This cream with Dimethicone does not succeed

The composition is as follows: Cetostearyl alcohol emulsifying 45 g, glycerol 90 g, Rosewater Conservans 153 g, dimethicone 6 g, after lauryl sulfate 6 g DT 300 g Note: The purchased Rosewater contains Benzalkonium chloride and is therefore incompatible with lauryl sulfate, but even if I take it out I get no cream. The doctor had cream applied to the patient and who had the scent of roses, so contains the cream, which the physician possesses, Rosewater. For cetostearyl alcohol emulsifying I used Eumulgin C1000

Answer

Indeed the presence of benzalkonium chloride in the purchased Rosewater causes an incompatibility and it is therefore best to omit lauryl sulfate. Seen after lauryl sulfate is clearly in excess (the doctor adds another 6 G extra!) This will have little effect on   the cream but the preservative effect of benzalkonium chloride is at risk. So perhaps   best not to use after lauryl sulfate and therefore also no Lanette-wax.  

Eumulgin C1000 I (topical is the name Eumulgin B)   is synonymous with Cetomacrogol 1000 and therefore not for emulsifying cetostearyl alcohol. Self-emulsifying wax based on Cetomacrogol contains Cetomacrogol 2 D and cetostearyl alcohol 8 d. So for 45 g   We get 9 Cetomacrogol 1000 and 36 g Cetosteraylalcohol.
