The name bath salts is applied to a range of soluble, usually inorganic solid products designed to be added to a bath, either to improve cleaning, provide a medical improvement, to improve the experience of bathing, or to serve as a vehicle for cosmetic agents.

Such salts include:

• magnesium sulfate (Epsom salts)
• sodium chloride (table salt)
• sodium bicarbonate (baking soda)
• sodium hexametaphosphate (Calgon, amorphous/glassy sodium metaphosphate)
• sodium sesquicarbonate
• borax

Though most bath salts contain only trace amounts of mineral additives the prices of the products can vary in the extreme.

A box of Epsom Salts can be as little as a dollar a pound while a product containing “Dead Sea Salts” can run in to the hundreds.

Although many organic substances commonly used in or with bath water are salts (such as soap and many other surfactants), these are not usually called "bath salts". However, this does not rule out the possibility of low formula weight organic salts such as sodium citrate being called bath salts.

As with the naming of other additives, mixed preparations consisting largely though not entirely of salts as described herein may be called "bath salts". Commonest additions are fragrances and colors, and one purpose (in some products the most important one) of salts is as a vehicle or diluent to "stretch" fragrances, which are otherwise often too potent for convenient measurement or use. Other common additives to bath salts are oils (agglomerating the salts, the product being called "bath beads" or "bath oil beads"), foaming agents, and fizzing (effervescent) agents.

The appearance of the product before use is sometimes valued, and although bath salts are often packaged for retail in windowless boxes or bags, they may also be displayed in transparent containers. For instance, the needlelike appearance of sodium sesquicarbonate crystals makes them attractive for such purpose. However, bath salts may also be prepared as amorphous granules rather than crystals.

[edit] History of bath salts

The earliest form of systematic explanation about the different kinds of salts, its uses, and the methods of its extraction was published in China around 2700 years B.C. Hippocrates encouraged his fellow healers to make use of salt water to heal various ailments by immersing their patients in sea water. The ancient Greeks continued this and in 1753, English author and physician Dr. Charles Russel published "The Uses of Sea Water".^[1]

[edit] Effects of bath salts

Epsom salt is the most tested and has many effects on the muscles and nervous system.

Bath salts provide a variety of benefits to a bather. Salts change the osmotic balance of the water so that fewer salts are leeched from the skin via osmosis. This reduces the "pruning" or "wrinkling" effect of prolonged exposure of skin to fresh water. Magnesium sulphate has been shown to be absorbed through the skin, and magnesium has an anti-inflammatory effect. When added to bath water Sodium Bicarbonate (Baking Soda) can help with hormonal imbalances in women which can lead to intense itching and Sodium Chloride (table salt) can also relieve some of the symptoms associated with psoriasis.^[2]

Some bath salts such as phosphates have a detergent action which softens calloused skin and aids in exfoliation.

Some bath salts act as Water softeners and change the way soap behaves and rinses.

High concentrations of salts increase the specific gravity of the water and increase buoyancy which makes the body feel lighter in the bath. Very high concentrations of salts in water are used in flotation therapy.

Bath salts are often used to mimic the properties of natural mineral baths or hot springs
