The Most Versatile Raw Chemical in Our Lineup

potassium hydroxide banner

Potassium hydroxide (KOH), also known as caustic potash or potash lye, is a powerful, odorless, colorless base chemical. Sold in flake form for easy application, potassium hydroxide is produced by evaporating the water from liquid potassium hydroxide (LKOH). It also produces a significant amount of heat when dissolved in water.

It is useful for literally hundreds of applications, including the manufacture of soaps, biodiesel, batteries, fuel cells, beauty supplies, cleaners and fertilizers. This product needs to be mixed carefully with the proper ingredients by a professional who understands how serious the effects of this chemical can be.

Factory Direct Chemicals' Pure Potassium Hydroxide Flakes are sold in a simple, convenient bottle with a child-proof cap.

  • Potassium Hydroxide is water soluble, making it preferable for the environment
  • An improtant chemical compound for the agricultural industry, potassium hydroxide is often used to regulate pH in acidic soil
  • The reaction of potassium hydroxide with oils and fats in heat is called saponification, making it useful for creating soft soaps.
  • Can help improve drilling and well efficiency as well as the refining process.
  • Extremely versatile cleaning agent found in denture cleaners, oven cleaners, driveway and concrete cleaners, oven cleaners and more.


Create Soft Liquid Soaps

liquid soap making

The reaction of potassium hydroxide with oils and fats under heat is called saponification. This reaction is useful in creating softer and more soluble soaps than sodium hydroxide and is better for the environment. Liquid soaps tend to be potassium soaps and also referred to as “soft soaps”, while solid soaps tend to be sodium soaps. You can also use it in conjunction with sodium hydroxide to create shaving products.


oil and gas purificationOil and Gas Industry

Potassium Hydroxide can help improve drilling and well efficiency as well as the refining process. When drilling hard, sensitive shales such as clay, potassium ions attach to the clays surface minimizing dispersion of the cuttings into finer particles. It also increases the muds pH helping to make lignite soluble and easy to remove. Once oil and gas are recovered, potassium hydroxide is used in the refining process to remove contaminants like unwanted organic acids and sulfur compounds from raw petroleum. Removing impurities like this is known as sweetening.

ph regulator

pH Regulator

It is also a strong alkali, or base and is beneficial as a pH regulator in industrial manufacturing and processing. In the agricultural industry, it’s used to regulate the pH of acidic soils. Due to it’s low salt index and high solubility, caustic potash also serves in the manufacture of liquid fertilizer mixtures. The liquid is known to increase crop yield and improve the drought tolerance of crops.


Potassium Hydroxide is employed as the electrolyte in alkaline batteries. Potassium Hydroxide is preferred over sodium hydroxide because its solutions are more conductive, has more compatibility with various electrodes and has a low freezing point temperature. Usually batteries with KOH give off a high performance and have a long cycle life.

oven cleaning


Potassium Hydroxide is an extremely versatile cleaning agent. You can find it in varied items such as denture cleaners, oven cleaners, drain cleaners, driveway and concrete cleaners, and pipe cleaners. As a strong base, it reacts with grease and fats, making it a useful ingredient in drain and oven cleaners.

Other Common Uses

Pure Potassium Hydroxide Flakes are used in many industrial, manufacturing, and chemical processes, including:

  • Industrial soap and hairspray applications
  • Glass production
  • Dyestuffs
  • Cosmetic Industry
  • Deicer for airports
