Question
Posted on: April 23 2018Preparation with 4g salicylic acid, 3g sulpho resorcinol, castor oil 1drop, in 10g Vaseline
Due to the high amount of powder in a small amount of ointment, this becomes hard. Should something be adjusted?
Answer
Maybe you will get a fat paste when you replace all the petroleum jelly by castor oil. If not then you can increase the consistency by adding aerosil.
