No, you can't buy it at the pharmacy, Richard.
It's a specially formulated, light, anhydrous (mineral)oil.

Mineral oil is indeed sold at pharmacies for human consumption. Light and
anhydrous, just like the lubricant for R-12.

There's nothing "specially formulated" about mineral oil for A/C. Unless

Double extra virgin mineral oil anyone?
