What is Liquid Caustic Soda?
Caustic soda liquid is a powerful neutralizing fluid made from sodium hydroxide. Widely used across various industries, it plays a key role in both heavy-duty cleaning and manufacturing processes.
Typically available in concentrations of either 32% or 50%, the stronger 50% solution is a clear, odorless liquid. The caustic soda liquid density is about 1.54 g/cm3.
Production Process of Liquid Caustic Soda
Brine, a simple sodium chloride solution in water, is electrolyzed to start the lye-making process. By passing an electric current through the brine, the sodium and chloride ions are separated.
The sodium ions then combine with hydroxide ions to form sodium hydroxide, which is collected as a liquid.
Various kinds of electrolytic cells can be used for this electrolysis. A permeable separator divides the anode and cathode in the diaphragm cell to prevent the mixing of sodium hydroxide and chlorine gas.
In the mercury cell, the cathode employs mercury, facilitating the reaction where sodium mixes with water to produce a stable sodium amalgam.
Liquid Caustic Soda Types
Lye comes in a range of grades, types, and forms, tailored to different industrial needs. Here are the most commonly available grades:
- Commercial Grade: Primarily used in a variety of industries, including pulp and paper production, petroleum refining, and textile manufacturing.
- Chemical Grade: Designed for more specialized applications, this grade is often found in pharmaceuticals and the production of fine chemicals.
- Food Grade: As the name suggests, this grade is safe for food processing and is commonly used in the production of chocolate, cocoa, and caramel.

What is Liquid Caustic Soda Used for?
How does caustic soda work? Its strong alkaline nature makes it a critical component in a broad spectrum of manufacturing and processing operations across numerous industries.
Chemical Manufacturing
Around 40% of all caustic soda produced is used in the chemical industry, where it serves as a key reagent in countless industrial processes.
Pulp and Paper Industry
In pulp production, lye plays an essential role during the bleaching process. It helps remove lignin from both sulfate and sulfite pulps during the extraction phase in multistage bleach plants.
In kraft mills, liquid caustic soda often acts as a replenishing agent, and it’s also applied during the early stages of recycling paper, especially for de-inking purposes.
Rayon and Cellophane Production
The viscose technique relies significantly on lye. At first, cellulose is treated with a caustic soda solution to produce alkali cellulose. This is subsequently dissolved in a diluted solution to form viscose, which is then spun into fibers or films.
Aluminum Processing
In the production of alumina from bauxite ore, lye is used to break down the ore and extract aluminum oxide. It’s also valuable in etching and chemical milling processes involved in refining aluminum parts.
Soap Production
Soapmaking would be impossible without Liquid caustic soda. It reacts with fats in a process called saponification, transforming them into water-soluble sodium soaps.
Textile Industry
Textile processing uses lye in various stages, including scouring, bleaching, and removing sizing agents. It also enhances fabric quality through mercerizing and lustering treatments.
Oil and Gas Refining
In petroleum refining, lye is employed to destroy acidic. It also plays a role in sweetening processes, where it helps neutralize unpleasant sulfur compounds using chlorine.
Substitute for Soda Ash
In several sectors, such as glassmaking, paper production, and the manufacture of phosphates and silicates, lye can be used as an alternative to soda ash.
Renewable Energy
Lye contributes to biofuel production by adjusting pH levels and aiding in the formation of sodium methylate, which is essential in biodiesel and bioethanol processing.
Tips for Purchasing Liquid Caustic Soda
Choosing the right supplier for lye is crucial to ensure you get quality products, reliable service, and smooth delivery. Here are some key tips to help you select the best supplier for your business, ensuring you get the best value and reliability in every transaction.
- Choosing the Right Caustic Soda Supplier: When picking a supplier, look for competitive prices, reliable delivery, and smooth shipping. Make sure they offer both good rates and trustworthy service.
