Sodium hydroxide solution (NaOH) commonly known as caustic soda liquor, is supplied as a 4% by weight solution of pure sodium hydroxide powder dissolved in demin water. NaOH is a strong alkaline substance that dissociates completely in water to sodium and hydroxyl ions. The solution is slightly viscous and completely miscible with water and alcohols.
Sodium hydroxide is used to manufacture soaps, rayon, paper, explosives, dyestuffs, and petroleum products. It is also used in processing cotton fabric, laundering and bleaching, metal cleaning and processing, oxide coating, electroplating, and electrolytic extracting. It is commonly present in commercial drain and oven cleaners.
Sodium Hydroxide is manufactured by the electrolysis of salt (sodium chloride). Solid sodium hydroxide is obtained from this solution by the evaporation of water.

General Uses for Sodium Hydroxide
Sodium hydroxide is used for many applications including:
In the laboratory Sodium hydroxide has been used extensively to remove proteins from ion exchange, hydrophobic interaction, and gel filtration media. Sodium hydroxide is widely accepted for cleaning, sanitising, and storing chromatography media and systems.
Sodium hydroxide is frequently used as an industrial cleaning agent where it is often called "caustic". It is added to water, heated, and then used to clean the process equipment, storage tanks, etc. It can dissolve grease, oils, fats and protein based deposits. The sodium hydroxide solution can also be added surfactants to stabilize dissolved substances to prevent re-deposition. A sodium hydroxide soak solution is used as a powerful degreaser on stainless and glass bake ware. It is also a common ingredient in oven cleaners.
For clearing blocked drains, the caustic soda liquid is used directly by slowly pouring into the drain opening, followed by adding hot water extremely slowly and carefully.
