The original Boger fluid was an aqueous solution, as were all the solutions synthesized until 1983, when organic Boger fluids were produced using a dilute solution of polyisobutylene (PIB) in a mixture of polybutene (PB) with a small quantity of kerosene oil added. From then on, most Boger fluids have been PIB - PB solutions. Other recipes include:
* polystyrene in oligomeric glycol (Solomon and Muller 1996)
* polyethylene oxide in polyethylene glycol (Dontula et al. 2004)
* polystyrene in dioctyl phthalate (Odell & Carrington 2006)
