Source for digitonin?

I use digitonin as a detergent. I've usually got it from Sigma, which
sells a low-purity version "recommended for use in aqueous solutions".
On heating this stuff, it dissolves, more or less, in water.
Unfortunately Sigma is backordered on this until forever, and I really
want to get my experiments done. I tried a much higher purity product
from Boehringer Mannheim, but it didn't dissolve in water even on
prolonged boiling, and when I tried using it anyway my results were
ireproducible at best.
Does anyone know either another source for the aqueous digitonin, or how
to reliably and safely dissolve the high-purity stuff in water?
Thanks for any suggestions.
