Lip Makeup Composition With Gloss and Lasting Properties
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lip makeup products require a two-step process to achieve both color-lasting and glossy effects, which is inconvenient and results in a thicker film, whereas there is a need for a single-step solution that provides homogeneous, long-lasting color and high gloss.
Innovation Solution
A cosmetic composition combining silicone-polyurethane polymer, linear or branched C8-C19 alkanes, and phenyl silicone oils with a refractive index greater than 1.45, optionally with pigments, to create a single-step, anhydrous, translucent or transparent solution that applies as a single layer, offering immediate and lasting gloss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a two-step process is used to achieve both color-lasting and glossy effects, then the desired dual effect is obtained, but the application process becomes complex and the film thickness increases
Solution Approach 1:
The patent combines the base coat and top coat into a single integrated composition that simultaneously provides both color-lasting and glossy effects. This is achieved by formulating a homogeneous mixture containing film-forming polymers (for color retention), pigments (for color), and gloss-providing agents (for shine), eliminating the need for separate application steps while maintaining both functional benefits.
Solution Approach 2:
The single-step composition is designed to perform multiple functions simultaneously: it acts as both a base coat (providing color and adherence) and a top coat (providing gloss and protection). The formulation integrates components that fulfill both roles, allowing one product to replace two previously separate products and simplify the application process.

3Ease of operation
If a single-step composition is used, then the application process is simplified and film thickness is reduced, but achieving both color-lasting and gloss effects simultaneously is difficult
Solution Approach 1:
The patent employs a composite formulation that integrates multiple functional components into a single homogeneous composition. This includes film-forming polymers for color retention, pigments for coloration, and gloss-providing agents such as silicones or esters for shine. The composite nature of the formulation allows all these components to work synergistically in one application step, delivering both color-lasting and glossy effects simultaneously without compromising performance.
