Magnesium Chloride Hexahydrate ●
TL;DR. This ingredient functions mainly as a mineral electrolyte and skin-conditioning salt, often used in bath, body, and scalp products. It can also adjust ionic strength, which may influence viscosity and emulsion behavior.
What does Magnesium Chloride Hexahydrate do in a cosmetic formula?
This ingredient functions mainly as a mineral electrolyte and skin-conditioning salt, often used in bath, body, and scalp products. It can also adjust ionic strength, which may influence viscosity and emulsion behavior.
Is Magnesium Chloride Hexahydrate clean?
It is generally well accepted in clean-beauty frameworks, with low concern at typical cosmetic levels. Higher salt loads can feel drying or sting on compromised skin, so use level and product format matter.
Is Magnesium Chloride Hexahydrate sustainable?
This material is commonly sourced from seawater, brines, or mineral deposits and is abundant. It is inorganic, so biodegradability is not the right measure, but it dissociates into naturally occurring ions and is not expected to bioaccumulate.
Is Magnesium Chloride Hexahydrate COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic formulas when sourced and processed according to the standard’s rules for mineral-origin materials. From a Green Chemistry lens, it scores well for simple composition, water compatibility, and low persistence concerns, though mining or brine extraction still carries site-specific footprint considerations.
How does Magnesium Chloride Hexahydrate work chemically?
This compound is a highly water-soluble hydrated ionic crystal made from divalent cations, halide anions, and bound water. It is stable across normal cosmetic pH ranges, but its electrolyte load can reduce the viscosity of some carbomer or acrylate gels and can shift surfactant thickening behavior.
