Extracts used in sunscreens

Postby giftpraiya » Mon Oct 07, 2024 10:24 am

I would like to know that when we analyze the amount of important substances in an extract, when measuring the absorbance, do we have to put the concentration that absorbs a lot or a little light in the sunscreen? And the concentration of the extract that is put in the cream is the clear part that is filtered out, right? Or do we have to find the concentration of what kind of substance to put in the sunscreen?
