Clover is the supplier.? It lists the product name on a page I didn't share initially (attached below).? However, it is interesting they omitted the dye.
?
But Roy makes a good point about older datasheets possibly not including all compounds of interest.? Here is one from 2013.? This one includes 'alkyldiol' which they have listed as proprietary.??
?
This one also has Food Black 2 listed.? Acid salt #3 indicates the dye is neutralized as a salt.? But which salt they aren't disclosing. Link is below.
