Salicylic acid 17, 5g acetone 5g collodion with castor oil AD 50ml The salicylic acid dissolves very hard, only after heating, but after cooling off a thick mash
Answer
I would add 10 ml of denatured alcohol. Perhaps better stay overnight in small closed jar on magnetic stirrer because when heating evaporates acetone and alcohol.
