Oath cares about you. To show we care and to keep you safe, we make sure all our products and manufacturers are certified. We believe in being transparent. That’s why all our certifications, and our manufacturer’s certifications, are available to you. 

There is a risk in doing this. Our competition can easily see where we get our products manufactured and could potentially copy us by using the same supplier. We decided it was worth the risk to prove to you that we mean what we say and can back it up. No empty promises or hidden agendas.

We are one of the ONLY sustainable, zero-waste retailers that give out this information. Keep that in mind the next time you are looking to purchase a zero-waste alternative. 

USDA Bio-Based Certification

“The increased development, purchase, and use of biobased products reduces our nation's reliance on petroleum, increases the use of renewable agricultural resources, and contributes to reducing adverse environmental and health impacts.”
 - BioPrefferred Website

Our bamboo toothbrush handle is certified 99% Bio-Based. In the future, we hope to certify our silk floss as 99% Bio-Based. Please visit the USDA BioPreffered website for more information.

Leaping Bunny

“Cruelty Free International works to end animal experiments worldwide. We do this by investigating and exposing the reality of life for animals in laboratories. We challenge decision-makers to make a positive difference for animals. And we champion better science and cruelty free living.”
 - Leaping Bunny Website

Oath loves all animals! That’s why we need to have all our products certified Cruelty Free by the leading certification agency, Leaping Bunny. We worked with our manufacturers to verify they never test on animals.

Why are some parts blurred out?

Our manufacturers would like to keep some proprietary business information confidential. There’s a lot of competition in this industry and we respect their request for confidentiality.

Why are some test reports not recent?

We obtained the most recent reports available from our suppliers. We want to start doing third party testing to verify our supplier’s test results. Unfortunately, due to the high cost, we are not able to re-test everything at this time.
