Handheld Raman Spectroscopy for the Distinction of Essential Oils Used in the Cosmetics Industry.

Essential oils are highly appreciated by the cosmetics industry because they have antimicrobial and antioxidant properties, among others. Since essential oils are natural products, their inclusion in cosmetic formulations is a common practice. Currently, low-quality and/or adulterated essential oils...
