How do you get the urea dissolved and processed in next preparation? Urea 5% Salicylic acid 40% Collodion elasticum AD 100 cc.

Dissolving is also impossible with the help of a cosolvent, which is miscible with collodion, because urea is only soluble in water. For me, the only solution is to omit urea. Suspending me also seems extremely difficult. If the preparation is to be used for the removal of warts, then there is the possibility to combine salicylic acid with lactic acid.
