    Right. I am surprised they use so little, I wouldn’t have thought it would have any effect at 1%

    In  the US it’s an active ingredient so if you claim against it you have to provide extra claim support. Our best seller is at 1% and the clinicals are great I’ve seen people with almost debilitating eczema have relatively rapid relief.

    inactivation rate for papain appears to be 10 minutes at 83C.

    Update: I have tried papain but at any reasonable concentration it doesn’t seem to have any effect.

    Now working with potassium hydroxide. Interesting. I have managed to hydrolyse it and now have a tan coloured, very viscous, fluid with some remnants at the bottom. I will allow solids to separate out for 24 hours then separate and neutralise the fluid with citric acid. I should end up with hydrolysed oat protein and potassium citrate.

    Didn’t need 24 hours. I decanted 90% of it leaving the remaining undigested solids. Then I neutralised it with citric acid to pH=7. Interesting: the tan colour changed back into the colour of oatmeal. The result is a gum, with foaming properties. I painted it onto my left arm and let it dry. It left an invisible film with skin-smoothing properties.
    I think I am going to make a larger quantity of this, say a couple of kilos, and test it in hair and skin products, beginning with shampoos and conditioner.

    @Mike_M 

    How do you test for colloidal
    oatmeal in the final product?

    I get my fine powdered oatmeal from the supermarket in the bakery section. I also couldn’t get the whole particles fine enough with a mortar or a kitchen blender.
    Maybe there are supermarkets or bakery shops over there aswell that sell the fine powder? 

    I see you already have a solution. As fine as talcum, nice!

    @Belassi, sorry I now see it’s an old thread.
