Saponite Clay Nanoparticles

Saponite clay nanoparticles are nanometer-sized clay particles of minerals of the montmorillonite (smectite) group. Nanoparticles have a high surface area, surface acidity, and cation exchange capacity and swell in water. These characteristics make them very versatile to help improve surface integrity and composites’ mechanical and thermal properties, adjust the consistency of industrial liquid products and serve as vehicles for drug delivery.

Purity: >99%
Typical Applications

Saponite is used in ink formulation and the production of nanocomposites. Saponite nanoclays are also used in wastewater treatment. Other uses include as an absorbent to purify and decolor liquids, as a filler in paper and rubber, and as a base for cosmetics and medicines.

Packaging Options

Jars, pails, drums, multi-ply paper bags, bulk bags, and fiberboard containers.


Saponite TSCA (SARA Title III) Status: Unknown

Saponite Clay Nanoparticles CAS Number: 1319-41-1

Sustainable Qualities

Saponite Clay Nanoparticles are a sustainable and bio-based material ideal for a range of applications. Saponite Clay is a naturally occurring mineral formed when volcanic ash is exposed to water. The resulting material is highly absorbent, making it an ideal choice for a range of applications, from wastewater treatment to soil remediation. Using Saponite Clay Nanoparticles can reduce reliance on non-renewable resources and create a more sustainable, circular economy.
