Question
Posted on: March 6 2013Composition: Menthol 0.75 g salicylic acid 4.5 g Betamethasone. val 150mg Lanettecème 45g Vaseline AD 150g
When we mix the petroleum jelly with the LANETTECR è me we get A & #039; cabled & #039; result and no even CR è me, probably because too much petroleum jelly is added to the CR è me. How can we improve this?
Answer
This is a composition with a contradiction. Either one seeks O/W cr è me and then 45g Lanettecr è me can not absorb 100g vaseline; Either one seeks a W/O creme and then one replaces the LANETTECR è me by a certain amount of water and Arlacel C as usual in the AVA cr è me. The ball is in the doctor's camp!
