Preparation of Materials
1. Caustic soda solution, 32oBe
Dissolve 0.855 kg of caustic soda (NaOH) in 2.4 kg water. Cool to room temperature. Check the concentration with the hydrometer. Adjust if necessary and filter if needed before using.

2. Additives
Dissolve EDTA, citric acid and salt in 100 mL water. For color, make a 1% solution. Add color in oil.

Preparation of the Soap
1. Weigh carefully the required quantity of coco oil. To make a colored soap, add about 10 mL of the 1% color in oil solution or the amount to suit the desired intensity of color.
2. Add the required amount of caustic soda with stirring until the condensed milk-like consistency is attained. This usually takes 45 minutes to 1 hour.
3. Add the dissolved additives and continue stirring for 5 minutes more.
4. Add the light mineral oil, CDEA and scent. Stir for another 5 minutes.
5. Pour the soap mixture into the moulder. Let it stand at room temperature for 12 hours or until soap solidifies.
6. Remove soap from the moulder and cut into desired size.
7. Stamp and pack. Allow to age for about 7 days to complete the saponification.

Preparation of 38oBe Caustic Soda
Dissolve 1 kg caustic soda in 2 liters of waters. Cool to room temperature. Measure the concentration with a hydrometer. Adjust (if necessary) and filter if needed before using.
Procedure
1. Weigh all the ingredients
2. Melt separately the stearic acid and coconut oil at 80oC.
3. Add castor oil first before adding lye into the charge oil
4. Mix caustic soda with alcohol; add slowly to fat charge with stirring. Temperature should not exceed 75oC.
5. In a separate container, dissolve sugar in water at 80oC (remove any froth)
6. Add to the soap mass, the glycerol, the water-sugar solution, and the CDEA stirring constantly.
7. Cover and allow to stand until temperature reaches 60oC, add perfume and color (if needed).
8. Transfer to mould or frame.
