Method for releasing aldehyde or ketone
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fragrance and deodorizing technologies struggle with lingering fragrance intensity, volatility, and timing issues, leading to inconsistent fragrance release and ineffective deodorization, particularly against malodors caused by microorganisms, while antimicrobials disrupt skin flora and require high doses for efficacy.
Innovation Solution
A compound represented by formula (1) releases aldehydes or ketones through hydrolase action, enhancing lingering fragrance substantivity and deodorization, and a microorganism-mediated release of aldehydes or ketones mitigates malodor caused by microorganisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If compounded flavors or fragrances are used to enhance lingering fragrance, then fragrance substantivity is improved, but most flavor or fragrance components are washed away into water during cleaning, reducing lingering fragrance intensity
Solution Approach 1:
The patent applies preliminary action by incorporating flavor or fragrance components into cleaning components (surfactants) before use. The cleaning composition is designed to deposit flavor or fragrance onto substrates during the cleaning process itself, so that the fragrance is already in place before any washing occurs, preventing loss during the rinsing step
Solution Approach 2:
The patent uses cleaning components (surfactants) as intermediaries to carry and deposit flavor or fragrance components onto substrates. The surfactant acts as a vehicle that binds the fragrance to the substrate during cleaning, enabling the fragrance to remain on the substrate after rinsing rather than being washed away
2Object-affected harmful factors
If flavor or fragrance components are used for deodorization, then malodor is reduced, but high doses are required which may cause adverse effects
Solution Approach 1:
The patent applies self-service by designing cleaning compositions that automatically deposit flavor or fragrance components onto substrates during the normal cleaning process without requiring additional application steps. The composition itself carries out the deodorization function through the deposited fragrance, eliminating the need for separate high-dose deodorizing treatments
Solution Approach 2:
The patent changes the parameter of fragrance delivery from post-cleaning application to in-situ deposition during cleaning. By modifying how and when the fragrance is applied (depositing during the cleaning process rather than after), the system achieves effective deodorization at lower doses because the fragrance is delivered directly to the substrate where it is needed
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The compound enhances fragrance substantivity and deodorization by releasing aromatic aldehydes or ketones, providing a fresh lingering fragrance and effective deodorization without disrupting skin flora or requiring high antimicrobial doses.
Implementation Method 1
