  Hi

  I am formulating a hair color developer 6℅ with hydrogen peroxide 50℅. I have some questions about it and would be happy if so. guides me:

  1- how to make a buffer system with H3PO4 to keep pH between 2-3. (All info on the net is about how to make a buffer in water with no other ingredients). And is it important to use buffering agents in this system?

  2- How to measure the stability of the H2O2 in the developer cream. Is not it dangerous to put in it an oven in 45’c for 2 months?

  3-How to determine the shelf life of the product?
