The conservative situations generally result in for a longer period than desired processing situations. The usage of controlled nucleation for these kinds of formulations can dramatically cut down processing time. Experiments carried out at Baxter Health care using a 5% sucrose solution counsel which the processing time is usually lowered by up to 25 h at a laboratory scale (Table (TableII).
