This calculator was built to help you formulate with confidence. It includes safety‑minded guardrails based on IFRA Category 9 guidelines so you can explore blends without worrying about going over typical wash‑off limits.
Every essential oil is unique, though — different suppliers, distillations, and chemistries can change what’s considered safe. Your supplier’s IFRA Certificate of Compliance is always the final word on usage rates for your specific material. Think of this tool as your planning companion, not a replacement for the IFRA documentation that comes with your oils.
