Another factor to be aware of, which no one has mentioned is how the oils were treated before they came to you. As I live in New Zealand, we have few oils processed within the country. Has the oil I’m buying flown over on a plane or his it been in the sitting in a shipping container on a ship exposed to high temperatures. How long ago was the oil processed before you received it.

Do the suppliers you buy from know the date of when oil was extracted, do you guys ask that info? I’d be interested to
know 🙂

Another person from New Zealand,nice to know i am not alone. Pure Nature i have had no problems with but prior to knowing that we had soap suppliers in New Zealand i brought all my fragrances and Esential Oils from some amazing sellers at Etsy,and that was coming up 2 years now,i still have most of them as i use them very sparingly but i do keep them all in the fridge,a tip i got from some where,went to get my cucumber oil the other night and it was slightly hard so left it out for a couple of hours and it was perfect. While i do like Pure Nature i cant often get what i want although they are getting better.Are you going to enter the soap challenge? second attempt and it's in the oven. All the best Andrea

Here's a link to learn more about the shelf life of various oils:
OILS - SHELF LIFE

You'll find good info on chelators, as well as many other topics here:
DEEANNA'S SOAPY STUFF

I use both ROE and vitamin E (antioxidants), added to oils, in soap and other B&B products. I buy my ROE from Lotion Crafter. It is highly viscuous. For ease of use, I make up the following :
1 oz. ROE
2 oz. Jojoba Oil (long shelf life)
Use 1/4 - 1/2 teaspoon PPO (Per Pound Oils)

I've been soaping since 2004 and have never experienced DOS (Dreaded Orange Spots) in my soaps. (Not braggin', just sayin' ;)) For more info, see ROE SwiftCrafty.PDF attached.

As you may have found, overusing ROE, can actually promote oxidation of oils. This is a paradoxical effect called pro-oxidation. As in anything, it’s the dose that’s important. The usage rate is .05 grams per 1000 grams of oils.

So that appears to be a .005%, is that right? If I'm going to be calculating by percentages rather than grams?
