  Pilling issues with rheology modifier

  Posted by seaberry on February 27, 2021 at 10:11 pm

  Hi! I’m working on a serum with Aristoflex AVC (ammonium acryloyldimethyltaurate/ vp copolymer) and Sepimax Zen (polyacrylate crosspolymer-6) and we are having some issues with pilling. 

  The formula is basically

  75% water
  10% actives
  8% oils
  5% glycols
  1% aristoflex
  1% preservative

  The Aristoflex feels great but we have some electrolytes in the formula, and about half of the test batches separated. Thus, Sepimax Zen is the most recent addition at a 0.6% concentration. Now, it pills like crazy under moisturizer, sunscreen, foundation, anything. Are there any ways to mitigate this issue? We’re trying to avoid silicones in this formula and keep the number of ingredients as low as we can.
