Anhydrous Keratin Composition for Matte, Lightweight Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic compositions for caring for and making up keratin materials, such as lips, face challenges in providing easy application, matte deposit, and a lightweight sensation, often resulting in greasiness and inadequate coverage.
Innovation Solution
An anhydrous composition comprising organopolysiloxane elastomer powder coated with silicone resin, organopolysiloxane elastomer in a first oil, fillers like polymethylsilsesquioxane and calcium aluminum borosilicate, and a volatile hydrocarbon oil, without wax, to achieve a matte deposit and lightweight sensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If liquid compositions without waxes comprising nonvolatile oils with molecular weight greater than 600 g/mol are used, then the composition is easy to apply, but the deposited layers exhibit a glossy feeling and greasiness on the lips
Solution Approach 1:
The patent changes the physical and chemical parameters of the oil phase by using volatile hydrocarbon oils with specific molecular weights (100-300 g/mol) instead of high molecular weight oils, and controls the volatility and evaporation characteristics to achieve matte finish while maintaining application ease
Solution Approach 2:
The patent creates a composite formulation combining volatile hydrocarbon oils with specific elastomers (silicone-based and non-silicone), fillers, and pigments to achieve a synergistic effect that provides both easy application and matte non-greasy finish
2Object-generated harmful factors
If compositions with waxes are used, then a matte deposit can be achieved, but the application becomes difficult and the texture is heavy
Solution Approach 1:
The patent extracts and eliminates waxes from the formulation entirely, replacing their matte-forming function with a combination of volatile oils and specific elastomers that provide matte finish without the heaviness and application difficulty associated with waxes
Solution Approach 2:
The patent uses volatile hydrocarbon oils that evaporate after application, providing temporary matte finish and texture control during application, then disappear to leave a lightweight, non-greasy feel without the persistent heaviness of wax-based systems
3Quantity of substance
If compositions with high filler content are used, then good coverage is achieved, but the texture becomes heavy and application becomes difficult
Solution Approach 1:
The patent optimizes the particle size, shape, and surface treatment of fillers, and adjusts their size distribution to maintain high coverage while ensuring the formulation remains lightweight and easy to apply
Solution Approach 2:
The patent uses different types of fillers with different properties (inorganic and organic, spherical and irregular shapes) to provide coverage in different areas and at different depths, achieving good coverage without uniform heaviness throughout the formulation
