Now this never really bothered me in the past but on hindsight I stick this thing in my mouth just like food so it would be good to know what its composed of. What really got me though is seeing toothbrushes that say whitening or antimicrobial which begs the question. Why is this whitening or antimicrobial? What the heck is in it that is doing this action??? Now that I think of it this might be more than mildly infuriating.

    I’m very much not worried about my toothbrushes, but if you want, looks like you can get premium toothbrushes where the stuff it’s made out of is a selling point.

    One example, first hit that comes up:

    https://www.brushwithbamboo.com/shop/bamboo-toothbrush-adult/

    • Standard soft bristles made from 100% Castor Bean Oil. USDA Certified 100% Biobased. Bristles made in the European Union.
    • FSC® certified bamboo handle.
    • The box encasing the toothbrush is made from paper – no tape or glue is used.
    • Your bamboo toothbrushes can be used for just as long as plastic toothbrushes.
    • USDA Certified Biobased. Green American Certified. Vegan. BPA-Free. Natural and Non-toxic.

    That being said, I recall that re: “100% Castor Bean Oil”, ricin is made from castor beans, and that’s probably one of the most-lethal substances you could reasonably get ahold of and put inside yourself. :-)

    Ricin (/ˈraɪsɪn/ RY-sin) is a lectin (a carbohydrate-binding protein) and a highly potent toxin produced in the seeds of the castor oil plant, Ricinus communis.

      I remember in Moscow during the Soviet Union dsys my dad was amazed when he saw that stores were still selling horse hair tooth brushes.

      I wonder if they are still being made somewhere.
