Potassium hydroxide 90%

Potassium Hydroxide 90% – High-Purity Caustic Alkali for Industrial Applications

Potassium Hydroxide 90%—a name that might not mean much to most people, but to those in the industrial world, it’s a workhorse. This solid, highly concentrated form of caustic potash shows up in everything from biodiesel facilities to soap factories. Here in Perth, we’re proud to be among the trusted chemical suppliers offering it in solid flakes or pellets, ready for the most demanding jobs where minimal water and maximum punch are essential.

So… What Exactly *Is* Potassium Hydroxide 90%?

In simple terms? It’s a strong, no-nonsense inorganic base. Chemically known as KOH—or caustic potash if you’re feeling old-school—it carries potent alkaline properties. The 90% concentration refers to how pure it is in solid form, making it perfect for dry environments where adding water would throw things off balance.

It usually comes as crisp white flakes or small pellets. Easily soluble in water (and even in ethanol), it’s frequently used in pH regulation and chemical synthesis. You’ll find it quietly doing its job behind the scenes in many industries that most folks never think about.

Where Is Potassium Hydroxide 90% Used?

Now, this is where it gets interesting—because its applications are pretty diverse. Here are a few key ones:

• Soap & Detergent Manufacturing – It plays a starring role in the saponification process, especially for liquid and soft soaps. Without it, your soap might not even be soap.
• Biodiesel Production – It’s a catalyst in transesterification. (That’s a fancy way of saying it helps convert fats and oils into biodiesel.)
• Battery Electrolytes – It’s used in alkaline batteries for its excellent conductivity. Pretty important stuff when you need reliable power.
• Fertiliser Blends – Supplies slow-release potassium or water-soluble nutrients for agriculture. Quietly feeding your food, in a way.
• Laboratory & Pharmaceutical Applications – Often used to control pH, neutralise acids, and act as a reactive agent in various chemical reactions.

What makes it especially appealing is its consistency. Whether it’s batch production or a continuous industrial line, Potassium Hydroxide 90% tends to behave exactly how you’d expect. That’s a trait people wish more coworkers had, honestly.

Packaging, Safety & Documentation

• CAS Number: 1310-58-3
• Appearance: White solid (flakes or pellets)
• Odour: Odourless
• Solubility: Highly soluble in water
• pH (1% solution): 13.5–14.0 (strongly alkaline)

Handling Safety: Now, here’s where things get serious—don’t treat this stuff casually. Gloves, goggles, proper PPE—absolutely essential. Avoid any contact with skin or eyes. And always—always—add KOH to water, not the other way around. Pouring water on it first can trigger a sudden, intense heat reaction. Not quite “explosive,” but definitely not pleasant.

Storage Guidelines: Keep it cool, dry, and away from moisture or acids. Make sure containers are sealed tightly.
