DEFINITION

Classification: 252/186.31

With organic material:

(under subclass 186.3) Composition which contains an organic material, e.g., a bleaching composition comprised of sodium perborate and benzoic anhydride coated onto expanded perlite particles, etc.

(1) Note. The presence of the organic material need not be attributed exclusively to either a stabilizing agent or a material used to coat, encapsulate, impregnate, or surface modify a particle, but may function in other capacities, e.g., a filler, plasticizer, solvent, etc.
