What Is Cold Process Soap?

By Mou ·

Cold process soap is made the traditional way: by combining plant oils with lye and water, then letting the bars cure over several weeks.

The method, step by step

  1. Plant oils and butters are blended with lye and water to begin saponification.
  2. Essential oils and natural additives are incorporated at the right stage.
  3. The soap is poured into molds, then cut into bars.
  4. Bars are cured for weeks, allowing excess water to evaporate and the soap to mellow.

Why cold process?

  • It preserves the nourishing glycerin naturally created during saponification.
  • The long cure produces a mild, creamy lather.
  • It lets us choose every oil, scent, and ingredient with intention.

The result is a gentle, long-lasting bar that feels good on skin and is made with care from start to finish.
