expiration dating for “natural, organic” formulations
What is your rule of thumb for assigning expiration dates on wholefoods, credo clean, sephora clean type formulations? We were thinking 2 years unopened after production date but 1 year after opening. Is this acceptable? My co worker suggested 3 years…

As @PhilGeis has mentioned numerous times, Period After Opening (PAO) is a useless term and standard.This would be established through testing. Each Formula could be different. You really can’t guess. -
@PhilGeis @Microformulation
I can appreciate PAO being a useless term…Since all of my stability is passing I was going to suggest… 1 year PAO. -
You’re marketing in EU? What are your chaolnege test stability data - assume in final market container?
-
To be safe I’d put one year after manufacture unless you have stability testing to show otherwise. Plus, that would encourage consumers to replace old products

@Perry- thank you
@PhilGeis-not marketing to the EU just yet. Challenge testing is being with no container. Is there a difference in doing Challenge testing with the container and without the container? -
To test, no but any challenge in stability should use product aged in container and with any implement packaged in product (e.g. mascara brush)/.
