I am looking for a SAFE substance that is either:
Soluble in mineral oil but will extract into water.
-or-
Soluble in water but will extract into mineral oil.
Safe = Non-toxic, Non-Carcinogenic, Low Reactivity.
Ideally this substance should exhibit a color in one phase or the other.
This would be used as a student experiment for a Unit Operations Lab. The old extraction experiment used a known carcinogen and was discontinued.
Thanks in advance.

You're basically asking for something that is soluble in water and mineral oil, which is a fail.
Do the liquid CO2 extraction of d-limonene from orange peels. Google it.

Not exactly what you were asking for, but I think this would be perfect for what you want to demonstrate.
The chemical, N,N-Dimethyl-4-nitrosoaniline can be bought cheaply from Sigma ($43.40 for 25g)
