Lithium Stearate Powder
Lithium Stearate Properties:
Lithium stearate is a white powdered compound with the chemical formula LiC18H35O2.
Lithium stearate density: 1.025g /cm3.
Lithium stearate melting point: 220.0-221.5℃.
Stable at room temperature and pressure.
Lithium stearate solubility: slightly soluble in water, and ethanol, the water solubility is 0.09 g/ 100mL, and ethanol solubility is 0.04 g/100ml. Decomposition into stearic acid and corresponding lithium salts in response to strong acid. Insoluble in ethyl acetate and mineral oil. Colloids form in mineral oils. 

Lithium stearate is officially classified as soap (a salt of fatty acids). Lithium stearate is a white soft solid prepared by the reaction of lithium hydroxide with stearic acid.
Lithium stearate and lithium 12-hydroxy stearate are lithium soaps that are components of lithium grease and release agents.

How is Lithium Stearate made?

Method 1:  

10g stearic acid was dissolved in 100mL 95% ethanol, and titrated with 0.5mol/L lithium hydroxide ethanol solution (if lithium hydroxide could not be completely dissolved in ethanol, water could be added to make it completely dissolved). Phenolphthalein was used as an indicator. After the reaction reached the equivalence point, the precipitated lithium stearate soap was extracted and filtered out.  The crude product can be recrystallized with 95% ethanol to obtain pure product.  

Method 2:  

Sodium hydroxide is dissolved in water to form a solution, to which stearic acid is added, and then fully reacted and heated to more than 100℃. Dissolve lithium chloride in water, cool it to room temperature, and add it to the prepared sodium stearate solution for reaction;  After the reaction is finished, it is released and dehydrated by centrifuge. Using air drying equipment for drying, get the finished product. 

Lithium Stearate Applications:

Cosmetics and Skin Care: Lithium stearate is widely used in cosmetics and skin care products as a common emulsifier and emollient. It helps to improve the moisturizing and humectant effect of the products and forms a film on the skin surface, which helps to lock in moisture and keep the skin smooth and delicate.

Plastics Industry: Lithium Stearate is used as a plasticizer and stabilizer in the plastics industry, helping to improve the flexibility and durability of plastics. It also acts as a lubricant to minimize friction and wear during the plastic molding process.

Rubber industry: Lithium stearate is used as a vulcanizing agent and lubricant in the rubber industry. It increases the hardness and elasticity of rubber and helps to improve the processing properties of rubber. In addition, lithium stearate improves the anti-aging properties of rubber products and extends their service life.

Coatings and Paints: Lithium Stearate is used as a thickener and pigment dispersant in coatings and paints. It improves the viscosity and hiding power of coatings and helps the pigments to be evenly dispersed in the coatings. In addition, lithium stearate improves the weathering and water resistance of coatings, making them more durable.

Pharmaceutical field: lithium stearate also has some applications in the pharmaceutical field. It can be used as a drug carrier to help the drug penetrate better into the skin or mucous membranes and improve the efficacy of the drug. In addition, lithium stearate can also be used as a drug protection agent to reduce the irritation and side effects of drugs on the human body.

Agricultural field: lithium stearate can be used as fertilizer synergist and pesticide carrier in agricultural field. It can improve the utilization rate of fertilizers and promote the absorption of nutrients by plants, and also help pesticides better adhere to the surface of plants and improve the prevention and control effect of pesticides.

Petrochemical field: Lithium stearate can be used as a lubricant and additive in the petrochemical field to improve the quality and performance of petroleum products. In addition, lithium stearate can be used as a raw material for the production of flavors and fragrances.

Food industry: lithium stearate can be used as an emulsifier and stabilizer in the food industry to improve the taste and stability of food. For example, it can be used to make dairy products such as ice creams and cheeses to improve their texture and taste.

Surfactant: Lithium stearate can be used as a surfactant to help detergents and other laundry products better clean various surfaces. It has good detergency and penetration to effectively remove dirt and grease.

Environmental field: lithium stearate also has some applications in the environmental field. It can be used to prepare biodegradable plastics and reduce white pollution. In addition, lithium stearate can be used as a lubricant and fuel additive to reduce mechanical wear and energy consumption.
