  • Phenoxyethanol turned green

    Posted by antmagn on May 27, 2019 at 6:48 am

    Hello, does anybody know if this is normal, or if it has happened to you before? I have put phenoxyethanol in the fridge and it turned green and looked like separated, half transparent and half oily green….Is it dangerous to use it?

    Have you tried taking it out of the fridge and letting it warm back up to room temperature?

    Personally, I have never seen something like this happen before. It may be wise to throw it out if you cant figure out what happened to it.

    Where did you get it from? That doesn’t sound like you have phenoxyethanol.  No, I would not use it. It may or may not be dangerous but it is unlikely that it still works.

    Phenoxyethanol should be translucent with a light floral/rose scent. It has a freezing point of 14 degrees C. I have never seen it separate, or become green, and quite often find it frozen when shipped during winter months. It should have been frozen solid in your fridge. I would throw it out.

    I left it out of the fridge and it turned transparent. It has slight yellowy-green tint but it can be seen only on white.
    This is where I bought it: https://www.manischemicals.com/en/preservatives/299-phenoxetol.html
    There is also a certificate at the attachments tab.
