Posted on: October 14 2017How much% Cholesterol do I use as a w/o emulsifier?
Here the following preparation:
White Vaseline 100 g
Cholesterol
Aqua AD 200 g
My question? How much% cholesterol is normally taken as w/o emulsifier?
Answer
1 to 2% should suffice.
In Your composition I would replace the white Vaseline 10 g with liquid paraffin. This liquid paraffin should warm up to +/-90 ° C. In this warm liquid paraffin, the cholesterol is dissolved. Solving the entire amount of cholesterol takes time because cholesterol is not so well soluble; So the cholesterol should be completely dissolved. After that, you can gradually add 90 g of White petroleum jelly and then the purified water that you have cooked in the preceding and let it cool down to +/-60 ° C . This should give you a nice W/O emulsion type Eucerine Aqua.
