Why do the bottles containing the liquid products pinch in or swell up? Is it still good?
Our products rely on natural, organic ingredients. They would be denatured (made ineffective) by sterilization. Microbes from the air or in the product themselves, “cycle” in the bottle. Depending on the microbes and the phase the product is in, the oxygen and nitrogen in the air at the neck of the bottle can initiate and keep this cycling going. The liquid products when contaminated really, really smell awful! Actually, they are still good as microbes will cycle the contaminant eventually. So, if the stuff is just kind of sweetish, cheesy, smelling dont worry how the bottle looks. If you can hold your nose there, all is OK. After opening, cap tightly and refrigerate it for literally unlimited shelf life. If your are unsure, uncomfortable, or whatever, well be happy to replace the product to your dealer for you, rather than have you worry or have you gag bringing it back to normal by aerating it.
