DEFINITION

Classification: 507/127

Organic component contains silicon attached directly or indirectly to carbon by nonionic bonding:

(under subclass 103) Composition wherein silicon is attached to organic carbon directly or indirectly by nonionic bonding.

(1) Note. Included in this subclass are silicones, siloxanes, organosilanes, alkylsilicates, etc.

(2) Note. A composition with silicon as part of a mere counterion to an ionic compound is not a basis for including such a composition in this subclass. For example, a quaternary ammonium silicate is included in subclass 129.
