Abstract
|
|
|
|
The mixing of salicylic acid and wheat starch powders was studied using a V-type mixer. After the optimum operating conditions of the mixer were examined, the mixing characteristics relating to dilution ratio, particle size of active ingredient and addition ratio of lubricants were investigated. The coefficient of variation was expressed by a power law relating to the dilution ratio and the particle size of active ingredient. Furthermore, the comparison of results with the theoretically estimated values of mixing index suggested that the mixing of cohesive pharmaceutical powders is a complex stochastic process and cannot be explained fully by a simple theory based on a complete random mixing.
