Surfactants

  1. 1. Surfactants Nathan Westbrook
  2. 2. surf(ace)-act(ive) a(ge)nt surface-active agent, a substance, such as a detergent, that can reduce the surface tension of a liquid and thus allow it to foam or penetrate solids; a wetting agent D efinition:
  3. 3. Surface Tension Surface tension of liquids makes it difficult to penetrate and mix with other chemicals. Surfactants are used to help the chemicals work with each other. For instance, the in a laundry detergent, the surfactant helps the water release the oils in the clothing. The water becomes “wetter.”
  4. 4. It is interesting to understand how surfactants are really used in every day life by so many and is hardly understood by the majority of people who depend on them in their daily use.
  5. 5. What is an example of a surfactant in embalming? Water/Clot Guard from Frigid© is added to the water to condition it and aid in penetration of the embalming chemicals.
  6. 6. Why is it important? Understanding the way water molecules interact with other chemicals and the capillaries in the body helps the embalmer reach the best penetration of all surfaces of the body.
  7. 7. What more should we think about? Knowing when and when not to use surfactants in an embalming solution is something that seems to come with time. From my understanding, it is almost always a good idea to use some type of surfactant or water conditioner. But not every does use it. What are your questions?
