Stearic acid is composed of carbon, hydrogen and oxygen atoms. The COOH-caustic agent, which produces the chemical property of this molecule, is at its bottom. The acidic group of stearic acid is involved in the oxidation and reduction reactions and creates new molecules. The most important reactions of stearic acid in the industry are the production of various metal stearates such as zinc stearates, calcium stearates, magnesium, potassium, etc.. These materials cover the most important industrial uses. The table below shows the physical and chemical properties of stearic acid.
The molecular structure of stearic acid is shown in the form.

Given that stearic acid has a hydrogen in its molecular structure, it is reactively reactive and is easily involved in ion-reactive reactions with another ion atom. For this reason, knowledge of the chemical safety of this substance is necessary for people who are associated with stearic acid.
For stearic acid, no toxic effects or acute effects have been observed, but people who are in contact with stearic acid powder or vapors and dust are irritating to the eyes, skin, and respiratory system. Contact with stearic acid also causes digestive system disorder.
If a person's skin come into contact with stearic acid, immediately rinse the contact area and in the event of excessive irritation and inflammation immediately see your doctor. In case of inhalation of vapors irritate the respiratory system and stearic acid, it is better to be moved to the open air and, if possible, he used oxygen to breathe better.
Stearic acid should be stored and stored away from heat sources, heat sources, fire and moisture. All packages containing Stearic Acid should have an industrial label including the weight, safety and physical properties of the substance. This material should be stored in closed containers and away from oxidizing and alkaline materials.
