Solution Overview

Problem

Existing fragrance compositions lack a detailed understanding of the relationship between specific aldehyde compositions and their scents, limiting their effectiveness in enhancing the value of products such as fragrances, cosmetics, detergents, hygiene products, miscellaneous goods, and foods.

Innovation Solution

A specific aldehyde composition comprising aldehydes represented by Formulas (1) and (2) in a mass ratio of 97.00/3.00 to 99.999/0.001, optionally with ester (4) and/or alcohol (3) or sulfonic acid ester (5), providing a balanced scent of green, aldehyde, and floral notes, and enhancing diffusibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a conventional production method is used to obtain para-isobutyl dihydrocinnamic aldehyde, then a product containing 68-70% para isomer can be obtained, but the relationship between the composition and the scent has not been studied in detail and the scent balance is not optimized

Engineering Contradiction:

Improveisomer composition controlVSAvoidscent-characterization data

Core Design Contradiction:

Manufacturing precisionVSLoss of information

Solution Approach 1:

The patent changes the compositional parameters by establishing a specific mass ratio range between para-isobutyl dihydrocinnamic aldehyde (97.00-99.999%) and meta-isobutyl dihydrocinnamic aldehyde (3.00-0.001%), transforming the conventional 68-70% para isomer product into an optimized composition with enhanced scent characteristics

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent replaces the conventional production method that yields 68-70% para isomer with a new method achieving 97.00-99.999% para isomer, substituting the previous compositional outcome with a superior one that provides better scent balance and character

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of manufacture

If existing fragrance compositions are used, then products can be manufactured, but the scent balance and diffusibility are not optimized

Engineering Contradiction:

Improvefragrance composition availabilityVSAvoidscent performance

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent creates a composite fragrance composition by combining para-isobutyl dihydrocinnamic aldehyde with specific amounts of meta-isobutyl dihydrocinnamic aldehyde (0.01-2.0 mass%) and other fragrance components, achieving an optimized scent balance that is neither purely para nor purely meta isomer

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The patent applies local quality by giving different functional roles to different isomers within the composition: the para isomer (97.00-99.999%) provides the primary scent character while the meta isomer (0.01-2.0 mass%) enhances specific scent notes, creating a differentiated functional distribution within the mixture

Inventive Principle:

Principle #3Local quality

AI summary

An aldehyde composition, which includes an aldehyde represented by Formula (1) described below and an aldehyde represented by Formula (2) described below, and a mass ratio [(1)/(2)] between the aldehyde represented by Formula (1) and the aldehyde represented by Formula (2) is from 97.00/3.00 to 99.999/0.001. The aldehyde composition is useful as a fragrance since it has a scent excellent in balance of green, aldehyde, and floral. Further, a fragrance composition excellent in diffusibility can be obtained by containing the aldehyde composition
