What's your favorite Thickener for Shampoo?

I've made the same shampoo and increased the viscosity different ways and they all seem to work well. I was curious what other people's favorites are and Why? Or any other tips for this formula are always welcome.

Sodium Chloride didn't work out well most likely because the Coco-Betaine increases the sodium level already. To close to crashing the curve I think. 
So, I tried Xanthan Gum, Cellulouse, Increasing Coco-Betaine, etc... All do the trick, how do I choose the best way lol?!

Water 70%
Alpha Olefin 15% CocoB 5% SLSA 2% Coco Hydroxy 2%
Glycerine 2%
Amodimethicone 1%
Sodium Gluconate .2
Glycol Stearate 1%
Panthenol .5
Marketing Extracts and Oils .9% total. 

Thickener 1%

  • If all do the same trick, and there is no performance issue nor stability issue, I'd go for the cheapest and easiest alternative for the manufacturing process.

    @em88 that is the million dollar question. we who are stuck in the boondoe's have to be very creative in sourcing raws at affordable prices and everything for non sulfates are expensive and big MOQ's. i sometimes wish @Perry would do a good webinar on just this topic
  • My favorite lately has been Glucamate VLT.
  • @globalwidget that is 40 USD a kg and MOQ is 200kgs. Delivery is 6-8 weeks locally :-(

    PEG-150 Distearate, Aculyns from Dow, Stearamidopropyldimethylamine, and so on.

    The celluosics work pretty well.  HPMC and HEC.  And Carbomer EDT 2020 is helpful too.

    Got a sample of this a few days ago. Hope it is not very expensive.

    I guess everyone has this issue, especially with big companies of raw materials (excipients). They have big MOQs and high prices. 
  • @em88. the carbomer ETD2020 is about 18 usd/kg here. I will get some tomorrow and run a batch to see if i can thicken up the shampoo
  • Thanks everyone. For the record the xanthum test had sedimentation separation after 9 days. 
    Looks like I’ll stick to Perry’s suggestion and the cellulous. I use HEC and so far so good, although It’s a little annoying to work with.
  • @Dustin what was the annoying part for you? 
  • FekherFekher Member, Professional Chemist
    @Dustin @Perry what is the best level of HEC can be used in shampoo to give  the best viscosity ?
  • I have noticed that HEC has many incompatibilities. 
  • FekherFekher Member, Professional Chemist
    @em88 what are the incompatibilities with HEC ?
  • PerryPerry Administrator, Professional Chemist
    @Fekher - There is no simple answer to that because the level you use depends on the viscosity you want, the quality of the surfactants you're using, the other ingredients, etc.  Anywhere from 0.4% - 1.5% might work for your system.

    Thanks for that smart answer @Perry

    On page 14 you will find a list of substances that are not compatible with HEC.

    I usually try to avoid HEC when formulating shampoos.

  • @em88 what do you use? I am not having good thickening with the peg-150 and am struggling to get something that gives a nice thickening effect. got some HEC and wanted to try it today 
  • FekherFekher Member, Professional Chemist
    Thanks @em88
  • Got some good results with Arlypon TT today

    in my experience high-viscosity grades of HPMC work exceptionally well, especially with sulphate-free shampoos ones
    UK based formulation chemist. Strongest subjects: hair styling, hair bleaches, hair dyes (oxidative and non-oxidative) I know some stuff about: EU regulations, emulsions (O/W and W/O), toothpaste, mouthwash, shampoos, other toiletries
