What is that pink-ish, goopy, clear coat they apply on top of a manicure?

I know it's a top coat, but what specifically because all the top coats I've looked for are just clear, not with a pink tint like the ones in the salons.What is that pink-ish, goopy, clear coat they apply on top of a manicure?
