Magnesium Aluminum Silicate ●
TL;DR. This ingredient is primarily a viscosity builder and suspension agent, helping emulsions, gels, masks, and toothpaste hold particles evenly and maintain a stable texture.
What does Magnesium Aluminum Silicate do in a cosmetic formula?
This ingredient is primarily a viscosity builder and suspension agent, helping emulsions, gels, masks, and toothpaste hold particles evenly and maintain a stable texture.
Is Magnesium Aluminum Silicate clean?
This material is generally well accepted in clean-beauty standards because it is inert, non-sensitizing for most users, and not a common restricted-list concern. Quality control matters because mined minerals are typically screened for trace metal impurities and microbial load.
Is Magnesium Aluminum Silicate sustainable?
This ingredient is sourced from mined mineral deposits, so it is non-renewable and carries the usual land-use and extraction footprint of mineral supply chains. It is not biodegradable in the organic-chemistry sense, but it is insoluble, inert, and not associated with meaningful bioaccumulation.
Is Magnesium Aluminum Silicate COSMOS-approved?
It is generally permitted under COSMOS-natural and COSMOS-organic formulas when sourced from natural mineral origin and processed by allowed physical methods. Its Green Chemistry fit is strongest on low reactivity, low use level, and minimal chemical processing, with the main limitation being non-renewable sourcing.
How does Magnesium Aluminum Silicate work chemically?
This compound is an inorganic, hydrated, plate-like mineral network former that swells in water and creates thixotropic viscosity, meaning formulas can pour or spread under shear, then regain structure at rest. It is commonly used around 0.5% to 3%, is stable across typical cosmetic pH ranges, and often needs good hydration time plus high-shear mixing for full thickening performance.
