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!
