Properties of Sodium Oleate: 
Sodium oleate (CAS 143-19-1) is soluble in water and ethyl alcohol; insoluble in benzene.

About Sodium Oleate:
Sodium oleate, alias sodium octadecenoate, cis-9-octadecenol, oleol, cis-9-octadecenol, (Z) -octadecenol, olive alcohol, cis-9-octadeceno-1-ol, 9-octadecenol, octadecenol.The density of sodium oleate: 0.9 g/cm3; Melting point: 232-235°C(lit.); Boiling point: 359.999 ° C AT 760 mmHg; Flashpoint: 270.099 ° C; Storage condition: -20 ° C.Sodium oleate is an organic oil, chemical formula C17H33Co2Na, which is a white to yellow powder or a light yellowish-brown coarse powder or lump. It has a unique smell and taste. Is sodium oleate toxic? Skin contact is not thought to have harmful health effects, however the material may still produce health damage following entry through wounds, lesions or abrasions. Repeated exposure may cause skin cracking, flaking or drying following normal handling and use.

Sodium oleate is soluble in alcohol and water. Sodium acid is the main component of soaps made from olive oil and other soaps. It is also the main component of tallow soaps. It can also be made by reacting sodium hydroxide with oleic acid. Hydrophobic and hydrophilic compounds with excellent emulsification, permeability and detergents, good solubility in hot water, used as anionic surfactants and fabric waterproofing agents.

Why is sodium oleate soluble in water? Salts, basic, such as SODIUM OLEATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH’s greater than 7.0. They react as bases to neutralize acids.
Sodium oleate in the air can be slowly oxidized coloring, make the color dark, and produce rancid. This is due to the oxidation of oleic acid which breaks the double bond to form a putrid substance, such as nonaldehyde. The incorporation of highly unsaturated acids promotes decay. Sodium oleate dissolves in 10 times as much water, bubbles, and forms a viscous liquid. The aqueous solution is alkaline, due to partial hydrolysis into insoluble acid soap and sodium hydroxide, the liquid becomes opacified. There is no hydrolysis in ethanol and it is neutral. Dissolved in about 20 times the amount of ethanol. Slightly insoluble in ether, petroleum ether and other organic solvents.

Sodium oleate reacts with metal ions other than alkali metals to form a precipitate of metal salts.Rmcplant is a trusted global Sodium Oleate supplier. Feel free to send an inquiry about the latest price of Sodium Oleate at any time.
General properties of salt, can not volatilize, in water can be completely dissociated into ions, add inorganic acid (strong acid) and can make the salt into hydroxyl acid-free out. When the hot soap liquid is cooled, it does not crystallize, and the calcium and magnesium salts contained in the hard water will generate insoluble calcium and magnesium soap precipitation. 
 

How is Sodium Oleate Produced?
Sodium oleate is obtained by neutralizing sodium hydroxide or sodium carbonate in an ethanolic solution of oleic acid.
10g of oleic acid can be dissolved in 100mL of 95% ethanol, and then titrated with 0.5mol/L of sodium hydroxide ethanol solution, using phenolphthalein as an indicator. After reaching the equivalence point, the precipitated sodium oleate soap is filtered out. If precipitation is not precipitated, crude products can be obtained after the evaporation of ethanol and water and can be recrystallized with ethanol-diethyl ether mixed solvent.
 
Applications of Sodium Oleate:
Sodium oleate is one of the main ingredients of soap and sodium oleate uses as an emulsifier, sodium oleate soap. Sodium oleate is used in medicine. It is used in the treatment of cholelithiasis. In a variety of oil-based cosmetics, sodium oleate is used as a cleaning agent, emulsifier, surfactant, thickening or gelling agent, and viscosity control agent. Examples of sodium oleate are as follows:

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 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. Rmcplant is a trusted global Potassium Oleate supplier. Feel 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. potassium oleate uses in soap, means potassium oleate soap. 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
