Looking for the right caustic soda flakes for your business in the Gulf? Whether you run a detergent factory, a water treatment plant, or a cleaning supplies company, understanding the grades and types of caustic soda can save you time, money, and a lot of confusion.
At OozeChem, your trusted caustic soda flakes supplier in UAE and across all Gulf countries, we’re here to make this chemical crystal clear (pun intended!). Let’s dive into everything you need to know from the caustic soda formula to the best applications and how to choose the right grade for your needs.
What Is Caustic Soda?
Caustic soda, also known as sodium hydroxide, is a powerful alkali used in nearly every industry from soap manufacturing to water purification. Its chemical formula is NaOH, which stands for sodium (Na), oxygen (O), and hydrogen (H). In simple terms, that’s what caustic soda is made of. This highly versatile compound comes in several forms, including caustic soda flakes, caustic soda pearls, and caustic soda liquid, each offering distinct advantages depending on your application and industry needs.
Types: Flakes, Pearls, and Liquid
Think of these types as the same ingredient just in different “packaging.”
Caustic Soda Flakes
These are white, brittle flakes of sodium hydroxide. They’re easy to store, dissolve, and transport.
Best for: Soap making, cleaning products, textiles, and water treatment.
Fun fact: Most industries in the UAE and Saudi Arabia prefer flakes for their long shelf life and ease of handling in dry Gulf climates.
Caustic Soda Pearls
Tiny, round beads that look a bit like small white pearls.
Best for: Automated systems and industries that require precise dosing.
Why choose pearls? They create less dust and dissolve faster than flakes.
Caustic Soda Liquid
A ready-to-use liquid form (usually 50% NaOH).
Best for: Large-scale or continuous operations like wastewater treatment or chemical manufacturing.
Comparison of forms
| Form | Typical Use Cases | Advantages |
| Flakes | Industrial batch processes, soap & detergent lines, textile scouring | Easy to store and measure, longer shelf life |
| Pearls (prills) | Automated feeding systems, water treatment dosing, where dust control is key | Low dust, rapid dissolution |
| Liquid solution | Continuous feed processes, wastewater treatment, where the dissolution step has already been done | Ready-to-use, eliminates solid dissolution ste |
Grades of Caustic Soda
Grades define how pure your caustic soda is, while types define its physical form. So, you can have technical-grade flakes or food-grade flakes.
Let’s look at the most common grades used in the Gulf region:
| Grade | Purity Level | Typical Use |
| Technical Grade | 96–98% | Ideal for industrial use (pH control, soap, textiles, etc.) |
| Industrial Grade | 98–99% | Suitable for large manufacturing and chemical processes |
| Food Grade | ≥99% | Used for food processing and cleaning in food industries |
| Reagent/Pharma Grade | ≥99.5% | Used in laboratories and pharmaceuticals |
At OozeChem, we supply caustic soda flakes in multiple grades ensuring you get the right purity for your exact application.
Caustic Soda Applications
Soap & Detergent Manufacturing
This is one of the biggest uses in the Gulf!
NaOH reacts with fats and oils to produce soap. It’s also used to create detergents and degreasers.
Textiles & Dyeing
Textile factories use caustic soda for mercerizing cotton, a process that gives fabrics more shine and strength.
Water Treatment
Caustic soda neutralizes acids and adjusts the pH of water making it safe and stable for industrial use.
Paper & Pulp
Used to separate cellulose fibers during paper production.
Oil & Gas Refining
In refineries, NaOH helps remove acidic impurities like hydrogen sulfide and fatty acids.
Caustic Soda for Cleaning
Because it breaks down grease, oil, and organic matter, caustic soda is used in heavy-duty cleaners and drain openers.
Choosing the Right Form for Your Business
Not sure whether you need flakes, pearls, or liquid? Here’s a quick checklist:
Go for flakes if you want:
- Long shelf life
- Easy transport
- Flexibility to make your own solution
Choose pearls if you need:
- Precise dosing in automated systems
- Less dust during handling
Pick liquid if you prefer:
- Ready-to-use form
- No mixing or dissolving required
If you’re still unsure, our team at OozeChem can guide you to the best option for your process whether you’re in Dubai, Saudi Arabia, Oman, or Qatar.
