  • Why fatty alcohol ethoxylates ain’t used more often in personal care products?

    I have been experimenting with some Lauryl alcohol ethoxylate - 9 EO and found it much better than glucosides. 
    It doesn’t reduce viscosity as much or leave a sticky afterfeel.
    It’s quite non irritating.

    Makes you wonder why it ain’t more widely used in personal care products.

    The process in which they are made are not natural/organic friendly.

    Yes, glucosides are only being used now because of the natural story you can tell in marketing. If performance was the only factor important in formulating, I doubt anyone would use glucosides either.

    On the downside it’s hot process only, higher cost. I buy 7m 90% sol, it remains liquid even at low temp. Totally worth it.

    Gunther, linear alcohol ethoxylates are used primarily in HI&I surface cleaners where we have used them forever, not in HBA products, because hey have a higher irritation potential. Otherwise these would be used because they are cheap, effective hydrotrope-surfactants, and they have little or no residual 1,4, dioxane.. I’ve been saying the same for years regarding gemini surfactants, which are safer & better: why haven’t cosmetic chemists used these more? They just don’t know I guess. Look into Colonial Chemical’s surfactant array for some.
