Best method to prepare this? Miglyol 200ml Eumulgin B1 50g Comperlan COD 50ml Cetiol V 50ml soybean oil 150ml urea 5% bath Oil 500ml

This becomes a problem due to the presence of urea, which is only water soluble and we will not get processed in this oil environment unless suspended. Now this will not be easy even though you use the newer form of urea Ttz the powdered form. I have not done any search under the commercial badolies to see if there are any with urea. I suspect not because in order to be able to process urea deftig we should then add water and this becomes a W/O bath oil. The only remaining possibility then is suspending in an oil-middle, which is not evident.

In addition, there are a few other problems:

1. you write Eumulgin B1; I doubt that you will find this product yet. In addition, if you consult the Galenic formulary, you will determine that in Badolies Eumulgin O5 is used. The first is a PEG-12-cetostearyl alcohol ether and is an O/W emulsifier; The second is a PEG-4-Laurylether, which ensures the dispersion of the oil in the bathwater.
2. you write Comperlan COD; you will not find it though Comperlan OD; from COD I didn't know the existence.

There are 2 possibilities:

1. you call the prescribing physician and explain the problem with the urea. I suspect this will never be an elegant preparation! Commercial badolies would exist with urea???
2. either keep it (or the doctor) to maintain the urea and then use your urea powder and put a good "shake before use" on the bottle.
