Ingredient review
Dodecanenitrile
INCI: DODECANENITRILE
Dodecanenitrile is a synthetic fragrance ingredient that adds a fresh, citrusy scent, but it offers no skincare benefits and may cause sensitivity in some individuals.
In plain English
Dodecanenitrile is a man-made chemical used in cosmetics and perfumes to create a fresh, citrus-like smell. It doesn't moisturize, treat, or improve your skin in any way—it's purely there for scent. While generally considered safe at low levels, it can be a potential irritant for those with very sensitive skin or fragrance allergies.

What it is
Dodecanenitrile is a synthetic organic compound from the nitrile family, used as a fragrance ingredient in cosmetics. It is produced in a lab and is not derived from natural sources.
How it works
In a cosmetic product, dodecanenitrile contributes to the overall fragrance profile, typically adding a fresh, citrusy note. It does not interact with the skin's biology; its role is purely olfactory.
Pros
Pleasant scent
Adds a fresh, citrusy aroma that can make the product more enjoyable to use.
Low risk for most
At typical low concentrations, it is considered safe and non-irritating for the majority of users.
Cons and cautions
No skin benefit
Dodecanenitrile is purely a fragrance ingredient—it does not hydrate, soothe, or improve skin health in any way.
Potential allergen
Like many fragrance ingredients, it can cause allergic reactions or irritation in people with sensitive skin or fragrance sensitivities.
Best for
- Anyone who enjoys lightly scented skincare and does not have fragrance sensitivities
- People using products where a fresh scent is desired
Use caution if
- Individuals with known fragrance allergies or very sensitive skin

Usage tips
Safety summary
Dodecanenitrile is considered safe for use in cosmetics at low concentrations by major regulatory bodies. However, as a fragrance ingredient, it carries a small risk of skin irritation or allergic reaction in sensitive individuals.
Research notes
Research on dodecanenitrile is limited, but it is included in fragrance safety assessments by organizations like IFRA and the Research Institute for Fragrance Materials (RIFM), which support its safe use at low levels.
Common label clues
- Typical concentration
- Typically used at very low levels, often below 1% in leave-on products.
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions, subject to concentration limits set by fragrance safety standards (e.g., IFRA).
- Common uses
- Fragranced skincare, Perfumes, Body lotions, Cleansers
- Environmental note
- As a synthetic compound, its environmental persistence and bioaccumulation potential are not well-documented, but it is used in very small amounts.
Good to know
- Dodecanenitrile is often listed simply as 'fragrance' or 'parfum' on ingredient labels, so it may not appear by name.
- Regulatory bodies like the International Fragrance Association (IFRA) set safety standards for its use in cosmetics.
