Someone happened that a conforming cream after 3 years has lost consistency?
Thank you very much! -

Emulsions are not stable. They separate eventually, and creams are not supposed to have shelf life of 3 years.

Thank you very much.And how much should they keep on average?

One year

If cream passed 3 months stability test at 40 C, what will be its duration?

It’s impossible to tell like that. Too many variables such as type of container, ingredients used, production conditions etc. Also are you talking about stability of the emulsion or stability of active ingredients? Emulsions can stay stable for more than two years. It’s doesn’t mean you should use it.
