I see this all the time in ingredients listings. They will let a detergent and in parentheses put from coconut oil. But to make coconut oil into detergent, turns it into something as natural as plastic…lol

@Katherine – yes, they do call it antifreeze, but non-toxic antifreeze. An important distinction, though I’m not I’m convinced it’s been proven safe in a way that could allay fears of what effects it could have on the body. Thanks for the correction. It is reflected in the blog.

@Jim – thank you! I really appreciate the guidance. I read it wrong. I adjusted the blog.

2,2-bis(bromomethyl)-1,3-propanediol is not the same thing as 1,3-propanediol, as is shown in the chemical name. And to say that 1,3-propanediol is “synonymous” with ethylene glycol is forgetting that these aren’t just words, but three dimensional molecules. They exist in different three-dimensional shapes. This means they behave differently. So if you were to ingest antifreeze, your body would be poisoned. But 1,3-propanediol doesn’t look the same to the 3D enzymes in your body. So it’s not poisonous.

Having said that, as with any newly created substance, we still need to do more research to make sure it’s safe. But citing research that refers to an entirely different chemical and highlighting part of the name that matches the subject of your article is misleading.
