The most important are sodium, potassium, calcium and magnesium chlorides.
Human sweat is a homogeneous mixture of water, salts, and other compounds secreted by sweat glands. It also contains small amounts of urea and lactic acid, giving it its characteristic smell.
This is just protein. I think it works kind of the same way as our body excretes sweat and salts. It's harmless.
Sweat is largely water. There is no salt in human sweat. Human sweat tastes salty because it contains potassium chloride, not sodium chloride. Salt's main function is as a fluidic electrolyte in blood tissue, and is used in muscle contraction causing calcium and potassium to shift in the muscle cells, the heart muscle cells as well, allowing for engery to be used. Salt is regulated by nephrons of the kidneys (1 million in each) and is excreeted into the urine. High blood sodium/salt levels usually result in high salt content in urine. Sweat and urine are drinkable fluids in the absence of water and can save your life in a crisis.
It is not safe to eat any kind of bath salts. Bath salts are meant to be used for external purposes only, such as adding fragrance or minerals to bathwater. Ingesting bath salts can be harmful or toxic to your health.

Lipids are not salts.
mechanical weathering (by wind or water or perhaps tenacious plant roots or human activities)
Salts can be organic or inorganic, soluble or insoluble, simple or double etc., toxic or not, natural or artificial.
Melanin is not a sweat gland. Is is the chemical that provides skin color.
