Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair care products, particularly shampoos and conditioners, cause damage to hair and scalp due to anionic surfactants, lack effective conditioning, and contribute to water and plastic waste, while existing UV protection formulations are inefficient and unsustainable.
Innovation Solution
Development of a solid, silicone-free, natural hair color and UV protection composition using p-methoxy cinnamidopropyl behenyl dimethyl ammonium chloride, blended with structuring agents, natural oils, and conditioners, which can be heated and molded into bars or powders for easy application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If liquid conditioner formulations are used to provide ease of use, then application convenience is improved, but water consumption and plastic waste increase
Solution Approach 1:
The patent changes the physical state parameter from liquid to solid bar format, eliminating the need for water as a solvent and plastic bottles for packaging. The solid bar is designed to dissolve or disperse in water during use, providing conditioning benefits while minimizing water and plastic consumption.
Solution Approach 2:
The invention utilizes phase transition by formulating the conditioner as a solid bar that transitions to liquid or dissolved state during application. This phase change allows the product to be packaged without plastic bottles and applied with minimal water, resolving the contradiction between ease of use and resource waste.
2Productivity
If anionic surfactants are used for effective hair cleansing, then cleaning efficiency is improved, but hair and scalp damage increases
Solution Approach 1:
The patent employs composite surfactant systems combining anionic, cationic, and nonionic surfactants in specific ratios. This composite approach maintains effective cleaning performance while the cationic and nonionic components mitigate the damaging effects of anionic surfactants, providing a balanced formulation that achieves both cleaning efficiency and hair health.
Solution Approach 2:
The invention introduces cationic and nonionic surfactants as intermediary components that mediate between the cleaning function of anionic surfactants and the protective needs of hair. These intermediaries reduce the harshness of anionic surfactants while preserving their cleaning effectiveness.
3Reliability
If cationic conditioning agents are added to shampoo, then conditioning effect is improved, but formulation complexity increases due to coacervate formation
Solution Approach 1:
The patent optimizes the pH parameter of the formulation to control the interaction between cationic and anionic components. By maintaining specific pH ranges, the invention prevents unwanted coacervate formation while preserving conditioning benefits, thus simplifying the formulation approach.
Solution Approach 2:
The invention applies conditioning agents with localized functionality, using specific cationic surfactants that condition hair without forming complex coacervates with anionic components. This selective approach to conditioning agent selection simplifies the overall formulation while maintaining effective conditioning.
4Object-affected harmful factors
If water-soluble UV absorbers are used for hair color protection, then UV protection is provided, but deposition on hair is insufficient
Solution Approach 1:
The patent combines water-soluble UV absorbers with cationic surfactants to create a composite system. The cationic surfactant component enhances deposition on the negatively charged hair surface, ensuring adequate UV protection agent retention while maintaining water solubility for ease of application.
Solution Approach 2:
The invention uses cationic surfactants as intermediaries that facilitate the deposition of water-soluble UV absorbers on hair. These intermediaries bridge the gap between water solubility and surface adhesion, ensuring both UV protection and sufficient deposition.
