What you should be looking for is HFC134a, or Tetraflurothane on the ingredients list. 152a works too, though it exerts a lower pressure than 134a which means less shots per magazine, weaker slide action, and lower FPS.
I've used Blow Off to great success in the past, though lately, I've sold off all of my plastic slide GBBs because propane is much cheaper than duster gas and I've experienced all around better performance with propane.
