Minimalist Emulsion Composition for Sensitive Skin Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dermatocosmetic emulsions often irritate sensitive skin and fail to provide long-term moisturization while maintaining pleasant sensorial properties and storage stability.
Innovation Solution
A topical oil-in-water emulsion composition comprising water, panthenol, alkanediol, chelating agents, barrier-repairing agents, emollient esters, and soothing agents, with specific weight percentages and absence of certain irritating ingredients, which is storage stable and provides a pleasant skin sensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional emulsion ingredients (emulsifiers, stabilizers, emollients) are used to achieve pleasant sensorial properties and shelf stability, then the product texture and stability are improved, but skin irritation occurs in sensitive or compromised skin
Solution Approach 1:
The patent removes traditional emulsion ingredients (emulsifiers, stabilizers, emollients) that cause skin irritation while retaining the core water and oil/silicone phases. This extraction of harmful components eliminates skin irritation in sensitive and compromised skin while maintaining the basic emulsion functionality and shelf stability through alternative formulation approaches.
2Reliability
If traditional emulsion formulations are used to provide moisturization, then skin conditioning is improved, but the product causes skin redness and stinging reactions in compromised skin
Solution Approach 1:
The patent converts the potential harm of traditional emulsion ingredients into benefit by completely eliminating them from the formulation. Instead of using conventional emulsifiers and stabilizers that cause irritation, the formulation relies on the inherent stability of the water and oil/silicone phases combined with barrier-repairing agents that actively heal compromised skin, transforming a harmful formulation approach into a beneficial one for sensitive skin.
3Object-affected harmful factors
If minimalist formulation is used to eliminate irritating ingredients, then skin compatibility is improved, but achieving pleasant sensorial properties and storage stability becomes more difficult
Solution Approach 1:
The patent changes the formulation parameters by eliminating traditional emulsion ingredients (emulsifiers, stabilizers, emollients) and using only water, oil/silicone phases, and barrier-repairing agents. This parameter change simplifies the formulation while maintaining sensorial properties and storage stability through the inherent characteristics of the remaining components and their optimized concentrations.
