Hi Genius chemists here
I am making simple basic lotion for myself. i am also adding 5% titanium dioxide and 5% zinc oxide just to use this lotion as moisturizer and sun block at the same time
My question is 5% titanium and zinc is ok to use as sunblock or should i increase the percentage
My formula is really simple as follows:
EDTA (as chelator)
Preservative (will be using phenoxyethanol or phenonip or optiphun) plz suggest which one is best to use in this simple formulation.
