Lab scale Mixer for xanthan gum and water
I am making a roll-on deo formulation and for its aqueous phase I have to use Xanthan gum for thickening. I dispersed the gum first in a little glycerin and then added water which gives smooth aqueous solution with honey like consistency.
Now here the problem is, taking small batches (10-20 ml) in a test tube and shaking with hand gives very good results but when I go for big size (lab scale) batch, such as 250 or 500 ml of aqueous solution, a simple stick blender is not at all being able to move or mix the solution!
What type of Mixer I should use here? Any suggestions about a Mixer to be used for such application??
Thanks in advance,

power drill with a propeller attachment, or kitchen aid cake batter mixer. Think outside the box and I’m sure you can find something.

Thank you! Your first suggested option was already in my mind and now I will try both of your options.

Based on my experience, spiral propeller worked better in making creams compared with dispersing homogenizing blade.
For HEC gels I have only used the spiral propeller, not sure if other type of blades would work better.
@Perry, what is your experience with blade paddle and umbrella type blade? -
@em88 For HEC gels I’m using blade paddle with high shear revers flow 100 kg mixer with very good results

Thank you Perry, em88 and Lahav for your kind suggestions!

@Lahav, Thank you for your feedback. I will try the blade paddle too and do a comparison.

Hello friends,
In my search for finding an efficient Mixer for Xanthan gum and such other viscous solutions, I just came across one video which seems to be a very interesting option for this type of task and I thought I should share it with you people.
Please have a look at this video and leave your advices & comments. It has very simple but quite efficient blade design and the mixing intensity…..is awesome! 😮

Seems to have a very effective impeller design since it draws from all parts of the surface without even being orbited. If the price is OK I would buy it myself.

I cannot open the video/link!

@zaidjeber,
I had written the www link in my last posting but somehow it appeared as a direct video visual. Anyways, u can search “Xanthan gum 2% powder wetting in water” in Google videos and you will get it. -
