Solution Overview

Problem

Water-soluble antioxidants like ascorbic acid are unstable in cosmetic formulations, leading to degradation issues and undesirable textures in skin care products, which existing anhydrous systems fail to address effectively.

Innovation Solution

A delivery system comprising an elastomer, first and second dispersants, and active ingredients such as ascorbic acid, which forms a stable, aesthetically pleasing gel formulation by using Dimethicone/Dimethicone crosspolymers, Cyclomethicone, and other silicone-based components to maintain the active's stability and functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If water-soluble antioxidants like ascorbic acid are incorporated into cosmetic formulations, then anti-aging and skin care functionality is improved, but stability and formulation reliability deteriorate due to rapid degradation

Engineering Contradiction:

Improvestability of ascorbic acidVSAvoidchemical stability

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent uses an intermediary delivery system comprising an elastomer matrix with dispersants to mediate between the unstable ascorbic acid and the formulation environment. This intermediary system protects ascorbic acid from rapid degradation while maintaining its functionality, resolving the contradiction between stability and reliability.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the physical and chemical parameters of ascorbic acid by incorporating it into an anhydrous elastomer-based formulation rather than water-soluble systems. This parameter change (from aqueous to non-aqueous environment) significantly improves stability while preserving anti-aging effects.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If ascorbic acid is formulated into skin care products, then anti-aging functionality is improved, but texture and aesthetics worsen due to sandy feel

Engineering Contradiction:

Improvefunctionality of ascorbic acidVSAvoidskin feel

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent changes the physical state and delivery mechanism by using an anhydrous elastomer-based gel system instead of water-based formulations. This parameter change eliminates the sandy texture associated with crystalline ascorbic acid while maintaining its biological functionality.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite material system combining elastomer, dispersant, and ascorbic acid. This composite formulation provides smooth skin feel through the elastomer matrix while delivering the active ingredients, resolving the contradiction between functionality and texture.

Inventive Principle:

Principle #40Composite materials

3Stability of the object's composition

If anhydrous systems are used to incorporate ascorbic acid, then stability is improved, but skin care aesthetics and ease of application worsen

Engineering Contradiction:

Improvestability of ascorbic acidVSAvoidaesthetics of skin care product

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent optimizes the physical parameters of the anhydrous system by selecting specific elastomers and dispersants that create a gel formulation with appropriate viscosity and spreadability. This parameter optimization maintains stability while improving aesthetics and ease of application.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent develops a composite anhydrous system combining elastomer, dispersant, and ascorbic acid in specific ratios. This composite formulation achieves both stability and cosmetically acceptable properties, resolving the contradiction between stability and ease of operation.
