Sea Salt / Maris Sal

TL;DR. This ingredient is used as a mineral electrolyte and viscosity modifier, especially to thicken surfactant cleansers and add a crystalline scrub or bath-soak sensory profile.

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

This ingredient is used as a mineral electrolyte and viscosity modifier, especially to thicken surfactant cleansers and add a crystalline scrub or bath-soak sensory profile.

Is Sea Salt / Maris Sal clean?

It is generally accepted in clean-beauty frameworks and has no common restricted-list concerns. At higher levels it can feel drying or sting compromised skin, so use context matters.

Is Sea Salt / Maris Sal sustainable?

This material is mineral-derived and commonly obtained by evaporating seawater or brine, with minimal chemical transformation. It is inorganic rather than biodegradable, but it dissociates into naturally occurring ions and is not associated with persistent organic pollution; concentrated brine management is the main sourcing consideration.

Is Sea Salt / Maris Sal COSMOS-approved?

It is permitted under COSMOS-natural and COSMOS-organic when sourced and processed as an allowed natural mineral ingredient, with documentation for purity and origin. From a Green Chemistry view, it scores well for simple processing and benign chemistry, though renewable feedstock language does not really apply to inorganic minerals.

How does Sea Salt / Maris Sal work chemically?

This material is an ionic crystalline mineral, primarily a 1:1 cation-anion lattice with trace magnesium, calcium, potassium, sulfate, and other minerals depending on source. In cleansers it is often used around 0.5-3% for viscosity tuning, while bath products and scrubs use much higher levels; it is pH-stable, non-oxidizing, and can thin or destabilize systems if the surfactant blend is past its electrolyte-thickening peak.
