Frequently asked questions

What is an IFRA certificate?

An IFRA certificate is a document verifying that a fragrance mixture is safe for consumer use at a specified concentration within a particular product category, based on IFRA standards.

Do IFRA limits apply to natural essential oils?

Yes, many natural essential oils contain restricted components (such as coumarin or linalool) that are strictly regulated by IFRA to prevent dermal sensitization and phototoxicity.

What happens if the IFRA Amendment changes?

When a new IFRA Amendment is published, you must recalculate your formulas against the new restrictions and update your certificates to ensure continued compliance.

What is the difference between IFRA Category 9 and Category 12?

Category 9 covers products that are rinsed off, like bar soaps and shampoos, while Category 12 covers products not intended for direct skin contact, such as candles and air fresheners, which generally allow higher fragrance limits.
