DEFINITION

Classification: 510/394

With nitrogen, oxygen, or sulfur containing optical brightener, ultraviolet absorber, antistatic or fiber softening component:

(under subclass 108) Compositions which additionally include a component containing oxygen, nitrogen, or sulfur which absorbs ultraviolet radiation, or which fluoresces and imparts a brighter, less dingy (e.g., white or bluish) hue to a substrate, or which eliminates or reduces static electrical charge on the cleaned substrate, or imparts a softer feel to fibrous articles treated therewith in the course of cleaning.

(1) Note. Optical brighteners are also referred to as optical bleaches, which are distinct from chemical bleaches.

(2) Note. The optical brightener may be present to improve the appearance of the cleaning composition, per se, rather than brightening the substrate cleaned therewith.

(3) Note. The fibrous articles which are softened herein are

generic in nature and include non-textile fibers, such as hair, etc.
