  • How can thicken decyl glucoside??

    Posted by Sara21 on June 22, 2022 at 2:51 pm

    Hi
    I am working on a mild shampoo with glucoside but I have challenge to thicken this shampoo.I want to use natural thickener but xantan gum separated. I tried HEC and it’s separated too.
    Formula
    Water 64%
    PQ-10  0.1%
    Lauryl glucoside 10%
    Decyl glucoside  20%
    Citric acid   
    Sodium Banzoate  0.5

    @Sara21

    The glucosides being non-ionic are very difficult to thicken … gums are your best bet.  I would switch from Lauryl Glucoside to Coco Glucoside and you will probably have better luck.  Lauryl Glucoside is very viscous and that is probably what is settling out of solution.

    Yeah, HEC is no very good in surfactant systems. I have tried to make it work several times - always a fail! 

    Xanthan Gum is, however you need to process that correctly. 
    As Mark said, glucosides are hard to thicken and Lauryl especially. 

    Frankly, I don’t like the feel of only glucosides. I believe you should add at least some amphoteric surfactant. :)

    Lauryl glucoside needs heat. 

    Just heat it, mix it and cool it. It will gain viscosity. 
    Decyl is difficult to thicken.

    As Paprik said, use this shampoo, if you like it then ok. If you didn’t like it then no need to find out how to thicken it. 
    Change the formula completely.

    Use Cocoamide mipa or something similar.  Lower or remove Decyl glucoside and use just for bubble effect. Choose different surfactants.

    @Sara21 You could alternatively replace PQ-10 by Guar HPTC at 0.2%, which will also help a bit with your viscosity (there is a special grade for clear products). And don’t forget to add disodium EDTA to boost preservation.

    When are you adding the xanthan gum and the PQ 10?

    I have used Hydroxypropyl Methylcellulose to thicken APGs.  Try at 1%

    I use sodium lauroyl lactylate and lauryl glucoside together, you have to melt them but once they cool down they thicken without any gum or whatever…

    @MarkBroussard
    Yes you right .I eliminated lauryl glucoside in this formulation and it’s thicken easily

    Yes you right about adding amphoteric surfactant I did that too :).

    I realized that using just non ionic surfactant is not a good idea

    GHTC is not compatible with non ionic surfactants in my experience. It’s never disolve and separated

    @EVchem
    Actually the first thing that I add it PQ-10 and the last thing is xanthan gum

    It is perfectly fine with non-ionic surfactants. Are you processing it correctly? GHTC needs acidic environment to hydrate properly.

    @Sara21 I would reverse that order and put xanthan gum in first, PQ-10 you could reserve a small amount of water and add that as a premix last

    Yeah.because I didn’t had an anionic surfactant in that formulation even after dispers GHTC  in water and adding citric acid to get 3 or 4 ph but after a day my shampoo separated.

    I’ll add here that xanthan gum: anionic resin while polyquaternium-10: cationic resin. These two do not make good dancing partners.
