Lip Compositions Forming Multilayer Structure via Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lip compositions, particularly lip glosses, lack good transfer-resistance and application properties such as slip, shine, and matte characteristics, necessitating a multi-step application process to achieve desired cosmetic effects.
Innovation Solution
Development of lip compositions comprising at least two components, including a semi-crystalline acrylate copolymer, that form a multilayer structure upon application, providing improved adhesion, transfer-resistance, and cosmetic properties like shine and matte finishes without requiring a multi-step application process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single-step lip composition is used, then application simplicity is improved, but transfer-resistance and cosmetic properties (shine, gloss, matte) deteriorate
Solution Approach 1:
The lip composition is divided into at least two separate components (e.g., a first component and a second component) that are applied in sequence. The first component forms a base layer with good adhesion and transfer-resistance, while the second component provides cosmetic properties such as shine, gloss, or matte finish. This segmentation allows each component to be optimized for its specific function while maintaining overall simplicity in the application process.
Solution Approach 2:
Multiple functional layers are merged into a single composition system that can be applied in one step. The composition comprises at least two components that work together to provide both transfer-resistance and cosmetic properties simultaneously, eliminating the need for separate multi-step application processes while achieving the benefits of layered construction.
2Ease of operation
If a single-step lip composition is used, then application simplicity is improved, but adhesion and slip properties deteriorate
Solution Approach 1:
The composition is segmented into a first component that specifically provides adhesion and a second component that provides slip and cosmetic properties. This allows each component to be formulated with its optimal properties without compromise, while the combination remains simple to apply in one step.
Solution Approach 2:
Different regions of the lip composition provide different functions: the first component is optimized for adhesion to the lip surface, while the second component is optimized for slip and cosmetic appearance. This local differentiation of properties within the single-step composition resolves the contradiction between application simplicity and functional performance.
3Ease of operation
If a single-step lip composition is used, then application simplicity is improved, but cosmetic appearance properties (shine, gloss, matte) deteriorate
Solution Approach 1:
The composition is divided into a first component that provides base adhesion and a second component that is specifically formulated to provide desired cosmetic appearance properties such as shine, gloss, or matte finish. This segmentation ensures that cosmetic properties are not compromised while maintaining single-step application simplicity.
Solution Approach 2:
The lip composition uses a composite material system comprising at least two components with different functional properties. The combination of these components creates a single-step application that delivers both good adhesion and enhanced cosmetic appearance properties, resolving the contradiction between application simplicity and aesthetic performance.
