Known Allergens in Essential Oils: What They Really Mean

If you’ve ever looked at an ingredient list and seen names like Limonene, Linalool, Farnesol, Citral, or Geraniol, you might have wondered what they’re doing there. At Fyrn™, we believe in keeping things transparent, so let’s clear it up.

What They Are

These aren’t synthetic additives. They’re naturally occurring compounds found in essential oils. For example:

• Linalool comes from lavender and tea tree
• Limonene is abundant in citrus oils and peppermint
• Farnesol appears in chamomile
• Citral and Geraniol are part of lemongrass and geranium

Why They’re on Labels

In the European Union, these natural fragrance components must be listed if they’re present above very small levels. This helps people with sensitivities or allergies know what’s inside. While U.S. regulations don’t require this, we choose to include them anyway. It keeps our products future-ready and shows our commitment to honesty.

What It Means for You

When you see these names on a label, it doesn’t mean extra chemicals were added. It simply means we’ve declared what naturally exists in the essential oils we use. It’s part of our promise to keep every product safe, clear, and true to nature.

The Fyrn™ Standard

On our labels, you’ll find a line that says:

Naturally occurring in essential oils: Limonene, Linalool, Citral, Farnesol, Geraniol.

This way you know exactly where these compounds come from and why they appear. It’s just another way we’re building trust through transparency, while staying rooted in clean, plant-based care.

Sensitive to Essential Oils?

We know that some people prefer to avoid fragrance allergens altogether. That’s why we created Fyrn™ Pure, our unscented collection. These formulas deliver the same plant-based care without added essential oils, making them a great choice for sensitive skin or anyone looking for a fragrance-free option.
