In personal care

A naturally occurring aldehyde with a strong lemon scent, found in lemongrass and citrus oils, and also produced synthetically for fragrance use.

Why it’s used

It supplies a bright citrus note in perfumed cosmetics, cleansers, and household products.

What the evidence says

Citral is recognized by EU regulators as a fragrance allergen capable of causing contact sensitization in a subset of users, based on patch-test and clinical data reviewed by the Scientific Committee on Consumer Safety.

Context

EU rules require it to be listed by name on labels when present above 0.001% in leave-on products and 0.01% in rinse-off products, reflecting that reaction risk depends on concentration and contact type.
