hardening
  • Recommended maximum 50% of total oils.
  • High palmitic/stearic — accelerates hardness and can crack if overused.
  • Slows trace.

Unsaponified oil remaining as superfat.

Post-saponification NaOH salt

Sodium Tallowate

Declared soap after sodium hydroxide saponification.

Post-saponification KOH salt

Potassium Tallowate

Declared soap after potassium hydroxide saponification.
