Product name: Potassium Oleate
CAS NO. 143-18-0
About Potassium Oleate:
Potassium oleate, another name is Potassium cis-9-octadecenoate. The chemical formula is C18H33KO2. Potassium oleate is a brown solid or a transparent amber liquid. It is fatty acid potassium found in natural soaps.
Potassium Oleate is a liquid potassium soap solution in water. Potassium Oleate is used as an emulsifier in many liquid soaps, facial cleansers, mustache waxes, body washes, and hair permanents. Emulsifiers act like surfactants and reduce the surface tension of a liquid.
Potassium Oleate is a natural constituent of vegetable oils like sunflower oil. It is used in soapmaking to make vegetable glycerin soaps. In its pure form, it can be an irritant; however, in soap making, it is reduced and approved as food-safe when used as a binding ingredient.
High-purity potassium oleate is a powdery solid, which will bring great convenience in storage, packaging, transportation, or the amount of use during use. However, the current refining and purification of solid potassium oleate often require low temperatures and decompression to remove water. This method has a long production cycle, high energy consumption, high cost, and difficult preparation. Therefore, it is necessary to research and develop the solid potassium oleate preparation process. TRUNNANO is a trusted global Potassium Oleate supplier.

How is Potassium Oleate produced?
A preparation method of solid powdered potassium oleate, the specific steps are:
1) The paste oleic acid and potassium hydroxide are reacted in the water phase to prepare a potassium oleate solution with a mass content of 10%-20%, and the mass content is 40% by the concentration at 70-80℃ -60% Potassium oleate in flowable viscous form;
2) After mixing the urea with the alcohol solution, stir at 70-90°C and form a hot saturated urea-alcohol solution after the area is completely dissolved;
3) Add the viscous potassium oleate to the urea-alcohol solution under the heat preservation state, stir thoroughly to form a uniform and transparent solution, keep stirring, cool the solution to -5-0℃, keep the low temperature for 1-3h to make the potassium oleate solid precipitate, Filter the precipitated hard potassium oleate powder (filter with gauze), and dry the solid with dry cold air to obtain the finished solid powdered potassium oleate.
Application of Potassium Oleate:
Potassium oleate is a potassium and trimerization catalyst for polyurethane rigid polyisocyanurate. It is widely used in polyurethane insulation board PIR foam systems. In addition, potassium oleate is also widely used in rubber emulsifiers, foaming agents, release agents, detergents, lubricants, fiber softeners, and surfactants. Potassium Oleate is used as an emulsifier in many liquid soaps, facial cleansers, mustache waxes, body washes, and hair permanents. Emulsifiers act like surfactants and reduce the surface tension of a liquid. Potassium Oleate prevents the ingredients in these products from separating into separate chemicals.
In addition, potassium oleate can also
Preparation of an antifungal agent for paint;
Preparation of multifunctional microemulsified gasoline and Oil combustion accelerator;
Preparation of anionic viscoelastic surfactant-based gel.

FAQs of Potassium Oleate CAS 143-18-0
Q: What is potassium oleate used for?
A: Potassium oleate, identified by the CAS number 143-18-0, serves a variety of functions across different industries due to its unique properties. In cosmetics and personal care products, it acts as an emulsifier, surfactant, and opacifying agent, contributing to the texture and stability of formulations such as soaps, shampoos, and lotions. Within the food industry, potassium oleate can be utilized as a food additive for its emulsifying capabilities, enhancing the consistency and shelf life of various products. Additionally, this compound finds use in the production of lubricants and greases, where it provides excellent water resistance and anti-corrosion properties. It also plays a role in pharmaceutical manufacturing, aiding in tablet formation by improving flowability and compressibility of powders. Moreover, potassium oleate can be found in industrial applications like metal cleaning and as a component in detergents and cleaners.
Q: Is potassium oleate safe for humans?
A: Potassium oleate is generally recognized as safe (GRAS) for use in both food and cosmetic applications when used within recommended concentration limits and following good manufacturing practices. 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. 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 oleate?
A: Potassium oleate is a metal soap derived from the reaction between potassium hydroxide (KOH) and oleic acid, a monounsaturated omega-9 fatty acid. Chemically, it consists of potassium ions (K⁺) and oleate ions, which are long-chain fatty acids typically composed of eighteen carbon atoms with a single double bond. 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 oleate 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 oleate perform in skincare products?
A: Potassium oleate performs admirably in skincare products, offering several benefits. As an emulsifier, it helps create stable formulations by keeping oil and water phases from separating, ensuring product consistency over time. Its surfactant properties contribute to the cleansing ability of soaps and cleansers, effectively removing dirt and oils from the skin without causing excessive dryness. Moreover, potassium oleate 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 oleate is non-toxic, non-irritating, and non-sensitizing, aligning well with the safety standards expected in skincare formulations.
