Hyplus 100 MSDS Chemical stability listed as Unstable

[Lukew]

Currently looking over MSDS for a variety of ink sets and noticed that under the # 10 chemical stability & reactivity information section. Toyo Hyplus 100 says chemical stability "Unstable".
Near every other ink MSDS I've seen says either "stable" or "stable under normal operating conditions"

toyo's 2008 hyplus 100 msds lists it as being stable under normal conditions.

What does this mean for the humble printer? perhaps nothing?
Would it not be better for an ink that is subjected to various other chemicals to be listed as "stable" ?
Could this "Unstable chemical stability" cause issues on press?

Be interesting for any in the know to chime in.

Am I the only one that finds it odd that an ink is classified to be unstable & materials found to be incompatible with this ink are water, alcohols,acids?

How can this ink be used if the very make up of the fountain solution is incompatible with the ink.

MSDS terminology and normal usage don't really have anything to do with each other. The incompatibility on the MSDS has to do with storage, firefighting, health and transportation rules. Much of it is "boilerplate" to protect the manufacturer. The reaction of water, acid, alcohol, and ink is in very small amounts whereas in storage and transport it could be 100's of pounds/kilos.

I would question the unstable as that is very unusual. It would have to be done by contacting Toyo.
