Cooling Spray Formulation

Based on the product descriptions:

1. Water Base for Cooling Spray: You can create a cooling spray with a water base, but incorporating 10% "Freeze Me" (Menthone Glycerin Acetal) will be challenging. The product description for "Freeze Me" states that it is soluble in water only up to 0.12%. To dissolve a higher concentration like 10% and keep it stable in a water-dominant formula, you will need a significant amount of a co-solvent, such as ethanol or glycol (like Propylene Glycol or Butylene Glycol).

2. Amount of Ethanol Needed: The product description does not provide a specific ratio for dissolving 10% "Freeze Me" in a water/ethanol mix. However, given its very low solubility in water (0.12%), dissolving 10% will require a substantial amount of ethanol or another suitable solvent to prevent the "Freeze Me" from separating or precipitating over time. It's not possible to give an exact percentage without laboratory testing, but it will likely be much more than just a small amount and could result in a formula that is not primarily water-based, potentially causing dryness similar to an alcohol-based spray. If minimizing alcohol is a priority, you might consider using a lower concentration of "Freeze Me" or exploring other water-soluble cooling agents. Alternatively, using a glycol like Propylene Glycol or Butylene Glycol as a co-solvent might be less drying than ethanol.

   Regarding the other ingredient in your proposed formula:

   • Phenoxyethanol SA (1%): The description for Phenoxyethanol SA states it can be dissolved in water up to 1.0%. So, 1% Phenoxyethanol SA can be dissolved in the water phase of your formula.

3. Availability of Ethanol: Yes, Ethyl Alcohol is still available. The search results show "Ethyl Alcohol (99.9% , 200 Proof)" and "Ethyl Alcohol (96% , Perfumer Grade)" are available.

In summary, while a water base is possible, achieving a stable solution with 10% "Freeze Me" will require a considerable amount of co-solvent, likely ethanol or glycol. The exact amount of ethanol needed for 10% "Freeze Me" in your specific formula would require testing.
