Is a bamboo toothbrush fully biodegradable?

Not entirely. The bamboo handle is 100% biodegradable and can be composted at home. However, the bristles contain PBT as one of their ingredients—a durable synthetic material that is not biodegradable. We recommend removing the bristles before composting the handle.

To be transparent, truly compostable or fully plant-based bristles that meet global oral care standards are not yet widely available at scale—either in India or globally. Based on current research and industry practices, PBT is considered a more reliable and hygienic option than conventional nylon-based bristles. Meanwhile, we are continuously exploring better end-of-life solutions for our toothbrushes as part of our ongoing commitment to improvement.
