  • thickener for oil blend

    Posted by chemnc on March 25, 2017 at 3:35 pm

    I have a blend of oils that is very nice but could use some thickening. I’ve never used an oil thickener. I read in one of Perry’s articles that Silica, Bentonite, and Magnesium Aluminum Silicate could work. Isn’t bentonite really heavy?

    Cationic bentonites (Bentones) make very fine dispersions in liquids.

    Ethocel 100 premium could be useful too.

    Thixin R should work

    I agree that Thixin R (or other brand of hydrogenated castor oil) should work.

    I doubt that Ethocel 100 would be suitable  for this purpose as it is not soluble in aliphatic oily materials.

    My previous reply here was a specific answer to the query on bentonite clays. From my own experience, I have found these materials very difficult to work with and they do not give a visually appealing effect.

    Some grades of Versagel (Penreco) may be suitable for your uses if you need a transparent product.

    @johnb Ethocel 100 Premium is exclusively to thicken and gel oils especially Octyldodecanol and other oils with Octyldodecanol.

    I am corrected - thank you. I obtained my information from a general data sheet For Ethocel rather than the one devoted to the Premium 100 grade.

    Bentonites, when properly activated, do really well in pigmented systems as thickeners and pigment suspenders. I agree with @johnb that to just thicken clear oil as a finished product, they won’t be nice looking, or particularly stable.
