Where plastic hides in dental floss

Conventional floss is nylon or PTFE, and the "natural" versions often swap one plastic for another with a better label. "Corn-based" floss is PLA, and "plant-based" often is too. "Biodegradable nylon 1010" is nylon made from castor oil. Silk floss waxed with candelilla or beeswax has no plastic in the thread. Then check the dispenser: the cutter blade is steel or plastic, a glass jar's steel lid may have a gasket behind it, and refills ship in a pouch.

What to check before you buy

  1. The thread: silk or another plant fiber, or nylon, PTFE or PLA?
  2. The wax: candelilla or beeswax, or an unnamed or synthetic wax?
  3. The dispenser: glass and steel, or plastic?
  4. The cutter: steel, or plastic?
  5. The gasket in the lid: none, cork or natural rubber, or silicone?
  6. Refills: paper, or a plastic or "cornstarch" pouch?
