MAGNESIUM SULFATE ●
TL;DR. This ingredient is mainly used as an electrolyte and viscosity modifier, especially to help stabilize water-in-oil emulsions. It also appears in bath products as a mineral salt and in some formulas as a bulking or texture-support ingredient.
What does MAGNESIUM SULFATE do in a cosmetic formula?
This ingredient is mainly used as an electrolyte and viscosity modifier, especially to help stabilize water-in-oil emulsions. It also appears in bath products as a mineral salt and in some formulas as a bulking or texture-support ingredient.
Is MAGNESIUM SULFATE clean?
From a clean-beauty perspective, this ingredient is generally low concern and is not a common restricted-list trigger. It is usually well tolerated, though high-salt formulas can feel drying or sting on compromised skin.
Is MAGNESIUM SULFATE sustainable?
This material is an inorganic mineral salt, typically obtained from mineral sources or made by simple neutralization chemistry. It is highly water soluble, does not bioaccumulate, and has low environmental persistence concern, although mineral sourcing is not renewable in the agricultural sense.
Is MAGNESIUM SULFATE COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic frameworks when it meets mineral and processing requirements. Its Green Chemistry profile is straightforward, with simple composition, low bioaccumulation concern, and low processing complexity, balanced by non-renewable mineral sourcing.
How does MAGNESIUM SULFATE work chemically?
This compound is a highly water-soluble inorganic electrolyte made from a divalent alkaline-earth metal ion and an oxyanion, often supplied as hydrated crystals. Typical use ranges are about 0.5% to 3% for emulsion stabilization or viscosity adjustment, while bath products can use much higher levels, and it remains stable across normal cosmetic pH ranges.
