Solution Overview
Problem
Existing fragrance compositions struggle to maintain scent retention on objects, particularly textiles, due to volatility and dispersion issues.
Innovation Solution
A fragrance composition comprising a fragrance compound (Component A) and a compound represented by Formula 1 (Component B), which forms vesicles to solubilize Component A, reducing volatility and enhancing scent retention on objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If fragrance compounds are used directly in conventional compositions, then the fragrance can be applied to objects, but the scent retention performance is poor due to volatility and dispersion issues
Solution Approach 1:
The patent introduces a specific surfactant compound (component B) as an intermediary substance that forms vesicles to encapsulate fragrance compounds (component A). This mediator enables the fragrance to be delivered to textile substrates while controlling volatility, achieving both application and sustained release. The surfactant acts as a carrier that resolves the contradiction between initial application and long-term retention.
Solution Approach 2:
The patent changes the physical state and delivery parameters of fragrance compounds by formulating them in a specific aqueous composition containing the surfactant at 0.01-5 mass%. This parameter change transforms the fragrance from a volatile substance into a stabilized vesicle-encapsulated form that can be uniformly applied and retained on textile substrates, improving both duration and reliability.
2Adaptability or versatility
If multiple fragrance materials are mixed to control scent balance, then the fragrance composition can be customized, but the formulation complexity increases
Solution Approach 1:
The patent creates a universal fragrance composition system where the specific surfactant compound (component B) serves multiple functions: it forms vesicles for encapsulation, provides aqueous solubility, enables textile treatment, and controls release. This multi-functional approach allows various fragrance compounds to be used with the same base formulation, reducing overall formulation complexity while maintaining customization capability.
3Loss of information
If fragrance is applied to textile products, then the product gains scent identification effect, but the fragrance disperses and loses intensity over time
Solution Approach 1:
The patent employs a nested structure where fragrance compounds (component A) are encapsulated within vesicles formed by the surfactant (component B). This nested arrangement protects the fragrance from premature dispersion while allowing controlled release onto textile substrates, maintaining scent intensity over time and improving compositional stability.
