Small quantities of Larostat 519, an anti‐static agent, were added to four samples of a commercial organic powder which was giving flowability problems believed to be caused by electrostatics. The effects on standardised bulk densities, on the Hausner Ratio, and on the behaviour of the samples when exposed to various controlled relative humidities in an experimental rotating inclined pan, were significant, and are reported and interpreted.
