Aquamin ●
TL;DR. This ingredient is a marine-derived mineral conditioning additive, mainly used to add calcium, magnesium, and trace minerals to skin care, body care, and oral-care formulas. Depending on particle size, it can also contribute mild texture, opacity, or a soft powder feel.
What does Aquamin do in a cosmetic formula?

Is Aquamin clean?
From a clean-beauty perspective, it is generally well tolerated and not a common restricted-list concern. The main quality checkpoint is supplier testing for heavy metals and other marine-source contaminants.
Is Aquamin sustainable?
This material comes from mineralized marine algae deposits, so sourcing practices matter because the resource can be slow to renew. It is inorganic and does not biodegrade like a plant oil or sugar-derived ingredient, but it is also not a plastic or bioaccumulative silicone-type material.
Is Aquamin COSMOS-approved?
It can fit COSMOS-natural when the source, harvesting, processing, and contaminant controls meet the standard’s requirements, while its mineral fraction does not count as organic content. Its Green Chemistry profile is strongest on simple physical processing and weak on renewability, because the feedstock is a slow-forming marine mineral resource.
How does Aquamin work chemically?
This compound is a porous multi-mineral matrix dominated by calcium carbonate, with magnesium and trace elements embedded in the structure. In cosmetics it is usually used at low single-digit percentages, is stable across normal cosmetic pH ranges, and is best dispersed well to manage grittiness or settling.
