    Hi guys, thank you so much for your response! Really helpful :) 

    Well, I’m only a student and was given this topic by my professor to work on.A lot of botanical variety including green tea, prickly ash, etc are gaining interest due to studies which hint at their UVA targetting abilities to combat skin cancer and photo aging.

    Hi!

    I am preparing a sunscreen containing green tea extract and ZnO. My question is, how do I adjust the pH? Cause, ZnO needs a pH between 7.1 to 7.5 but green tea extract (with EGCG) would require a lower pH. Any ideas? Please do let me know! :)

    Alright :)
    But in general,when we get the required HLB, is it alright if we use a combination of both water and oil based emulsifiers to meet the required HLB?
    Thanks!

    Or can I used a combination of both oil and water soluble?
