    I am looking for any suggestion of RM that could help me to formulate water resistant pressed powder.
    I did some trials with dimethicone  treated pigments, lauroyl lisyne and magnesium myristate. I got higher hydrophobic level but never get complete repellency.
    I will appreciate any response.

    You won’t get “complete repellency” unless you essentially treat the powders yourself. What is the purpose of having completely repellent powder? The majority of formulations work just fine with the commercially available treated pigments and excipients.

    The way I understand, the latest trend is for waterproof and sweat-proof make up. It suppose to last through all kind of daily activities, together with vigorous exercises and with swimming.
    So  pressed powder needs to be water repelant  and have extremely good skin adhesion.
    How do you mean, that I could “treat the powders myself”?
    Also, I was wondering, that maybe it would help to incorporate some volatile silicones and than “baked”?
    Any other ideas?

    Any kind of advice I give will be dependent on what scale you want to operate at: Hobbyist, garage-level manufacturer/seller, or small/medium scale business.

    The first thing to consider is that there’s a huge difference between using “completely resistant” powders to make up a product, and having your finished product be waterproof/sweatproof.
