How can I prepare a hair lotion containing zinc pyrithione with salicylic acid and hydrocortisone?

There used to be an alternative to Znpyrithione, namely the pyrithiondisulfide and which is soluble in alcohol and isopropanol of 70 degrees. This product would come out well because the other ingredients in this solvent also dissolve. Inquire at the wholesale trade for pyrithiondisulfide.
