About Potassium Stearate:
Potassium Stearate is a white crystalline powder. Easily soluble in hot water, insoluble in ether, chloroform and carbon disulfide. Its aqueous solution has strong alkalinity to litmus or phenolphthalein, and its ethanol solution has weak Alka.
What we usually call soap in our lives is a mixture of fatty acid sodium obtained by saponification of various fats and oils with sodium hydroxide. These fatty acid sodium are actually a comprehensive term for sodium stearate, sodium palmitate, sodium oleate, sodium linoleate and other fatty acid sodium.
Potassium Stearate CAS 593-29-3
If you do not use mixed oils in saponification, but only use a single stearic acid and sodium hydroxide (commonly known as caustic soda, caustic soda), you get sodium stearate soap; if you use stearic acid and potassium hydroxide for saponification, The result is potassium stearate soap.
Compared with sodium soap, potassium soap has higher solubility and transparency, and less irritation. Feel free to send an inquiry to get the latest price if you would like to buy Potassium Stearate in bulk.

How is Potassium Stearate produced?
Potassium Stearate is the potassium salt of the fatty acid of stearic acid. It is derived from the saponification of vegetable oils. Potassium Stearate is derived from Stearic Acid—a byproduct of vegetable oil through the saponification process. Potassium Stearate is primarily used as a cleansing agent and emulsifier.
Applications of Potassium Stearate:
Potassium stearate can be used as a cleanser for hair, face and body, as well as a co-emulsifier for skincare products, cosmetics and hair styling products. At the same time, it has a good cleaning effect and can make the skin fresh and clean.
Potassium stearate is mainly used in cosmetics and skincare products as surfactants, cleansers, and emulsifiers. It has a risk factor of 1. It is relatively safe and can be used with confidence. Generally, it has no effect on pregnant women. Potassium stearate is not acne-causing.
Potassium stearate is mainly used as a cleaning agent and emulsifier. It can be used in much personal care and cosmetic applications. It can also be used in certain rubber manufacturing and as a basis for textile softeners
Application of Potassium Stearate in the Rubber Industry:
In the rubber industry, potassium stearate is mainly used as a rubber vulcanizing agent and vulcanizing accelerator. Its mechanism of action is the introduction of active groups, such as sulfur atoms, into rubber, which can undergo cross-linking reactions with rubber molecules during heating, improving the hardness and wear resistance of the rubber. In addition, potassium stearate can also improve the processing properties of rubber, such as plasticity and flowability. In the production process of rubber products, adding a certain amount of potassium stearate can effectively improve the quality and stability of rubber products.
The Application of Potassium Stearate in Cosmetics:
In cosmetics, potassium stearate is mainly used as a moisturizer, softener, and emulsifier. Its mechanism of action is to form a protective film by combining with the oil on the skin surface, locking in skin moisture, maintaining skin moisture balance, and keeping the skin soft and smooth. In addition, potassium stearate can also be used as an emulsifier to prepare various creams and lotions to improve cosmetics' stability and moisturizing effect. Cosmetics using potassium stearate are mild, nonirritating, and easy to absorb, making them suitable for use by people of various skin types.
The Application of Potassium Stearate in the Coatings Industry:
Potassium stearate is mainly used as a water-resistant agent and lubricant in the paint industry. Its mechanism of action is to improve the water-resistance and lubricity of the coating, thereby improving the coating performance and service life. In addition, potassium stearate can also improve the glossiness and transparency of coatings, making them more aesthetically pleasing. Adding potassium stearate to coatings can effectively improve their adhesion and uniformity while reducing their irritation and pollution and improving their safety and environmental friendliness.

FAQs of Potassium Stearate CAS 593-29-3
Q: What is potassium stearate used for?
A: Potassium stearate, with the CAS number 593-29-3, finds extensive use across various industries due to its versatile properties. In the cosmetics and personal care sector, it serves as an emulsifier, thickener, and opacifying agent in products like creams, lotions, and soaps, helping to stabilize formulations and enhance texture. Within the food industry, potassium stearate acts as a food additive for its emulsifying capabilities, contributing to the consistency and shelf life of baked goods, confectionery, and dairy products. Additionally, this compound is utilized in the production of lubricants and greases, where it provides excellent water resistance and anti-corrosion properties. It also plays a role in the manufacturing of pharmaceuticals, aiding in tablet formation by improving flowability and compressibility of powders.
Q: Is potassium stearate safe for humans?
A: Potassium stearate is generally recognized as safe (GRAS) for use in both food and cosmetic applications when employed within recommended concentration limits and following good manufacturing practices. Extensive studies have shown that this compound has low toxicity and does not cause significant irritation or sensitization when applied topically or ingested within typical usage levels. However, during handling, precautions should be taken to avoid inhalation of dust particles and contact with eyes. The use of appropriate personal protective equipment (PPE), including gloves, safety glasses, and respiratory protection, can ensure safe handling. For specific applications, especially those involving ingestion or prolonged skin contact, consulting relevant safety data sheets and regulatory guidelines is advisable.
Q: What is the chemical composition of potassium stearate?
A: Potassium stearate is a metal soap formed through the reaction between potassium hydroxide (KOH) and stearic acid. Chemically, it consists of potassium ions (K⁺) and stearate ions, which are long-chain fatty acids typically composed of eighteen carbon atoms. This combination results in a material that exhibits amphiphilic properties, meaning it possesses both hydrophilic (water-attracting) and hydrophobic (water-repelling) characteristics. These properties make potassium stearate effective as an emulsifier, capable of stabilizing mixtures of oil and water, and as a surfactant, lowering the surface tension between substances. The precise ratio of components may vary depending on the manufacturing process and intended application, allowing for customization of physical and chemical properties to meet specific requirements.
Q: How does potassium stearate perform in skincare products?
A: Potassium stearate performs effectively in skincare products, offering multiple benefits. As an emulsifier, it helps create stable formulations by keeping oil and water phases from separating, ensuring product consistency over time. Its thickening ability contributes to the desirable texture of creams and lotions, providing a smooth and luxurious feel upon application. Moreover, potassium stearate can impart opacity to formulations, enhancing the coverage and hiding power of makeup products. It also assists in controlling shine by absorbing excess sebum, making it suitable for use in matte-finish cosmetics. Importantly, potassium stearate is non-toxic, non-irritating, and non-sensitizing, aligning well with the safety standards expected in skincare formulations.
