  • Shampoo viscosity is decreased after few days

    Posted by AbdulRahim on October 13, 2019 at 5:42 am

    My Anti Dandruff Shampoo contains 
    SLES 
    CAPB
    CDEA
    Glycol distearate 
    Lanolin 
    PQ7
    Zinc pyrithione 
    DI water
    Glycerine 
    J guar
    Silicoid 
    Di sodium EDTA
    Ammonium laureth sulfate 

    I am adjusting viscosity by adding CAPB. 

    Approx. Within one month after manufacturing Shampoo viscosity is decreased. 
    Plz discuss its solution.

    Reduce salt content 
    And use synthalen w 400 for stability and suspension

    1 Lanolin is useless, remove it.

    2 Same for glycerin

    3 What’s silicoid? A silicone? If so, how is it emulsified?
    4 Glycol distearate is tricky to use on its own, you’d better get a ready-made, ready to use pearlizer that’s already emulsified.
    5 Tetrasodium EDTA is easier to dissolve than the disodium one.
