Solution Overview

Problem

The cosmetic industry faces challenges in meeting the demand for isododecane, a key component in long-lasting makeup, due to limited oil resources and environmental concerns. Additionally, existing methods for producing isododecane from natural raw materials are inefficient and costly.

Innovation Solution

A volatile mixture of alkanes is developed as a substitute for isododecane in cosmetic formulations. This mixture is obtained through a Guerbet alcohol reaction followed by dehydration and hydrogenation, using fatty alcohols from natural origin, and has a flash point below 55°C.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If isododecane is used as a key component in cosmetic formulations, then long-lasting and water-resistant performance is improved, but environmental pollution and resource depletion worsen

Engineering Contradiction:
Improvemakeup longevity and water resistanceVSAvoidenvironmental pollution and resource depletion
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the chemical composition parameters by replacing petrochemical isododecane with a volatile mixture of alkanes derived from renewable vegetable oils through hydrocracking. This substitution maintains the required volatility (flash point below 55°C) and performance characteristics while eliminating dependence on depleting oil resources and reducing environmental pollution.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention uses readily available vegetable oils as feedstock that can be sustainably replenished, replacing the finite petroleum-based isododecane. The volatile alkane mixture provides the necessary temporary performance in makeup products while being derived from renewable sources that can be continuously produced without depleting natural resources.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Object-affected harmful factors

If biological processes are used to produce isododecane from natural raw materials, then environmental sustainability is improved, but production cost and complexity worsen

Engineering Contradiction:
Improveenvironmental sustainabilityVSAvoidproduction cost and process complexity
Core Design Contradiction:
Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The patent extracts and utilizes the valuable volatile components naturally present in vegetable oils through hydrocracking, obtaining a mixture of light alkanes (C5-C12) that directly replaces isododecane. This approach eliminates the need for complex biological conversion processes while achieving environmental sustainability through renewable feedstock.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of using complex biological processes to create isododecane, the invention copies the desired properties (volatility, water resistance, longevity) using a simpler hydrocracking process applied to vegetable oils. The resulting volatile alkane mixture replicates the functional performance of isododecane through a more economically viable and environmentally friendly route.

Inventive Principle:
Principle #26Copying

3Ease of operation

If a volatile mixture of alkanes with flash point below 55°C is used, then ease of application and comfort are improved, but fire safety risks worsen

Engineering Contradiction:
Improveease of application and comfortVSAvoidfire safety risks
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent carefully controls the composition parameters of the volatile alkane mixture to maintain a flash point below 55°C for optimal application properties and comfort, while accepting and managing the inherent fire safety considerations through proper formulation and usage instructions.
