Jasmonic Acid Derivative Emulsion Stability via Siloxane Elastomer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Jasmonic acid derivatives, such as sodium tetrahydrojasmonate, are challenging to formulate into stable emulsions due to their high electrolyte content and amphiphilic characteristics, leading to texture and stability issues in anti-aging compositions.
Innovation Solution
A stable anti-aging composition is developed with an aqueous phase containing at least one jasmonic acid derivative and an oil phase including dimethicone and an emulsifying crosslinked siloxane elastomer, which converts into droplets upon application of force, allowing effective penetration into keratinous substrates like skin, hair, or nails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If high concentrations of jasmonic acid derivatives are incorporated into an emulsion, then anti-aging efficacy is improved, but phase separation occurs due to high electrolyte content and amphiphilic characteristics
Solution Approach 1:
The patent introduces an intermediary oil phase containing dimethicone and emulsifying crosslinked siloxane elastomer that mediates between the aqueous phase (containing jasmonic acid derivative) and the external environment. This intermediary phase prevents direct interaction between the electrolyte-containing aqueous phase and other components, thereby preventing phase separation while allowing high concentrations of jasmonic acid derivative to be carried in the aqueous phase.
Solution Approach 2:
The patent changes the physical-chemical parameters of the emulsion system by adjusting the phase ratio (aqueous phase to oil phase from about 3 to about 12), the concentration of dimethicone (1% to 25%), and the concentration of emulsifying crosslinked siloxane elastomer (0.1% to 20%). These parameter changes optimize the balance between carrying high concentrations of jasmonic acid derivative and maintaining emulsion stability.
2Quantity of substance
If the emulsion is designed to be stable and non-separating, then carry capacity for jasmonic acid derivative is improved, but tactile pleasure and water-releasing effect are reduced
Solution Approach 1:
The patent applies dynamics by designing the emulsion to transition from a stable, non-separating state during storage and application to a water-releasing state upon mechanical stimulation. The emulsifying crosslinked siloxane elastomer enables the emulsion to maintain stability under normal conditions but release water and form droplets when subjected to shear force from rubbing or mechanical cleansing devices, thus providing both stability and tactile pleasure.
Solution Approach 2:
The patent utilizes phase transitions by designing the emulsion to remain in a stable emulsion phase during storage and initial application, then transition to a water-releasing phase containing droplets upon mechanical stimulation. This phase transition allows the emulsion to first provide stable carrier capacity and then release water and active ingredients upon user interaction, enhancing both carry capacity and tactile pleasure.
