Are there oil soluble chealators
Are there oil-soluble chelators that are used in cosmetics industry?
If so, what are some examples worth checking out?

I don’t think there are. The interaction between metallic ions and chelants in cosmetics is ionic in nature, for what you need a protic solvent, which in our case is water. Also, the metallic ions you want to protect your products from are completely or partially soluble in water, so you need your chelant to also be soluble in water.

…what @ketchito said…why would anyone need a chelant in an oil base? What lipid-soluble metal constructs are a threat and what lipid-soluble ingredient might be compromised? I cannot think of ANY need to use one in a medium like that. Can you elaborate?

Not to protect the product, but rather there is a specific oil I want to use that are good for a certain skin condition, but for an individual who has high metal contents in hair or scalp, but this oil is suspected to react fast (within hours) with metals and create funny smell; hence I wondered whether there was any oil soluble chelators to capture metals on scalp once this oil was applied.

Maybe your seeing rancidification - that can be accelerated by some transition metals - esp. copper iron zinc tin reportedly via free radical formation. I know this is a problem the food and biodiesel folks experience. Maybe try some antioxidants but i know the chemistry isn’t that simple and some might make it worse. On the scalp makes it even ore complicated with the human and bug enzymes.
Curious - How did these folks get some much metal on their scalps?

Rancid due to oxidation, yes. I did try vitamin E but that did not help. Though another antioxidant may work, I doubt it because the smell lasts a long time once applied (ex, a week or more) even after washing and it seems the original oil pulls out metal from hair/scalp and the metals kind of sit there despite washing, and then continue to react not with the original oil that was used, but with human sebum. People have higher metal contents due to various reasons. Some lack certain vitamins (esp. vitamin B) that help the process of removing heavy metals from the body. Others may be continuously using some products or eating food that have higher metal contents. I personally did one of these hair/scalp metal test and found aluminum was higher than normal/average. And I of course reacted rather badly with this oil as well.

If you need to incorporate a chelator, is it an option to emulsify your oil of choice into a cream using something like BTMS50? Or maybe suspend the chelant into a whipped hair butter that is solid at room temperature…using Shea butter, cocoa butter etc to increase the melting point?
