Cooling Agents for Water-Based Scalp Spray

For a water-based spray for the scalp that provides a cooling sensation, the following cooling agents are recommended:

• Water-Cool™ (Water-Soluble Cooling Agent): This ingredient is specifically designed to be water-soluble and can be directly mixed into clear, water-based spray formulas. It provides a cooling effect that can last for over an hour.
• WS-10 Cooling Agent (Menthoxypropanediol): This is a liquid cooling agent known for its high cooling efficiency, reported to be approximately 4.5 times stronger than menthol. It is soluble in glycols, oil, or ethyl alcohol, and could potentially be incorporated depending on the overall formulation.

Choose the ingredient that best suits your desired cooling intensity and formulation requirements.
