Should Arlacel 83 be added to next preparation? Elocom lipophilic Cream 20g erythromycin base 1g Cold Cream ad 50g

Upon review of the qualitative composition of Elecom Cr è me it seems to be of the O/W type. So we are having an incompatibility. So it should first be asked what type of CR è I want! The answer will determine which emulsifier is necessary. If O/W is desired, it could be that no additional emulsifier should be added and you get the desired result by performing the preparation as it is on the prescription. For W/O, Arlacel 83 will be necessary!
