What is unopened liquid foundation shelf life?

I want to order a bunch of my liquid foundation on line before it is all sold out, it is a discontinued brand. My question is, how long can I shelf this foundation? Can they stay good a long time if unopened? or do they still ';spoil';?What is unopened liquid foundation shelf life?
I'm not an expert, but I did just what you're talking about and ordered a bunch of discontinued liquid foundation. It had to start out more than a year old, because it's been discontinued for at least that long. I keep the bottles in a box in a cool room (usually 65 degrees or less, depending on the time of year--a bit warmer in the summer) wrapped in either plastic bubble wrap they came in when shipped, or in the blister card package if they came that way. I'm actively using them with no problems, and planning to order more. Again, I want to stress that I'm not an expert, so I don't mean to dispute what articles or experts advise. So far, I've had good luck with mine, and I'm devoted to a discontinued liquid foundation, so I feel your pain! :-)What is unopened liquid foundation shelf life?
3 months is the limit or else it will be an ugly cakey orange.
