Multilayer Cosmetic Resin Composition for Wear and Shine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic compositions struggle to achieve both long-wear/transfer-resistance properties and good application, comfort, and appearance properties, such as shine or matte properties, often requiring multiple application steps and frequent reapplication.
Innovation Solution
Anhydrous cosmetic compositions that form a multilayer structure after application, comprising at least two immiscible components and a combination of modified MQ resin, MQ resin, and polypropylsilsesquioxane resin, which separate to form distinct layers providing enhanced properties without the need for multiple application steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If MQ resin is used to provide long wear properties and transfer-resistance, then wear resistance is improved, but application properties and appearance properties deteriorate
Solution Approach 1:
The cosmetic composition is segmented into multiple immiscible phases (oil phase and silicone resin phase) that remain separate in the container but can be temporarily mixed during application. This allows different functional components to be delivered simultaneously without compromising application properties, as each phase can be optimized independently for its specific function.
Solution Approach 2:
The invention uses a composite system combining multiple silicone resins (MQ resin and polypropylsilsesquioxane resin) with different properties. The MQ resin provides wear resistance while the polypropylsilsesquioxane resin improves application properties and shine, creating a composite material that delivers both long-wear performance and good application characteristics.
2Reliability
If MQ resin is used to provide long wear properties, then transfer-resistance is improved, but shine and gloss properties deteriorate
Solution Approach 1:
Different phases of the composition are designed to provide different local qualities: the oil phase provides shine and gloss properties for appearance, while the silicone resin phase provides transfer-resistance for durability. Both qualities coexist in the final product without compromising either function.
Solution Approach 2:
The composite system combines MQ resin (for transfer-resistance) with polypropylsilsesquoxane resin and oil phase components (for shine and gloss), creating a multi-functional material that simultaneously achieves both transfer-resistance and desirable appearance properties.
3Illumination intensity
If a topcoat composition is applied separately to improve application properties and shine, then appearance properties are improved, but the number of application steps increases
Solution Approach 1:
The invention merges the base composition and topcoat composition into a single unified product. The immiscible phases are formulated to separate in the container but mix temporarily during application, delivering both the protective long-wear base layer and the cosmetic-enhancing topcoat layer in one application step, thereby eliminating the need for separate topcoat application.
Solution Approach 2:
The single cosmetic composition performs multiple functions simultaneously: it provides long-wear protection, transfer-resistance, shine, gloss, and good application properties all in one product, eliminating the need for multiple specialized products and application steps.
4Illumination intensity
If a topcoat composition is reapplied continually to maintain appearance properties, then shine and gloss are maintained, but the long-wear benefit is reduced
Solution Approach 1:
The composition is formulated to provide continuous, sustained performance of both wear-resistance and appearance properties through its immiscible phase system. The phases work synergistically throughout the wear period, maintaining both protective and cosmetic functions simultaneously without requiring reapplication, thereby achieving true long-wear duration.
