  • PEG-150 DISTEARATE AS THICKENER IN SHAMPOOS

    Posted by Lab on January 24, 2023 at 5:23 pm
    I got into my hands a product developed by the technical area of a company, more specifically a “natural” shampoo thickened with PEG-150 DISTEARATE, which didn’t seem to work very well for me. The information I have is that COCAMIDOPROPYL BETAINE and DECYL GLUCOSIDE were also used as surfactants (I don’t have access to the complete formula). So, the questions I raise are:
    - Is there any incompatibility between PEG-150 DISTEARATE and one of these surfactants (or other raw materials that come to your mind)? Found nothing in articles…
    - What is the best way to use this thickener in transparent “natural” shampoos? Are there any combinations that can increase your efficiency?
    I was informed that the process is hot, melting the PEG 150-DISTEARATE before pouring it under previously heated water. I believe that the surfactants are added during heating, but in a separate search I found information that there are formulators who add PEG 150 DISTEARATE directly to the surfactants… would that be correct/functional? I never tried it this way.
    I did some prior forum searching and found this thread, but from what I’m told PEG-150 DISTEARATE is the only thickener in the formulation.
    Thank you all for your time and patience!  :)

    I will start with 0.5%.
    Decyl glucoside reduces viscosity.

    I will add it at the end after everything else has been mixed.

    Thank you for the reply! I’ll try to reproduce the same shampoo and see if it stays the same or better

    I do not think decyl can reduce viscosity, it just not thicken enough so I suggest lauryl glucoside to give higher viscosity
