The real-time monitors captured the occasional formation of secondary clouds, likely caused by resuspension of talc particles from skin or other surfaces. Measurements of aerosolized baby powder, face powder, and two adult body powders indicated that the median aerodynamic diameter of the talc cloud ranged from 1.7 to 2.0 m.
Reducing the particle size of a powder will result in an uniform distribution of particle sizes. The process of reducing the particle size is called comminution. In extemporaneous compounding, there are three methods of comminution Trituration is the continuous rubbing or grinding of the powder in a mortar with a pestle. This method is used ...

However, subsequent particle size distribution measurements indicated a mean diameter of 14.3 m for talcum powder particles, that is, much larger than the PM 2.5 talc particles observed by Conner et al. . These somewhat contradictory findings indicate the need to clarify the particle size distribution of commonly used talc products.

A. You will have difficulty getting a detailed particle size analysis using a series of screens, as the particles will vary widely from top to bottom. You will have powder ranging from as small as 5 micron to as large as 120 micron.
Particulate pollution in the past decade has been measured as PM10, that is particulate matter 10 microns in diameter or less, which is talcum powder size. Recently the focus has shifted to smaller diameter particles, PM2.5, which denotes all particles 2.5 microns and smaller bacteria sized. These small sizes are thought to be more injurious because they are deeply respirable, becoming lodged in
