Sodium Hydroxide or Caustic Soda, also known as lye due to its corrosive nature, is an inorganic ionic compound with chemical formula NaOH. It is used as a base in a lot of industries and applications including, but not limited to, pH regulation, soaps and detergents, salt manufacturing, electrolysis etc. It is produced by electrolysis of brine. Chlorine gas is a byproduct of this reaction. Generally, caustic soda manufacturers get into manufacturing of other downstream chlor-alkali products to utilize the chlorine gas.

The global caustic soda market size was USD 44,959.2 million in 2019 and is projected to reach USD 55,557.7 million by 2027, exhibiting a CAGR of 3.1% during the forecast period.
Caustic soda is a crucial building block for a host of important items, such as plastics, pharmaceuticals, and additives for water treatment. It is generated by the electrolysis of sodium chloride solution using one of the cell types, such as diaphragm cell and membrane cells. The pulp and paper, detergent, alumina, oil and gas, textile, and chemical industries are the main consumers of the market.
Key players are Olin Corporation, Tata Chemicals Limited, Formosa Plastics Corporation, Westlake Chemical Corporation, Occidental Petroleum Corporation, Xinjiang Zhongtai Chemical Co. Ltd, Gujarat Alkalies and Chemical Limited, Hanwha Chemical, AkzoNobel NV, Meghmani Finechem Limited.
India Caustic Soda market demand stood at 3.74 million tonnes in FY2021 and is forecast to reach 5.52 million tonnes by FY2035, growing at a healthy CAGR of 6.54% until FY2035. Caustic soda is an inorganic bulk chemical, strongly alkaline, and odourless having application in various fields like pulp and paper manufacturing, viscose yarn, staple fiber, aluminium, textiles, soaps & detergent, dyestuffs, drugs and pharmaceuticals, petroleum refining, etc. It occurs in two forms, liquid form which is called Caustic Soda lye & solid form which is called Flakes or pellets. Increasing demand from the textile and alumina sectors due to rising investments in these sectors is likely to drive the overall India Caustic Soda demand in the country.
India is a surplus in Caustic Soda production volumes with most of the plants operating at around 80-85% efficiency. However, the increase in cheaper imports has forced domestic manufacturers to curtail their margins predominantly due to the high input and logistics costs involved within the country. Although disruptions in overseas trade and nationwide lockdown weighed on the overall India Caustic Soda consumption in Q4 FY2020, strengthened India Caustic Soda demand from hand wash and soaps manufacturing industries supported the industry outlook during the Coronavirus outbreak. In addition to that, the extension of Anti-Dumping Duty on the imports of Caustic Soda from the U.S. and Saudi Arabia, as per the petition filed by the Alkali Manufacturers Association of India (AMAI) in FY2017 has given a strong boost to the domestic India Caustic Soda Industry.

Avoid surfaces with pores, like concrete or drywall, or any surface that could hold water. Try not to utilize Burning Soft drink Dots for washing garments or in a clothes washer. Lye is destructive to metals, for example, aluminum combinations, carbon steel, aroused steel, copper, and iron.
In general, stainless steels in caustic soda resist corrosion very well, particularly at lower temperatures and concentrations. The iso-corrosion curves (0.1 mm/y) for Type 304 and 316 austenitic stainless steel in pure caustic soda (NaOH).
Status of OSHA regulations: According to the OSHA Hazard Communication Standard (29 CFR 1910.1200), this material is dangerous. Significant health risks: Corrosive. Results in serious eye damage. Severe burns on the skin and damage to the eyes
NaOH corrodes metal and produces highly flammable hydrogen gas, so it cannot be stored in a zinc or aluminum container.
At 13.35 °C, the solid dihydrate may melt into a solution when heated; however, once it reaches 12.58 °C or higher. It frequently breaks down into a liquid solution and a solid monohydrate.
Plastic pipes can become warped or melted due to a chemical reaction brought on by caustic materials. Drain cleaners can damage pipes and also cause severe injuries if misused.
Keep compartments firmly shut when not being used or void. Storage: Store somewhere that is: cool, dry, with good ventilation, and away from materials that aren't compatible. The quantity stored should be kept to a minimum.
Strong acids, such as hydrochloric, sulfuric, and nitric, react with caustic soda; Water; And moisture to release heat quickly. Caustic soda reacts with metals (Like aluminum, lead, tin and zinc) To frame combustible and dangerous hydrogen gas.
Risk of Fire: The caustic soda is non-combustible; however, upon heating, it may decompose to release corrosive or toxic fumes. It may react with metals that react chemically, like aluminum, zinc, magnesium, copper, and so on. to let out hydrogen gas, which has the potential to mix explosively in the air.
Fluid scathing soft drink is accessible as a half arrangement in two fundamental grades. The electrolytic cells that are utilized in the production of caustic soda are reflected in the names of these primary grades; diaphragm grade and membrane grade.
Contact with exceptionally high groupings of caustic soda can cause severe burns to the eyes, skin, stomach-related framework or lungs, bringing about long-lasting harm or passing. Dermatitis can result from prolonged or frequent contact with the skin. Lung damage can occur if caustic soda vapor is inhaled repeatedly.
Sodium Hydroxide Polyethylene Tanks with a Service Life of 10 to 20 Years High-density linear polyethylene (HDPE) and cross-linked polyethylene (XLPE) storage containers are perhaps the most cost-effective options with a service life of 10 to 20 years. NaOH can be stored effectively in either type of container.
Caustic soda must be stored separately from other chemicals in storage areas, according to the precautions for storage. Caustic soda must be isolated from acids, metals, explosives, organic peroxides, and other substances to prevent the containers from breaking.
