Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solid, compact cosmetic gel products face challenges in achieving high volumes and varied shapes due to high water content, which requires sealed packaging and limited mold volume, making it difficult to produce products with complex reliefs.
Innovation Solution
A process involving the use of thermoreversible polysaccharides, humectants, emollients, and a powder phase, where an aqueous paste is heated to form a pourable mixture, poured into a mold, and then subjected to heat treatment to remove water, resulting in a solid, compact powder cosmetic product with a soft creaminess texture and high volume, allowing for complex shapes and patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If water is used as a solvent in cosmetic gel products, then the product has good texture and applicability, but it requires sealed packaging to prevent volatile component loss and limits the product volume
Solution Approach 1:
The patent removes water from the cosmetic product formulation, transitioning from a water-based gel to an anhydrous or low-water powder product. This extraction of the problematic component (water) eliminates the need for sealed packaging while preserving product functionality through alternative solvent systems and encapsulation technologies.
Solution Approach 2:
The patent changes the water content parameter from high (traditional gel) to low or zero (anhydrous powder), fundamentally altering the product's physical state and storage requirements. This parameter change enables the product to achieve both good texture and resistance to volatile component loss.
2Ease of manufacture
If traditional heating and molding process is used, then the product solidifies without clear solid-liquid transition, but it limits the product volume and complexity of shapes
Solution Approach 1:
The patent utilizes controlled phase transitions of thermoreversible gelling agents to achieve a clear solid-liquid transition during processing. This allows the product to be molded in a liquid state and then transition to a solid state with defined shapes and high volumes, overcoming the limitations of progressive solidification.
Solution Approach 2:
The patent employs composite formulations combining thermoreversible gelling agents with powders and other cosmetic ingredients. This composite approach enables the product to achieve high volumes and complex shapes while maintaining structural integrity during the phase transition from liquid to solid state.
3Ease of operation
If high water content is used in cosmetic gel, then the product has satisfactory texture, but it requires sealed container packaging and limits volume expansion
Solution Approach 1:
The patent extracts water from the formulation to create an anhydrous or low-water product, eliminating the need for sealed packaging while maintaining cosmetic functionality through alternative ingredient systems that provide similar sensory properties without the drawbacks of high water content.
