    thank you @Pharma i learn a lot from you and other members.
    i work as a marketer my knowledge in chemistry is very basic.
    i hope i could give something i know back to the community even tho it wont be much because every ones might have their own marketer already.   

    sorry for my previous post.
    they use Carica Papaya Fruit Extract in soap bar so the enzyme itself must be very low.

    Well then, let’s rephrase that one: Cosmetics, a statistically significant correlation between $$ spent and perception of how beautiful people think they’ll become…
    Honestly, sometimes, just sometimes, I wish I were on the sell rather then the know side. My TV is probably half the size of yours… :smiley:

    Polyhydroxy acids (PHA) are trendy now. They said to be more gentle than AHAs (read less effective too). Gluconolactone is actually used in Lotion P50, I however think that it’s the lactic acid that does the main job there.

    @Pharma - One of the main reasons there aren’t more cosmetic scientists with their own product lines is because to create a successful line, you have to believe the BS you are selling. That’s hard to do when you know too much.

    Hi all, first post so sorry if this is in the wrong place. I see this ingredient ‘Ananas Sativus Fruit Extract / Pineapple Fruit Extract’ listed in a number of cosmetic products. Does anyone know how this differs from Bromelain? Most definitions say it contains Bromelain but if it does, and with Bromelain losing activity in water (slower in oil) then these additives probably have next to no effect by the time the consumer uses it. Am I missing something?

    @lushderma - I’d suggest you start a new discussion.  Click the button on the right column to do that.

    I developed and marketed a papain exfoliant. It didn’t sell.
