Hydrating Cream Foundation Using Cellulose and Polar Polymer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cosmetic compositions often have poor application characteristics due to tackiness and lack of smooth feel, and rely on expensive ingredients or processing techniques to achieve hydrating and long-wearing properties.
Innovation Solution
A composition comprising a gelling agent such as cellulose derivatives, an oil-soluble polar modified polymer, and water, which provides moisturization and long-wearing properties without silicone resins or traditional film formers, offering a stable and comfortable texture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional film formers and silicone resins are used to achieve long-wearing properties, then transfer resistance is improved, but the composition becomes tacky and difficult to apply
Solution Approach 1:
The patent removes traditional film formers and silicone resins from the composition, extracting the problematic components that cause tackiness while maintaining long-wearing properties through alternative ingredients like cellulose derivatives and polar modified polymers
Solution Approach 2:
The patent uses a composite system combining cellulose derivatives (gelling agents) with polar modified polymers to achieve both smooth application and long-wearing performance, replacing the traditional silicone resin-based film-forming system
2Reliability
If expensive ingredients and processing techniques are used to achieve hydrating properties, then moisturization is improved, but manufacturing cost increases
Solution Approach 1:
The patent employs cost-effective cellulose derivatives and polar modified polymers instead of expensive hydrating ingredients, achieving moisturization through affordable, readily available materials that simplify manufacturing
Solution Approach 2:
The patent changes the chemical parameters of the composition by using polar modified polymers with specific polarity characteristics that provide hydrating effects through alternative mechanisms, eliminating the need for expensive traditional hydrating agents
3Strength
If silicone resins are used to impart transfer resistance, then wear resistance is improved, but the composition feels tacky and lacks smooth texture
Solution Approach 1:
The patent extracts silicone resins from the formulation, removing the source of tackiness while maintaining transfer resistance through the synergistic combination of cellulose derivatives and polar modified polymers that form a different type of protective film
Solution Approach 2:
The patent creates a composite system where cellulose derivatives provide structural integrity and the polar modified polymers provide smooth texture and transfer resistance, replacing the silicone resin-based system with a novel composite approach
