Biobased & Organic

USDA Certified 100% Biobased Bristles

Our toothbrush bristles are 100% Castor Bean Oil and USDA Certified 100% Biobased – see the USDA Certification and Testing Paperwork below. This means that our bristles contain 0% fossil fuel. Our bristles are made in Germany. For further information regarding the decomposition process of these bristles, please read our FAQ page.


Sourcing Organic Bamboo for Toothbrushes

Brush with Bamboo purchases the organic bamboo used for our toothbrushes through an exclusive agreement with a bamboo factory where we have certified the bamboo as 100% organic. See the certificate here. NOTE: due to COVID-19, our regular annual inspection to renew our organic certification has been delayed. Due to factory closures and regional closures, inspectors were not able to inspect our wild bamboo on time. We are in the process of completing our annual inspection and will post our renewed organic certificate shortly. Thank you for understanding.

Before carving, the bamboo is boiled in water and dried in a heated oven (the oven is powered by waste from the bamboo carving process – a sustainable cycle). The entire process is chemical-free and natural.

Bamboo is biodegradable, naturally antibacterial, and one of the most sustainable resources on Earth. This variety of giant Moso bamboo is panda safe – it is not food or habitat for pandas.
