big bottle of acetone based nail polish remover [SEP] like other nail polish removers this mountain falls regular nail polish remover for natural nails with vitamin e and panthenol fluid ounce is mostly acetone it smells like all the other nail polish removers that i ve tried and works like them tooi use nail polish remover to take gummy stuff off my hands and other things if you use it this way it s important to remember that it can damage synthetic fabrics wood finishes and plastic also when using or storing it remember that it s highly flammable and should not be used or stored near fire flames or heat see my photo of the bottle label with all the warnings the big oz bottle is equivalent to two of the regular size bottles for example that you find at local grocery and drug stores
