Cooling Spray Formulation

Regarding your question about converting a cooling spray formula using Alcohol and Freeze Me (Menthone Glycerin Acetal) to use Fractionated Coconut Oil and peppermint oil for 4-5 hours of cooling, it is unlikely that this conversion will achieve the desired long-lasting cooling effect.

Here's why:

• Base: The original formula uses Alcohol (such as Ethyl Alcohol 99.9% or Ethyl Alcohol 96%) which is a volatile solvent that evaporates quickly, making it suitable for a spray and helping to deliver the cooling sensation rapidly. Fractionated Coconut Oil is an oil base, which does not evaporate quickly and is not typically used as the primary base for a fast-drying cooling spray.
• Cooling Agent: The original formula likely uses a long-lasting cooling agent like Menthone Glycerin Acetal (similar to CoCool™ which is Menthol+Menthyl Lactate, or Menthyl PCA). These ingredients are designed to release a cooling sensation over an extended period. Peppermint oil contains menthol, which provides a cooling effect, but the duration is generally much shorter compared to specialized long-lasting cooling agents.

While Fractionated Coconut Oil can be a good carrier oil for essential oils like peppermint oil, the combination in an oil base will not provide the same quick, evaporative cooling or the extended cooling duration that a formula based on alcohol and a long-lasting cooling agent can offer.

If your goal is to achieve a cooling effect that lasts for 4-5 hours, it would be more effective to continue using a formula based on Alcohol with a long-lasting cooling agent such as CoCool™ (Menthol+Menthyl Lactate) or Menthyl PCA.
