What is the equivalent USP phase of crossbond carbowax polyethylene glycol? Is it G16 only? Thanks!

It depends on the (average) MW of the PEG molecule
G14 (950 -1050)
G15 (3000 3700)
G16 (15000)

What is the USP phase for Carbowax 20M (20,000 MW)?
The smaller MW waxes have very similar characteristics, although they are not identical due to the different number of OH terminations according to weight.
