    Hi, there! 

    I need to thicken the viscosity of my conditioner. Turns out that it is already finished… after scaling up the viscosity was not high enough. I surely will work on this formula again to fix that problem, but now I need to save this big batch first lol 

    What can I add in the finalized conditioner to increase its viscosity?

    I suppose it depends on the formula. Ours was a cationic surfactant / fatty alcohol based formula. When viscosity was low we would reheat to about 65C, run it through a homogenizer for a while then cool it back down. Sometimes that increased the viscosity.

    So is mine! 
    Here’s the formula:

    water qsp
    sodium gluconate 0,15%
    polymine bha 1,5%
    lactic acid 0,5%
    glycerin 2%
    btms + cetearyl alcohol 4%
    cetearyl alcohol 2,5%
    CTAC 2,7%
    jojoba oil 2%
    coconut oil 3%
    shea butter 3%
    gms 1%
    dimethiconol + dimethicone 3%

    the thing is, i used to work with another ctac, pure grade almost, but i had to switch to a blend with ctac + alcohol and the viscosity already decreased a little bit for a batch with 100, 200 g. but now for 5 or 10 kg didn’t get the right visco

    Hydroxylpropyl starch phosphate can be blended into the finished conditioner to give it more thickness, although it takes 24 hours to reach its final viscosity
