Supplier Of High-quality Caustic Soda Liquid From Turkey and Dubai-UAE
Caustic Soda Liquid Supplier —
Bulk NaOH 50% Solution Export
from Turkey & UAE
SUHA International exports industrial-grade caustic soda liquid (NaOH 50% solution) to 40+ countries from certified manufacturers in Turkey and our Dubai Business Bay hub. Every ISO tank and IBC shipment includes a full Certificate of Analysis — guaranteed NaOH content, iron level, and chloride impurity, batch by batch.
What Is Caustic Soda Liquid (NaOH Solution)?
Caustic soda liquid — commercially known as sodium hydroxide solution (NaOH) — is one of the most widely traded industrial alkalis in the global chemical market. With CAS number 1310-73-2 and HS Code 2815.12, it is produced via the chlor-alkali electrolysis process by passing electrical current through an aqueous sodium chloride solution to yield sodium hydroxide, chlorine, and hydrogen gas simultaneously.
In commercial export form, caustic soda liquid is supplied as a clear, colorless, and odorless aqueous solution at 50% NaOH concentration (specific gravity ~1.53 g/cm³ at 20°C). Its defining properties — extreme alkalinity (pH ≥ 14), complete water miscibility, and powerful saponification and neutralization capacity — make it chemically irreplaceable across pulp and paper, chemical synthesis, water treatment, petroleum refining, and textile processing.
As a dedicated Caustic Soda Liquid Supplier operating from Turkey and the UAE, SUHA International sources NaOH 50% solution directly from ISO-certified membrane-cell manufacturers, ensuring guaranteed purity specifications per batch. We do not resell third-party stock. Every ISO tank and IBC consignment departs under full COA, SDS, and IMDG Class 8 documentation.
📊 Market Insight (2026): The global caustic soda market exceeded USD 42 billion in 2025 and is projected to grow at a CAGR of 4.2% through 2030, driven by alumina refining expansion in West Africa, pulp and paper capacity additions in Southeast Asia, and rising water treatment infrastructure spending across the Middle East and South Asia. Buyers in these corridors are consolidating sodium hydroxide supply chains around dual-origin exporters to reduce single-source risk.

Where Is Caustic Soda Liquid Used?
Understanding your production process is central to how we operate as a Caustic Soda Liquid Supplier. Below we outline the primary industries we serve and the precise role NaOH 50% solution plays in each — along with the complementary chemicals from our portfolio.
Chemical Manufacturing
Caustic soda liquid is a foundational ingredient in producing soaps, detergents, bleach, and synthetic fibers such as rayon and viscose. Its strong alkalinity neutralizes acids and drives saponification reactions in oleochemical plants. Often used alongside LABSA and SLES in surfactant and detergent formulation lines.
Water & Wastewater Treatment
NaOH solution adjusts pH in drinking water systems to reduce pipe corrosion and prevent lead leaching. In industrial effluent treatment, it precipitates heavy metals and neutralizes acidic waste streams. Complementary to Sodium Hypochlorite for disinfection in combined treatment systems.
Pulp & Paper — Kraft Process
Caustic soda liquid combined with Sodium Sulfide (Na₂S) forms "white liquor," the cooking solution for the Kraft process. NaOH breaks down lignin ether bonds while preserving cellulose chains. It is also used in bleaching and the Hydrogen Peroxide bleaching sequence for kraft and mechanical pulps.
Petroleum Refining & Biodiesel
Refineries use NaOH solution to scrub hydrogen sulfide (H₂S) and mercaptans from natural gas, LPG, and crude oil fractions, protecting equipment from corrosion. In biodiesel transesterification, caustic soda liquid is a preferred catalyst for converting vegetable oils and animal fats into fatty acid methyl esters (FAME).
Textile — Mercerization & Scouring
In cotton processing, NaOH solution at 18–25% concentration (diluted from 50% supply) is used for mercerization — swelling cotton fibers to improve luster, tensile strength, and dye uptake. Scouring with diluted caustic soda removes natural waxes, oils, and seed-coat impurities. LABSA is frequently used in the combined scouring bath.
Food Processing — E524 Applications
Food-grade caustic soda liquid (E524) is used for olive curing, cocoa alkalization (Dutch process), lutefisk preparation, pretzel glazing, and fruit peeling. It is also used to manufacture food-grade sodium salts and regulate acidity in certain processed foods. All food-grade consignments carry a heavy metals certificate alongside the standard COA.

Safe Handling, Storage & Compliance — NaOH Liquid
Any professional Caustic Soda Liquid Supplier communicates hazard information without ambiguity. Sodium hydroxide solution (NaOH 50%) is a corrosive liquid classified under UN 1824 and IMDG Hazard Class 8. It causes severe skin and eye burns on contact, generates significant heat upon dilution, and attacks aluminum, zinc, and certain polymer materials. We provide a full SDS/MSDS with every shipment and advise on NaOH GHS hazard classification per your destination country's regulatory framework.
GHS Hazard Classification
GHS05 — Corrosive (severe skin & eye burns) · GHS07 — Irritant. UN Number: UN 1824. IMDG Class 8 (Corrosive liquid). Must be segregated from acids, aluminum, zinc, tin, and moisture-sensitive materials during storage and sea transit. Refer to the IMO IMDG Code for full segregation rules.
Dilution Exotherm Risk
Dissolving or diluting NaOH solution generates significant heat. Always add caustic to water — never water to concentrated caustic — to control the exothermic reaction safely. In bulk tank handling, ensure proper vent management and slow addition protocols. Emergency cooling water must be available.
Required PPE
Chemical-resistant nitrile or neoprene gloves · Full-face splash-proof shield or sealed safety goggles · Full-body chemical-resistant coveralls or apron · Rubber boots. Emergency eyewash and safety shower within 10 seconds of any NaOH handling area. Refer to the NIOSH Sodium Hydroxide safety profile for full exposure limits.
Storage Requirements
Store in corrosion-resistant HDPE or coated steel tanks. Maintain temperature above 12°C to prevent crystallization — tank heating may be required in cold climates. Keep containers sealed to prevent CO₂ absorption, which forms Na₂CO₃ and reduces active NaOH content. Inspect storage areas for leaks regularly. Full specification maintained for 12 months in sealed containers.
