  • Can glucosides really work as emulsifiers?

    Posted by Gunther on November 7, 2018 at 11:20 pm

    After reading a lot and finding some say yes some say nay
    Does it?

    I tried pouring
    olive oil 1 wt%
    generic decyl glucoside solution 10 vol% (about 5.2 active decyl glucoside)
    stir
    then add 20 vol% water
    stir

    It became quite cloudy
    After a few hours some oil droplets separated on the top.

    Maybe glucosides work as emulsifiers but 5.2% active decyl glucoside was way too little to properly emulsify olive oil, which is as non-polar as it can get.

    Decyl glucoside is surface active so would act as an emulsifer. Your issue with separation is likely due to the lack of stabilisers in the continuous phase and the methodology. 
    Also I wouldn’t say olive oil is a non-polar oil. Try squalene or squalane.

    In my experience, yes, it does work. You’ll want to check your HLB values and required HLB values first before setting up your experiment.

    My experience, you always need a co-emulsifier with those. They will work, just not alone. Olive oil is quite the polar triglyceride, as CriticalM mentioned, BTW.
