Sea Salt/Sel Marin ●
TL;DR. This ingredient is used as a mineral exfoliant or abrasive in scrubs, a bath soak additive, and an electrolyte that can thicken certain surfactant systems.
What does Sea Salt/Sel Marin do in a cosmetic formula?
This ingredient is used as a mineral exfoliant or abrasive in scrubs, a bath soak additive, and an electrolyte that can thicken certain surfactant systems.
Is Sea Salt/Sel Marin clean?
It has strong clean-standard acceptance, with no common restricted-list issues and low allergen concern. Sensitivity is mostly use-dependent, since coarse particles or high levels can feel drying or sting on compromised skin.
Is Sea Salt/Sel Marin sustainable?
This material is commonly sourced by solar evaporation of seawater or from marine mineral deposits, with relatively simple processing. It is inorganic, so biodegradability is not the relevant measure, but it is not associated with bioaccumulation or environmental persistence concerns in typical cosmetic use.
Is Sea Salt/Sel Marin COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic products when sourced and processed according to the standard’s mineral and physical-processing rules. Its fit with Green Chemistry is strongest on minimal processing, low transformation chemistry, and no petrochemical feedstock reliance.
How does Sea Salt/Sel Marin work chemically?
The molecule profile is an inorganic crystalline electrolyte blend dominated by alkali and halide ions, with smaller amounts of magnesium, calcium, potassium, sulfate, and trace minerals. In rinse-off scrubs and bath products it can be used at very high levels, while in cleansers it is usually adjusted more carefully because electrolyte loading can first increase, then reduce, viscosity in surfactant systems.
