Aniline Dye

[Bobby Nicks]

Anyone have any idea of the shelf life of the powder for water soluble aniline dye.

I have some powder that is 4 years old and I would like to used it. I believe it would be OK as it has been stored in a cool, dry place.

Thanks,

Bob

Under the storage conditions you describe it should have an unlimited shelf life.
