Post-foaming Mascia Emulsion for Volumizing Eyelashes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foaming mascara compositions either lose aeration during storage or require environmentally unfriendly volatile blowing agents, and often require separate storage of reactants before use, failing to provide a thickening appearance effectively.
Innovation Solution
A post-foaming emulsion comprising a weak acid, weak base, fatty acid, and volatile buffering agent, which forms a foam upon exposure to atmospheric conditions, allowing all ingredients to be stored in a single container and applied to eyelashes to create a volumizing effect without losing aeration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If foaming composition is stored in sealed container prior to use, then aeration is maintained, but foam loses aeration during storage and prior to use
Solution Approach 1:
The patent applies preliminary action by pre-mixing all foaming components (acid, base, surfactant) in a single container in a stable, non-foaming state. The foaming action is triggered only at the moment of application through contact with water or humidity, ensuring aeration is maintained during storage while providing reliable foam performance when needed.
2Ease of manufacture
If volatile blowing agents are used to achieve foaming, then foaming is achieved after extraction, but environmentally unfriendly solvents are required
Solution Approach 1:
The patent applies parameter changes by transitioning from volatile chemical blowing agents to a water-based foaming mechanism. The composition uses acid-base reactions with water to generate carbon dioxide gas in situ, changing the foaming mechanism from chemical volatility to controlled chemical reaction, thereby eliminating environmental harm while maintaining ease of manufacture.
3Stability of the object's composition
If reactants are stored in separate chambers, then aeration is maintained, but device complexity increases
Solution Approach 1:
The patent applies merging by combining all foaming components (acid, base, surfactant, and water) into a single homogeneous composition stored in one container. The components remain chemically stable together until triggered by water contact during application, simplifying the storage system while maintaining aeration stability.
4Quantity of substance
If multiple applications of mascara are used to achieve lash thickness, then thickening appearance is achieved, but lash clumping occurs
Solution Approach 1:
The patent applies pneumatics by using gas generation from acid-base reactions to create foam. This foam structure provides airy, separated coverage that delivers thickening appearance without the clumping associated with multiple applications of traditional mascara, as the gas bubbles create physical separation between coating layers.
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 solution allows for a single-container storage of all ingredients, maintaining the composition's aeration and providing a thickening appearance to eyelashes with a single application, addressing the issues of clumping and environmental concerns of previous technologies.
Implementation Method 1
said reaction commencing after the evaporation of said volatile buffering agent, upon exposure of said cosmetic composition to atmospheric conditions
Implementation Method 2
said cosmetic composition forms a foam, said foam resulting from the release of a gas, said gas being a reaction product of said post-foaming emulsion
