Hello everyone! This is my first post here, so hopefully I’m not exposing myself to be too much of a fool.
Essentially my question is this: is there something (obvious) wrong with the following hypothetical sunscreen formation?
The goal would be to create an anhydrous, mattifying sunscreen with okay-ish skin feel and broad-spectrum coverage. I’m not sure how much of the C12-15 alkyl benzoate would be necessary for adequate pigment dispersion, and I understand I may also need something to aid with pigment suspension. I may also have to add a tint to reduce the white cast.
Still, aside from all of that I sense that I’m missing some very major reason(s) this would fail. Any thoughts? Thanks in advance!
C12-15 alkyl benzoate
Zinc oxide, nano, coated (HP1 Z-Cote)
Dimethicone/vinyl dimethicone crosspolymer
Roughly, the procedure would involve heating the C12-15 alkyl benzoate and dimethicone/vinyl dimethicone crosspolymer, adding the zinc oxide and TiO2, homogenizing (as best I can with a vortex mixer, that is..), adding silica, and mixing again. I’d check homogenization with a light microscope.
