Oil Soap

In this project, I had made soap with oil, water and NaOH, and it so easy.

I’m sure that everyone can do it.

First looking for this reaction. In this Saponification

reaction show that we have to use 3 moles of NaOH to make an Irreversible reaction

then looking for the molecular weight of oil. In this formula, I use coconut oil and olive oil (12:8) because coconut oil is made soap has good cleaning and coconut oil can help to relieve dry skin.

molecular weight of coconut oil => 279.6

molecular weight of coconut oil => 330.5

let’s calculate

coconut oil 20 g. = 0.0715 mole

mole = mass (g.) / Molar mass (g./mol)

= 0.0715 x 40

= 2.8612

2.8612 x 3 = 8.58 g. (NaOH 8.58 g. per Oil 20 ml.)

- Coconut oil 12 g.

- Olive oil 8 g.

- NaOH 8.58 g.

- Water 15 ml.

- Beaker

- Stirring Rod

- Pot

- Hotplate

1. Add NaOH to water and stir.

2. Then pour it into a beaker of mixed oil.

3. Wait for 3 minutes (for Saponification).

4. Stewed it for 2 hours.

5. After that, put a soap out of the beaker and leave it for 2 days.

6. Done!!!
