Sea Water ●
TL;DR. This ingredient functions mainly as a formulation solvent or diluent, with a secondary role as a source of dissolved minerals and salts. It is most common in mists, cleansers, bath products, and mineral-positioned skin care.

Is Sea Water clean?
From a clean-beauty perspective, it is typically low concern and well tolerated, with the main quality question being purification and testing for microbial load, heavy metals, and other environmental residues. It is not a common restricted-list issue in clean retail standards.
Is Sea Water sustainable?
It is naturally sourced and requires relatively simple processing, usually filtration, purification, and preservation support in the finished formula. Biodegradability is not the most relevant metric because it is an inorganic aqueous salt solution, but responsible sourcing and transport footprint still matter.
Is Sea Water COSMOS-approved?
It is generally permitted in COSMOS Natural and COSMOS Organic formulations when sourced and processed according to the standard, though it does not count as organic agricultural content. It fits Green Chemistry reasonably well because it is naturally derived, minimally transformed, and used without complex synthesis.
How does Sea Water work chemically?
The material is an aqueous electrolyte mixture dominated by sodium and chloride ions, with smaller amounts of magnesium, calcium, potassium, sulfate, bicarbonate, and trace elements. Its salt content can affect preservative performance, viscosity systems, and emulsion stability, so formulators usually account for ionic strength rather than treating it as a neutral diluent.
