Maris Sal ●
TL;DR. This ingredient is mainly used as a mineral additive and texture modifier. It can adjust viscosity in surfactant systems and add a crystalline feel to scrubs, bath products, and rinses.
What does Maris Sal do in a cosmetic formula?
This ingredient is mainly used as a mineral additive and texture modifier. It can adjust viscosity in surfactant systems and add a crystalline feel to scrubs, bath products, and rinses.
Is Maris Sal clean?
From a clean beauty perspective, it is generally well-tolerated, simple, and not a common restricted-list concern. High levels may feel drying or sting on compromised skin because of its osmotic effect.
Is Maris Sal sustainable?
This material is typically obtained by evaporating marine brine, with relatively simple processing compared with many synthetic inputs. It is inorganic and does not biodegrade in the usual sense, but it dissociates in water and is not associated with bioaccumulation concerns.
Is Maris Sal COSMOS-approved?
It is permitted under COSMOS-natural and may be used in COSMOS-organic formulas as an allowed mineral ingredient, though it does not count toward organic content. Its Green Chemistry profile is favorable for simple sourcing and low chemical transformation, with the main caveat being energy use in evaporation and concentration management in wastewater.
How does Maris Sal work chemically?
The material is an inorganic crystalline mixture dominated by simple chloride salts of alkali and alkaline-earth metals, with minor minerals varying by source. In surfactant systems it is often used around 0.5 to 3% to build viscosity in anionic blends, while excess can thin formulas past the electrolyte curve; it is pH-stable, non-oxidizing, and can increase corrosion risk for metal packaging.
