Cold Process Milk & Saffron Soap Recipe

Cold Process Milk & Saffron Soap Recipe
This recipe makes about 1 kg of soap and produces a creamy, moisturizing bar with a light golden color from saffron.

Add olive oil and castor oil.
Let oils cool to about 35–40°C.

Pour the lye solution into the oils.
Use a stick blender until you reach light trace (mixture slightly thick).

Pour the soap batter into the mold.
Tap mold gently to remove air bubbles.
Insulate and rest
