Claim 4

A colored solid particle as in claim 1 wherein the colorant extender is propylene glycol.

Claim 5

A colored solid particle as in claim 1 wherein the pigment has a reflectance value in the 450 to 535 millimicron wave length region of the visible spectrum.

Claim 6

A colored solid particle as in claim 1, having a diameter of 0.15 mm to 2.0 mm.

Claim 7

A colored solid particle as claimed in claim 1 further containing at least one member selected from the group consisting of sodium carbonate, tri-sodium phosphate, borax and tripolyphosphate.

Claim 8

A scouring cleanser consisting essentially of the particles of claim 1, from 45 to 95 percent by weight of a substantially white colored abrasive selected from the group consisting of silica, feldspar, pumice, volcanic ash, diatomaceous earth, talc, calcium carbonate and bentonite, said abrasive having a higher light reflectance value of at least about 80 percent measured at about 550 mm, and a particle size of about 0.001 mm to 0.4 mm, from about 0.5 to 30 parts by weight of the composition of a water soluble detergent selected from the group consisting of anionic, cationic, amphoteric, and nonionic detergents stable in the presence of a hypohalide-liberating bleaching agent and compatible with the remaining ingredients of the scouring composition, from 0.1 to 25 percent by weight of a hypohalide bleaching agent capable of liberating hypochlorite chlorine and/or hypobromite bromine upon contact with aqueous media and from 0 to 95 percent by weight of a builder salt selected from the group consisting of trisodium phosphate, sodium acid pyrophosphate, sodium carbonate, tetra sodium pyrophosphate, sodium tripolyphosphate, sodium sulfate, sodium silicate, sodium dibasic phosphate, sodium hexametaphosphate, sodium monobasic phosphate and borax.

Claim 10

A scouring cleanser according to claim 7 wherein the builder salt is trisodium phosphate.

Claim 11

A composition according to claim 7 wherein said abrasive is silica.

Claim 12

A process for preparing the colored solid particle of claim 1 consisting essentially of the steps of; a. dry blending a water soluble particulate carrier selected from the group consisting of sodium chloride, potassium chloride and sodium sulfate with a water soluble alkali metal bromide salt; b. adding to a) a water dispersible phthalocyanine pigment stable in the presence of a hypohalide-liberating bleaching agent; c. adding a colorant extender selected from the group consisting of propylene glycol, polyethylene glycol 300 and propylene glycol phenol ether to the mixture of step b); and d. mixing the product of step c) for about 15 minutes.

Claim 13
