Question 1

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

Accepted Answer

This ingredient is used as a viscosity modifier in surfactant systems, a physical exfoliant in rinse-off scrubs, and a mineral bath additive. In cleansers, small amounts can help build or tune gel thickness.

Question 2

Is Maris Sal/Sea Salt clean?

Accepted Answer

This ingredient is generally well-tolerated and has little clean-standard controversy. At higher levels, it can feel drying or sting compromised skin, and coarse particles can be abrasive.

Question 3

Is Maris Sal/Sea Salt sustainable?

Accepted Answer

This material is typically sourced from evaporated brines or mineral deposits and requires relatively simple processing. It is inorganic, so biodegradation is not the right metric, but it breaks into naturally occurring ions and is not an organic persistent pollutant.

Question 4

Is Maris Sal/Sea Salt COSMOS-approved?

Accepted Answer

It is permitted in COSMOS-natural and COSMOS-organic formulations as an accepted mineral-derived ingredient, though it does not contribute organic content. Its Green Chemistry profile is strong because it is abundant, minimally processed, and does not require complex solvents or synthesis.

Question 5

How does Maris Sal/Sea Salt work chemically?

Accepted Answer

The molecule is a crystalline ionic material made mainly of paired monovalent ions, with trace minerals depending on source and refinement. Typical use is about 0.5 to 3% for viscosity adjustment in surfactant cleansers, while bath products and scrubs may use much higher levels, and excess electrolyte can thin a formula after the viscosity peak.
