Request SDS →Magnesium aluminum silicate (CAS 1327-43-1) is a refined smectite-clay mineral. It is used as a rheology modifier, suspending agent, and thickener in coatings, personal care, and household products, and as an anticaking agent, opacifier, and absorbent.
Frequently Asked Questions
What is magnesium aluminum silicate used for?
Magnesium aluminum silicate (CAS 1327-43-1) is a refined smectite-clay mineral used as a rheology modifier, suspending agent, and thickener in coatings, personal care, and household products. It also functions as an anticaking agent, opacifier, and absorbent.
Does magnesium aluminum silicate contain aluminum?
Yes. It is a naturally occurring smectite clay whose structure includes both magnesium and aluminum within the silicate lattice (formula reported as AlMgO4Si). The aluminum is bound in the mineral framework, not present as free metal.
What is magnesium aluminum silicate used for in formulations?
In aqueous formulations it thickens and imparts yield value, suspends pigments and actives against settling, and acts as an opacifier and absorbent. In powders it serves as an anticaking, free-flow agent.
Is VEEGUM the same as magnesium aluminum silicate?
VEEGUM is a well-known trade name for refined magnesium aluminum silicate clay grades. The generic material under CAS 1327-43-1 covers the same smectite-clay chemistry; verify grade-specific properties against the supplier specification.
How is bulk magnesium aluminum silicate supplied and priced?
It is supplied as a refined mineral powder in bulk for coatings, personal-care, and household formulation. Pricing depends on grade, volume, and packaging; request a bulk quote with CoA and SDS for your target quantity.
