Solution Overview

Problem

Cosmetic compositions, particularly emulsions, face challenges in stability and sensorial profile due to complex ingredient interactions, with existing additives failing to improve stability and spreadability under varying conditions.

Innovation Solution

Incorporation of specific compounds of formula (I) that enhance the stability and sensorial profile of cosmetic formulations by forming smaller droplets, improving spreadability and foam stability without negative interactions with other ingredients.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the number of ingredients in cosmetic compositions is increased to address multiple issues, then the benefit and performance are improved, but the stability and risk of negative interactions between components increase

Engineering Contradiction:

ImproveperformanceVSAvoidstability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent applies multi-functionality by using a single compound (benzoic acid or furoic acid derivative) that simultaneously performs multiple functions: stabilizing emulsions against temperature variations, improving foam stability, and enhancing sensorial properties. This resolves the contradiction by reducing the total number of ingredients needed while maintaining or improving overall composition performance and stability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If the average particle size of droplets in emulsion is reduced to improve spreadability, then the sensorial profile is improved, but the complexity of formulation increases

Engineering Contradiction:

ImprovespreadabilityVSAvoidformulation complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent changes the physical-chemical parameters of the formulation by introducing benzoic acid or furoic acid derivatives, which modify the interfacial properties and droplet characteristics. This results in reduced average particle size and improved spreadability without requiring complex formulation strategies or multiple processing steps.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If cosmetic compositions are subjected to difficult storage conditions like high or low temperatures, then the test of stability is performed, but the emulsion stability deteriorates

Engineering Contradiction:

Improvestability testVSAvoidemulsion stability

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent applies beforehand cushioning by incorporating benzoic acid or furoic acid derivatives into the formulation before storage. These compounds preemptively stabilize the emulsion structure, protecting it against the adverse effects of temperature variations and other difficult storage conditions, thereby maintaining emulsion stability throughout the storage period.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)
