Standing there in my bathroom this morning, shaving and wondering about various things, I noticed some small text on the back of the deodorant bottle. I usually don’t read it, like pretty much 99% of the people in the world I suspect.

It said this though: no CFCs contained in this product.

That’s been around for a while now, but it did make me wonder about something else. Two questions really:

  • Why do we need this on products after this long? Surely we all know that CFCs are not in anything these days.
  • More (vastly) importantly: what replaced CFCs, and will they be the next CFC?
