Seeking direction from community, need resource for generic borax.
Finally got feedback from brand "20 Mule Team", now owned by Dial (soap), which in turn is owned by Henkels. I was sent to two websites which do not exist. Staff barely aware of their own product line. Downsizing in pursuit of economy, all intelligence squeezed out of the system.
AFAICT, all "Boraxo" products are blends, this from Dial source, verbatim: "Dial 02203 Boraxo Powdered Hand Soap 5 lb Box Specifications Capacity : 5 lb Packing Type : Box Weight : 5.60 lb Features A select blend of quality soap and borax that is gentle on hands."
Sent reply inquiry for bulk source, awaiting response.
