Is alkali harmful to the human body?

Alkali is a chemical product that can be widely used in many fields, but it is very corrosive and has a bad smell. It has many benefits for our human body, such as being used for experiments. Generally speaking, chemical products are harmful to the human body, so is alkali harmful to the human body?

In industry, sodium hydroxide is usually called caustic soda, or pyrolyte or caustic soda. This is because concentrated sodium hydroxide solution splashed onto the skin will corrode the epidermis and cause burns. It has a dissolving effect on proteins and is highly irritating and corrosive (due to its dissolving effect on proteins, alkali burns are more difficult to heal than acid burns).

Dropping 0.02% solution into rabbit eyes can cause corneal epithelial damage. Mouse intraperitoneal LD50: 40 mg/kg, rabbit oral LDLo: 500 mg/kg. Dust irritates the eyes and respiratory tract and corrodes the nasal septum; if it splashes on the skin, especially on the mucous membrane, it can produce soft scabs and penetrate into deep tissues, leaving scars after burns; if it splashes into the eyes, it will not only damage the cornea, but also cause damage to the deep tissues of the eye, and in severe cases it can cause blindness; if ingested accidentally, it can cause gastrointestinal burns, colic, mucosal erosion, vomiting of bloody gastric contents, bloody diarrhea, and sometimes hoarseness, dysphagia, shock, gastrointestinal perforation, and gastrointestinal stenosis in the later stages. Due to its strong alkalinity, it can cause water pollution and attention should be paid to plants and aquatic organisms.

Dust or smoke can irritate the eyes and respiratory tract and corrode the nasal septum. Direct contact between the skin and eyes with NaOH can cause burns. Accidental ingestion can cause gastrointestinal burns, mucosal erosion, bleeding and shock.

If you are going to use alkali in an experiment, you must wear chemical safety glasses and protective clothing. Be careful when using it to avoid splashing it on your clothes or getting it in your mouth or nose. Also, take a shower and change clothes after the experiment.

Industrial pyroalkali is extremely harmful to the human body. It is a highly toxic chemical and is extremely corrosive. Just consuming 1.95 grams can cause death. If you consume food containing industrial hydrogen peroxide, it will not only strongly irritate the human gastrointestinal tract, but also pose potential hazards such as carcinogenicity, teratogenicity and gene mutation.
