What is the composition of ice types in nullsec now?

What is the composition of ice types in nullsec now?
I was just told that isotopic ice was removed from all nullsec, as if isotopes are now only being dug in the empire. This is true? What is the composition of the ice in the nullsec now?

Sorry for the mistakes, eng in not my native.

Isotopes are still available in null sec. The belt composition is still the same as before with Isotope ice, Dark Glitter, Gelidus and Glare Crust.
