hand-harvested French grey sea salt ●
TL;DR. This ingredient is mainly used as a physical exfoliant in scrubs and as a mineral additive in bath products. It can also influence texture and viscosity in some rinse-off formulas.
What does hand-harvested French grey sea salt do in a cosmetic formula?
This ingredient is mainly used as a physical exfoliant in scrubs and as a mineral additive in bath products. It can also influence texture and viscosity in some rinse-off formulas.
Is hand-harvested French grey sea salt clean?
It is generally well accepted in clean-beauty frameworks and is not a typical restricted-list concern. At higher levels it can feel drying or sting on compromised skin, so placement and concentration matter.
Is hand-harvested French grey sea salt sustainable?
This material is typically collected from coastal evaporation areas with minimal processing and relatively low energy input. It is inorganic rather than biodegradable, but it dissolves into naturally occurring ions and its footprint depends mostly on responsible coastal and water-management practices.
Is hand-harvested French grey sea salt COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic formulations as a naturally derived mineral material, provided it meets purity and contamination specifications. From a Green Chemistry view, it scores well for low processing and no need for synthetic solvents, although it is not a renewable botanical feedstock.
How does hand-harvested French grey sea salt work chemically?
This material is a crystalline inorganic blend dominated by simple ions, with trace minerals and fine sediment contributing to its it color. Particle size controls exfoliation intensity, and it is highly water-soluble, heat-stable, and best kept away from eye-area or leave-on formulas at high levels.
