yep, I keep it in a polyethylene squeeze bottle (HF bottle) with the red cap, and it doesn't leak out.. I am not sure why it doesn't. The cap is not real tight, but it doesn't evaporate that I notice.Acetone has a high vapor pressure, so it can leak out of loose openings, and enough surface tension to wick through capillaries. But it doesn't pass through the polymer bottle. They sell acetone in quart and gallon jugs made of PP plastic all over the world, including my local Lowe's. I guess you could say that light solvents are like sea lions. They like a tight seal.
