Question
I am planning to use the ingredient `Menthol Water Soluble (20% Menthol, Liquid)` (ID 7473) in a cosmetic formula.
1. Is this ingredient suitable for use in facial products?
2. What is the recommended usage percentage for this ingredient in cosmetic formulas?
Answer
The product Menthol Water Soluble (20% Menthol, Liquid) (ID 7473) can technically be used in facial products, but extreme caution is advised.
1. Can it be used on the face?
Menthol provides a strong cooling sensation which can be irritating, especially on sensitive facial skin, around the eyes, and on mucous membranes.
- Caution: If you choose to use it on the face, you must start with a very low concentration and strictly avoid the eye area.
- Recommendation: This ingredient is generally better suited for body products (e.g., foot creams, body washes, muscle rubs) where a strong cooling effect is desired and the skin is less sensitive.
2. Recommended Percentage in Cosmetic Formulas
The recommended usage rate for Menthol Water Soluble (20% Menthol, Liquid) in cosmetic formulas is:
- General Use: 0.1% to 5%
- For Facial Use: If used on the face, it is highly recommended to use a concentration at the lower end of the range, such as 0.1% to 0.5%, to minimize the risk of irritation and burning sensation. You should always test the final product on a small area of skin before full application.
