  • Laureth 7 - a PEG?

    Posted by cossci21 on July 31, 2018 at 7:05 am

    Hi Everyone,

    Is laureth-7 a PEG? I didnt think it was but have found some Dr. Google stuff out there that says it is or that the synonym is PEG.
    Using sepigel 305 and my client insists on no PEGs! Even though they are not nasty the internet makes them seem so.

    Thanks

    No, it’s not. It is an ethoxylated fatty alcohol. No polyethylene glycol on it. A little sticky if you use too much, but great material.

    I understand that dealing with ethoxylated alcohols or PEG, you will have the same concern of traces of ethylene oxyde and 1,4 dioxane

    Yes, it would not be allowed in a project under a Natural Standard as ethoxylated compounds are avoided.
    However, the real danger is minimal. The newer ethoxylated compounds have 1,4 Dioxane in minuscule amounts, generally at about 2 ppm. It is important to remember that it is not the presence of a substance that is the issue, but rather the dosage. In this case, the real danger is minimal. But as we all know that the natural standards will address these concerns.
