What are the oldest ways to make homemade soap?

Soap has been around in my country for a long time. Many people use soap as a washing product. In everyone's childhood memories, do you think of old-fashioned soap? This kind of soap is often used to wash clothes, and it has a very strong alkaline taste and has a good decontamination effect. Now with the continuous development of technology, this old-fashioned soap is rarely sold in the market. So what are the oldest ways to make homemade soap?

First, what are the oldest methods of making homemade soap? Tools/Materials: lard (or other animal or vegetable oils). NaOH solution (commonly known as alkali). salt. water. A pot for cooking ingredients. Steps: Stir. Add water and alkali (NaOH) into the pot. After the alkali is completely dissolved, add the oil and continue heating and stirring. Saponification. After the ingredients in the pot boil, continue heating over low heat, stirring constantly to allow the oil to fully saponify. This process can take a long time, even a whole day. The higher fatty acid sodium produced in the process is the main component of soap. Salting out. After the materials in the pot have been saponified, add salt into the pot and stir to dissolve the salt fully to promote the condensation of the soap base. Let stand. Let sit for 3-5 hours. forming. Take out the materials that have been set aside. When taking the soap out of the pot, scoop out the upper layer of soap liquid and place it in a soap box (or mold) and wait for it to slowly solidify and take shape. After it takes shape, it becomes the soap base. The soap liquid is formed in the box and the old-fashioned soap making is completed.

Second, the soap-making ingredients commonly used by the ancients include: pig, cattle, sheep, animal and plant oils (fats), pancreas, wood ash, soybeans, alkali, soap beans, etc. The saponins and other ingredients contained in soapberries are natural surfactants. In other words, as long as you crush the soapberries, you can use them to wash clothes directly. Soy flour also contains saponins, and the pancreas contains enzymes. Putting the two together has a great cleansing effect.

What are the oldest ways to make homemade soap? Crush the pancreas. As mentioned earlier, the pancreas contains enzymes. Add animal fat and wood ash (containing alkali) or alkali to produce something called "fatty acid salt" in modern times. It is also a surfactant that can remove dirt. The soap made in this way is what the old saying goes "soap", and it has an excellent cleansing effect. The above formulas can also be mixed. If you want it to be aromatic, add spices. For example, if you like sandalwood, then go and get some sandalwood. It is okay to use modern flavors, but you will feel that they are not natural. But in fact, modern flavors are basically extracted from plants. Even the most high-end perfume in the universe is actually blended from essences.
