How much % Xanthan Gum for serum?

Hi guys, I am making a serum but have run out of Siligel, which is what I normally use, at 2%. I can only get hold of Xanthan Gum, as a substitute.

Can you advise me please, how much to use?

Many thanks.

    There are different grades of xanthan gum, they all thicken differently. If you can get spec/ or a coa  for something you can purchase look for a test on viscosity. Usually there will at least be a percentage they put in solution and you can see what result they got. 

    Even though there is variation, for most grades I'd use anywhere from 0.2-1.0 %
