High Quality Potassium Stearate CAS 593-29-3, 98%

Description of Potassium Stearate：

Potassium stearate has strong surface activity and can form micelles in aqueous solution, reducing the surface tension of water. In addition, it also has the effect of emulsification and dispersion and can be used as an emulsifier and dispersant. Potassium stearate has a strong emulsifying ability, can form a stable emulsion, and is widely used as an emulsifier and dispersant in the food, cosmetic, and pharmaceutical industries.

Potassium stearate also has antioxidant and antiseptic properties. It can form a stable complex with metal ions to prevent metal ions from reacting with other substances, thus playing a role in corrosion protection. In addition, potassium stearate can also be used as an antioxidant to prevent oxidation and deterioration of food, medicine, and other substances.

The water solubility and high-temperature resistance of potassium stearate are also good. It is easily soluble in water and will not decompose or deteriorate even under high-temperature conditions. Therefore, potassium stearate is widely used as an additive in food, pharmaceutical, cosmetic, and other industries, which can improve the stability, antioxidant, and taste of the substance.

In addition, potassium stearate also has a lubricating and softening effect. It can be used as a lubricant to reduce friction and wear. In plastics, rubber, coatings, and other fields, potassium stearate can be used as a plasticizer and softener to improve the toughness and softness of products.

It should be noted that potassium stearate has a certain irritation and should not be excessive use. If used in excess, it may cause an irritating reaction to the skin or eyes. Therefore, when using potassium stearate should pay attention to safety, control the amount, and use the method.

Applications of Potassium Stearate：

Food industry: Potassium stearate is mainly used as an emulsifier, stabilizer, and antioxidant in the food industry. It can improve the stability of food and prevent food oxidation and deterioration. For example, when making ice cream, ice cream, drinks, and other foods, adding potassium stearate can play an emulsifying and stabilizing role, preventing food stratification and precipitation. In addition, potassium stearate can also be used as a food additive to improve the antioxidant capacity of food.

Pharmaceutical industry: Potassium stearate has a variety of uses in the pharmaceutical industry. It can be used as a carrier and lubricant for drugs, increase the stability and solubility of drugs, and improve the efficacy and bioavailability of drugs. For example, when making drug capsules, tablets, suppositories, and other drugs, adding potassium stearate can play a role in lubrication and slow release, improving the efficacy and stability of drugs. In addition, potassium stearate can also be used as a medicinal excipient and has certain pharmacological effects.

Cosmetics Industry: Potassium stearate is widely used as an emulsifier, moisturizer, and antioxidant in the cosmetics industry. It can improve the texture and improve the antioxidant capacity of cosmetics. For example, when making cosmetics such as skin care products, shampoos, and body washes, adding potassium stearate can play an emulsifying and moisturizing role. In addition, potassium stearate can also be used as a cosmetic raw material, such as the preparation of fat-soluble vitamins.

Commodity industry: Potassium stearate is also widely used in the commodity industry. For example, in the production of detergent, laundry detergent, hand sanitizer, and other daily necessities, adding potassium stearate can increase the moisture and moisturizing effect of the product while improving the antioxidant capacity of the product. In addition, potassium stearate can also be used as a softener in leather processing to improve the softness and comfort of leather.

Industrial field: Potassium stearate is also widely used in the industrial field. For example, it can be used as an emulsifier in the petroleum industry to help with oil extraction and processing. In addition, potassium stearate can also be used as a metal cleaning agent, pesticide dispersant, and so on.

Plastics and rubber industry: Potassium stearate is widely used as a plasticizer and softener in the plastics and rubber industry. It can improve the toughness and softness of the product and improve the processing performance and service performance of the product. In addition, potassium stearate can also be used as an antioxidant for plastics and rubber, improving the antioxidant properties of products.

Production Method of Potassium Stearate：

Potassium hydroxide and stearic acid reaction: stearic acid and potassium hydroxide in accordance with a certain proportion of the mixture, reaction at a certain temperature for a certain time, after the end of the reaction through cooling, crystallization, filtration, drying, and other steps to obtain potassium stearate products. The advantage of this method is that the process is simple and easy to operate. Still, a certain amount of wastewater and waste gas will be generated during the reaction process, which needs to be treated.

Direct saponification method: stearic acid and potassium hydroxide are mixed according to a certain proportion, without separation and washing, directly heated and stirred, and potassium stearate solution is obtained after the reaction. The product quality is not stable enough, and it needs to be processed later to get high-quality potassium stearate products.

Transesterification method: the stearate and sodium methanol or sodium ethanol and other alkaline substances are mixed reaction at a certain temperature for a certain time after the end of the reaction through separation, washing, drying, and other steps to obtain potassium stearate products. The advantages of this method are fewer by-products, but it requires the use of organic solvents such as methanol or ethanol, which have a certain impact on the environment.

Enzyme catalysis: The use of enzyme catalysis of stearic acid and potassium hydroxide reaction to obtain potassium stearate. The advantage of this method is high selectivity, but it requires the use of enzyme preparations and has a high cost.
