Soap is the basis of hygiene. Washing your hands regularly (and your body) limits the transport of harmful substances and bacteria. To meet this need, it is possible to make soap yourself with basic products. The chemical reaction to make a soap is called saponification and requires two reagents: a fat and a strong base. Here the fat will be coconut oil from the ripe nut (brown), and the strong base will be soda NaOH.
This tutorial will teach you how to make soap from coconut.
The first step is to extract the coconut oil from ripe coconut (brown nuts). Here is the procedure:
Once the extracted coconut oil can be measured the mass obtained.
This mass of oil will determine the amount of soda to be added to the oil and thus allow the saponification, that is to say the transformation into soap.
The soda used will be diluted in a given volume of water.
For this simplest step is to use an online calculator. It suffices to specify the nature of the oil used and its mass in order to obtain the quantity of soda and water to use.
Online saponification calculator
Note: In order to obtain the mildest possible soap for the skin, it is necessary to produce a surgras soap. The calculator directly proposes the quantities of soda to obtain a surgras soap at 5%, 10%, etc.
Overgrading is actually reducing the amount of soda so that the chemical reaction is not total. The unreacted oil then enriches the soap with the fatty acid and lowers its pH.
Safety instructions regarding the use of caustic soda:
Caustic soda is a product that can cause burns. It is therefore advisable to wear a minimum safety equipment.
Make sure to wear long clothing, gloves (nitrile or latex, laboratory) and safety glasses, well covered.
In case of projection, rinse with white vinegar, do not put under water. So always have a bottle of vinegar in range when you handle soda.
To mix two liquids, always pour the most concentrated in the least concentrated to reduce the risk in case of projection.
Once the equipment is on, you can start:
For this step there are two methods: cold saponification and hot saponification. The method of the video tutorial is cold, that of the photos on the opposite hot. Both methods are detailed here.
This step may take more than two hours. The two phases (oil and soda solution) will mix and then probably shift after giving a thick mixture. It's normal. Continue heating and stirring until the two phases mingle again.
