Answer
You are dealing with an incompatibility between all 3 + and cetylstearyl sulfate which causes the O/W emulsifier to lose its effect.
I would switch to the following composition: Cetomacrogol 6 G; Cetostearylalchol (or cetyl alcohol) 24 g, liquid paraffin 2.5 g and water up to 100 g
According to the Merck Index, 1 g AlCl3 6aq (which is available) is soluble in 0.9 ml of water.
So we will put 25 ml of the freshly boiled water, which should be added to the melted fat phase, for solving AlCl3. This solution is added to the cooled cream under stirring.
An alternative to AlCl3 is already (OH) CL2, which is used for the same purpose, and is much less acidic. Can be purchased. Reimbursed by RIZIV???
