Latest Patents
Rennie's most recent patent is titled "Process for the production of a deodorant or antiperspirant product." This patent describes a method for filling deodorant or antiperspirant soft solid compositions into dispensing containers through injection moulding. The process is conducted under pressure, ideally near the composition's normal setting temperature. The formulation is produced continuously in a screw extruder, specifically a twin screw extruder, which is controlled to deliver the composition in a suitably viscous state.
