Making Essential Oils Accessible & Safe

If you have ever been frustrated by the lack of proper information and safe usage guidelines on the web, you have found a safe haven among the nonsense online!

This essential oil calculator exists to bring safe essential oil usage to the masses and help formulators explore natural fragrances through blending.

If you aren’t sure what essential oils to blend together, take a peek at the essential oil blend library to find hundreds of blends submitted by the Soapmaking Community.

If you aren’t sure how much of an essential oil you should use, use the blend rate calculator to find safe usage rates based on the IFRA standards and published scientific data.

If you need help, check out the frequently asked questions to find your answers, or hit up the updates section to find more information.

About the EO Calculator

The Essential Oil Blending Calculator was originally made possible by Modern Soapmaking’s crowdfunding campaign on Indiegogo, and was created by Kenna Cote & the Modern Soapmaking team.

A huge thanks goes out to all the suppliers & members of the soapmaking community whom have helped make this site a success.

As of Summer 2021, Essentially Speaking, LLC has taken over daily operations and maintenance of EO Calculator!  We look forward to growing and expanding this site to better meet the needs of the community.
