  KBT also has some carbonate in it.
  Kodak T-8 is similar to KBT but of lower concentration.

Kodak Polysulfide Toner T-8

Water 750.0 ml
Polysulfide (Liver of Sulphur) 7.5 grams
Sodium Carbonate, monohydrated 2.5 grams
Water to make 1.0 liter

Papers will tone in 15 to 20 minutes at 68F or 3 or 4
minutes at 100F.
After toning rinse prints for a few seconds in running
water. Then immerse the print for about 1 minute in a
solution of sodium bisulfite bath consisting of:
Water 1.0 liter
Sodium bisulfite 30.0 grams
 Then wash prints for at least 30 minutes.

   According to private communication with Doug Nishimura of
IPI T-8 is suitable for protective treatment of film and
prints.
   KBT is available and I agree its much more convenient to
use it.
