Multilayer Cosmetic Composition Resolving Wear and Feel Trade-off
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic compositions often fail to balance long-wear and transfer-resistance properties with good application properties, feel, shine, and matte characteristics, requiring multiple applications and maintenance.
Innovation Solution
A cosmetic composition forming a multilayer structure on keratinous materials, comprising Component A with a silicone- and/or hydrocarbon-containing film-forming agent and surface-treated pigments, and Component B with silicone compounds, achieving immiscibility to create distinct layers for enhanced wear and appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If silicon resin (MQ resin) is used to provide long wear properties and transfer-resistance, then wear resistance is improved, but application properties and feel become poor (rough texture, matte appearance)
Solution Approach 1:
The cosmetic composition is divided into two immiscible components: Component A containing the film-forming agent (providing wear resistance) and Component B containing silicone compounds (providing smooth feel and shine). This segmentation allows each component to perform its specialized function without compromising the other, resolving the contradiction between durability and application quality.
Solution Approach 2:
The invention creates a composite system by combining two immiscible components (A and B) in a single cosmetic product. Component A provides the functional benefits of silicon resins (long wear, transfer-resistance) while Component B provides the aesthetic benefits (shine, smooth feel). The composite structure enables both properties to coexist without requiring separate application steps.
2Ease of manufacture
If a topcoat composition is separately applied to improve shine and gloss properties, then appearance properties are improved, but the application process becomes multi-step and requires constant maintenance
Solution Approach 1:
The invention merges the base cosmetic composition and the topcoat composition into a single unified product. Component A serves as the base providing wear resistance, while Component B serves as the topcoat providing shine and smoothness. Both components are combined in one container and applied in a single step, eliminating the need for separate application steps and reducing maintenance requirements.
Solution Approach 2:
The single cosmetic composition performs multiple functions simultaneously: Component A provides long wear and transfer-resistance properties, while Component B provides shine, gloss, and smooth feel. This multi-functional design eliminates the need for separate specialized products and simplifies the application process.
3Duration of action of stationary object
If long-wearing/transfer-resistant properties are achieved, then durability is improved, but application properties and feel upon application become poor
Solution Approach 1:
The cosmetic composition is segmented into Component A (film-forming agent for durability) and Component B (silicone compounds for application quality). This segmentation allows the durable component to provide long-lasting wear resistance while the silicone component ensures smooth application and pleasant feel, resolving the contradiction between duration and ease of operation.
Solution Approach 2:
The invention uses a composite material system where Component A and Component B are immiscible but combined in a single product. The composite structure enables the durable film-forming component to work alongside the smooth-feel silicone component, achieving both long duration and good application properties simultaneously.
