How to Interpret the Risk Ratings in This Tool

We use a three-tier risk system to help guide safer formulation decisions:

• ✅ Low Risk – No significant IFRA restrictions. Generally considered safe under standard usage and dilution conditions.

• ⚠️ Moderate Risk – No specific IFRA percentage limit, but the material contains known allergens (e.g., Linalool, Citral, Geraniol) that require label disclosure under EU regulations. Also includes materials prone to oxidation or skin sensitisation when degraded.

• ⚠️ High Risk – These materials have a specific IFRA usage restriction (e.g., Cinnamon Bark, Clove, Tagetes) or contain constituents (like Methyl Eugenol, Safrole, or Cinnamaldehyde) that are regulated at very low maximums.

This tool is especially useful for natural perfumers who want to work within IFRA and EU safety standards, particularly for products intended for market.
