The Health Effects of Potassium Chloride Exposure to Skin

Potassium Chloride (KCl) is a metal-halide salt containing both potassium and chlorine. Like all other salts, it is crystalline in nature. When in its pure state, potassium chloride is colorless (or white) and odorless. Potassium chloride is sometimes called muriate (hydrochloride) of potash, especially when used as a fertilizer. Naturally present in minerals, sylvites and carnallites, potassium chloride plays an important role in 305 bodily functions, including new cell formation in the brain. Potassium chloride overdose, however, is not beneficial to human body, and its absorption can take place through skin.

Effects on Skin

• Although, potassium chloride is used in many vital functions of the body, if used in excess, it can be dangerous and may even lead to death. The American Journal of Nutrition published a review on the effects of potassium chloride on skin. It reported that, “When the salt comes in contact with skin, especially wet or moist skin, it can produce rashes, itching or hives (hives are raised, itchy, red blisters on the surface of the skin), swelling of the mouth, face and lips, as well as a whitish-grey coating at the base of the tongue. “

Effects on Epidermis

• When excess potassium chloride is absorbed through skin, the epidermal cells release potassium chloride molecules as a result of skin irritation. Fibrin (a white insoluble fibrous protein) is thrown out as white exudations that convert into dried, scaly eruptions. In the event of severe skin rash, the irritation extends to the tissues underneath the epidermis and both the serum and fibrin are affected. As a result, the skin will also exude out as blisters. Affected tissues can again be restored by proper administration of potassium chloride.

Effects of Potassium Chloride Absorbed into the Body System

• Apart from direct oral consumption, absorption of potassium into the body system can also happen through the skin. The Encyclopedia Britannica reports that “Potassium chloride consumed through the skin can cause weakness, gastrointestinal irritation and even disorders in the blood circulation.” Potassium ions typically concentrate in the cells, leading to an accumulation in the body. This could cause severe health problems in people who have preexisting kidney and liver problems. Journal of the American Medical Informatics Association (JAMIA) cites that “Excessive amount of potassium chloride in human body can cause irritation in the respiratory ophthalmic systems and higher intakes can even lead to a fluid build-up in the lungs, which can be fatal.” If potassium chloride comes in direct contact with the skin or eyes, it can potentially cause severe burns or even permanent damage.
