Stearic Acid in Soap

On stearic acid in soap
Soap is also a daily thing. Its production involves many chemical principles, and stearic acid is an important part of it.

Stearic acid is the key ingredient of soap. Its mild nature plays a great role in the formation and efficacy of soap. When making soap, the oil undergoes a saponification reaction, and stearic acid stands out. Oil and alkali blend, just like yin and yang. After complicated changes, stearic acid becomes the backbone of soap.

Looking at the texture of soap, the power of stearic acid is fully demonstrated. Appropriate stearic acid can make the soap body solid, not easy to be soft and rotten, and easy to hold and use. And it can adjust the solubility of the soap, slowly dissolve in water, and exert the cleaning effect. If the content of stearic acid is inappropriate, the soap will be too soft if it is not too hard, which will damage its use.

When talking about the cleaning power of soap, stearic acid is also the most powerful. Its molecular structure is unique, one end is lipophilic and the other end is hydrophilic. In case of oil stains, the lipophilic end is tightly attached to the oil stains, while the hydrophilic end is close to the water. In this way, after rubbing and stirring, the oil stains will be wrapped in the stearic acid molecules and go away with the water to achieve the purpose of cleaning.

And the preservation of stearic acid in soap is also beneficial. It can slow down the oxidation and rancidity of soap, prolong the shelf life of soap, and make soap last for a long time without losing its effectiveness.

However, when making soap, the amount of stearic acid needs to be precisely controlled. If there is too much soap, it will be too alkaline and hurt the skin; if there is too little, it will not be enough to clean and it will be difficult to remove dirt. Therefore, those who are good at making soap must carefully observe the characteristics of stearic acid and weigh its dosage in order to achieve the perfection of soap.

In general, stearic acid is indispensable to soap, just like beams and pillars are indispensable to buildings. Knowing its properties and making good use of its capabilities, you can get the best soap for the benefit of people's livelihood and daily use.
