Silicone-Polyurethane Polymer Lip Makeup for Transfer-Resistant Matte Finish
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lip care and make-up products struggle to provide a homogeneous, comfortable, and long-lasting matte deposit on the lips without drying or transferring, especially when in contact with fabrics or materials.
Innovation Solution
A cosmetic composition comprising a silicone/polyurethane polymer with at least 17.5% active material content, combined with linear or branched C8-C19 alkanes and hydrophobic treated silica powder, which forms a stable and transfer-resistant matte film on the lips.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If volatile oils and fillers are used to provide matte effect, then matte appearance is achieved, but composition stability is impacted and deposit has drying appearance
Solution Approach 1:
The patent changes the chemical composition parameters by using silicone/polyurethane polymer instead of traditional volatile oils, and employs hydrophobically treated silica powder with specific surface treatment to achieve matte effect without compromising composition stability
Solution Approach 2:
The patent creates a composite system combining silicone/polyurethane polymer with hydrophobically treated silica powder, where the hydrophobic treatment on silica surface modifies the interaction between components, achieving both matte appearance and composition stability
2Shape
If volatile oils and fillers are used to provide matte effect, then matte appearance is achieved, but deposit has drying appearance on lips
Solution Approach 1:
The patent modifies the physical and chemical parameters of the matte-forming components by using silicone/polyurethane polymer and hydrophobically treated silica, changing the deposit properties to eliminate drying appearance while maintaining matte effect
Solution Approach 2:
The patent converts the typically drying effect of matte agents into a beneficial outcome by using hydrophobically treated silica powder that provides matte appearance while preventing moisture loss and avoiding drying appearance on lips
3Shape
If high content of silicone/polyurethane polymer is used (≥17.5% active material), then matte performance and transfer resistance are improved, but composition stability may be compromised without silicone resin
Solution Approach 1:
The patent optimizes the concentration parameter of silicone/polyurethane polymer at ≥17.5% active material and adjusts the hydrophobic treatment on silica powder to achieve both high matte performance and composition stability without requiring silicone resin
Solution Approach 2:
The hydrophobically treated silica powder acts as an intermediary component that enables high polymer content formulations to remain stable by modifying surface interactions and preventing phase separation
4Shape
If traditional matte agents are used, then matte effect is achieved, but transfer resistance to fabric is insufficient
Solution Approach 1:
The patent develops a composite formulation combining silicone/polyurethane polymer with hydrophobically treated silica powder, creating a synergistic system that provides both matte effect and superior transfer resistance to fabric and materials
