Step 48

In college, you most likely had done soap making in your Chemistry class. The whole process is Chemistry guided. In a typical laboratory, the crude soap is made through base hydrolysis of the fats and oils producing glycerol and the anionic surfactant soap that is composed of potassium and sodium salts of fatty acids and oils. It is made by reacting vegetable oils and/or animal fats to a strong alkaline solution of sodium hydroxide or potassium hydroxide (both commonly known as lye).  The whole soap making process is called saponification.

You can try different soap making by varying the fats and oils ingredients. Saponification has two processes: hot process and cold process. One of the essential differences between hot process and cold process is the exploiting the fats and oils’ saponification value. Cold process involves analytical techniques to precisely and accurately measure the amount of lye to be used. The amount is dependent of the saponification value of the fats and oils being used. Not enough lye used can result to greasy soaps while excessive lye can cause skin irritation due to higher pH.

Equipped with the right knowledge, soap making is now made easier and exciting at home. For those who want to make a coffee soap for the first time, you will need the following items; 113 grams each for coconut oil and olive oil 227 grams of soy bean oil, 142 grams of coffee (instead of the typically used water) and 57 grams of lye (take precautions as sodium hydroxide is a caustic solution, it is better to wear protective eye glasses and gloves)

After you completed the required things, it’s time to make basic white soaps.

•    Weigh the desired mass of the coffee and lye in different pitchers.
•    Pour the lye into the coffee, try to prevent them from splashing.
•    Gently stir the mixed solution using a wooden spoon, then cool to approximately 100° – 110°F.
•    Heat all oils, melt if some of them are solid, and cool to 100° – 110°F.
•    Make sure that the temperature readings for both lye solution and the oils are similar or with very slight difference. Pour the lye solution in a thin stream fashion into the oils; don’t forget the continuous constant stirring.
•    Keep that constant stirring. The mixture will eventually thicken and trailing will be obvious. Do this for less than an hour. Apply essential or fragrance oils and coffee at light trace if it’s suits you.
•    Using a plastic mold, place the formed crude soap there. Cover and envelop with towel.
•    Keep it in a warm room for approximately 2 days.
•    After that, take out the soap from the plastic mold and you now have the coffee soap block. Cut to blocks into bars with a knife.

Soap making needs large amount of time to completion. But it is still nice to wait for the coffee soap to be finished. With coffee soaps, you can now clean your hands with that stinky kitchen smell.
