How to prepare Next cream: Carbomeer 940 0.5 g Vaseline 9g water 8g Propylene glycol 2g Lanette N 3g VL Paraffin Wax 2.5 g capsicumoliehars 3.3 g DMSO 75g

(total = 103.3 g) < br/>

Answer

Reservations:
  1. The ratio of the amount of water to the amount of DMSO is poor and unusable; an emulsion will never be able to be formed. To my knowledge 50g DMSO is on a total quantity of 100g creme The maximum that is described in the literature (FNA).
  2. Lanette N turns out to be no good emulsifier for this case.
  3. I suggest following composition:
    Carbomeer 1 g
    cetostearyl alcohol 7.5 g
    cetomacrogol 1000 1.5 g
    VL Paraffin wax 6g
    propylene glycol 5g
    vaseline 11.5 g
    Water 20g
    DMSO 46.7 g
    capsicumoliehars 3.3 g

Preparation mode:
I would suggest the cetostearyl alcohol together with the Cetomacrogol, the VL paraffin wax and the petroleum jelly to melt on the hot water bath. In that molten mass the carbomer nicely to disperse and only then add the heated water. This CR è EME let's cool down and in the meantime we mix the capsicumoliehars and the DMSO into a mortar. The cooled CR è me we mix in portions with the DMSO; After each addition is mixed well with the pestle.
