Royalty Rosin is a solventless extract, meaning that no solvents were used in the extraction process. It is commonplace for this type of rosin to be made from bubble hash that was created with freshly frozen/live bud. This process allows for the terpene profile of the source flower to make it through the extraction process for a fuller flavour. In comparison to a solvent-based extraction, this process requires no purging time at all as there is nothing to purge from the newly created extract.
