Perfuming Composition Crystallization via Hexylene Glycol
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tricyclodecanedimethanol alcohol (TCD alcohol DM) in perfuming compositions tends to crystallize or gel upon storage, making it difficult to predict the shelf life of consumer products and rendering them less appealing or unusable over time, with no prior solutions addressing this issue.
Innovation Solution
Incorporating hexylene glycol as a perfumery carrier in the perfuming composition, maintaining a weight ratio with TCD alcohol DM between 0.1 to 15, which prevents crystallization and maintains the composition's transparency and viscosity, ensuring stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If tricyclodecanedimethanol alcohol is used as a viscosifying agent in perfuming composition, then the composition achieves high viscosity, but the composition crystallizes or gels upon storage
Solution Approach 1:
Hexylene glycol acts as an intermediary substance between TCD alcohol DM and the perfume oil. It mediates the interaction by forming a eutectic mixture that prevents crystallization while preserving the high viscosity property. The hexylene glycol interferes with the crystal lattice formation of TCD alcohol DM, thereby preventing gelation and maintaining composition stability.
Solution Approach 2:
The invention changes the compositional parameters by introducing hexylene glycol at specific concentrations (0.1-15 weight ratio with TCD alcohol DM). This parameter change modifies the phase behavior and crystallization kinetics of the system, transforming it from a crystallizing mixture to a stable, transparent viscous composition throughout its shelf life.
2Ease of operation
If TCD alcohol DM is heated to become transparent and fluid, then the composition becomes more usable, but recrystallization occurs upon storage reducing shelf life predictability
Solution Approach 1:
Hexylene glycol performs a preliminary protective action by preventing crystallization from the outset. Instead of requiring heating to restore fluidity, the composition remains fluid and transparent throughout storage due to the preemptive effect of hexylene glycol on crystal formation, eliminating the need for periodic heating treatments.
Solution Approach 2:
The invention converts the potentially harmful recrystallization phenomenon into a benefit by using hexylene glycol to control and delay crystal formation. The slow crystallization kinetics induced by hexylene glycol actually extend the fluid state duration, transforming the shortcoming into an extended shelf life without requiring thermal processing.
3Force
If prior art compositions with TCD alcohol DM and dipropylene glycol are used, then viscous perfumed composition is achieved, but crystallization occurs over time rendering the composition unusable
Solution Approach 1:
The invention changes the chemical composition parameter by replacing dipropylene glycol with hexylene glycol. This substitution fundamentally alters the interaction dynamics between the viscosifying agent and perfume components, preventing the crystallization pathway that occurs with dipropylene glycol while maintaining the desired viscous properties.
