This is 100g of Potassium iodide supplied in very strong box with tamper proof seal.

Potassium iodide is a salt, similar to table salt. Its chemical symbol is KI. It is routinely added to table salt to make it “iodized.” Potassium iodide, if taken in time and at the appropriate dosage, blocks the thyroid gland’s uptake of radioactive iodine and thus could reduce the risk of thyroid cancers and other diseases that might otherwise be caused by exposure to radioactive iodine that could be dispersed in a severe nuclear accident.

Since potassium iodide possesses antimicrobial properties, its solution form is applied as an emergency care for open wounds.In some regions, KI is used for drinking water treatment, and its dilute form is applied for sensitization purpose. Industrial uses of potassium iodide include making dyes, soaps, lubricants and photography film emulsions.

Potassium iodide stimulates the salivary glands and can be used to treat coughs and as an expectorant. It helps loosen and break up mucus produced in the respiratory tract by chronic respiratory problems, such as asthma, bronchitis or emphysema.

Cutaneous Sporotrichosis is a fungus that can cause lesions on the skin. A saturated solution of potassium iodide (SSKI) can be used to treat the lesion. It is ineffective against internal, systemic infections of sporotrichosis.

In Industry
KI is a precursor to silver iodide (AgI) an important chemical in photography. KI is a component in some disinfectants and hair treatment chemicals. KI is also used as a fluorescence quenching agent in biomedical research, an application that takes advantage of collisional quenching of fluorescent substances by the iodide ion.

The major uses of KI include use as a nutritional supplement in animal feeds and also the human diet. For the latter, it is the most common additive used to “iodize” table salt (a public health measure to prevent iodine deficiency in populations which get little seafood). The oxidation of iodide causes slow loss of iodine content from iodised salts that are exposed to excess air. The alkali metal iodide salt, over time and exposure to excess oxygen and carbon dioxide, slowly oxidizes to metal carbonate and elemental iodine, which then evaporates.Potassium iodate is used to add iodine to some salts so that the iodine is not lost by oxidation.

For reasons noted above, therapeutic drops of SSKI, or 130 mg tablets of KI as used for nuclear fission accidents, are not used as nutritional supplements, since an SSKI drop or nuclear-emergency tablet provides 300 to 700 times more iodine than the daily adult nutritional requirement. Dedicated nutritional iodide tablets containing 0.15 mg (150 microgram or mcg) of iodide, from KI or from various other sources (such as kelp extract) are marketed as supplements, but they are not to be confused with the much higher pharmaceutical dose preparations.

Pharmaceutical applications
Potassium iodide can be conveniently prepared as a saturated solution, abbreviated SSKI. This method of delivering potassium iodide does not require a method to weigh out the potassium iodide so it can be used in an emergency situation. KI crystals are simply added to water until no more KI will dissolve and instead sits at the bottom of the container. With pure water, the concentration of KI in the solution depends only on the temperature. Potassium iodide is highly soluble in water so SSKI is a concentrated source of KI. At 20 degrees Celsius the solubility of KI is 140-148 grams per 100 grams of water.Because the volumes of KI and water are approximately additive, the resulting SSKI solution will contain about 1.40 gram (1400 mg) KI per milliliter (mL) of solution. This is 100% weight/volume (note units of mass concentration) of KI (one gram KI per mL solution), which is possible because SSKI is significantly more dense than pure water—about 1.72 g/mL. Because KI is about 76.4% iodide by weight, SSKI contains about 764 mg iodide per mL. This concentration) of iodide allows the calculation of the iodide dose per drop, if one knows the number of drops per milliliter. For SSKI, a solution more viscous than water, there are assumed to be 15 drops per mL; the iodide dose is therefore approximately 51 mg per drop, assuming 15 drops/mL. It is conventionally rounded to 50 mg per drop.

The term SSKI is also used, especially by pharmacists, to refer to a U.S.P. pre-prepared solution formula, made by adding exactly KI to water to prepare a solution containing of 1000 mg KI per mL solution (100% wt/volume KI solution), to closely approximate the concentration of SSKI made by saturation. This is essentially interchangeable with SSKI made by saturation, and also contains about 50 mg iodide per drop.
