  Need help turning Vitamic C serum transparent

  Posted by HasanAskari on February 22, 2021 at 11:03 am

  Hi community, 

  I’m new to formulating and wanted to make my own Vitamin C serum. I borrowed a recipe off making cosmetics:

  Phase A (%)
  Distilled Water 89.40 
  Glycerin 3.00 
  Sodium Gluconate  0.20

  Phase B

  Resveratrol 0.50
  Caprylyl Glycol EHG (caprylyl glycol,
  ethylhexylglycerin)  1.00
  3-Glyceryl Ascorbate Glyceryl Ascorbate (40% aqua, 30% glycerin 30% L-ascorbic acid)  5.00
   Hyaluronic Acid (sodium hyaluronate) 0.70
  Xanthan Gum Prehydrated  0.20  

  I’ve switched MAP for glyceryl ascorbate and didn’t use Resveratrol in the below formulation:

   Phase A
  Distilled Water 89.4 
  Glycerin 3.00 
  Sodium Gluconate  0.20

  Phase B
  Resveratrol 0.50
  Caprylyl Glycol EHG (caprylyl glycol, ethylhexylglycerin)  1.00
  MAP  5.00
   Hyaluronic Acid (sodium hyaluronate) 0.70
  Xanthan Gum Prehydrated  0.20  

  The serum is cloudy and I want to turn it transparent. I was told a bit of PEG40 would help but that didn’t work. I noticed it initially turns cloudy when Caprylyl Glycol is added to phase A. Looking for suggestions. Reference picture:

  Swap your preservative for one which dissolves better in water.
