DEFINITION

Classification: 510/532

Aluminum or boron containing metal silicate component (e.g., aluminosilicate, zeolite, etc.):

(under subclass 531) Compositions which include a component which is a metal salt of a silicate which is combined with aluminum or boron.

(1) Note. The action of such components is usually via the ion-exchange mechanism, which immobilizes polyvalent metal ions.
