Question

When Tecnu contacts the poison oak oil or resin, does it break it down, chemically, into inert substances, or does it simply loosen its grip on the skin so that it can be washed away. Similarly, if I wash contaminated skin with Tecnu and rinse it off in a certain place in my yard, will that spot in my yard be a hazard for "reinfection" with the oil or resin?

Answer

Tecnu breaks the bond that the poisonous oil makes with the proteins in our skin, it does not break it down, chemically into inert substances. It may be possible that some of the oil residue could reside where you rinse off, but we have never tested that theory. We have never heard of anyone becoming re-contaminated from such exposure.
