Help Suspending Lipobead Detox with Charcoal in a shampoo

Hello this is my first post, and I will appreciate very much your help.

Im trying to create a Clarifying Shampoo with the Lipobead Detox with Charcoal suspended
INCI: Cellulose and Mannitol and Hydroxypropyl Methylcellullose
Size: 700 microns

I have tried using Carbomer but it doesn't work  when I add the surfactants it loses viscosity.
I also tried Lubrizol Carbopol Aqua SF1 and it worked ok but needs 8% and its very expensive and hard to find for me.
Now with the Hydroxyethylcellulose the beads go to the bottom in 24 hours even when the viscosity is very high, could you please help me?


This is the formula

hydroxyethylcellulose

Disodium EDTA

  • @Heberth,
     1. Salicat MM : 0.5% is too high, out of regulation
    2. HEC can not suspend beads
    3. for saving cost, you can use Carbopol Ultrez-20, 1%

  • Methylchloroisothiazolinone (and) Methylisothiazolinone (Salicat MM)

    what you need is a surfactant-tolerant carbomer, e.g. Carbopol Ultrez 20/21; as you've discovered, HEC won't help suspend particles

    if you go down this route I strongly suggest taking out the quaternised guar as well, it'll make things a lot simpler

    Thank you very much for your help, I will try Carbopol Ultrez as you mention and also reduce the Salicat MM.

    Thank you, didn't know about the allergic reactions my provider sell it to me as a safer or more natural option to DMD hydantoin

    Methylchloroisothiazolinone and Methylisothiazolinone are used by many large companies including P&G and Loreal. It is only a problem for people who are allergic and when used in leave on products and in high amounts.

    There are many people who have a sensitivity to potassium sorbate which is also regularly used as a preservative in "natural" products.
  • Sodium benzoate at 0.4% and pH <5 has been totally reliable for me.

    In my country, we control CMIT/MIT amount as this link http://ec.europa.eu/growth/tools-databases/cosing/index.cfm?fuseaction=search.results&annex_v2=V&search. ordinal 39. For rinse-off only
  • Ultrez 20 is the best option for suspending the beads, i used in many products, and dossage will go approx 0.8 to 1.0 % based on your trial and error you need to finalize.
