Citronellol

What Citronellol is & what it does

A rose-like fragrance component found in geranium and rose oils. It contributes scent and is a recognized fragrance allergen.

What is Citronellol and what does it do in sunscreen?

Citronellol is a rose-like fragrance component found naturally in geranium and rose oils. In a sunscreen it is there for scent, helping to mask the smell of the filters and base. It can be naturally derived or made synthetically, and both forms are the same molecule.

Is Citronellol safe?

For most people, yes, at the low levels used in cosmetics. The main thing to know is that it is a recognized fragrance allergen, so a minority of people can develop contact sensitivity to it. The EU requires it to be named on the label once it passes a set threshold, which is exactly why you can see it spelled out here.

Why is Citronellol listed separately on a sunscreen label?

Because it is one of the fragrance allergens that EU rules require to be declared by name when present above a set level, rather than hidden inside the word fragrance or parfum. Seeing it listed is a transparency measure, not a warning that something is wrong. It simply lets fragrance-sensitive people spot it.

Can Citronellol irritate sensitive skin?

It can for a minority of people. As a known fragrance allergen, it is one of the components most worth avoiding if you have a history of reacting to scented products or have very reactive skin. Most people tolerate it without any issue, but if you are fragrance-sensitive, a fragrance-free sunscreen is the safer choice.

Does Citronellol clog pores?

No. Citronellol is a lightweight aromatic molecule used in tiny amounts for scent, not an oil or wax that could block a pore. Its relevant concern is fragrance sensitivity, not comedogenicity. Pore-clogging, if it happens, comes from the richer emollients in a formula instead.
