Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slimming cosmetic products with high inorganic salt concentrations face stability issues and provide either low spreadability and heaviness or short residence time on the skin, failing to combine effectiveness with pleasantness and stability.
Innovation Solution
A gel cosmetic composition with a viscosity range of 50,000 to 200,000 mPa*s, containing 8-15% inorganic salt, 0.5-3% caffeine, 5-20% ethanol, and an association of xanthan gum with a cellulose derivative, excluding emulsifying agents and fat components, which ensures stability, spreadability, and prolonged skin residence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the concentration of inorganic salts is increased to achieve effective slimming action, then the slimming effectiveness is improved, but the formulation stability deteriorates
Solution Approach 1:
The patent introduces a specific association of xanthan gum with cellulose derivative as a mediating stabilizing system that enables high inorganic salt concentration (8-15%) to be maintained without compromising formulation stability. This gel-forming association acts as an intermediary structure that prevents salt crystallization and maintains homogeneous distribution.
Solution Approach 2:
The patent changes the physical state parameter by formulating a gel composition with specific viscosity (50,000-200,000 mPa*s) that can accommodate high salt concentrations. The gel matrix transforms the formulation from a liquid or emulsion state to a structured gel state, fundamentally changing how the inorganic salts are held and stabilized within the composition.
2Stability of the object's composition
If the product is formulated as an emulsion with fat components to improve stability, then the formulation stability is improved, but the spreadability and skin lightness deteriorate
Solution Approach 1:
The patent extracts and eliminates emulsifiers and fat components from the formulation, replacing the traditional emulsion stability mechanism with a gel-based stabilization system using xanthan gum and cellulose derivative association. This removal of heavy emulsive components directly improves spreadability and skin lightness while maintaining stability through the gel network.
Solution Approach 2:
The patent changes the formulation from an emulsion system (liquid/semi-liquid with fat phases) to a gel system (structured network with high viscosity), fundamentally altering the physical parameters. The gel structure provides stability without requiring emulsifiers, and the high viscosity (50,000-200,000 mPa*s) ensures proper residence time on skin.
3Ease of operation
If the product is formulated as a liquid to improve spreadability and skin lightness, then the ease of operation is improved, but the residence time on skin deteriorates
Solution Approach 1:
The patent changes the viscosity parameter to a specific high range (50,000-200,000 mPa*s) that transforms the product from a free-flowing liquid to a structured gel. This viscosity modification allows the product to spread easily during application (due to shear-thinning properties typical of xanthan gum gels) but then maintains its position on the skin without running or dripping, thereby extending residence time.
Solution Approach 2:
The patent creates a composite gel material combining xanthan gum and cellulose derivative in specific ratios, forming a network structure that provides both spreadability and residence time. This composite gel system exhibits non-Newtonian flow characteristics that enable easy application followed by stable adhesion to the skin surface.
4Stability of the object's composition
If emulsifiers and fat components are included to improve stability, then the formulation stability is improved, but the skin permeability and freshness deteriorate
Solution Approach 1:
The patent extracts and removes emulsifiers and fat components from the formulation, eliminating the barrier these substances create to skin permeability. The resulting gel formulation, based on xanthan gum and cellulose derivative association, allows for better skin penetration of active ingredients including caffeine and inorganic salts, while maintaining stability through the gel network structure.
