A bamboo toothbrush is an eco-friendly alternative to the typical plastic toothbrush. The bamboo handle is 100% compostable and the bristles are bio-based Nylon 1010 produced from castor oil, NOT petroleum-based, like other nylon bristles out there. Biobased bristles are made from castor oil but not compostable/biodegradable. Although these bristles will eventually return to the soil, you may recycle them at your local recycling facility or with Terracyle®. Bamboo toothbrushes with horsehair or pig hair are 100% compostable but there's no way to guarantee a cruelty-free process so we only offer bamboo toothbrushes with bio-based castor oil bristles right now.
