DEFINITION

Classification: 516/41

The agent contains organic compound containing sulfoxy*:

(under subclass 38) Subject matter in which the colloid system making or stabilizing agent* contains an organic* compound which contains sulfoxy*.

(1) Note. Thios, thioethers, and other non-oxygenated sulfur groups are not provided for here.
