Consistency study of semi-solid pharmaceutical preparations.
The study of the consistency of a number of semi-solid pharmaceutical preparation, namely: simple ointment base, paraffin ointment base, emulsifying ointment base and soft paraffin (m.p. 47--49 degrees C) was conducted using an apparatus designed for the purpose in this laboratory. Factors such as temperature and shearing stress of motive force were taken into consideration. A mathematical equation was developed for the extrapolation of the results.
