Hexahydro-Methanoindenyl Propionate
INCI: HEXAHYDRO-METHANOINDENYL PROPIONATE
A synthetic fragrance compound that adds a pleasant woody scent but offers no skincare benefits and may cause sensitivity in some individuals.
In plain English
This is a man-made ingredient that gives products a warm, woody, or slightly sweet smell. It doesn't moisturize, treat, or protect your skin—it's purely there for fragrance.

What it is
A synthetic organic compound from the propionate ester family, specifically designed for use as a fragrance ingredient in cosmetics and personal care products.
How it works
It evaporates from the skin's surface, releasing scent molecules that interact with olfactory receptors. It does not actively interact with skin biology or provide any functional skincare benefit.

Low irritation for most
At typical low concentrations, it is generally well-tolerated by people without fragrance sensitivities.
Cons and cautions
No skincare benefit
This ingredient is purely for scent—it does not hydrate, soothe, or protect the skin in any way.

Like many synthetic fragrance ingredients, it can cause contact dermatitis or allergic reactions in sensitive individuals, especially with repeated use.
Best for
- People who enjoy scented skincare and have no history of fragrance allergies
- Those looking for a synthetic alternative to natural woody scents
