How To Make Laundry Bar Soap

Posted by Manny on April 17th, 2008

laundry bar soapMaking laundry bar soap can be a good business idea. You can also make laundry soap for house hold use so you will not have to buy it in the market. Below is the procedure on making the laundry soap made from coconut oil which is the main ingredient. Other materials needed can be bought from chemical stores or from ultima entrepinoy.

Materials/Ingredients (for 28 bars)

  • Coco oil – 8 kg
  • Caustic soda solution, 36oBe [30% solution] – 5 kg
  • Soda ash – 90 g
  • Salt – 48 g
  • Sodium silicate – 400 g
  • CDEA [coco diethanolamide] – 40 mL
  • Citronella oil – 20 mL
  • Water – 6 L


  • Plastic pail – 16 L cap. [2]; 20 L cap. [1]
  • Hydrometer, 0-70oBe
  • Weighing scale – 10 kg
  • Wooden stirrer/manual or electric mixer
  • Moulder
  • Cutter
  • Spatula, stainless
  • Basin (large)
  • Graduated cylinder

Preparation of Materials

  • Caustic soda solution, 36oBe (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.

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

Procedure on making the Laundry Bar 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.

  34. Manuel says:

    @marlou amoguis gilbuena
    I think you can use coconut based cooking oil because it is already deodorized and doesn’t have the coconut smell and taste like virgin coconut oil.

  44. kasoma Hakim says:

    I got 1 of the recipes of making laundry bar soap but what is confusing me is: (caustic soda 360Be) explain to me what u meant by that.

  45. yeng navales says:

    Actually i have tried the above formula but its not so hand friendly
    (i mean it dries my hands after using)but with due respect… i suggest anyone can make a simple recipe laundry bar soap following the same procedure like the above. You can try it in small amount first then multiply it should it be successful.

    Basic Soap Recipe For Beginners

    Coconut oil 25 oz (prepared in a separate vat)
    Water 10 oz
    Lye 4.4 oz
    Soap colorant 2-5 drops (optional)
    Scent oil 1/2 tsp (citronella is most commonly used but you can try lemon, or sampaguita oil as well)

    This is a great soap recipe for beginners because it will harden relatively fast and have good lather right off.

    First. in a vat or pail or bowl, mix lye in to the water and stir well until it dissolves… of course take so much care in handling the solution. it gets hot, but as for me i let it cool.

    Pour the lye solution over the oil, and mix thoroughly until it lightly traces… then add the scent oil and the colorant. Stir again until it leaves a heavier trace. then transfer into your molder. Let the saponification begin and wait until its hard enough to cut. Then cut and let it sleep for 2 weeks… there you have your simple laundry soap.

  47. Musa says:

    why is it that my bar soap always appears dry and kind of perforated with air particles in it? it is also very hard after the maturity (after about 5 days).
