What is the estimated shelf life (assuming you keep it in a dark place) for:
1)herbal infused olive oil? coconut oil?
2)herbal infused vinegar
3)herbal extract made from 50% glycerin in water (and would you refridgerate it to prolong its shelf life?)
3)does food grade beeswax even have a shelf life?
Thanks for any help you can provide.
Update: Thank you! I should have specified olive oil infused with dry herbs, not fresh-- I think it keeps for significantly longer, especially in the refrigerator, on account of the neatly absent water content. The herbal academy of ne site says to use only dry herbs because of the risk of mold, and to discard it after a month. I thought that might be excessively careful, but I guess not. By the way my main focus is not cosmetics, but rather "dietary supplements " for health purposes, made from edible ingredients and foodstuffs. If they taste, smell, and look good, so much the better!
