  Waterproof eyeliner stability issue-separating

  Posted by Shannonho on August 10, 2020 at 3:43 pm

  Hi,

  Thanks for read my question first. 

  I am making a liquid matte waterproof eyeliner, it’s an extreme thin formula, has to shake before use, but the separation looks pretty bad, a white layer on the top, I really want to solve it.

  I am using ACRYLATES COPOLYMER as thickner, AMINOMETHYL PROPANEDIOL as neutralizer, the pH is at 7.5, I have 22% of black iron oxide and 8% of silica, roller mill together and add 30% STYRENE/ACRYLATES/AMMONIUM METHACRYLATE COPOLYMER at the end, it’s cold process,everything looks good and after shaking, application is smooth, but is there any way I can solve or reduce the separation? 

  Let me know if you have any questions and thanks for the answer.
