“Magnesium Aluminum Silicate?”Here!purified clay (aluminium magnesium silicate)
Appears in 1 scanned product.
In personal care
A naturally occurring clay mineral, mined and purified, made of magnesium, aluminum, silicon, and oxygen arranged in fine plate-like particles. In water it swells into a smooth gel.
Why it’s used
Formulators use it to thicken lotions and creams, keep other ingredients like pigments or oils suspended evenly instead of settling, and give a product body without feeling greasy. It shows up often in mineral makeup and some clay-based masks.
What the evidence says
The CIR safety assessment reports Magnesium Aluminum Silicate was a weak primary skin irritant in rabbits with no cumulative irritation in guinea pigs, caused only minimal eye irritation in a Draize test, showed no teratogenic or adverse fetal effects in mice, and produced no adverse effects when applied topically to human skin daily for one week. Inhalation toxicity and pneumoconiosis findings in the same document relate to occupational dust exposure during mining and processing, not to cosmetic use. Based on these cosmetic-relevant findings, the CIR Expert Panel concluded the ingredient is safe as used in cosmetic formulations.
Context
Used at low percentages, mainly in rinse-off and leave-on lotions and masks. It is not absorbed through skin in any meaningful way and is considered inert from a toxicological standpoint at cosmetic levels.
