What Is Laurel (Aleppo) Soap? Origins & Tradition

Why this ancient bar still matters today.

What Exactly Is Laurel (Aleppo) Soap?

Laurel soap is a traditional hard soap made from:

Olive oil – the moisturizing base

Laurel berry oil – prized for its herbaceous scent and clarifying cleanse

Alkaline salts (lye) – the natural catalyst for saponification

Water

When oils and lye meet, they transform into soap + glycerin (a humectant that helps skin retain moisture). Properly cured bars contain no free lye—just a gentle, balanced cleanser.

INCI (label) names: Sodium Olivate; Sodium Laurelate (from laurel berry oil); Aqua; Sodium Hydroxide (consumed in saponification); Glycerin (naturally formed).
