    Interesting because you can clearly tell the difference between cetyl and cetearyl (I haven’t tried Behenyl alcohol myself).
    I believe the cetyl/cetearyl difference is that the former is more homogeneous than the later, so the crystal emulsion structure, hence the feel is different.

    Just curious….which feel do you prefer….between cetyl and cetearyl?

    I prefer cetyl as it has a more smooth feel.
    But cetearyl emulsions are reportedly more stable.

    You definitely need to buy small amounts of each one and try them both for yourself.
    Experimenting is key to succeeding in cosmetic chemistry (and any chemistry field too). You can only get so far by reading without experimenting yourself.

    Thank you for your comment…Yes I agree…. I have tried Cetyl, Cetrl Palmitate, and MM, in the same formula, and definitely preferred the Cetyl Palmitate to the other two! :)
