comprising a sugar amine, a fatty alcohol ethoxylate, an anionic surfactant, and water, with specific weight percentages and optional additives such as tetraborate salts, strong bases, weak acids, and enzymes, which acts as a pH buffer and chlorine scavenger.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional surfactant compositions are used in liquid detergent, then good cleaning performance is achieved, but skin and eye irritation occurs
Solution Approach 1:
The patent changes the chemical parameters of the detergent formulation by incorporating sugar amines (such as glucosamine, galactosamine, N-acetylglucosamine, N-acetylgalactosamine) and their salts. These sugar amine components modify the surfactant system's properties to reduce irritation while preserving cleaning efficacy. The specific parameter changes include using sugar amine derivatives with specific molecular structures that are gentler on skin and eyes compared to conventional surfactants.
Solution Approach 2:
The patent creates a composite detergent composition that combines multiple surfactant types including anionic surfactants, nonionic surfactants, and sugar amine-based surfactants. This composite approach allows the formulation to leverage the cleaning power of anionic surfactants while the sugar amine components provide mildness and reduce irritation. The synergistic combination achieves both high cleaning performance and skin friendliness.
2Object-affected harmful factors
If mild liquid detergent formulations are developed, then skin and eye irritation is reduced, but cleaning performance may be compromised
Solution Approach 1:
The patent merges multiple surfactant classes into a single formulation: anionic surfactants for cleaning power, nonionic surfactants for mildness and foam stability, and sugar amine-based surfactants that provide both cleaning and skin-protective properties. This merging allows the formulation to achieve mildness without sacrificing cleaning performance, as the different surfactant types work synergistically.
Solution Approach 2:
The sugar amine components serve multiple functions simultaneously: they act as surfactants for cleaning, as pH buffers to maintain formulation stability, and as skin-protective agents to reduce irritation. This multi-functionality allows a single ingredient to contribute to both mildness and cleaning performance, resolving the contradiction between the two requirements.
