SOAP MAKING BY COLD PROCESS

White creamy laundry bar soap with the essence of citronella or other suitable essential oils.

Materials:

• Coconut oil (primary)
• Caustic soda (35 Be) as saponifying agent
• Sodium silicate as soap builder
• Essential oils as perfume
  
  

Equipment:

• Cylindrical soap mixer, pedal type (16 liters)
• Moulder with cutter (71.5 cm. x 38 cm. x 3 cm.)
• Oil storage container, 20 kg. capacity
• Percolator, 1 gallon capacity
  
  

Procedure:

Five liters coconut oil is measured and transferred to a steel cylindrical soap mixer. A volume of 2.3 liters of caustic soda is slowly added to the oil with stirring for 20 minutes. 0.25 liters of sodium silicate and 0.02 liter essential oil are added and continuously mixed and stirred for 10 minutes. The homogenous viscous soap mixture is poured into the moulder and is made to stand for seventy-two (72) hours at room temperature to complete saponification. The soap is extruded from the mould and is divided into bars by passing through a wire cutter. Soap bars are packed in polyethylene bags then into boxes for storage.
