Lip Cosmetic Composition Balancing Gloss and Color Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lip makeup products struggle to achieve both improved glossiness and reduced color smudging while maintaining moisture and avoiding matte expression, as conventional wax-based or powder-based thickening agents cause dryness and matte appearance.
Innovation Solution
A cosmetic composition for lips using a hydrogenated styrene/isoprene copolymer as a non-wax-based thickening agent, combined with a VP/hexadecene copolymer as a gloss agent and a silsesquioxane resin as a coating agent, to enhance glossiness and reduce color smudging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wax-based or powder-based thickening agents are used, then color persistence is improved, but glossiness deteriorates and dryness is caused
Solution Approach 1:
The patent changes the chemical composition parameters by replacing traditional wax-based or powder-based thickening agents with a polymeric thickening agent comprising hydrogenated styrene/isoprene copolymer, VP/hexadecene copolymer, and silsesquioxane resin. This parameter change maintains color persistence while eliminating the matte effect and dryness caused by conventional agents.
Solution Approach 2:
The patent employs a composite polymeric thickening system combining three different polymer components (hydrogenated styrene/isoprene copolymer, VP/hexadecene copolymer, and silsesquioxane resin) to achieve synergistic effects. This composite material provides both color persistence and glossiness, resolving the contradiction between durability and aesthetic appearance.
2Illumination intensity
If non-volatile oils are increased to improve glossiness, then shine is enhanced, but color smudging increases
Solution Approach 1:
The patent changes the formulation approach by using a polymeric thickening agent system instead of relying on increased non-volatile oil content. This parameter change allows achieving glossiness through the polymeric structure and film-forming properties rather than through oil content, thereby preventing color smudging.
Solution Approach 2:
The polymeric thickening agent acts as an intermediary substance that provides the desired glossiness and film-forming properties without the negative effects of high non-volatile oil content. The polymer network structure mediates between the need for shine and the need to prevent color transfer.
3Reliability
If coating agents and powders are used to suppress smudging, then color persistence is improved, but visual dryness and matte expression are caused
Solution Approach 1:
The patent fundamentally changes the formulation parameters by replacing coating agents and powders with a polymeric thickening agent system. This parameter change maintains the color persistence function while eliminating the visual dryness and matte expression caused by particulate materials.
Solution Approach 2:
The patent extracts and removes the harmful components (coating agents and powders) from the formulation while retaining the essential function of color persistence through the polymeric thickening agent system. This extraction eliminates the cause of visual dryness and matte appearance.

AI summary
The present invention relates to a cosmetic composition for lips with improved glossiness and an improved degree of color smudging. More specifically, the present invention relates to a cosmetic composition for lips which contains a hydrogenated styrene/isoprene copolymer, a VP/hexadecene copolymer, and a silsesquioxane resin as active ingredients and thus has improved glossiness on the lips as well as suppressed color smudging, namely color transfer from the lips. The cosmetic composition for lips according to the present invention not only suppresses color smudging from the lips but also increases the gloss of a formulation and can thus improve rough and matte makeup expression of the lips, visual dryness, and the appearance of dead skin cells and wrinkles.
