I am using a BP/BPC formulation for Mist Alba or Magnesium Sulphate Mixture.
0,06% Methyl Paraben
0,02% Propyl paraben
40,00% Magnesium Sulphate Heptahydrate
5,00% Magnesium Carbonate light
0,02% Peppermint Oil
I am getting a hard cake formation on stating that is very difficult (unacceptably) to disperse on shaking.
This appears at face value to be a simple formulation.
I have added the parabens to the formulation to preserve better.
Any suggestions on additions or production advise
