Compacted Perfume Composition Using Cyclodextrin Complexation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing perfume compositions for compacted products face challenges in delivering consistent odor performance due to reduced dosage, leading to insufficient odour impact and substantivity compared to conventional perfumes.
Innovation Solution
A compacted perfume composition is developed using a 'bottom-up' creation process, comprising sub-compositions A and B. Sub-composition A includes Performance Markers and Performance Vehicles, while sub-composition B consists of Performing Diluents, all carefully selected and concentrated to achieve desired performance and hedonic qualities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If perfume concentration is reduced in compacted products, then dosage is lowered and environmental sustainability is improved, but odour impact and substantivity become insufficient
Solution Approach 1:
The patent changes the chemical composition parameters of the perfume by introducing specific solubilizing agents (cyclodextrins, polyethylene glycols, fatty acid esters) and structuring agents that enable stable perfume delivery at reduced concentrations. This allows maintaining odour performance reliability while reducing the quantity of perfume substance needed in compacted products
Solution Approach 2:
The invention creates a composite perfume composition system combining multiple functional components: solubilizing agents (cyclodextrins, PEGs, fatty acid esters), structuring agents, and perfume principles. This composite approach enables the reduced perfume dosage to deliver consistent odour performance by optimizing the interaction between these components in the compacted product matrix
2Reliability
If perfume concentration is increased to maintain odour impact, then odour performance is improved, but product stability deteriorates due to gelation and phase separation
Solution Approach 1:
The patent introduces solubilizing agents (cyclodextrins, polyethylene glycols, fatty acid esters) as intermediary substances that mediate between the perfume ingredients and the compacted product matrix. These intermediaries prevent direct harmful interactions between concentrated perfume components and the product base, thereby maintaining product stability while enabling sufficient odour impact through optimized perfume delivery
3Reliability
If perfume loading is increased in dilute systems, then odour intensity is improved, but thermal stability window is narrowed and cloudiness occurs
Solution Approach 1:
The patent replaces reliance on physical mixing and solubility equilibrium with chemical complexation mechanisms. Cyclodextrins form inclusion complexes with perfume molecules, while polyethylene glycols and fatty acid esters provide solubilization through specific molecular interactions. This chemical mechanism substitution enables stable perfume delivery at lower concentrations without cloudiness or thermal instability
