need help with mineral sunscreen / pilling off when applying on skin
I’m formulating a mineral sunscreen and i’ts been a nightmare lol
I’m using a combination of titanium dioxide and zinc oxide and a combinationg of hydroxyethylcellulose and xanthan gum to stabilize. Turns out it gets lumps all over the product after cooling down. Plus, when we apply it on the skin it seems to be pilling off, so frustrating!
I’m thinking it can be the gelling agents, but i’ve worked with both of them together before and had no problem; does anyone here ever had this kind of issue? or have any ideia of what can be causing this?
I appreciate any help/suggestions! Thanks
