Magnesium Nitrate ●
TL;DR. This ingredient is mainly used as a stabilizing inorganic salt, often to support preservation systems and maintain formula consistency. It may also contribute ionic strength in water-based products.
What does Magnesium Nitrate do in a cosmetic formula?
This ingredient is mainly used as a stabilizing inorganic salt, often to support preservation systems and maintain formula consistency. It may also contribute ionic strength in water-based products.
Is Magnesium Nitrate clean?
From a clean-beauty perspective, it is not a common restricted-list trigger and is generally low-sensitization at typical cosmetic levels. The main caveat is context, since it often appears alongside stronger preservative systems where the companion ingredients drive most of the concern.
Is Magnesium Nitrate sustainable?
This material is mineral-derived or synthetically made from mineral feedstocks and nitric acid, so it is not renewable in the usual plant-based sense. It is water soluble and does not bioaccumulate, but it discharge can add nutrient load to waterways if released at scale.
Is Magnesium Nitrate COSMOS-approved?
It can be compatible with COSMOS-natural and COSMOS-organic formulations as a non-organic inorganic material when sourcing and processing meet the standard. Its Green Chemistry profile is mixed, with simple chemistry and low bioaccumulation balanced by nonrenewable feedstocks and it-related water-impact considerations.
How does Magnesium Nitrate work chemically?
The molecule is an ionic salt that dissociates in water into divalent mineral cations and it anions, and it is highly water soluble. It is stable across normal cosmetic pH ranges, but it can affect electrolyte-sensitive thickeners, emulsions, and polymer gels, so formulators usually account for its ionic load.
