  • Question for Shampoo formula

    Posted by SashaHayz on March 26, 2022 at 6:02 pm

    Hi guys ! I am formulating a Shampoo I’ve been trying to use Peg 150 as a thickener at 2%. However whenever I leave the Shampoo for a few hours the shampoo clumps up. Basically the Peg 150 separates. How do I get the peg 150 to stay in solution ? Also do you have any other suggestion for thickeners that is affordable and readily available ?
    formula ingredients 
    water
    decyl glucoside
    CAPB
    Peg 7 glyceryl cocoate 
    Peg 150
    polyquaternium 10
    Panthenol
    preservative

    Nacl or Crothix works best in my shampoo!

    Write the percentage and procedure.

    Decyl Glucoside has pH above 10 and looks like you don’t have anything to adjust pH with.

    Surfactant phase 
    decyl glucoside 15%
    CAPB 12%
    Castor oil 1.5%
    Peg 7 glyceryl cocoate 2%
    Peg 150 2%
    water phase 
    water 
    glycerine 2%
    polyquaternium 10 0.5 %

    Cool down 
    Panthenol 2 %
    preservative 0.5
    citric acid to adjust pH

    what I’ve been doing is to heat the surfactant phase to melt the peg 150 then take if off the heat and add the water phase. When it gets to 40 C I add cool down phase and adjust the  pH. The peg 150 dissolves while the mixture is hot but has it cools down it clumps up

    Unfortunately decyl glucoside doesn’t thicken with NaCl. I have some crothix I’ll try that.

    Mix surfactant with water, adjust ph, heat to 70°c, melt Peg 150, add it and keep temperature above 70 and use high shear mixer, when mixed cool it down and add cool down ingredients.
