Highlighter Formula Problem.. Need advice!
Hello everyone, I am a newbie to this forum! I have always had a passion for make up and have a understanding of ingredients used to create cosmetics generally. I have been researching and formulating my own pressed highlighters for a while now. I have run into a problem though, once I have let my highlighters dry slightly I press them and get a nice smooth finish, but upon swatching them and using them for a few uses I have began to notice it develops a strange holey/cracked looking texture. I am not sure if this is normal? or if this is due to a kink in my process of creating them.
For example: maybe I have added too much binder and not incorporated it into the mix properly. Also if this is due to me not mixing them problem, Shall I mix them in a coffee grinder first? I am currently mixing them in a small metal bowl.
The finished product isn’t extremely powdery only slightly.
I will attach some images so you can see how it looks, I would really appreciate some guidance on this! and thank you for reading.
I am also thinking to add Dimethicone 350 to my formula to help with the binding process..
Ingredients: Mica’s, Titanium Dioxide, Magnesium Stearate, Kaolin Clay, Carnauba Wax, Sericite Mica, Zinc Stearate, Isopropyl Alcohol, Caprylic/Capric Triglyceride, Phenoxyethanol & Ethylhexylglycerin.
