These are best for refreshing the skin and giving emotional balance. They help fight infections and boost the immune system. Lavender, peppermint, and clary sage are high in monoterpenoids. They have considerable molecular weight and enhance chemical stability. Monoterpenoid’s shelf life lasts three to five years.

Which Factors Involved Changes In Essential oils

Heat exposure can be minimized by keeping oil bottles in a cool place—the perfect temperature for essential oil is b/w 35 to 38 degrees.


Dark-colored bottles are the best way to reduce light exposure. Light can promote oxygen-free radicals. In addition, light is very responsive and could change the essential oil.
