alt Hacker NewsYou could say the same about cryptographic signatures where each party only knows a part of the key, yet those all work fine. You could probably piece together the formula by a sum of some employees and some external suppliers if everyone broke their NDA, but if people keep their word, your factories could just as well see shipments of "Ingredient A" and the worker only knows how much to add to each batch.

I wonder how much information leaks through something like Material Safety Data Sheets.
Real life ain't abstract math. You have MSDS 'mulmen mentioned, but I also can't imagine any factory being able to just mix shipments of ingredients "A", "B", "C", etc. without the actual content being documented on purchase orders, OSHA reviews, etc. You may want to operate in secret, but at the very least, the taxman really wants to know if you aren't skimping on your dues, so there should be plenty of relevant documents in circulation.
