Question
Posted on: March 6 2013What can be best added to give next suspension lotion UG a minimum of stability: down-cut sulfur 7g salicylic acid 5g sulpho resorcinol 5g alcohol 94 ° 20g Aqua
AD 100ml < br/> We thought of adding HPC 400 1% and a double amount of ALC to keep the soluble products in solution. Should disinfectant alcohol be retained or is it better replaced by isopropyl alcohol?
Answer
In most cases, Aerosil is added 2% combined with 1% Veegum to such suspension. One does not opt for a mucous compound because of the sticacity. Whether a doubling of the amount of antiseptic solution will be sufficient to keep 5g salicylic acid in solution can be tried out. But I doubt it. Given that the doctor prescribes ethanol, we will keep it!
