  Stearic Acid saponification results

  Posted by David08848 on September 13, 2020 at 8:14 pm

  If I have a Shaving Cream formula with a large percentage of Stearic Acid in the oil phase,  will using a high superfat range of say 10% cause the formula to become too stiff and firm because of the unsaponified Stearic Acid in it?

  Thanks!

  So this is what I have found so far online:

  “Stearic Acid

  Stearic acid is the
  saturated fatty acid or waxy solid used as a hardening agent or
  lubricant. This acid helps make skincare creams and lotions “spreadable.” This
  ingredient can be derived from animals or vegetables. Stearic acid can be found
  in many vegetable fats, such as coconut or cocoa butter.”

  I am wondering if the excess of 10% unsaponified Stearic Acid is what is making the formula too stiff and heavy?

  Thanks!
