DEFINITION

Classification: 510/452

Spray-dried product, or process of preparing:

(under subclass 445) Structures in the form of a particulate product made by spraying a solution, melt, or slurry of cleaning composition ingredients into a heated atmosphere, or processes of preparing the products.

(1) Note. The heated atmosphere facilitates the removal of the liquid medium and formation of the solid particles, which are usually spherelike and hollow.
