8-Methoxy-2,6-Dimethyloct-2-ene
INCI: 8-METHOXY-2,6-DIMETHYLOCT-2-ENE
A synthetic fragrance ingredient that adds a fresh scent but offers no skincare benefits and may irritate sensitive skin.
In plain English
This is a man-made chemical added to products to give them a pleasant, fresh smell, often like citrus or green notes. It doesn't moisturize, protect, or treat your skin—it's purely for scent. Because it's a fragrance ingredient, it can sometimes cause irritation or allergic reactions, especially if you have sensitive skin or a history of fragrance allergies.

What it is
A synthetic organic compound from the terpene family, created in a lab to mimic natural scents. It is used exclusively as a fragrance ingredient in cosmetics and personal care products.
How it works
It evaporates from the skin's surface, releasing molecules that interact with olfactory receptors in the nose to produce a fresh, pleasant scent. It has no known active effect on skin biology or appearance.
