Your best source of formulation information is expired patents, M. But this is not pancake batter that you mix up on a kitchen counter from a dollop of this and a pinch of that; the manufacturing process is hazardous from beginning to end and you need to retain an experienced consultant to assist in the plant and process design, not get a formulation from the internet. Good luck!
