The natural ingredients in Quell

Quell’s carton lists Natural Ingredients among its front-panel claims, and the About page names them: emu oil, manuka honey, Dead Sea salt and Terminalia chebula sit alongside the lubricants in the inactive ingredient list.

Where they appear

All four are inactive ingredients. The actives, which give the drop its lubricating purpose, are Glycerol (1.0%), Polysorbate 80 (1.0%) and Light Mineral Oil (0.5%). The full inactive list reads: Caprylyl Glycol, Dead Sea Salt (Sodium Chloride), Emu Oil, Glyceryl Laurate, Glyceryl Undecylenate, Manuka Honey, Polaxamer 188, Sterile Water, Terminalia Chubula and Tromethamine.

What the formula is designed to do

Rich in bioactive fatty acids and botanical antioxidants, the formula supports a more stable tear film. These natural compounds are known for their calming and soothing properties.

Natural isn’t the same as suitable for everyone

Emu oil is the reason for the label’s caution: Caution should be used in those with egg or bird allergies — For use in the eyes only. If you have other allergies, check the full list with a doctor or pharmacist before ordering.

The color

These ingredients account for much of the drop’s milky brown color. Why Quell is milky brown explains.
