Sea salt is 95% sodium chloride. The rest contains minerals like magnesium, potassium, calcium, iron and sulfur. Very small amounts of iodine, zinc and manganese can be found.
The use of sea salt has positive effects on the skin: cleansing, smoothing, hydrating, relaxing, detoxifying, promoting better blood circulation and is said to accelerate wound healing.
The salt used in tubbubble products comes from France (Bretagne), Australia and the Netherlands Antilles and is a mix of fine and coarse granulations, obtained by evaporating sea water. 100% natural, the sea salt is cleaned with its own natural brine so no potable water is wasted. The crystals are free from pesticides, heavy metals, waste and radioactivity.
