Solution Overview

Problem

Existing musk fragrance compounds, such as Muscone, are poorly biodegradable and have limited water solubility, which affects their stability and sustainability in perfumery applications.

Innovation Solution

Development of novel oxa-macrocyclic fragrance compounds with a musk-based note, specifically designed to have improved biodegradability, chemical stability, and water solubility, as described by the general formula (I).

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional musk compounds like Muscone are used, then intense musk odor is achieved, but biodegradability is poor and water solubility is limited

Engineering Contradiction:
ImprovebiodegradabilityVSAvoidenvironmental persistence
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent applies parameter changes by modifying the chemical structure of musk compounds - specifically introducing oxygen atoms into the macrocyclic ring system to create oxa-macrocyclic structures. This structural modification changes the biodegradability parameter while maintaining the desired musk odor properties, resolving the contradiction between intense odor and poor biodegradability

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention creates composite molecular structures by combining carbonyl groups with oxygen-containing macrocyclic rings. This composite approach allows the molecule to exhibit both the intense musk odor characteristic of traditional musks and the improved biodegradability enabled by the oxygen-containing structure

Inventive Principle:
Principle #40Composite materials

2Reliability

If traditional musk compounds are used, then characteristic musk odor is achieved, but water solubility is limited affecting stability

Engineering Contradiction:
Improvechemical stabilityVSAvoidwater solubility
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent changes the chemical parameters by introducing oxygen atoms at specific positions in the macrocyclic ring (creating oxa-macrocyclic structures). This parameter modification enhances water solubility while simultaneously improving chemical stability, as the oxygen-containing structure allows for better hydration and reduced aggregation

Inventive Principle:
Principle #35Parameter changes

3Ease of manufacture

If synthetic substances with intense musk odor are developed, then fragrance intensity is improved, but chemical stability may be compromised

Engineering Contradiction:
Improvefragrance intensityVSAvoidchemical stability
Core Design Contradiction:
Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The patent applies local quality by strategically placing oxygen atoms at specific positions within the macrocyclic ring system rather than uniformly modifying the entire structure. This localized modification allows the molecule to maintain chemical stability in most regions while gaining improved solubility and controlled biodegradability at the oxygen-containing sites, achieving intense fragrance with maintained stability

Inventive Principle:
Principle #3Local quality
