Composite Cosmetic Particulates for Natural Skin Undertones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current foundation makeup products often result in an ashy, chalky, or mask-like appearance on skin, particularly for ethnic users, due to the masking of natural skin undertones, and require a large number of shades to accommodate various skin colors, leading to increased manufacturing costs and consumer confusion.
Innovation Solution
The use of composite particulates containing a colorant portion and a clear or translucent thermoplastic portion, which are applied to keratinous surfaces to enhance skin dimensionality and undertone appearance, reducing the need for multiple shades by providing a universal color match.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If foundation makeup contains significant amounts of titanium dioxide to provide excellent coverage, then coverage is improved, but the appearance becomes mask-like and unnatural
Solution Approach 1:
The patent applies local quality by using translucent spherical particulates with specific refractive indices (1.3-1.7) that selectively interact with light to enhance skin dimensionality and undertone appearance in specific areas, rather than uniformly masking the entire skin surface. This allows coverage where needed while preserving natural skin appearance in other areas.
Solution Approach 2:
The invention uses composite materials by combining translucent spherical particulates (made from materials like silica, polymethylmethacrylate, or titanium dioxide with controlled refractive indices) with foundation makeup components. This composite structure provides both coverage and optical enhancement properties, reducing the mask-like appearance while maintaining concealment effectiveness.
2Adaptability or versatility
If a large number of foundation shades are formulated to match all skin colors, then color matching versatility is improved, but manufacturing cost and consumer confusion increase
Solution Approach 1:
The patent applies universality by formulating a single foundation base that can be adapted to multiple skin tones through the addition of translucent spherical particulates. These particulates with varying refractive indices can be adjusted in concentration and type to achieve different optical effects, allowing one foundation formula to serve multiple skin color ranges rather than requiring separate formulations for each shade.
Solution Approach 2:
The invention uses parameter changes by varying the refractive index of the spherical particulates (from 1.3 to 1.7) and their concentration in the foundation formula to achieve different optical effects and color matching outcomes. This allows a single base formulation to be adjusted across a wide range of skin tones by simply modifying particulate parameters rather than creating entirely different shade formulations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composite particulates improve the natural appearance of skin by reducing the ashy or chalky effect and allow for a wider range of skin tones to be matched with fewer shades, thereby reducing manufacturing costs and consumer confusion.
Implementation Method 1
when color cosmetics are formulated with certain types of composite particulates that have a portion of clear or translucent thermoplastic material in the particulate, that color cosmetics will exhibit improved appearance on skin, including an improved appearance of dimensionality, depth and skin undertones
Implementation Method 2
the composite particulates improve the natural appearance of skin by reducing the ashy or chalky effect

AI summary
A method for improving the appearance of skin depth, dimensionality or undertones by topically applying a composition containing composite particulates made by (a) solvating a clear or translucent thermoplastic material with solvent in an amount sufficient to swell the material; (b) combining the solvated mixture of (a) with one or more colorants; (c) removing the solvent to form a composite particulate, (d) formulating the composite particulate into a topical cosmetic composition for application to skin.
