Magnesium Sulfate Synthetic ●
TL;DR. This ingredient is an inorganic salt used as a viscosity modifier, bulking agent, and stabilizing electrolyte, especially in bath products, scrubs, and some emulsion systems. It can also adjust the feel of water-based formulas by increasing ionic strength.
What does Magnesium Sulfate Synthetic do in a cosmetic formula?
This ingredient is an inorganic salt used as a viscosity modifier, bulking agent, and stabilizing electrolyte, especially in bath products, scrubs, and some emulsion systems. It can also adjust the feel of water-based formulas by increasing ionic strength.
Is Magnesium Sulfate Synthetic clean?
From a clean-beauty perspective, it is generally well tolerated and not a common restricted-list concern. At high levels, it can feel drying or cause temporary stinging on compromised skin because it is a highly water-soluble salt.
Is Magnesium Sulfate Synthetic sustainable?
This material is typically mineral-derived or made through simple inorganic processing. It is water soluble, does not bioaccumulate, and is not assessed by biodegradability in the same way as carbon-based ingredients.
Is Magnesium Sulfate Synthetic COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic formulations when it meets the standard’s mineral and processing requirements. Its Green Chemistry profile is straightforward, with simple inorganic chemistry, low bioaccumulation concern, and minimal solvent burden.
How does Magnesium Sulfate Synthetic work chemically?
This compound is an inorganic ionic salt that dissociates in water into divalent alkaline-earth cations and inorganic oxoanions, and hydrated raw-material forms are common. It is stable across normal cosmetic pH ranges and is used from low electrolyte levels in emulsions to much higher levels in bath preparations, where solubility and skin feel drive the formula limit.
