Sodium ●
TL;DR. It has no typical direct formulation role in finished beauty products; as the free elemental material, it is too reactive for ordinary aqueous, emulsion, or anhydrous consumer formulas. When related ionic forms appear in formulas, they usually serve as counterions, pH adjusters, or parts of salts, but that is not the same as using this material directly.

Is Sodium clean?
From a clean-standard view, this material has major formulation incompatibility rather than a classic restricted-list controversy. It reacts instantly with water and can create very high-pH conditions, so it is not a normal intentional ingredient in finished personal-care products.
Is Sodium sustainable?
It is produced industrially from mineral brine or molten salts using energy-intensive electrolysis. It does not bioaccumulate as the free metal in cosmetic use because it reacts immediately, but its manufacture carries an electricity footprint.
Is Sodium COSMOS-approved?
This material is not aligned with COSMOS-natural or COSMOS-organic finished-product use as a direct cosmetic ingredient. Green Chemistry fit is weak because production relies on high-energy electrolysis and the free metal is incompatible with water-based, benign processing.
How does Sodium work chemically?
This is a monovalent, highly electropositive metal that rapidly reacts with water to form a strongly alkaline solution and hydrogen gas. There is no normal leave-on or rinse-off use level because it is incompatible with aqueous cosmetic systems; formulators use stable salts or derivatives when they need the cation or alkalinity.
