Posted on: March 6 2013How do we make a stable emulsion with next composition?
Menthol 7.5 g chlorbutol 7.5 g hamamelis water 90 g disinfectant alcohol 90 g perhydrosqualone 24 g polysorbaat80 9g< br/> Attempt with Lanette SX if emulsifier is not stable
Answer
I suspect that the large amount of rubbing alcohol is at the root of your problem. Of course, if necessary (if the concentration is sufficient), it can take care of menthol and Chlorbutol. In addition, it also makes for a cooling effect and therefore I do not change it! I suggest increasing the viscosity of the external phase of the emulsion by adding 1 to 2% KLUCEL GF, which is well soluble in alcohol.
