Solid Emulsion Makeup Primer With Silica for Blur and Transparency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing makeup compositions often compromise on desirable attributes such as transparency, lightweight feel, blurring, oil control, and makeup wear, while also failing to address environmental sustainability concerns.
Innovation Solution
A makeup composition comprising a solid emulsion with a fatty continuous phase containing C15-C19 alkane and silica, along with a silicone emulsifier, is developed, which is free of UV-absorbing composite particles and supramolecular polymers, promoting renewable and natural materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a primer is used to provide blurring, then skin appearance is improved, but transparency on skin deteriorates or lightweight feel is compromised
Solution Approach 1:
The patent changes the physical and chemical parameters of the emulsion system, specifically using a solid emulsion with fatty continuous phase containing C15-C19 alkane and silica particles. The refractive index matching between oil phase and water phase creates optical blurring without opacity, resolving the contradiction between blurring effect and transparency.
Solution Approach 2:
The patent employs a composite emulsion system combining fatty continuous phase, silica particles, and silicone emulsifier. This composite structure provides blurring through refractive index manipulation while maintaining transparency by avoiding traditional opaque pigments and UV-absorbing composite particles, thus resolving the transparency-blurring contradiction.
2Reliability
If a setting product is applied to enhance makeup wear, then durability is improved, but oil-absorbing ability deteriorates
Solution Approach 1:
The patent incorporates silica particles which provide porous structure capable of absorbing excess oil while maintaining makeup adhesion. This resolves the contradiction by enabling both durability through emulsion bonding and oil control through silica's absorbent properties.
Solution Approach 2:
The setting product is formulated with localized functional components: the emulsion base provides wear enhancement while silica particles are distributed to specifically target oil control zones. This local quality differentiation allows simultaneous achievement of durability and oil management without mutual interference.
3Ease of manufacture
If traditional cosmetic ingredients are used to achieve desired performance, then product functionality is improved, but environmental sustainability deteriorates
Solution Approach 1:
The patent reformulates cosmetic ingredients by changing their origin parameters - replacing petrochemical-derived components with renewable plant-based alternatives. This includes using plant-derived fatty acids, waxes, and emulsifiers, maintaining product performance while improving environmental sustainability and reducing carbon footprint.
Solution Approach 2:
The patent extracts and eliminates harmful components from traditional formulations, specifically removing UV-absorbing composite particles and supramolecular polymers. This extraction approach maintains essential product functionality while removing environmentally problematic substances, resolving the contradiction between performance and sustainability.
