Breaking down mineral sunscreen
Does anyone know/have an opinion or a suggested place to research what is the best way to break down physical and or chemical sunscreens when they are on the face and body? Is one surfactant particularly good for this or a combination of things? I’d like to make a cleanser with this task as a focus. I find sunscreens really clog the pores. Thank you

Trick for not-nano zinc oxide sunscreens on babies: Use oil to soften it up and then wash away with shampoo. From a physico-chemical perspective, something like a waterproof makeup remover might work well, I’m thinking oil-to-milk cleanser.

Thank you @Pharma! I am interested in adult removal. I feel like it’s the biggest contributor to clogged pores/breakouts, especially water resistant formulas. They are so difficult to remove completely and I probably triple cleanse these days I was hoping I could figure out what would break them down the best and then create a cleanser with that. I appreciate your input and sorry for the tardy response. I didn’t see I had gotten a response.

Double cleanse. First step is, as Pharma said, oil to milk type of cleanser (makeup removing balm, see clinique take the day off), followed by foaming cleanser.

I second the comments pointing to an oil to cleanse. I make an oil cleanser (basically just oils with emulsifier and surfactants to help rinse-off). It’s still a work in progress but it’s definitely what I reach for when I want to get clean after a beach day with lots of sunscreen reapplications, especially for my face.

I made very basic oil cleanser based on croda’s formula. Basically it’s some ester like c12-15 alkyl benzoate, cithrol 10 gtis and polysorbate 80. Check out croda’s formulas but never add as much emulsifier as they call. They suggest 30% or more sometimes. Too irritating for eyes. But their formulas are very good starting point.
