Ingredient review
Methoxypropohexene
INCI: CIS-METHOXYPROPOXYHEXENE
A synthetic scent ingredient that adds a fresh, green note but offers no skincare benefits and may cause sensitivity in some individuals.
In plain English
This is a man-made chemical added to products to give them a pleasant, fresh, green smell. It doesn't moisturize, protect, or treat your skin—it's purely for fragrance. Because it's a fragrance ingredient, it can sometimes cause irritation or allergic reactions, especially in people with sensitive skin.

What it is
A synthetic organic compound from the hexene family, specifically designed for use as a fragrance ingredient in cosmetics and personal care products.
How it works
It works by evaporating from the skin's surface, releasing scent molecules that are detected by the olfactory system. It does not interact with the skin's biology in a meaningful way beyond potential irritation in sensitive individuals.

Low irritation risk for most
At typical low concentrations, it is unlikely to cause problems for people without fragrance sensitivities.

Usage tips
Safety summary
Generally considered safe at low concentrations for most people, but can be a skin allergen. Limited published safety data specific to this ingredient.
Research notes
There is very little peer-reviewed research on this specific compound. Safety assessments rely on general fragrance ingredient guidelines and industry data.
Common label clues
- Typical concentration
- Typically used at very low levels (under 1%) in finished products
- Regulatory status
- Approved for use in cosmetics in the EU and US, but must be listed on the ingredient label. In the EU, it is subject to fragrance allergen labeling requirements if present above certain levels.
- Common uses
- Fragranced skincare, Body lotions, Cleansers, Perfumes
- Environmental note
- As a synthetic compound, its environmental persistence and biodegradability are not well-documented. Natural fragrance alternatives may have a lower environmental footprint.
Good to know
- Fragrance ingredients are often listed simply as 'fragrance' or 'parfum' on labels, so you may not see this specific name on the bottle.
- The 'cis' in the name refers to the molecular geometry, which affects the scent profile.
