    hi I don’t think your Cetyl Alcohol + polysorbate 80 is coursing the instability’s.
    The Stability of surfactants formulations depends a lot on the Order you add
    the different surfactants especially if you use a Cationic (polyquat7) with in
    an anionic system that can lead to instability’s.

    Polysorbate 80 is the culprit. DEL that and reduce cetyl alcohol & glycerin to 125 gms each and you’ll be fine.
