I was wondering whether anyone had any experience in DL Panthenol causing a cream to separate? I have 2 creams and the real only 'noticeable' difference in the 2 is the addition of the DL Panthenol. I add it to water phase between around 0.5 - 0.6% and use a stick blender (only for approx 1.5min) during emulsification step. I'm making approx 200g samples and don't have access to commercial equipment. The cream starts to separate when at 45C from about 2 weeks. Could it be the process or the DL-Panthenol? Thanks!
