Solid Cosmetic Formulation Using Amino Acid Gelling Agent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetics in emulsified systems are prone to destabilization due to variations in materials, leading to inconsistent visual and topical performance, and are often bulky due to water content, increasing transportation costs.
Innovation Solution
A solid cosmetic formulation using an amino acid oil-gelling agent and a fatty acid ester component, with seed or vegetable oils, and minimal water and polyamides, allowing for a stable, non-emulsified, and concentrated product that maintains performance across temperature variations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional emulsified systems are used to combine aqueous and oily phases, then cosmetic active agents with different affinities can be combined, but the emulsion becomes unstable and visual/topical performance varies
Solution Approach 1:
The patent removes the aqueous phase from the cosmetic formulation, creating an anhydrous system. This extraction of water eliminates the emulsion structure entirely, preventing destabilization while maintaining the ability to combine oil-soluble and water-soluble active agents through alternative solubilization methods using the amino acid oil-gelling agent
Solution Approach 2:
The invention changes the fundamental parameter of water content from present (emulsified system) to absent (anhydrous system). This parameter change transforms the system from an unstable emulsion to a stable anhydrous formulation, fundamentally resolving the stability issue while preserving ingredient compatibility
2Adaptability or versatility
If water is added to the cosmetic composition, then cosmetic active agents with different affinities can be combined, but the composition volume increases and transportation costs rise
Solution Approach 1:
The patent extracts and eliminates water from the cosmetic formulation, creating a concentrated anhydrous product. This removal of unnecessary water volume reduces transportation costs and shipping weight while maintaining the functional ability to combine diverse cosmetic active agents through the oil-based amino acid gelling system
3Ease of manufacture
If anhydrous cosmetics are made opaque and readily water-soluble, then manufacturing is simplified, but the product lacks visual appeal and resistance to melting
Solution Approach 1:
The invention changes the optical parameter from opaque to translucent by selecting specific oil-soluble ingredients and the amino acid oil-gelling agent that allow light transmission. This parameter change achieves both visual appeal and enhanced stability, as the translucent anhydrous formulation resists melting better than conventional opaque emulsions while remaining manufacturable
