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

VSEngineering 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

Engineering Contradiction:
Improveformulation stabilityVSAvoidshelf life
Core Design Contradiction:
Stability of the object's compositionVSDuration of action of stationary object

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.

Inventive Principle:
Principle #35Parameter changes

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.

Inventive Principle:
Principle #40Composite materials

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

Engineering Contradiction:
Improveskin toleranceVSAvoidskin irritation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

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.

Inventive Principle:
Principle #24Intermediary (Mediator)
