As far as I am aware, the primary differences between the various purity levels relates to quantities of residues such as sweat salts (from the sheep), pesticides, etc. The dihydrocholesterol content should be very similar. I would guess that any odors present in lanolin would probably be due to sweat residues, but that's just a WAEG.
