Anhydrous Cosmetic Composition Mattifying Effect
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cosmetic compositions that provide a mattifying effect while maintaining skin comfort and a silky feel are lacking, as existing materials often result in a dry, rough texture or require high silicone elastomer content leading to a cakey texture.
Innovation Solution
An anhydrous cosmetic composition comprising hydrophobic silica particles, at least 10% PMMA particles, silicone oil, hydrocarbon oil, and a silicone elastomer, with a viscosity between 10 Pa·s and 1000 Pa·s, which enhances the matte finish without drying the skin and provides a silky texture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If soft-focus minerals or organic fillers are used to achieve mattifying effect, then the mattifying effect is improved, but the skin feel becomes dry and rough
Solution Approach 1:
The patent uses a composite system combining hydrophobic silica particles, PMMA particles, and silicone elastomers in specific ratios. This composite approach allows the formulation to achieve mattifying effects while maintaining skin comfort, as each component contributes different properties that complement each other and mitigate individual drawbacks.
Solution Approach 2:
The patent specifies precise parameter ranges for each ingredient (silica content at 5-50%, PMMA at 10-80%, silicone elastomer at 1-30%) and viscosity (10-1000 Pa·s). By optimizing these parameters, the formulation achieves the right balance between mattifying performance and skin feel, preventing the dry and rough texture associated with higher filler contents.
2Quantity of substance
If silicone elastomer content is increased to achieve mattifying effect, then the mattifying effect is improved, but the texture becomes dry and coarse (cakey)
Solution Approach 1:
The patent limits silicone elastomer content to 1-30% of the total composition and controls overall viscosity within 10-1000 Pa·s. This parameter optimization ensures sufficient mattifying effect while preventing the cakey, coarse texture that results from excessive elastomer content.
Solution Approach 2:
The formulation combines silicone elastomers with PMMA particles and hydrophobic silica in a balanced ratio. This composite approach distributes the mattifying function across multiple components, allowing lower individual elastomer content while maintaining overall effectiveness and avoiding coarse texture.
3Quantity of substance
If hydrophobic silica particles and PMMA particles are used to absorb sebum, then the mattifying effect is improved, but the composition may become too thick or unstable
Solution Approach 1:
The patent specifies hydrophobic silica at 5-50% and PMMA particles at 10-80%, with controlled viscosity (10-1000 Pa·s). These parameter ranges ensure adequate sebum absorption capacity while preventing the composition from becoming overly thick or unstable, maintaining proper spreadability and homogeneity.
