A clay mineral that is a hydrous silicate of aluminum and magnesium and occurs in soft amorphous masses in the cavities of certain rocks.

[Latin sāpō, sāpōn-, hair dye; see saponin + -ite.]

Smectite clays such as montmorillonite, hectorite, and saponite have been used as inorganic fillers in many polymers.
To distinguish montmorillonite from nantronite, saponite, and beidellite Li saturation and heat treatment was used (Moore and Reynolds, 1989).

Moreover, the study explains that talc is present in close proximity to the carbonate locations - rather than previously suggested saponite - and talc-carbonate alteration of high-Mg precursor rocks has taken place.
Among the new entries are aluminum hydroxide adjuvant, disodium edetate, ethyl lactate, hectorite, lactose spray dried, lauric acid, linoleic acid, raffinose, and saponite.
Saponite, a member of the smectite group, has been identified at the Canadian Museum of Nature as dull, opaque, beige, spherical aggregates in cavities in a Francon quarry dike.
