Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Cosmetic compositions for keratin materials often fail to achieve a uniform, cohesive, and non-tacky film with long-lasting gloss and staying power, as existing crosslinked oils tend to be viscous and transfer onto the fingers.

Innovation Solution

A composition comprising a compound formed by reacting an oil with nucleophilic or electrophilic reactive functions and a junction group capable of establishing hydrogen bonds, specifically using ureidopyrimidone groups to enhance crosslinking and improve the cosmetic effect, resulting in a solid form that is non-tacky and transfer-resistant.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If crosslinked oils (e.g., castor oil functionalized with IPDI) are used to improve staying power and gloss, then the deposit gains long-lasting effect and gloss, but the deposit becomes tacky and transfers onto fingers

Engineering Contradiction:

Improvestaying powerVSAvoidtackiness and transfer

Core Design Contradiction:

Duration of action of moving objectVSObject-generated harmful factors

Solution Approach 1:

The patent changes the chemical structure parameters of the crosslinking agent by selecting specific junction groups (ureidopyrimidone, triazene, triazole, tetrazole) with particular hydrogen bonding capabilities. These structural modifications to the crosslinking mechanism resolve the contradiction by achieving strong adhesion without the tackiness associated with conventional IPDI crosslinked oils

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite system combining oils with nucleophilic/electrophilic reactive functions and specific junction groups capable of hydrogen bonding. This composite approach integrates multiple functional components that work synergistically to provide both the desired staying power and the elimination of tackiness that cannot be achieved with single-component crosslinked oils

Inventive Principle:

Principle #40Composite materials

2Duration of action of moving object

If conventional crosslinked oils are used to achieve gloss and staying power, then the cosmetic effect is enhanced, but the film becomes non-uniform and non-cohesive

Engineering Contradiction:

Improvestaying powerVSAvoidfilm uniformity and cohesion

Core Design Contradiction:

Duration of action of moving objectVSStability of the object's composition

Solution Approach 1:

The patent modifies the chemical parameters of the crosslinking system by introducing junction groups with specific hydrogen bonding characteristics (capable of forming at least 3 hydrogen bonds). This changes the crosslinking mechanism from conventional covalent bonding to hydrogen bonding-dominated assembly, resulting in uniform and cohesive film formation while maintaining long-lasting effects

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The junction groups act as intermediary structures that mediate between the oil molecules and the keratin substrate. These intermediaries with specific hydrogen bonding capabilities facilitate uniform distribution and cohesive assembly of the deposit, resolving the non-uniformity issue while maintaining the desired staying power

Inventive Principle:

Principle #24Intermediary (Mediator)

3Illumination intensity

If oils with high carbon number esters or polybutenes are used to achieve gloss, then the glossy effect is improved, but the staying power and transfer resistance are insufficient

Engineering Contradiction:

ImproveglossVSAvoidstaying power

Core Design Contradiction:

Illumination intensityVSDuration of action of moving object

Solution Approach 1:

The patent merges two previously separate functions into a single integrated system: the glossy oil component and the crosslinking agent. By combining oils with reactive functions and junction groups in one molecule, the composition simultaneously achieves gloss (from the oil component) and staying power (from the hydrogen bonding crosslinking), eliminating the need to choose between these properties

Inventive Principle:

Principle #5Merging (Combining)
