How can I process benzoyl peroxide in the next solution? Benzoyl peroxide 100 mg/g salicylic acid 1 g spiritus AD 100 g

Answer

I only see one possibility and this is suspending with Hydroxypropylcellulose KLUCEL HF or GF as viscosities booster. Carbopol will probably not work due to the presence of salicylic acid. But HPC is compatible with spiritus and salicylic acid!
