Ingredient review
Trimethyl Methylenecyclohexanepropanol
INCI: Trimethyl-6-methylenecyclohexanepropanol
A synthetic scent ingredient that adds a woody or floral note; generally considered safe at low levels but offers no skincare benefit.
In plain English
This is a lab-made chemical that gives products a pleasant woody or floral smell. It doesn't moisturize, treat, or improve your skin—it's purely for fragrance. In small amounts, it's unlikely to cause problems, but if you have sensitive skin or prefer fragrance-free products, you might want to avoid it.

What it is
A synthetic organic compound used as a fragrance ingredient in cosmetics and personal care products. It belongs to a family of terpene-like chemicals that mimic natural scents.
How it works
It evaporates from the skin after application, releasing scent molecules that your nose detects. It has no active effect on the skin's structure or function.
Pros
Pleasant scent
Adds a natural-smelling woody or floral note that many people find appealing.
Low irritation risk for most
At typical low concentrations, it's unlikely to cause problems for people without fragrance sensitivities.
Cons and cautions
No skincare benefit
This ingredient only adds scent—it doesn't hydrate, protect, or improve your skin in any way.
Potential allergen
Like many fragrance ingredients, it can cause contact dermatitis or allergic reactions in some individuals, especially with repeated use.
Best for
- People who enjoy scented skincare and have no history of fragrance allergies
- Those looking for a subtle woody or floral note in their routine
