Preparation of Materials

Caustic soda solution, 36 deg. Be (30% solution): Dissolve 2 kg caustic soda in 4.6 liters water. Cool to room temperature, check the concentration with the hydrometer, adjust (if necessary) and filter if needed before using.

Additives: Dissolve salt, soda ash and sodium silicate in 1.4 L of water.

Preparation of the Soap

1. Measure or weigh carefully the required quantity of coco oil.
2. Weigh the lye or caustic soda solution required (5 kg) and add slowly to the oil, stirring continuously for about 30-45 minutes until it attains the condensed milk-like consistency.
3. Add the measured amounts of dissolved additives and CDEA (foam booster) with continuous stirring from 5-10 minutes more. Then add the essential oil with stirring. Stop stirring when the mixture attains a viscosity similar to condensed milk.
4. Pour the homogenous viscous soap mixture into the moulder, allow to set at room temperature for 12 hours or until soap solidifies.
5. Cut the soap into bars of suitable sizes with a string or wire attached to the wooden/metal cutter. Twenty-eight (28) bars will be produced. The soap is white or creamy white. Cut bar into 4 pieces and pack in a plastic bag.
6. Allow to age from 7 to 10 days to complete the saponification reaction.
