Know Your Ingredients: Limonene

by Gio


What it is
Limonene is a component of many fragrant natural ingredients. For instance, it is present in citrus oils (d-limonene) and plants in the mint family (l-limonene).

What it does
D-Limonene is used in fragrances because of its strong orange-lemon odour, while l-limonene for its piney-like aroma.
In addition, limonene can enhance the penetration of other ingredients into the skin

Side effects
Limonene can cause irritations and allergies.

Does it cause allergies because it’s scented? This ingredient isn’t so hard to remember :D. LEMON or LIMON haha.

Janessa, I wouldn’t think so as all ingredients have their own odour. The reason is that limonene can break down to form small amounts of oxidation products when exposed to light and air. And when oxidized lemonene can cause allergies.

I’ve always wondered what Limonene was – sounds like a toilet cleaner!
