Our sodium hydroxide liquid 50% (liquid caustic soda solution) is a highly purified, industrial-grade alkaline solution manufactured for heavy-duty chemical processing. Pre-dissolved at a consistent 50% concentration, this liquid formula completely eliminates manual solids mixing, drastically lowering labor costs, process downtime, and safety hazards related to heat spikes or airborne chemical dust.
Engineered to meet stringent industrial specifications, sodium hydroxide liquid delivers predictable alkalinity and rapid reactivity for wastewater treatment, pH stabilization, soap and detergent saponification, pulp delignification, and automated Clean-in-Place (CIP) systems. We provide reliable supply continuity across global markets, supplying 50% liquid sodium hydroxide packaged in UN-rated 25kg jerrycans, 1000L IBC totes, or ISO tank bulk deliveries with full COA and SDS certification.
Product Overview
Sodium hydroxide liquid (50% caustic soda solution) is a foundational, heavy-duty strong base used extensively across modern chemical manufacturing and industrial processing. Appearing as a clear, odorless, and colorless solution, liquid sodium hydroxide delivers unmatched dosing precision when integrated into automated, continuous liquid-injection systems—a clear operational advantage over solid flakes or pearls.
By opting for ready-to-use liquid sodium hydroxide, industrial facilities significantly streamline daily operations, eliminate the need for costly solid-dissolving infrastructure, and reduce mechanical wear and corrosion on dry-handling machinery. Most importantly, utilizing a pre-dissolved liquid format completely eliminates airborne caustic dust hazards, protecting plant operators from hazardous exposure and creating a safer, more efficient working environment.

Water & Wastewater Treatment: Rapidly neutralizes acidic process streams, controls pH in municipal plants, and facilitates heavy metal precipitation.
Soaps & Detergents Manufacturing: Serves as the key saponification base in producing liquid soaps, industrial degreasers, and commercial surface cleaners.
Pulp & Paper Processing: Essential for wood chip delignification in Kraft pulping, pulp bleaching, and de-inking recycled fibers.
Food & Beverage Equipment Sanitation (CIP): Deployed in automated Clean-in-Place systems to dissolve organic deposits, proteins, and grease from stainless steel lines.
Chemical Synthesis & Refining: Acts as a fundamental reactant in producing sodium-based organic/inorganic compounds, textiles, and alumina.
Key Commercial Advantages
Seamless Process Automation: The ready-to-pump liquid format integrates directly into automated dosing networks and continuous chemical injection systems, completely eliminating the need for expensive dissolution mixing tanks and high-maintenance dry-feeder equipment.
Enhanced Operational Safety: Using pre-dissolved liquid prevents severe exothermic heat spikes and eliminates airborne corrosive dust particles, safeguarding facility operators from hazardous chemical inhalation and severe burns during handling routines.
High-Purity Performance: Manufactured with ultra-low sodium chloride and trace iron impurity levels, this high-assay solution prevents equipment scaling, pipeline fouling, and unwanted side reactions in high-precision manufacturing processes.
Flexible Logistics & Secure Delivery: Shipped in UN-certified heavy-duty packaging—ranging from 25kg chemical jerrycans and 1000L IBC totes to bulk ISO tank containers—backed by full SDS/MSDS compliance documentation for safe international transport and storage.
Safety Precautions: Sodium hydroxide liquid is strongly corrosive. Operators must wear complete personal protective equipment (PPE), including chemical splash goggles, face shield, PVC/nitrile gloves, and chemical-resistant aprons.
Storage Environment: Store in a cool, dry, well-ventilated area away from strong acids and reactive metals (e.g., aluminum, zinc, tin). Maintain ambient storage temperatures above 15°C (59°F) to prevent crystallization of the 50% solution.
