Question
Posted on: March 6 2013W/O cr è me breaks through LCD salicylic acid 4% liquor Carbonis detergent 6% betamethasone dipropionate 0.01% AVA cr è me ad 300g
I first heated the AVA cr è me together with the LCD. After friction of this CR è me with salicylic acid on the ointment plate, however, the CR è me broke. Addition of extra Arlacel has not helped. After adding after lauryl sulfate we got a stable cr è me.
Answer
Of course, nalauryl sulfate stabilised the CR è me but with the result that a W/O became an O/W. You can better be in a tarred (note the tare weight) mortar + Stamper + spatula LCD mix with 10g starch and the whole dry vapors, possibly with a hair dryer. Then pour the dried powder onto a clean weighing sheet and bring the Betamethasone dipropionate trituration into the mortar. Then mix it with the salicylic acid and the starch mixture. Once everything is mixed well you rub the whole with AVA CR è me to "Tarra + 300" G.
