Potassium Hydroxide Solution 45%, 49%

Potassium Hydroxide Solution – Versatile Grades for Industrial Use

Potassium Hydroxide Solution is one of those chemicals that seems to quietly power so many industries behind the scenes. Available in two main concentrations—45% and 49%—this clear, odourless alkaline liquid plays a surprisingly central role in everything from food processing to pH control, biodiesel manufacturing, and more.

Now, if you’re looking around for chemical suppliers in Perth who actually stock these grades with proper documentation and local access, you’ve landed in the right place. Our potassium hydroxide solutions are formulated for consistency and reliability—and yes, they’re in stock.

🔍 What Is Potassium Hydroxide?

Potassium hydroxide—KOH if you’re into abbreviations, or caustic potash if you’re feeling old school—is a strong base that dissolves easily in water and gives off heat while doing so. That’s part of what makes it useful, but also something to respect during handling.

It’s a key reagent in industrial chemistry: think saponification, pH neutralisation, or deacidifying certain processes. Some folks even choose it over sodium hydroxide because of its higher solubility and reactivity in specific contexts. Whether that’s *actually* always better depends on the job, but it’s often the preferred option in sensitive formulations.

📊 Available Concentration Grades

🧪 Potassium Hydroxide 45% Solution

The 45% grade is sort of the sweet spot—strong enough to perform but easier to handle than the ultra-concentrated stuff. You’ll find it used in cleaning chemicals, agricultural mixes, and water treatment systems. It offers good alkalinity without being, well, intimidating. Some manufacturers like it precisely because it keeps things safer without sacrificing performance.

🧪 Potassium Hydroxide 49% Solution

Then there’s the 49%—more concentrated, more potent, and frankly, a bit more demanding. This grade is perfect for high-performance applications like electroplating, transesterification in biodiesel production, and industrial degreasing. You’ll also see it in some chemical manufacturing lines and pH control processes, particularly where precision matters.

🏭 Industrial Applications & Benefits

Both concentration grades are used extensively across Australian industries. Here’s a quick breakdown of how they help:

• pH regulation in water treatment and chemical processing plants
• Saponification in soft soap and detergent manufacturing
• Electrolyte base in battery production and electroplating
• Food-grade deacidification (where regulations allow)
• Transesterification agent for biodiesel

They’re colourless, odourless, non-volatile, and pretty straightforward to transport. And while they’re not exactly glamorous, their dependability makes them essential.
