What Citronellol does

Gives products a fresh, rose-like scent
Blends with other fragrance notes
Helps cover up other odors

Citronellol occurs naturally in plant oils such as rose, geranium, and citronella. Many products use a version made in a lab, which keeps its scent steady from one batch to the next.

Formulators use citronellol to add a fresh, floral, slightly green scent. It blends well with other fragrance notes, so it often sits inside a larger scent blend. It is common in shampoos, conditioners, body washes, and lotions, where a light smell is expected. It is valued for scent, not for hydration.

Frequently asked questions

Is citronellol safe for sensitive skin?

Most people tolerate citronellol well, but it is a labelled fragrance allergen, so some people react to it. If your skin is sensitive, check the ingredient list and try a patch test on a small area before using a new product.

Does citronellol moisturize skin?

No. Citronellol is used for its scent, not for hydration. Moisture comes from other ingredients in the formula, such as emollients, which soften, and humectants, which draw in water. Citronellol may make a lotion smell pleasant, but it does not replace those ingredients.
