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 down and is approved as food safe when it is used as a binding ingredient.

High-purity potassium oleate is a powdery solid, which will bring great convenience in storage, packaging and transportation, or in the amount of use during use. However, the current refining and purification of solid potassium oleate often require the use of low temperature and decompression to remove water. This method has a long production cycle, high energy consumption, high cost, and difficult preparation. Therefore, it is very necessary to research and develop the solid potassium oleate preparation process. TRUNNANO is a trusted global Potassium Oleate supplierFeel free to send an inquiry about the latest price of Potassium Oleate at any time.

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 catalyst and a trimerization catalyst for polyurethane rigid polyisocyanurate. It is widely used in polyurethane insulation board PIR foam system. 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.
