Sodium Hydroxide 25%

Product Overview

Alliance Chemical provides premium Sodium Hydroxide 25% solution, a highly alkaline liquid formulation tailored for commercial and industrial processes. This product, also known as liquid caustic soda, features the molecular formula HNaO and has a molecular weight of 39.997 g/mol — critical properties for standard chemical formulation calculations. Our 25% concentration offers a stable, pre-diluted format that minimizes the safety hazards and exothermic risks associated with dissolving solid sodium hydroxide flakes or beads on-site. It serves as a vital pH regulator, reactant, and processing aid across numerous manufacturing sectors.

With a CAS number of 1310-73-2, this colorless and odorless liquid is more dense than water, with a density of 1.5 at 68 °F (USCG, 1999). It is highly soluble in water and exhibits a strongly alkaline pH even in highly diluted solutions. Alliance Chemical distributes this versatile base across our Bases collection in various packaging configurations, from single quarts to multi-gallon cases, ensuring that your facility receives the exact volume required for seamless operations. This chemical is corrosive to metals and tissues, requiring strict adherence to standard industrial handling protocols.

Why This Grade

Selecting a 25% concentration of sodium hydroxide is critical for processes where precision pH adjustment and chemical reaction rates must be tightly controlled. This specific concentration prevents the severe crystallization and freezing issues common with higher concentration solutions (such as 50% caustic soda) in colder climates, while still providing sufficient chemical strength for heavy-duty applications. For facilities without specialized dilution equipment, utilizing a pre-formulated 25% solution eliminates operational variability and ensures consistent batch quality.

Utilizing the incorrect concentration or an uncertified grade can lead to catastrophic process failures, such as localized overheating from unexpected exothermic dilution, rapid equipment corrosion, or unwanted precipitation in process piping. In municipal and industrial wastewater systems, using an inconsistent concentration can disrupt the delicate chemical balance, leading to discharge permit violations. By sourcing this standard 25% solution, operators can guarantee predictable neutralization curves and avoid the structural damage associated with runaway alkaline reactions.

Industrial Applications

• Water Treatment: Used extensively for pH adjustment and neutralization of acidic waste streams in industrial water systems to meet discharge regulations.
• Chemical Manufacturing: Serves as a fundamental reactant in the synthesis of sodium salts, plastics, and various organic compounds across several chemical industries.
• Pulp and Paper: Utilized in the pulping and bleaching processes to break down lignin and prepare wood fibers for high-quality paper production.
• Metal Processing: Employed as an effective metal degreaser and etcher in electroplating, cleaning, and surface finishing operations across manufacturing lines.
• Textile Processing: Used in the mercerization of cotton fibers to improve dye absorption and tensile strength in commercial textile manufacturing facilities.

Hazmat & Shipping

Sodium Hydroxide 25% is classified as a hazardous material for transport and is fully regulated. It is shipped under the proper shipping name Sodium hydroxide solution, designated as UN1824, Hazard Class 8 (Corrosive), and assigned to Packing Group II. The signal word for this chemical is Danger. Due to its corrosive nature, shipping must comply with all DOT hazmat regulations. Our logistics team handles these shipments via specialized carriers to ensure safe transport from our Texas facility to your delivery site.

According to its GHS classification, this material carries hazard statements H290 (May be corrosive to metals) and H314 (Causes severe skin burns and eye damage). Personnel handling this chemical must wear mandatory Personal Protective Equipment (PPE) to mitigate exposure risks. This includes chemical-resistant gloves, protective clothing, splash-resistant goggles, and a full face shield. Ensure eye wash stations and emergency safety showers are accessible in the immediate handling area. A comprehensive Safety Data Sheet (SDS) is provided with every order to guide safe handling protocols.

Handling & Storage

Store Sodium Hydroxide 25% in a cool, dry, well-ventilated area away from incompatible materials. This solution must not be stored in containers made of aluminum, zinc, tin, or other reactive metals, as contact generates flammable hydrogen gas. Compatible storage materials include high-density polyethylene (HDPE), polypropylene, or specifically lined steel tanks. Maintain storage temperatures above the freezing point of the solution to prevent crystallization. Keep containers tightly closed when not in use and store away from strong acids, organic chemicals, and oxidizing agents to prevent highly exothermic reactions.
