How long is Scooty cream safe to eat after its opened?

[YouAreTheWeakestLinkGoodbye]

The title says it all really. By Scooty cream I mean the cream you get in a can with a noozzle to sprays it out .

About a week maybe two tops it should have an expiration date on or a best before date (i call its farty cream) puts some people right off all the more for me lol

Thanks LMH20, I does have a best before date but that is a long time away , I thought it might say 'once opened consume within 1 week' or something along those lines.
