Gel-Gel Cosmetic Composition for Soft-Focus Skin Masking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cosmetic compositions for masking skin imperfections, such as pores, wrinkles, and fine lines, do not adequately provide a soft-focus effect while maintaining good cosmetic properties like being soft, fresh, and light on application.
Innovation Solution
A cosmetic composition comprising a macroscopically homogeneous mixture of a gelled aqueous phase with synthetic polymeric hydrophilic gelling agents and a gelled oily phase with lipophilic gelling agents, along with soft-focus fillers like acrylic copolymer powders and organopolysiloxane elastomers, to create a gel-gel architecture that enhances the soft-focus effect and provides a comfortable application sensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If soft-focus fillers are added to cosmetic compositions to mask skin imperfections, then the soft-focus effect is improved, but the cosmetic properties such as softness, freshness, and lightness deteriorate
Solution Approach 1:
The patent uses a composite gel-gel architecture combining hydrophilic gel phase and lipophilic gel phase, each containing specific gelling agents and soft-focus fillers. This composite structure allows the fillers to be effectively distributed and fixed within the gel network, providing strong soft-focus effect while the gel phases maintain the composition's softness, freshness, and lightness through their specific rheological properties
Solution Approach 2:
The patent specifies precise parameter ranges for gelling agents (hydrophilic gelling agent at 0.1-10% by weight, lipophilic gelling agent at 1-20% by weight) and soft-focus fillers (0.5-30% by weight) to optimize both the soft-focus effect and cosmetic properties. By controlling these parameters within specific ranges, the composition achieves the desired balance between masking skin imperfections and maintaining pleasant application sensations
2Ease of manufacture
If conventional emulsion formulations are used, then the composition is easy to manufacture, but the soft-focus performance is insufficient
Solution Approach 1:
The patent divides the formulation into two distinct gel phases: a hydrophilic gel phase containing water-soluble gelling agents and soft-focus fillers, and a lipophilic gel phase containing oil-soluble gelling agents and additional soft-focus fillers. This segmentation allows each phase to be optimized independently for its specific function while maintaining overall formulation simplicity and achieving superior soft-focus performance through the synergistic combination of both phases
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
The composition effectively hides skin imperfections with a soft-focus effect, offering a fresh and light sensation while maintaining ease of application, and does not require surfactants for stability, ensuring long-lasting consistency.
