Translucent Cosmetic Composition Ceramide Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cosmetic formulations containing ceramides often suffer from stability issues and a heavy feeling of use due to precipitation and foreign matter, making it difficult to achieve a light and comfortable application.
Innovation Solution
A translucent emulsified gel cream formulation incorporating ceramides or their derivatives, a gelling agent like isostearyl alcohol*butylene glycol cocoate*ethyl cellulose, and an oil, which stabilizes the ceramide and provides a light feeling of use without foreign matter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ceramides are contained in a large amount in cosmetic formulations, then the skin protection function is improved, but the formulation stability deteriorates and precipitation phenomena occur
Solution Approach 1:
The patent uses an emulsifier as an intermediary substance to mediate between ceramides and the aqueous phase. The emulsifier forms micelles that solubilize ceramides, preventing direct contact and aggregation between ceramide molecules, thus maintaining formulation stability while delivering adequate ceramide content for skin protection.
Solution Approach 2:
The patent changes the physical state and solubility parameters of ceramides by incorporating them into emulsion systems. By controlling the emulsification process and selecting appropriate emulsifiers, the ceramides are transformed from an insoluble state that causes precipitation to a solubilized state within micelles, resolving the stability issue while maintaining functional effectiveness.
2Quantity of substance
If ceramides are included in the cosmetic formulations in hard capsule form, then the ceramide content is maintained, but foreign matters are generated and a heavy feeling of use occurs
Solution Approach 1:
The patent fundamentally changes the physical form and delivery mechanism of ceramides. Instead of using hard capsules that require mechanical breakdown and leave residue, the ceramides are incorporated into an emulsified gel cream formulation where they are pre-dispersed at the molecular level within micelles, providing a smooth, lightweight application feel while maintaining adequate ceramide content.
Solution Approach 2:
The patent creates a composite formulation system combining ceramides with emulsifiers, gelling agents, and other cosmetic ingredients. This composite emulsion structure allows ceramides to be delivered in a form that integrates seamlessly with the skin, eliminating the foreign matter sensation associated with capsule-based delivery while preserving ceramide quantity and efficacy.
3Reliability
If ceramides are supplied externally through cosmetics, then the skin protection function is improved, but the formulation becomes unstable and precipitation occurs
Solution Approach 1:
The emulsifier acts as a mediator between the hydrophobic ceramides and the hydrophilic aqueous phase. By forming micellar structures, the emulsifier allows ceramides to be delivered externally without direct interaction with water that would cause precipitation, thus maintaining both skin protection function and formulation stability.
Solution Approach 2:
The patent utilizes phase transition principles by forming an emulsion system where ceramides are held in a dispersed phase within micelles. This phase-separated structure prevents ceramide crystallization and precipitation while allowing controlled delivery to the skin, maintaining both stability and protective function.
