What are the Properties and Applications of Potassium Hydroxide?

Some qualities are required of the base for any cleaning product. For instance, it should be a potent chemical base, react favourably with oils and fats, have a high affinity for water, and be capable of degrading a wide range of substrates. Potassium hydroxide (KOH) possesses all of these features and more.


KOH solution is a clear, colourless, inorganic liquid that can be used as a powerful alkali base. Potassium hydroxide is a corrosive as well as a strong alkaline solid or powder that is white in colour and is also available in bulk with Palvi FZE - one of the most distinguished Potassium Hydroxide suppliers in UAE.


Due to its small molecular size, potassium hydroxide may swiftly enter oil molecules and separate them from surfaces. In addition to being corrosive, potassium hydroxide has the added benefits of being highly soluble in water, thermally stable, and reacting well with acids.


And because it's alkaline, it's a great grease remover because it creates an emulsion, a mixture that suspends oily or solid particles in wash water so they can be readily removed with rinsing. Potassium hydroxide's properties make it ideal for use in industrial-strength cleansers like those designed to unclog drains and disinfect ovens.




KOH is quite resistant to heat. Melt-casting into pellets or rods allows for a reduced surface area and efficient handling qualities due to the material's strong stability and comparatively low melting point. Due to the hygroscopic nature of KOH, these pellets become tacky when exposed to humidity. The remaining 10% or so is usually just water and carbonates in commercial samples. Strong exothermic reactions occur when it dissolves in water. Potassium lye is a common name for highly concentrated aqueous solutions. Solid KOH does not easily dehydrate, even when heated.




The OH group is functionally a spherical anion with a radius of 1.53 (between Cl and F in size) due to the quick or random disordering of the OH group. K+OH distances at an ambient temperature range from 2.69 to 3.15, on the basis of the orientation of the OH group, indicating that the environment around the K+ centres is distorted. KOH crystallises into a sequence of hydrates, from the monohydrate KOH · H2O to the dihydrate KOH · 2H2O to the tetrahydrate KOH · 4H2O.


Potassium Hydroxide as a Cleaning Agent:


Dissolving potassium hydroxide in water makes it usable as a cleaning agent, but only after it has been mixed with surfactants as well as other alkalinity sources. What you get is a liquid or solid that may be used to clean a wide range of surfaces, free of the most common pollutants. The solution's surface tension is decreased, allowing the contaminant to be separated from the surface and an emulsion to develop. It is simple to remove oil-water emulsions thanks to the surfactants, which have one end that dissolves in water (hydrophilic) and the other end that dissolves in oil (hydrophobic). Potassium Hydroxide can be used as a cleaning agent. If you are looking for a company that ranks high among the most trusted Potassium Hydroxide exporters in UAE, Palvi FZE is the most reliable name in the market.


It is significant to remember that on the basis of the surface being cleaned, the potassium hydroxide concentration should be adjusted. For instance, surfaces made of steel, cast iron, and stainless steel may withstand higher concentrations than would be suggested for surfaces made of relatively soft alloys like brass, copper, and aluminium.


Because of its distinctive qualities, potassium hydroxide is a versatile and effective cleaning solution that delivers unmatched results for a variety of cleaning applications. The top European cleaning product companies therefore frequently employ potassium hydroxide produced by Palvi FZE, assisting you in maintaining the best possible condition for your home.




Caustic potash is a common name for the chemical substance potassium hydroxide (KOH). The finished product is a white solid that can be purchased in pellets or flakes. It has similar properties to sodium hydroxide (NaOH), including being a strong alkali that is readily soluble in water and corrosive. Fuel cells, soaps, fertilisers, batteries, as well as biodiesel are just some of the products that can benefit from their utilisation.


Preparation of Salts:


Because of its high alkalinity, potassium hydroxide can be utilised to produce salts of potassium by reacting with acids. In turn, these salts can be used in a wide variety of contexts. Phosphates of potassium such as potassium carbonate are used in making soap and glass, potassium cyanide in electroplating as well as gold mining, and potassium permanganate as a disinfectant are just a few examples.


Neutralization of Acids:


Potassium hydroxide is used to raise the pH of liquids and neutralise acids because it is alkaline. It has great utility in titrating acid concentrations in chemical analyses. Potassium Hydroxide manufactured and supplied by an excellent as well as the most prominent Potassium Hydroxide distributor in UAE - Palvi FZE is used to neutralize the acids.


Production of Soaps:


Saponification refers to the process by which potassium hydroxide reacts with oils and fats at high temperatures. Soaps made from potassium are milder and more water-soluble than those made from sodium hydroxide, and this reaction is helpful in their manufacturing. Soaps that are used for washing dishes are typically made with sodium, whereas those used for washing hands are typically made with potassium.


Manufacturing Fuel Cells and Batteries:


Manganese Dioxide-Zinc, nickel-cadmium, as well as alkaline batteries, use an aqueous solution of potassium hydroxide as the electrolyte. Moreover, it serves as an electrolyte in some varieties of fuel cells. In terms of electrical conductivity, KOH solutions are favoured above sodium hydroxide solutions.


Miscellaneous Uses:


Extracting biodiesel from fats as well as oils uses potassium hydroxide as a catalyst. It aids in the process of making paper by removing lignin from the cellulose fibres. It is used as a bleaching agent in the textile industry as well as an etchant in the semiconductors’ wet processing. Sulphur trioxide (SO3), Carbon dioxide (CO2), as well as Nitrogen trioxide (NO3) are all gases that can be absorbed by this KOH. It can also be used to dissolve animal carcasses, remove hair from skins, and unclog drains. It could also be used to wash and chemically peel fruits and vegetables, as well as in the manufacturing of caramel colour and chocolate and cocoa.
