DEFINITION

Classification: 510/519

Dryer-activated composition or article (e.g., rupturable capsule, reusable dispenser, etc.):

(under subclass 515) Compositions which are activated by heat of a clothes dryer and may be enclosed in a package or combined with a substrate.

(1) Note. Certain of these compositions may be enclosed in a package or dispenser which is added to the load to be laundered at the beginning of the wash cycle but the active composition is only released in the dryer. These are the so-called "through-the-wash" compositions and packages.
