Brain Octane Oil eating plastic coffee lids and styrofoam

Can someone please tell me why Brain Octane Oil splits plastic coffee lids and styrofoam cups. How dangerous is this for our own bodies?

    Hi @kfadel
    It's not just Brain Octane, other oils do this as well.
    This older thread has more info;

    I presume you saw the ~warning info on the bottle.

    fake it till you make it

  • Thank you for responding. I think it’s obvious we didn’t read the label, hahaha. I have been using your product for 6-9 months and wether it be in combination with my Keto way of living or it’s own merit, I am enjoying the seemingly beneficial aspects. So much so that I give it to my dogs as well!

    However, my husband, who is health conscious as well, is now freaked out and isn’t convinced this can be good for us if it eats through porous items. I haven’t mentioned the following to him; the only side effect I have from drinking it is my throat immediately becomes scratchy and it causes reactive coughing. Just a cough or two. What information can you provide me that would put his mind at ease and back to using your product and what explanation do you have for the itchy throat only when I drink it?

  • HDPE and travel mugs
    I suspect this MCT-plasticizer issue is a much bigger issue. I have been using a brand of no-spill travel mugs where the dispense button would fail after a few months. We finally looked closely at the barrel of the button (what pushes the mechanism in the lid back) and found a pair of hairline cracks down the sides of this structure that seem to make it impossible to repair. Looking at a few other broken ones we still had - same kind of cracking. I used to blend this mixture in bullets - eventually, the blending cups and/or the seals would break down after a few months. Think of that, the blending cups. Likely the rubber seals were being attacked by the MCT oil to some extent too (these do wear out in bullets). Other uses of the same gear, with hot fluids but no MCT, no problems. Anecdotal but curious.

    I have used silicone bottles to carry mct oil on travel. I don't know the chemistry of silicone bottles but this article
    suggests it is probably not going to be a good container for long term use.

    HDPE is ok tho? It seems to be what the industry uses to manage coconut oil. Does anyone have any leads to known products using HDPE, particularly good travel mugs?

    Otherwise, it seems like the only way to deal with this is to stay strictly with stainless steel and ceramic mugs
    for drinking, and transport MCT oil in glass or stainless jars.
