Solution Overview

Problem

Existing gels based on mineral oils have a fossil origin and stringy texture, while gels based on vegetable oils suffer from poor compatibility with gelling agents and instability due to oxidation, necessitating the use of antioxidants.

Innovation Solution

A gelled composition comprising at least 50% biodegradable hydrocarbon oil with 90-100% isoparaffins content and 0.5-50% gelling agents, primarily selected from polymers or non-polymeric agents, providing stable and compatible formulations without the need for antioxidants.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If mineral oils are used as the base for gelled composition, then good compatibility with gelling agents is achieved, but the product has stringy texture and fossil origin

Engineering Contradiction:
Improvecompatibility with gelling agentsVSAvoidstringy texture and fossil origin
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The invention changes the chemical composition parameters of the oil phase by using isoparaffins (90-100% content) instead of traditional mineral oils, while maintaining the non-polar characteristics needed for gel formation. This parameter change eliminates the stringy texture and fossil origin issues while preserving compatibility with gelling agents.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention creates a composite system combining bio-based isoparaffins with specific gelling agents (polyisobutene, polydecene, or isoprene copolymers) to achieve both the desired texture and stability. This composite approach allows optimization of both compatibility and cosmetic properties.

Inventive Principle:
Principle #40Composite materials

2Object-affected harmful factors

If vegetable oils are used as the base for gelled composition, then bio-based origin is achieved, but poor compatibility with copolymers and oxidation instability occur

Engineering Contradiction:
Improvebio-based originVSAvoidcompatibility with copolymers and oxidation stability
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The invention modifies the chemical structure parameters by using hydrogenated and isomerized vegetable oils to produce isoparaffins with saturated hydrocarbon chains. This eliminates the unsaturated bonds that cause oxidation in traditional vegetable oils while maintaining the bio-based origin and improving compatibility with gelling copolymers.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention uses isoparaffins as an intermediary substance that bridges the gap between the desirable bio-based origin of vegetable oils and the stability/compatibility of mineral oils. The isoparaffins retain the renewable character while achieving the chemical stability needed for cosmetic formulations.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of manufacture

If esters are used as the base for gelled composition, then chemical origin is achieved, but poor compatibility with copolymers occurs

Engineering Contradiction:
Improvechemical originVSAvoidcompatibility with copolymers
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The invention changes the functional group parameters by replacing ester groups with hydrocarbon chains through hydrogenation and isomerization processes. This parameter change maintains the synthetic/chemical origin advantage while dramatically improving compatibility with gelling copolymers by eliminating polar ester groups that interfere with polymer-gel network formation.
