Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair dye products using liquid oxidizing agents face challenges with packaging due to reactivity, leading to inefficiencies and environmental concerns, and struggle to maintain viscosity with solid oxidizing agents, affecting handling and storage.
Innovation Solution
A cosmetic product using a solid oxidizing agent, such as percarbonate, perborate, or percarbamide salt, combined with a mixture of ionic and non-ionic polysaccharides as thickening agents, allowing for stable storage and improved viscosity management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If liquid oxidizing agents are used in hair dye products, then the oxidizing function is effective, but packaging becomes complex and bulky due to reactivity concerns
Solution Approach 1:
The patent changes the physical state of the oxidizing agent from liquid to solid form. Solid oxidizing agents are less reactive and more stable, allowing for simplified packaging without compromising the oxidizing function. This parameter change resolves the contradiction between maintaining reliability and reducing packaging volume.
Solution Approach 2:
The patent extracts the water component from the oxidizing agent formulation, transforming it from a liquid solution to a solid powder form. This extraction of the liquid medium eliminates the reactivity issues associated with liquid peroxide while preserving the oxidizing capability, thereby reducing packaging requirements.
2Volume of stationary object
If solid oxidizing agents are used to reduce packaging bulk, then packaging volume is reduced, but viscosity control becomes difficult affecting handling
Solution Approach 1:
The patent introduces thickening agents as intermediaries to control the viscosity of the final hair dye composition. These thickening agents modify the rheological properties of the mixture, ensuring proper handling and application characteristics even when using solid oxidizing agents, thus resolving the contradiction between reduced packaging volume and ease of operation.
3Stability of the object's composition
If solid oxidizing agents are used, then storage stability is improved, but viscosity management becomes challenging
Solution Approach 1:
The patent employs composite material strategies by combining solid oxidizing agents with specific thickening agents and other formulation components. This composite approach allows simultaneous achievement of storage stability through the solid oxidizing agent and proper viscosity management through the thickening agents, resolving the contradiction between stability and complexity.
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 product achieves stable storage, reduced packaging bulk, and enhanced handling properties by using a solid oxidizing agent with a polysaccharide mixture, ensuring effective and long-lasting hair dye application.
Implementation Method 1
Oxidative colouring agents on the commercial market usually have the form of bi-component media in which two different preparations are present... The first preparation is a formulation... which contains for example liquid hydrogen peroxide in concentrations from about 1.5 to about 12 wt % as the oxidising agent
Implementation Method 2
oxidising dye precursors, called developer components and coupler components, which under the effect of oxidising agents—most often hydrogen peroxide—combine to form the actual colouring agents
Implementation Method 3
The composition that contains an oxidising agent includes a thickening agent... the two or more thickening agents comprise an at least partially ionic polysaccharide and a substantially non-ionic polysaccharide
