Surfacine

Inert

Surfacine remains fully inert and bio-active after exposure to a variety of physical and chemical stresses:

  • Low temperature (-15°C)
  • Ethanol and boiling water
  • Prolonged exposure to solutions of varying pH (4 - 10)
  • High ionic strength solution (2% sodium chloride)
  • Long term exposure to urine (35°C for 7 days)
  • Human serum albumin (0.7%) in phosphate buffered saline
  • Exposure to blood products
  • Worn by human volunteers for a 3 day period
  • Gamma irradiation (5 Mrad)
  • E-beam sterilization (25 kGrays)
  • Ethylene oxide sterilization
  • Autoclave (wet or dry)
  • Multiple exposure to bacterial challenge
