Is Limonene Safe in Makeup?

Yes, limonene is generally safe in makeup, but it can cause allergic reactions in sensitive individuals.

Limonene is a naturally occurring compound found in citrus fruits that's commonly used in cosmetics as a fragrance and solvent. While it's considered safe for most people, the EU requires it to be listed separately on ingredient labels when present above 0.001% in leave-on products because it's a known allergen.

The ingredient has an EU restriction classification (III/88), meaning its use is regulated to ensure consumer safety. Studies show that while limonene itself isn't highly sensitizing, it can oxidize when exposed to air, forming compounds that are more likely to trigger allergic reactions.

Who should avoid it: People with known citrus allergies or those who experience skin irritation from fragranced products should patch test first or avoid products containing limonene entirely.
