The Humble Co. Humble Brush Bamboo Toothbrush
A pharmacy-shelf bamboo brush marketed as biodegradable, whose "65% plant-based" bristles are still 100% nylon in your mouth.
The verdict: Significant plastic contact
The handle composts; the bristles don't. Humble's bamboo toothbrush is marketed as biodegradable and compostable, but the bristles - the contact surface - are BPA-free nylon described as roughly 65% castor/plant-based. A "65% plant-based" nylon is still 100% nylon: it does not compost and it sheds microplastic. The bamboo handle is real and biodegradable, which is exactly what makes the "biodegradable" framing misleading - it quietly describes the handle, not the bristles that matter.
What it's made of
| Part | Material | Skin contact |
|---|---|---|
| bristles BPA-free nylon, ~65% castor/plant-based - still 100% nylon | Nylon Polyamide | Yes primary |
| handle bamboo handle | Bamboo | No |
A standard adult bamboo toothbrush sold widely in pharmacies and supermarkets. It brushes normally and the handle is genuine bamboo; it is documented rather than recommended because of the nylon bristles. Worth noting as neutral context: the same brand's bamboo cotton swabs are a genuine plastic-free pick (a bamboo stick with a cotton tip) - so this is a brand that lands on both sides of our line depending on the product, and it's the bristles that put this one on the wrong side.
Pros
- Handle genuinely is bamboo, not plastic
- Cheap and very widely available
Cons
- Bristles are nylon despite "plant-based / biodegradable" marketing
- Not compostable as sold; the bristles must be removed first
- The "biodegradable" framing describes the handle, not the contact surface
