Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cosmetic compositions for washing keratin materials often require high amounts of surfactants to achieve good foaming and detergent power, leading to increased costs and potential tolerance issues, especially with sulfate surfactants causing drying effects and sensitivity concerns.
Innovation Solution
A cosmetic composition combining linear α-olefin sulfonates with anionic surfactants and additional amphoteric or nonionic surfactants, optimizing the weight ratio to achieve superior foaming performance with reduced surfactant amounts, while maintaining skin and hair conditioning and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If sulfate surfactants are used to achieve good foaming and detergent power, then washing performance is improved, but skin and hair conditioning deteriorates due to drying effects and sensitivity issues
Solution Approach 1:
The patent changes the chemical parameters by replacing sulfate surfactants with linear alpha-olefin sulfonates and other alternative surfactants, fundamentally altering the surfactant system to achieve both good washing performance and reduced harmful effects on skin and hair
Solution Approach 2:
The patent uses a composite surfactant system combining linear alpha-olefin sulfonates with anionic, nonionic, and amphoteric surfactants in specific ratios, creating a synergistic mixture that provides both effective cleaning and gentle conditioning properties
2Productivity
If large amounts of non-sulfate surfactants are used to achieve good foaming without sulfate surfactants, then foaming power is improved, but composition cost increases and tolerance problems may occur
Solution Approach 1:
The patent optimizes the concentration parameters of the surfactant mixture, using linear alpha-olefin sulfonates at 5-50% combined with other surfactants in specific ratios to achieve effective foaming at reduced total surfactant levels compared to conventional sulfate formulations
Solution Approach 2:
The patent creates a composite surfactant blend where linear alpha-olefin sulfonates work synergistically with anionic, nonionic, and amphoteric surfactants, allowing reduced overall surfactant content while maintaining or improving foaming performance
3Ease of operation
If detergent compositions are thickened to avoid running into eyes, then application control is improved, but stability of the composition may deteriorate
Solution Approach 1:
The patent modifies the rheological parameters by incorporating specific thickening agents and optimizing the surfactant composition to achieve desired viscosity and texture while maintaining long-term stability of the formulation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition produces abundant, creamy foam with excellent persistence, providing effective cleaning and conditioning without the need for high surfactant concentrations, ensuring better tolerance and stability, even with a thickened texture.
Implementation Method 1
cosmetic compositions for washing keratin materials often contain anionic surfactants of sulfate type, which are very good detergent surfactants
Implementation Method 2
the foam generated by massaging or rubbing with the hands or a washing mitt makes it possible, after rinsing with water, to remove the diverse types of soiling
