Please a tip for the preparation of: Menthol 0.5% Urea 5% locoid Cream 30g cold cream (alphapharma) 100g water 100g

Given the Doctor Locoid Cr è prescribes me and not the ointment is pushed the whole in the direction of an O/W. Now this type is probably also preferable to a W/O given the presence of urea, which will destabilize a W/O for sure. The menthol can be mixed with the cold CR è me and the urea dissolved in water. The Locoid cr è me is then mixed with the cooling ointment and then this mixture with the urea solution is diluted. Should the whole break down then a minimum amount of Tween 80 can be added.
