  Help with hair conditioner/leave in formula viscosity

  Posted by nicole1505 on January 11, 2025 at 5:04 pm

  Hello, new here!

  I am developing a 2 in 1 conditioner and styling cream formula, which I need to be moisturizing but light because it is rinseable and leave in at the same time. I have a problem with my formula: The emulsion forms well, and has a good consistency, until at the end I add my preservative Euxyl k712 (NCI Name: Sodium Benzoate (and) Potassium Sorbate) and the viscosity drops completely.

  Please does anyone know why this happens and what I can do to stop it from happening?

  PS: The reason I add the Euxyl k712 at the end is to add it at less than 40 ºC and with a pH less than 5.

  Thank you!!

  Formula:
