  What’s wrong with my formula?

  Posted by Reno21 on December 13, 2023 at 2:38 pm

  I’ve been able to emulsify this body butter formula in 1-6 gallon batches, but I cannot in 10 gallon batches.

  The formula is:

  Water - 56%

  Glycerin - 4%

  OliveM 1000 - 6%

  Shea Butter, Cocoa Butter, Almond Oil - 31%

  Cetyl Alcohol- 2%

  Euxyl 9010 - 1%

  Euxyl l 9010 is a broad-spectrum preservative that is effective against both Gram-positive and Gram-negative bacteria, no?

    If you stay long enough around here, you will learn that nothing is really “broad spectrum” and it is sort of marketing term. Euxyl PE 9010 might probably work in anionic surfactant systems, but not really in emulsions.

    Preservative blends, supportive ingredients (such as chelating agent, humectants [1.2 Hexanediol, Pentylene Glycol, …] and low pH will help.
