Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing skin care formulations often suffer from instability during prolonged storage, leading to syneresis and reduced shelf life, while also causing skin irritation and requiring prolonged periods for skin tolerance to set in.
Innovation Solution
The development of skin care compositions that combine ethylhexyl palmitate and algae extract, which form a stable emulsion system, along with optional ingredients like encapsulated resveratrol and niacinamide, to enhance skin rejuvenation and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional skin care formulations are used, then skin rejuvenation effects can be achieved, but the formulations suffer from instability during prolonged storage, leading to syneresis and reduced shelf life
Solution Approach 1:
The patent changes the chemical parameters of the formulation by incorporating ethylhexyl palmitate (a fatty acid ester) and algae extract in specific concentrations (0.01-5% and 0.1-20% respectively). This parameter modification stabilizes the emulsion system, prevents syneresis, and extends shelf life while maintaining skin rejuvenation effects.
Solution Approach 2:
The patent creates a composite formulation combining ethylhexyl palmitate, algae extract, and optional ingredients like encapsulated resveratrol and niacinamide. This composite approach provides both immediate skin benefits and long-term stability, resolving the contradiction between efficacy and shelf life.
2Reliability
If existing skin care formulations are used, then skin conditions can be treated, but significant skin irritation occurs and prolonged periods are required for skin tolerance to set in
Solution Approach 1:
The patent uses ethylhexyl palmitate as an intermediary carrier that delivers active ingredients (algae extract, resveratrol, niacinamide) to the skin while minimizing irritation. This intermediary substance provides a gentle delivery mechanism that maintains reliability of treatment effects without causing significant skin irritation.
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
These compositions maintain stability under high temperatures and for extended periods, effectively reducing fine lines and wrinkles, improving the eye area, and maintaining skin moisture without causing significant skin irritation.
Implementation Method 1
The combination of ethylhexyl palmitate and algae extract provides a stable emulsion system that effectively delivers skin rejuvenating algae extract to the desired dermal layers
