Sea Salt/Maris Sal/Selmarin ●
TL;DR. This ingredient primarily acts as a mineral electrolyte that adjusts viscosity in surfactant cleansers and adds texture in bath, scrub, and body products. In solid or high-level formats, it can also provide physical polishing and a bath-soak feel.
What does Sea Salt/Maris Sal/Selmarin do in a cosmetic formula?
This ingredient primarily acts as a mineral electrolyte that adjusts viscosity in surfactant cleansers and adds texture in bath, scrub, and body products. In solid or high-level formats, it can also provide physical polishing and a bath-soak feel.
Is Sea Salt/Maris Sal/Selmarin clean?
This material is generally well accepted in clean-beauty frameworks and has low systemic concern. At higher levels or in coarse crystals, it can feel drying or sting compromised skin because of its osmotic and physical effects.
Is Sea Salt/Maris Sal/Selmarin sustainable?
This ingredient is typically sourced by seawater evaporation or mineral deposit extraction and is abundant. It is not biodegradable in the organic-chemistry sense, but it dissociates into naturally occurring ions and does not behave like a persistent synthetic organic pollutant.
Is Sea Salt/Maris Sal/Selmarin COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic formulas when obtained through permitted physical mineral processing. From a Green Chemistry view, it scores well for simple processing, broad availability, and no need for complex synthetic routes.
How does Sea Salt/Maris Sal/Selmarin work chemically?
This compound is an inorganic ionic crystal that is highly water soluble and increases ionic strength in water-based systems. In surfactant formulas, typical use is often about 0.5% to 3% for viscosity adjustment, with over-addition potentially reducing viscosity after the system passes its electrolyte response peak.
