Question 1

What does Sea Salt/Sodium Chloride/Maris Sal do in a cosmetic formula?

Accepted Answer

This ingredient is primarily used as a viscosity adjuster in aqueous surfactant formulas, where it can thicken shampoos and body washes at low levels. In scrubs and bath products, larger crystals also provide physical exfoliation and a mineral bath feel.

Question 2

Is Sea Salt/Sodium Chloride/Maris Sal clean?

Accepted Answer

It is broadly accepted in clean-beauty standards and is not a common allergen or restricted-list concern. Clean-standard friction is low, though high levels can feel drying or sting on sensitized skin.

Question 3

Is Sea Salt/Sodium Chloride/Maris Sal sustainable?

Accepted Answer

This material is mineral-derived, usually obtained by evaporating brines or from mined deposits, and does not rely on petrochemical synthesis. It is not biodegradable in the organic-chemistry sense, but it dissociates into naturally abundant ions and is not considered a synthetic persistence concern.

Question 4

Is Sea Salt/Sodium Chloride/Maris Sal COSMOS-approved?

Accepted Answer

It is permitted under COSMOS-natural and COSMOS-organic products when sourced and processed as an allowed mineral material. Its Green Chemistry fit is strong for simple processing and low solvent burden, though mined sources are nonrenewable and biodegradability does not apply to an inorganic mineral.

Question 5

How does Sea Salt/Sodium Chloride/Maris Sal work chemically?

Accepted Answer

This material is a crystalline ionic lattice that dissociates completely in water, raising ionic strength and interacting with micelles in surfactant systems. Typical viscosity-building use is often about 0.5 to 3% in sulfate and some amphoteric or anionic cleansers, while higher additions can thin the system again, and it is stable across normal cosmetic pH and not prone to oxidation.
