Adding a Cooling Sensation to Your Shampoo Formula

To give your shampoo formula a cooling effect, you can incorporate cooling agents. These ingredients provide a refreshing sensation on the scalp.

Common cooling agents suitable for cleansing products like shampoo include:

• Menthol: Provides a strong and immediate cooling sensation. However, the cooling effect might not last as long, and it can sometimes cause a tingling or irritating feeling at higher concentrations.
• Menthyl Lactate: A derivative of menthol that offers a milder cooling sensation. The cooling effect develops gradually and tends to last longer than menthol. It is generally less irritating than direct menthol.

You can use either of these ingredients or a combination. Start with a low concentration (e.g., 0.1-0.5%) and adjust based on the desired level of coolness.

A relevant product available is Laevo-menthyl lactate (FEMA-3748), which can be used to impart this cooling sensation.
