Spore-Based Pro-Perfume Composition for Sustained Surface Freshness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fragrance delivery systems fail to provide long-lasting malodor removal and perfume release on surfaces, as many odorants are too volatile and existing pro-perfume activation methods face stability issues.
Innovation Solution
A composition comprising Bacillus spores, a pro-perfume material, and a perfume, where the pro-perfume material includes glycosides, phosphate acid esters, or amino-acid derivatives, which are activated by bacterial enzymes to release fragrance upon germination, providing sustained freshness on surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If conventional fragrance delivery systems are used, then fragrance can be released initially, but the fragrance becomes too volatile and is not perceived more than a few hours after application
Solution Approach 1:
The patent applies preliminary action by incorporating fragrance precursors (pro-perfumes) into the composition before application. These precursors are converted into active fragrance compounds by microbial metabolism after application, ensuring sustained release over time rather than immediate volatilization. The precursors are prepared in advance but only activated when needed, extending the fragrance duration from hours to days or weeks.
2Duration of action of moving object
If pro-perfume materials are used to extend fragrance duration, then long-lasting scent is achieved, but in-product stability is compromised
Solution Approach 1:
The patent uses microbial cells as intermediaries to bridge the stable pro-perfume materials and the active fragrance release. The microbes remain dormant during storage, maintaining product stability, but become metabolically active after application, converting the stable precursors into volatile fragrance compounds. This intermediary system resolves the contradiction by decoupling storage stability from release activity.
3Object-affected harmful factors
If existing fragrance delivery systems are used, then initial fragrance release occurs, but sustained malodor removal and long-lasting freshness are not achieved
Solution Approach 1:
The patent implements self-service by incorporating living microbial cells that continuously metabolize malodor compounds and generate fragrance over time. Rather than relying on pre-formed fragrance that simply evaporates, the system uses self-sustaining biological activity to continuously remove malodors and replenish fragrance, achieving sustained effectiveness without external intervention.
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 composition achieves sustained malodor removal and perfume release for at least 24 hours, ensuring long-lasting freshness on fabrics and hard surfaces by using Bacillus spores that germinate under specific environmental conditions.
Implementation Method 1
The pro-perfume material comprises a component capable of releasing a fragrant alcohol after hydrolysis
Implementation Method 2
activated by bacterial enzymes to release fragrance upon germination
Implementation Method 3
Bacillus spores that germinate under specific environmental conditions
