  • Rice Bran wax vs Carnauba wax

    Hello Chemistcorner people,

    I just made an o/w emulsion with rice bran wax instead of carnauba wax and I noticed it was much creamier and softer than the carnauba wax formula. Is this due the fact that Rice bran wax is a superior oil binder, thus creating more stable and creamier emulsions? I also added a little bit glyceryl stearate. But not so much, arnound 1% more, but substituted all my holding waxes for rice bran wax, so that’s around 12% worth of rice bran wax. I am curious to know what special benefits rice bran wax has for making creamy and stable emulsions.

    Looking forward for your thoughts on rice bran wax!

    Entirely different carbon chain distribution there. The homolog array makes a big difference in tactile, emulsification, fluidity. Carnauba has more higher carbon chain constituents, plus sterols, ester waxes. Feed it through a chromatograph and you’d see many more peaks than rice bran wax I’ll wager.

    Hello what did you mean by  homolog array? The molecule size/length?

    You’re using 12% rice bran wax and 1% glyceryl stearate for a lotion? Per usual, we need the whole formula in your OP to be helpful. That’s a lot of wax and
    … I guess a normal amount of glyceryl stearate but low if it’s (one of) your primary.
