Answer
In the literature it is described that for the dissolution of Salicylic acid in shampoo & #039; s is best used of Cetomacrogol 1000. As a large amount of salicylic acid occurs here, minimum 25g Cetomacrogol 1000 will be required. This is melted and the liquid is first added salicylic acid and then the LCD. If the shampoo is not clear, the amount of cetomacrogol will need to be increased.
