Question
Posted on: March 6 2013How do I prepare: cetyl alcohol 22.5 g glycerin 20g NaLS 1g Aqua 35.5 g Me-nicotinate 1g glycolsalicylate 8g turpentine essence 5g Eucalyptol 2g camphor 5g
< br/> In this preparation there seems to be no problem at first, but if they are longer, there is a separation of the oil phase. How can we avoid this?
Answer
You have a lot of oil-soluble ingredients in this compound. In order to better emulsify them, it is better to provide a solvent for these, namely liquid paraffin. Given the amount of glycerin is quite high (usual 10%) I would replace 10 g of glycerin with 10 g of liquid paraffin. You can proceed according to the classic method in which all volatile ingredients are dissolved in the liquid B. Paraphernali. . This solution is added to the partially cooled but still liquid CR è EME.
