POTASSIUM HYDROXIDE 90%: A POWERFUL BASE IN INDUSTRIAL AND LABORATORY APPLICATIONS

Potassium Hydroxide 90%, commonly referred to as caustic potash, is one of the most widely used alkaline compounds in chemical manufacturing and laboratory applications. With a purity level of 90%, this grade of KOH is designed for high-performance industrial operations where a potent yet economically viable alkali is required.

Whether used in soap production, biodiesel processing, pH control, or chemical synthesis, Potassium Hydroxide 90% remains a cornerstone in both traditional and modern industries.

🧪 What is Potassium Hydroxide 90%?

Potassium Hydroxide (KOH) is a strong base that is highly soluble in water and alcohol. The 90% grade refers to its composition—90% pure KOH, with the remaining 10% typically comprising water and trace impurities. This form is often sold as white flakes or pellets, known for their hygroscopic and corrosive nature.

Its powerful alkaline properties make it comparable to sodium hydroxide (NaOH) but with key differences in solubility, reactivity, and compatibility in various chemical processes.

🔍 Core Applications of Potassium Hydroxide 90%

1. Soap and Detergent Manufacturing

One of the most traditional uses of Potassium Hydroxide is in the saponification process, where it reacts with fats and oils to create potassium-based soaps. These soaps are:

• Softer and more water-soluble than sodium-based soaps
  
• Preferred for liquid soap formulations
  
• Used in cosmetics, industrial cleaners, and handwashes
  

2. Biodiesel Production

KOH 90% is a preferred catalyst in biodiesel synthesis, especially in the transesterification process. It facilitates the reaction between vegetable oils or animal fats and methanol, resulting in fatty acid methyl esters (FAMEs) — the primary component of biodiesel.

3. Chemical Manufacturing

As a key reagent, Potassium Hydroxide is used in:

• Potassium salt production (e.g., potassium carbonate, potassium phosphate)
  
• Neutralizing acids in various reactions
  
• pH adjustment in chemical processes
  

Its strength and solubility make it ideal for strongly alkaline environments, especially when sodium contamination must be avoided.

4. Battery Electrolytes and Electronics

KOH is used in alkaline battery production as an electrolyte due to its excellent ionic conductivity. It plays a role in high-performance batteries and certain electroplating or surface treatment procedures.

5. Agriculture and Fertilizer Use

In controlled settings, Potassium Hydroxide contributes to:

• Production of potassium-based fertilizers
  
• Soil pH correction
  
• Hydroponic nutrient solutions
  

⚙️ Chemical and Physical Properties

• Chemical Formula: KOH
  
• Appearance: White flakes or pellets
  
• Purity: 90% minimum
  
• Molecular Weight: 56.11 g/mol
  
• pH (1% solution): ~13.5
  
• Solubility: Fully soluble in water and alcohol; exothermic reaction with water
  
• Corrosiveness: Highly corrosive to skin and metals
  

Due to its hygroscopic nature, KOH absorbs moisture and carbon dioxide from the air, forming potassium carbonate on exposure.

🧯 Handling and Storage Guidelines

Because of its reactive and corrosive properties, proper handling is crucial:

• Wear full PPE: gloves, eye protection, lab coat or apron
  
• Store in a tightly sealed, non-metallic container
  
• Avoid exposure to moisture and acids
  
• Use in well-ventilated environments or fume hoods
  

When dissolving in water, always add KOH slowly to water (never the reverse) to avoid splashing from the intense exothermic reaction.

✅ Why Choose Potassium Hydroxide 90%?

The 90% purity strikes an ideal balance between performance and cost-efficiency, especially for:

• Bulk industrial processes
  
• Formulation of consumer goods
  
• Intermediate synthesis in chemical plants
  

It provides strong alkalinity while minimizing unnecessary cost tied to ultra-high purity levels when not required. This makes it highly effective in commercial settings where consistent performance is necessary, but analytical-grade material is not essential.
