What is Calcium Stearate?
Calcium stearate is an organic calcium salt with the chemical formula C36H70CaO2 and molecular weight 575.5. Its structure mainly comprises stearate (C18H37COO-) and calcium ions (Ca2+). 
Calcium stearate is a white powder that is insoluble in water but in hot water and organic solvents. Its relative density is 1.08, and its melting point is between 140 and 150 ° C. Its molecular structure contains long chain fatty acid roots, so it has good emulsification performance. 
Calcium stearate also has good chemical stability. Composing under strong acid and base conditions is difficult, but hydrolysis reactions may occur under acidic conditions. Because the fatty acid roots in its molecular structure have good antioxidant properties, calcium stearate can also resist oxidative degradation in the air. 
In addition, calcium stearate also has good pharmacological properties. Studies have shown calcium stearate can inhibit gastric acid secretion and protect gastric mucosa. At the same time, it can also promote calcium absorption and has the effect of treating and preventing calcium deficiency. 
Calcium stearate has excellent performance as an emulsifier, dispersant, wetting agent, and so on. It has a good emulsification effect and stability and can improve the stability and quality. 
Application of Calcium Stearate
Cosmetics field 
Calcium stearate is mainly used as an emulsifier and dispersant in cosmetics, which can effectively improve product stability and emulsification effect. In addition, it can also be used as a moisturizer and antioxidant, which can improve the product's moisturizing effect and antioxidant properties. In cosmetics, calcium stearate is mainly used in creams, lotions, shampoos, and other products to regulate oil, moisturize skin, soften hair, and so on. 
Food field 
In the food field, calcium stearate can be used as an additive to make cookies, bread, candy, and other foods to improve the taste and freshness of products. In addition, calcium stearate can also be used as a nutritional booster to increase the nutrients in food, such as the content of calcium, to meet the needs of the human body for calcium. 
Medical field 
In medicine, calcium stearate can be used as a drug carrier to help the body better absorb drugs. At the same time, calcium stearate also inhibits gastric acid secretion, protects gastric mucosa, and can be used to treat digestive system diseases. In addition, calcium stearate can also be used as a drug additive to improve the efficacy and stability of drugs.

Production Method of Calcium Stearate
Saponification reaction 
First, the oil must be saponified with calcium hydroxide or calcium carbonate. Specifically, the oil is heated to a certain temperature, calcium hydroxide or calcium carbonate is added, and then heated and stirred for a certain time to make it saponification. In this process, calcium oleate or sodium stearate is produced, along with a large amount of glycerol and water. 
Abstersion 
The reaction liquid must be washed several times to wash away the glycerin and water in the oil. Add water, stir well, and then let it sit for some time in the washing process. After that, the supernatant is poured away, and new water is added for washing. This process is repeated several times until the glycerin and water in the reaction solution are sufficiently washed away. 
Precipitate 
Calcium oleate or sodium stearate needs to be precipitated to obtain a solid product of calcium stearate. Specifically, a precipitating agent (such as calcium chloride or calcium nitrate solution) needs to be added to the washed solution to undergo a double decomposition reaction with calcium oleate or sodium stearate to produce calcium stearate precipitation. 
Separation and drying 
The precipitated calcium stearate is separated and dried. Specifically, the sediment is filtered and washed several times in hot water to remove the remaining impurities. After that, the cake is dried in the oven to obtain a dried calcium stearate product.

Production Method of Calcium Stearate
Cosmetics field 
Calcium stearate is an emulsifier, dispersant, moisturizer, and antioxidant in cosmetics and can be widely used in creams, lotions, shampoos, and other cosmetics. With the improvement of people's consumption level and the enhancement of cosmetic safety awareness, consumers' demand for high-end, safe, and environmentally friendly cosmetics is increasing. Therefore, calcium stearate has a good market prospect in cosmetics. 
Food field 
In the food field, calcium stearate can be used as an additive in the production of biscuits, bread, candy, and other foods to improve the taste and freshness of products. With the increasing concern about food health and safety, food additives are increasingly restricted. However, as calcium stearate is a natural, safe, and healthy food additive, its market prospects are still relatively broad. 
Medical field 
In medicine, calcium stearate can be used as a drug carrier to help the body better absorb drugs. At the same time, calcium stearate also inhibits gastric acid secretion, protects gastric mucosa, and can be used to treat digestive system diseases.  
Other fields 
In addition to the above areas, calcium stearate can be applied to plastics, rubber, coatings, and other fields as a plasticizer, softener, gelling agent, etc. At the same time, calcium stearate can also be used in the preparation of nanomaterials, biomedical materials, and other fields. The development of these areas will also drive the continuous expansion of the calcium stearate market.
