Why is this happening when I inflate my bike tires now?

Question

First off, I use an electric inflator with a presta valve to inflate my road bike tires (to 120 psi). Lately, when the tires are finished inflating, I pull the tab back on the inflator nozzle and when I do that, the goo stuff inside the tires, like kinda explodes out a little. Why is this happening all of a sudden, its never happened to me before.
