    I need help with below formulation for color protection shampoo 

    Phase A
    Deionized water      q.s
    Sodium gluconate    0.2%
    Gel Aqua                   2%
    Glycerine                      3%
    Phase B
    Decyl glucoside          15%(8.25) 
    Sodium cocoyl glutamate 10% (3.9) 
    Coco betaine               10% (3.6) 
    Cmea     5%
    Phase C
    Amodimethicone         2%
    Dimethiconal                2%
    Silk protein
                        2%     
    Keratin                             2%
    Preservative (euxyl k712)  1%
    Fragrance oil                  0.3%
    Citric acid                        0.1%

    Is heating cmea with surfactants best way to dissolve it? I find it difficult getting the right viscosity. Any suggestions on bettering this formula for colored hair?

    Remove glycerin and decyl Glucoside.
    Increase glutamate to %20 or more

    They reduce the viscosity. 
    I wouldn’t use cmea more than %1or 2.

    These surfactants are nearly impossible to thicken. Even crothix won’t work with cocoyl glutamate. Your only option is gums.

    See if you can replace cocoyl glutamate with sodium lauroyl sarcosinate 20%. Increase coco betaine to 15%. Bring down CMEA to 1 or 2% (may not even be necessary). 
    Now I think you can thicken with salt and CDEA 1-2%.
    Also check if silicones are affecting your viscosity. 

    I dont think glycerin is going to help with color protection or anything.

    What is Gel aqua?

    I dont have access to sodium lauroyl sarcosinate..gel aqua is liquid carbomer..so with sodium cocoyl glutamate??Padmavathi said:
