A family of compounds less versatile than those based on carbon, but useful and includes ones which seem generally fairly unreactive in biological environments.

Silicone polymers include polydimethylsiloxane (also known as dimethicone), which depending on the length and cross-linking, can range in property from a silicone oil to a more solid resin.

Silicone implants do not solve life's problems.

Also used in:

  • As an alternative to latex for flexible tubes/drains/devices, e.g.
  • Non-adhesive dressings
  • Scar reduction gel (silicone + teflon = Dermatix®)
  • Breast prostheses - external and implants
  • Other implantable prostheses, e.g. hearing aid fittings
  • Injectable material to augment anal sphincter - see PTQ.
  • Anti-foaming agent, see simethicone, sometimes used in food (E900)
  • Head lice treatment - Hedrin® is a 4% dimeticone lotion which covers and smothers the lice.
