What is the approximate shelf life for herbal infused olive oil, coconut oil, glycerin, or vinegar?
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!

Straight 100% glycerine AKA glycerol will last decades on the shelf. It contains no water, and does not tend to pull water out of the air (hygroscopic). 50% glycerol with water will have a water activity of around 0.8 (Fig. 1) At 0.8 you likely won't get pathogens, but will get molds.

Shelf life: 2 years for peak flavor.How long will herb Infused olive oil last?
Infused olive oil does not have the same shelf life as regular olive oil. Refrigerated, cold infused oils will keep for about a month before losing their flavor. Hot infused oils will keep for about three weeks to a month.How long does store bought Infused olive oil last?
Infused olive oil will last for about 6-12 months, depending on whether there are any fresh ingredients such as garlic inside the oil or not. It also depends on how you store it, as refrigerated infused olive oil will typically last longer than if you leave it out.How long do herbal infusions last?
Infusions are delicious warm or cold and can be sweetened with honey or any other natural sweetener. They keep for 2-3 days in the refrigerator. To make a decoction, place 2-4 tablespoons of the dried herb in a pot and fill with water, making sure to cover the herb well.How long does homemade Flavoured oil last?

Answer 2
For 1), it is 2 hours. See Infusing olive oil with herbs: infused olive oil is not a shelf stable product and the same rules as cooked meat apply to it. 2 hours on the shelf, 3-5 days in the fridge. The type of oil doesn't matter. As soon you have plant matter where the oxygen is cut off, you risk botulism (can be deadly even if treated properly).
For pure coconut oil, look at the date stamped on the package. This is what is relevant for food safety purposes. If you are asking "when will it go rancid", there is no way to predict it. Just smell it before use.
Herbal infused vinegar will last the same as other vinegar. It is safe for years, unless you notice signs of spoilage (mold).
Pure beeswax also lasts for years without becoming unsafe.
All of this is for each of the exact products you mentioned above, unaltered in any way. For example, if you were to emulsify together the infused vinegar, the beeswax, the coconut oil, and some water, the resulting shelf life would be again 2 hours outside of the fridge, after which it would be unsafe for consumption. Or, to say it another way: the storage lifetime of a prepared food is not determined by the storage lifetime of each ingredient.
