Hair Styling Foam Composition Using Alkane and Dimethylether Propellants
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair styling compositions fail to effectively increase hair volume while maintaining natural appearance and shine, and do not allow for easy restyling without negatively affecting hair feel or shine.
Innovation Solution
A hair styling foam composition based on an aqueous or aqueous-alcoholic medium containing at least one cationic polymer, one silicone oil, one thickening polymer, and a propellant mixture of alkane and dimethylether, with specific ratios and concentrations to enhance hair volume and styling benefits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If synthetic polymers are used for hair styling, then hair hold and styling performance are improved, but natural hair feel and shine are compromised
Solution Approach 1:
The patent combines multiple polymers (polyquaternium-68, polyvinylpyrrolidone, and carboxymethyl cellulose) with silicones and propellants to create a composite aerosol composition that delivers both strong hold and natural feel, resolving the contradiction between styling performance and natural appearance
Solution Approach 2:
The patent specifies precise concentration ranges for each ingredient (e.g., polyquaternium-68 at 0.1-15%, polyvinylpyrrolidone at 1-20%, carboxymethyl cellulose at 0.01-5%) to optimize the balance between hold strength and natural appearance, demonstrating parameter optimization to resolve the contradiction
2Volume of moving object
If hair styling composition is applied to increase volume, then hair volume is improved, but natural appearance may be compromised
Solution Approach 1:
The foam formulation provides localized volume enhancement at the roots while maintaining natural appearance throughout the hair, with the aerosol delivery system enabling precise application to specific areas needing volume without over-styling other areas
3Reliability
If strong holding polymers are used, then styling hold is improved, but restyling capability and natural feel deteriorate
Solution Approach 1:
The patent creates a dynamic styling system where the foam initially provides strong hold through polymer film formation, but the aerosol propellant system allows for easy restyling by re-aerosolizing and redistributing the polymers, enabling the composition to transition between hold and restyling states
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 provides excellent hair volume, natural feel, and shine, allowing for easy restyling without compromising hair appearance or shine, and is characterized by a distinct 'cracking sound' when the foam disappears.

AI summary
Present invention relates to a hair styling gel foam which boosts exceptionally hair volume. The inventors have surprisingly found out that a composition comprising at least one cationic polymer, at least one silicone oil, at least one thickener and a propellant mixture of alkane and dimethylether in an aqueous or aqueous- alcoholic medium has excellent hair styling and restyling benefits together with excellent volumizing and bodifying effects and also exceptional with the cracking sound heard when foam disappears. The hair feels excellently natural both visually and upon touching and looks excellently shiny.
