This formula liquid soap is actually a olive liquid soap, this was the goal when his formulation, make a soap that had the highest concentration of olive oil. The soap is formulated as an exceptional quality hydration and wetting characteristic of olive. Can be used as hair and body shampoo. On the other hand, this high concentration olive complicates the process requires a longer cooking and there is always the risk of excessive turbidity, cloudly. The usual and easiest is to dramatically increase the amount of palm kernel, olive decreasing. Concentration of up to 70% is typical for liquid soaps resulting in an easier process but a product with excessive cleaning power, maybe a little aggressive and sure enough, with a fabulous amount of foam.
The safety equipment, goggles and gloves are essential and should always be used in handling of raw materials and the process.
This process is used a slow-cooker “crock pot” to perform the saponification reaction, which is a hot process “hot process”. This pan allows a more controlled, clean and safe. It could be used a system of double boiler or a gas oven or electric alternatives. The characteristic heating the pan Narita NSC-35 that was used in this tutorial is seen below:
As you can see, it’s a slow cooker heating whose maximum temperature is reached at 180 min and not exceeding 85°C in regulating high.
The entire process takes approximately 3 hours of cooking. The soap mass pass through several stages, accompanied by a characteristic feature in each phase. The trace is obtained very quickly and then gradually undergoes massive changes and changes appearance, reminiscent aspect: applesauce, mashed watery potatoes, mashed potatoes, vaseline lumps, vaseline creamy and vaseline translucent in the finally at the end of the saponification reaction of oils with potassium hydroxide.
Preparation of potassium hydroxide solution (potash)
Add potash slowly with stirring over the water. Never unlike because it may cause an accident! The solution temperature is maintained at around 60°C, as can be seen in the IR digital thermometer.
The mix of oils should be around 70°C.
Preheat the crockpot slow cooking for 10 minutes on high.
Place the mixture of oils heated in the pan.
Slowly stir with manual mixer, add the potash solution.
Operate the mixer and stir on the entire inner surface of the pot. This is time zero.
In 14 minutes it forms a heavy trace.
This aspect is similar to applesauce.
After 45 minutes the temperature rises to 83°C and appearance begins to change.
2 hours of cooking.
Formation looks creamy vaseline.
3 hours of cooking, the temperature rises to 94°C.
At the end of 3 hours it is this aspect.
Look for breaking the soap mass into smaller pieces to facilitate dissolution. It’s a job that requires time and effort.
Turn off the heat, cover and let stand for 18 hours (overnight).
Here the vegetable liquid soap is completely dissolved in the water dilution.
Weigh essential oils for the fragrance.
Allow to cool to 60°C and add the essential oils slowly with stirring.
After a week the product is stabilized and if there is a formation of foamy lumps or sediment, remove and the product is ready for use.
