Effervescent Tablet Floating Delay via Specific Gravity Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cosmetic bubbling tablets face challenges in maintaining size limitations, achieving long-term use, and delivering a carbonic acid bubbling effect due to volatility and precipitation issues, which hinder the delivery of skin cosmetic effects.
Innovation Solution
A cosmetic kit comprising a bubbling tablet with a specific ratio of sodium bicarbonate, alpha-hydroxyl acid, crystalline alpha-hydroxyl acid, and a water-soluble lubricant, combined with skin water containing an aliphatic compound, emollient, surfactant, and carbonated water, optimized for delayed floating and enhanced carbonic acid concentration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If a bubbling tablet is designed to float in skin water, then the tablet can be used for a long time, but the tablet size is limited by the container ejection portion
Solution Approach 1:
The patent modifies the specific gravity of the tablet by adjusting the ratio of sodium bicarbonate to alpha-hydroxyl acid and adding crystalline alpha-hydroxyl acid, enabling the tablet to delay floating while maintaining a small size suitable for container ejection
2Ease of manufacture
If carbonic acid is used for bubbling, then the bubbling effect is achieved, but carbonic acid evaporates to air rather than dissolving in skin water
Solution Approach 1:
The patent changes the chemical parameters by using sodium bicarbonate and alpha-hydroxyl acid instead of direct carbonic acid, generating carbon dioxide bubbles in situ that dissolve in skin water to form carbonic acid, preventing evaporation loss
Solution Approach 2:
The patent utilizes the phase transition from solid sodium bicarbonate and crystalline alpha-hydroxyl acid to gaseous carbon dioxide, which then dissolves in liquid skin water to form carbonic acid, maintaining the bubbling effect while preventing evaporation
3Stability of the object's composition
If the tablet dissolves completely in skin water, then no precipitation occurs, but the bubbling capability may be reduced
Solution Approach 1:
The patent optimizes the specific gravity and surface tension parameters of the tablet by controlling the ratio of sodium bicarbonate to alpha-hydroxyl acid and adding crystalline alpha-hydroxyl acid, enabling complete dissolution while maintaining high bubbling capability
Solution Approach 2:
The patent creates a composite tablet formulation combining sodium bicarbonate, alpha-hydroxyl acid, and crystalline alpha-hydroxyl acid, where the components work synergistically to provide both complete solubility and sustained bubbling capability
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 provides improved oxygen saturation, blood circulation, skin whitening, brightening, and moisturizing effects by maintaining high bubbling capability and dissolving completely in skin water, while reinforcing skin barriers and increasing pore elasticity.
Implementation Method 1
The reaction is generally based on the following reaction: NaHCO3+gastric juice→NaHCO3+H+→Na++H2O+CO2↑
Implementation Method 2
skin water including carbonated water
Implementation Method 3
A buoyancy system is a form designed in such a manner that it floats at the top of gastric juice in the stomach by incorporating a bubble (frequently, CO2)-generating ingredient
