Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Cosmetic compositions struggle to achieve a matte, smooth skin appearance while providing a comfortable and pleasant feel, as existing solutions often result in dryness, greasiness, or a tacky sensation, failing to reconcile moisturization and optical smoothing effectively.

Innovation Solution

An anhydrous composition combining 3-15% lipophilic gelling agents, 10-50% fillers with at least two different types, and 40-85% fatty phase, offering a novel sensory effect that is neither greasy nor tacky, providing a soft-focus effect and breathable skin finish.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If mineral or organic fillers are used to achieve soft-focus effect and matte skin appearance, then optical smoothing and matte effect are improved, but skin feel becomes dry and rough

Engineering Contradiction:

Improveoptical smoothing effectVSAvoidskin comfort

Core Design Contradiction:

Illumination intensityVSEase of operation

Solution Approach 1:

The patent combines multiple types of fillers (mineral and organic) in specific proportions to create a composite filler system that balances optical smoothing properties with skin comfort, avoiding the dry and rough feel associated with single-type fillers

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The patent optimizes the particle size distribution and concentration of fillers to achieve the desired optical effect while maintaining comfort, adjusting parameters such as filler size range and percentage composition

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If large content of fatty phase is used to provide moisturization and soft feel, then skin comfort and moisturization are improved, but skin becomes shiny and greasy

Engineering Contradiction:

Improveskin comfortVSAvoidskin shine

Core Design Contradiction:

Ease of operationVSIllumination intensity

Solution Approach 1:

The patent controls the fatty phase content within a specific range (40-85% by weight) and adjusts the type and proportion of fatty substances to provide moisturization without excessive shine, optimizing the balance between comfort and optical appearance

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent uses different types of fatty substances with varying properties (liquid oils, solid waxes, esters) in specific proportions to create localized functional zones within the composition that provide moisturization while controlling shine

Inventive Principle:

Principle #3Local quality

3Illumination intensity

If crosslinked silicones are used to achieve matte effect and soft-focus effect, then optical smoothing is improved, but skin feel becomes hot and greasy with mask effect

Engineering Contradiction:

Improvematte effectVSAvoidskin comfort

Core Design Contradiction:

Illumination intensityVSEase of operation

Solution Approach 1:

The patent combines crosslinked silicones with other filler types and fatty substances to create a composite system that reduces the hot and greasy feel while maintaining the matte and soft-focus effects, balancing optical properties with sensory comfort

Inventive Principle:

Principle #40Composite materials

4Illumination intensity

If filler content is increased to improve covering of imperfections and soft-focus effect, then optical smoothing and color coverage are improved, but composition becomes less comfortable and more tacky

Engineering Contradiction:

Improvecovering effectVSAvoidapplication comfort

Core Design Contradiction:

Illumination intensityVSEase of operation

Solution Approach 1:

The patent optimizes the total filler content and the ratio of different filler types to achieve adequate covering power while maintaining application comfort, adjusting parameters such as filler concentration and particle size distribution

Inventive Principle:

Principle #35Parameter changes

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 composition achieves a comfortable, stable, and pleasant skin finish that is matte and smooth, hiding imperfections and allowing skin to breathe, with immediate visual and tactile benefits, maintaining stability over time and temperature variations.

Implementation Method 1

comprising from 3% to 15% by weight of at least one lipophilic gelling agent, from 10% to 50% by weight of fillers and from 40% to 85% by weight of at least one fatty phase

Methodology Applied

Scientific EffectGel formation: Gel

Implementation Method 2

use mineral or organic fillers with a soft-focus effect which absorb fat, give an astounding 'photoshop' optical effect, and also a very soft feel

Methodology Applied

Scientific EffectAbsorption: Absorption (physical)

Implementation Method 3

fillers with a soft-focus effect which absorb fat, give an astounding 'photoshop' optical effect... optically smoothing the microrelief, filling wrinkles, hiding skin imperfections and better reflecting light

Methodology Applied

Scientific EffectLight scattering: Scattering
