SEA WATER: what it is

Sea Water, also called Maris Aqua, is water obtained from the ocean or from inland bodies of salt water. It is not another name for purified water: seawater is a mixture in which water is accompanied by dissolved salts and other substances.

Chloride, sodium, sulfate, magnesium, calcium, and potassium are among the most abundant ions in seawater. Their amounts can vary with salinity and with the water's origin, so SEA WATER identifies a marine raw material rather than one fixed composition shared by every product.

SEA WATER: what it does in cosmetics

In cosmetics, SEA WATER can work as a solvent. In practical terms, it takes part in the water phase that dissolves or disperses soluble ingredients, helping the formula keep those components evenly distributed while the product is used.

It is also classified as a humectant, a function associated with retaining water in the preparation. Its presence can contribute to the water-based character of a formula, but it does not by itself make a cosmetic a treatment or predict a product's feel or result without the finished formulation.
