Butter and Styrenic Film Former Eyelash Composition for Easy Deposition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic compositions for eyelashes and eyebrows face challenges in maintaining conditioning benefits while preserving ease of deposition, build-up, and removal, often requiring harsh methods to remove treatments, and are prone to damage from environmental stresses.
Innovation Solution
A cosmetic composition comprising natural origin butters and styrenic film formers, with specific viscosity and modulus properties, is applied to keratin materials for conditioning, allowing easy removal and enhancing deposition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high loads of conditioning agents (such as butters or waxes) are added to condition eyelashes during wear, then conditioning benefits are improved, but ease of deposition, build-up, evenness of coating, and other performance characteristics deteriorate
Solution Approach 1:
The patent changes the physical-chemical parameters of the conditioning agents by selecting specific butters (cocoa, shea, mango, jojoba) with controlled molecular structures and ratios, and combines them with film formers to adjust viscosity and flow characteristics, enabling easy deposition while maintaining conditioning benefits
Solution Approach 2:
The patent creates a composite formulation combining multiple butters (cocoa, shea, mango, jojoba) with film forming polymers to achieve synergistic effects where the composite material provides both easy application and sustained conditioning performance that individual ingredients cannot achieve alone
2Duration of action of stationary object
If harsh removal techniques are used to remove treatments or coloring, then durability of treatment is improved, but damage to eyelashes and eyebrows increases
Solution Approach 1:
The patent converts the potential harm of difficult removal into a benefit by formulating the mascara with specific butter and film former combinations that enable gentle, easy removal while maintaining durability during wear, turning the removal process from harmful to beneficial for lash health
3Duration of action of stationary object
If environmental stresses are exposed to eyelashes daily, then natural wear is accepted, but accumulation of damage occurs
Solution Approach 1:
The patent applies conditioning agents before environmental damage occurs, using butter and film former combinations that create a protective barrier and maintain lash health during exposure to environmental stresses, preventing damage accumulation rather than addressing it after occurrence
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 effectively conditions eyelashes and eyebrows, ensuring easy application and removal, while maintaining performance characteristics, and providing increased deposition weight and surface area.
