- Background
Sodium hydroxide is also known as lye or soda , or caustic soda 6.
At room temperature, sodium hydroxide is a white crystalline odorless solid that absorbs moisture from the air. It is a synthetically manufactured substance. When dissolved in water or neutralized with acid it releases substantial amounts of heat, which may prove sufficient to ignite combustible materials. Sodium hydroxide is highly corrosive 2.
Sodium hydroxide is generally used as a solid or a diluted in a 50% solution. This chemical is used to manufacture soaps, rayon, paper, explosives, dyestuffs, and petroleum products 2.
It is also used in processing cotton fabric, laundering and bleaching, metal cleaning and processing, oxide coating, electroplating, and electrolytic extracting. It is commonly found in commercial drain/ oven cleaners 2. According to the the FDA, sodium hydroxide is considered a direct food recognized as safe, where it serves as a pH control agent and follows good manufacturing guidelines 3.
Interestingly, sodium hydroxide has been studied for its use in the treatment of prion disease (as occurs in mad cow disease and kuru). The use of this compound has been shown to effectively reduce prion levels in an in vitro inactivation assay 1.

Sodium Hydroxide 10% forms a strongly alkaline and caustic solution. As a caustic agent, it is used to destroy organic tissue by chemical action 4.
- Mechanism of action
Because of its high-level alkalinity, sodium hydroxide in aqueous solution directly causes bond breakage in proteins (especially disulfide bridges). Hair and fingernails are found to be dissolved after 20 hours of direct contact with sodium hydroxide at pH values higher than 9.2 8.
Sodium hydroxide has depilatory effects which have been described after accidental contact with solutions in the workplace. The breakage of bonds in proteins may lead to severe necrosis to the application site. The level of corrosion depends on the period of contact with the tissue, and on the concentration of sodium hydroxide 8.
- Absorption
There are no quantitative data for the absorption of sodium hydroxide through the skin. Solutions which contain 50 % sodium hydroxide have been shown to be corrosive and lethal when applied dermally to mice 9.

Human poisoning cases indicate that a dose of 10 grams orally is fatal 5. Sodium hydroxide is toxic by oral ingestion 2.
Sodium hydroxide is corrosive to all tissues. Concentrated vapors lead to serious damage to the eyes and respiratory system. Oral ingestion of sodium hydroxide, which occurs frequently in children, causes severe tissue necrosis, with stricture formation of the esophagus, often resulting in death. Contact with the skin may result in contact dermatitis, hair loss, as well as necrosis due to severe irritation 7.
Increased incidence of esophageal carcinoma after severe intoxication with sodium hydroxide has been reported in man. In animal studies, long-term dermal contact with substances leading to pH changes in the skin causes the development of tumors, as a result of severe tissue irritation and reparative cell growth 9.
Mutagenic for mammalian somatic cells. May cause damage to the following organs: mucous membranes, upper respiratory tract, skin, eyes MSDS. Tumors are not to be expected if the effects of irritation are prevented 9.
To date, there are no relevant studies of the prenatal toxic effects of sodium hydroxide 9.
