Liquid Cooling Compound Formulation in Lactic Acid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-natural cooling compounds are often crystalline solids, making them difficult to mix into liquid consumer products and posing dust hazards, while also potentially contributing to the flavor or fragrance profile undesirably.
Innovation Solution
A liquid composition comprising at least one non-natural cooling compound dissolved in lactic acid, which allows for higher solubility and stability, minimizing the contribution to the flavor or fragrance and avoiding solid handling issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If non-natural cooling compounds are used in crystalline solid form, then cooling potency is achieved, but mixing difficulty and dust hazards increase
Solution Approach 1:
The patent changes the physical state parameter of the cooling compound from solid to liquid by dissolving it in lactic acid. This transformation maintains the cooling potency while eliminating the handling difficulties associated with crystalline solids, including mixing inconvenience and dust hazards.
Solution Approach 2:
Lactic acid serves as an intermediary solvent that facilitates the delivery of cooling compounds. It enables the cooling compound to be in liquid form, improving ease of operation while maintaining the cooling effect through the solvent-mediated delivery system.
2Reliability
If non-natural cooling compounds are used in crystalline solid form, then cooling potency is achieved, but handling safety deteriorates due to dust hazards
Solution Approach 1:
By changing the physical state from solid to liquid through dissolution in lactic acid, the patent eliminates dust formation entirely. The liquid formulation cannot generate dust hazards while preserving the cooling compound's potency and effectiveness.
3Quantity of substance
If ethyl lactate is used as solvent for cooling compounds, then solubility is improved, but flavor contribution increases undesirably
Solution Approach 1:
The patent uses lactic acid, which is structurally related to ethyl lactate (both contain the lactate functional group), but replaces it with a version that does not contribute unwanted flavors. This substitution maintains the solubility benefits while eliminating the harmful flavor effect.
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 liquid composition achieves high solubility of non-natural cooling compounds in lactic acid, resulting in a stable and easy-to-use form that does not significantly impact the flavor or fragrance of formulations, while reducing handling risks.
