TCP is a very, very good anti-wear/EP agent and solvent.
This is the ingredient that causes the requirement for it to be shipped ground as well and why some countries no longer allow it's use.
While the original TCP is a neurotoxin, later variation have reduced the component that have this effect.
BTW - most other VOAs show this to be in the 850-900 ppm range.
