Kodak HCA packages - Expiry 2012 - safe to use?

Tom Kershaw · Jun 22, 2014

I can't see any reason why 2 packets dated Oct 2012 and 1 packet June 2012 shouldn't still be fine to use, they've been well stored. Is there something I've missed?

As long as the bags contain no punctures and the powder has not clumped then it probably is safe to use. There is really nothing in the formula that can spoil.

I mixed up the June 2012 package shortly after posting the earlier message and the powder was absolutely fine.
