Answer
The fact is that chlorbutol will be melting point-lowering and may constitute an eutectic with salicylic acid (??). Other peculiarities do not attack me. As a possible solution I propose the preparation of three Cr è knife, which are mixed afterwards.
prepared
- Burow 25 g + Copper Sulfate 300 mg + Zinc Sulf 1g + AVA 150 g
- Salicylic acid 10 g + AVA 144 g
