French Sel De Mer ●
TL;DR. This ingredient is used mainly as a mineral abrasive in scrubs and a soaking additive in bath products. It can also help adjust viscosity in some rinse-off surfactant formulas.
What does French Sel De Mer do in a cosmetic formula?
This ingredient is used mainly as a mineral abrasive in scrubs and a soaking additive in bath products. It can also help adjust viscosity in some rinse-off surfactant formulas.
Is French Sel De Mer clean?
From a clean-beauty perspective, it is generally well accepted and has no common restricted-list friction. The main practical caveats are physical abrasion in scrub formats and possible stinging on compromised skin at high levels.
Is French Sel De Mer sustainable?
This material is typically obtained by evaporating coastal water, often with relatively simple processing. It is inorganic, so biodegradability is not the right measure, but it does not create the same persistence concerns associated with synthetic polymers or silicones.
Is French Sel De Mer COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic standards when sourced and processed as an allowed mineral material. Its Green Chemistry profile is favorable when produced by solar evaporation or other low-input methods, with minimal chemical transformation.
How does French Sel De Mer work chemically?
The molecule profile is an inorganic crystalline mineral matrix dominated by sodium and chloride ions, with smaller amounts of magnesium, potassium, calcium, sulfate, and carbonate ions depending on origin. Use levels vary widely by format, from low single digits for texture or viscosity effects to very high percentages in bath soaks and anhydrous scrub blends.
