Solution Overview
Problem
Existing skin and hair care compositions face challenges in maintaining stability at normal and elevated temperatures, preventing phase separation upon dilution, and providing sensory benefits like softness while allowing for the application of oil-soluble components, while ensuring skin compatibility and moisturization.
Innovation Solution
The composition includes hydrogenated and non-hydrogenated ethoxylated and propoxylated triglycerides of ricinoleic acid, ethoxylated and propoxylated glycerol fatty acid mono- and diesters, polyols, and glycerol fatty acid monoesters, with specific ethoxylation and propoxylation degrees, along with limited water content, to achieve flowability, stability, and sensory properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the composition contains high proportions of emulsifiers and additives to achieve stability and sensory properties, then the sensory properties and stability are improved, but the viscosity increases and pumpability deteriorates
Solution Approach 1:
The patent applies parameter changes by carefully controlling the degree of ethoxylation and propoxylation of the triglycerides and glycerol esters. By optimizing these chemical parameters (degree of ethoxylation ≥20, degree of propoxylation ≥20), the composition achieves both stability and low viscosity, resolving the contradiction between reliability and ease of operation.
Solution Approach 2:
The patent uses composite materials by combining multiple ethoxylated and propoxylated compounds with different molecular structures and properties. The composition includes ethoxylated triglycerides, propoxylated triglycerides, ethoxylated glycerol esters, and propoxylated glycerol esters, creating a synergistic mixture that provides both stability and flowability.
2Ease of operation
If the composition is diluted with water to reduce viscosity and improve flowability, then the pumpability is improved, but phase separation occurs and stability deteriorates
Solution Approach 1:
The patent uses ethoxylated and propoxylated compounds as intermediary substances that bridge the hydrophilic and lipophilic phases. These compounds with specific ethoxylation/propoxylation degrees act as mediators that prevent phase separation upon water dilution, maintaining stability while achieving good flowability.
Solution Approach 2:
The patent applies parameter changes by controlling the water content at ≤20% and optimizing the ethoxylation/propoxylation degrees of the components. This parameter optimization ensures the composition remains stable even when diluted with water, preventing phase separation while maintaining pumpability.
3Productivity
If the composition is stored at elevated temperatures to accelerate processing and application, then the productivity is improved, but thermal stability deteriorates and component separation occurs
Solution Approach 1:
The patent uses composite materials with ethoxylated and propoxylated triglycerides and glycerol esters that inherently resist thermal degradation. The synergistic combination of these stabilized compounds maintains composition integrity at elevated temperatures, enabling faster processing without component separation.
Solution Approach 2:
The patent applies parameter changes by selecting compounds with specific ethoxylation and propoxylation degrees that provide thermal stability. These parameter-optimized compounds maintain their structural integrity at elevated temperatures, allowing accelerated processing while preventing thermal degradation and phase separation.
4Reliability
If conventional emulsifiers are used to achieve stability, then the stability is improved, but the composition becomes viscous and difficult to pump
Solution Approach 1:
The patent fundamentally changes the chemical parameters of the emulsifying agents by using ethoxylated and propoxylated compounds with specific degrees of modification (≥20). This parameter change transforms conventional viscous emulsifiers into low-viscosity, pumpable compounds that maintain stability, directly resolving the contradiction between reliability and device complexity.
