Dependent Claim 16 words
A chemiluminescent detergent composition according to claim 1, wherein said detergent composition is in liquid form.
Claim 6
Dependent Claim 197 words
A substantially dry scouring powder comprising about 90 parts by weight of an abrasive powder, the balance being a detergent composition comprising a. a detergent material selected from the group consisting of anionic, nonionic, cationic, and zwitterionic detergent active materials, b. a chemiluminescer selected from the group consisting of chemical compounds having the structural formula: and sodium, potassium and lithium salts thereof, wherein R is selected from the group consisting of: NH2 NHCH3 NHC2H5 NHCH2C6H5 NHCOCH2Cl NHCOCH2NH2 N(CH3)2 N(C2H5)2, and N(CH2C6H5)2, c. an oxidizing agent selected from the group consisting of sodium perborate, potassium perborate, sodium percarbonate, hydrogen peroxide, zinc peroxide, barium peroxide, calcium peroxide, magnesium peroxide, the sodium, potassium, lithium and ammonium salts of the peroxyphosphates of orthophosphoric acid, pyrophosphoric acid and tripolyphosphoric acid, the peroxyhydrates of sodium sulphate and potassium sulphate, the sodium, potassium, lithium, calcium, magnesium and ammonium salts of the peroxyhydrates of alpha-amino phosphoric acids and the hydrogen peroxide addition products of urea, biuret and amides, and d. a halogen source, said chemiluminescer, oxidizing agent, and halogen source being present in proportions by weight reSpectively of about 1 part, about 2-5 parts, and about 0.6-1 part for 100 parts of said scouring powder.
Claim 7
Dependent Claim 16 words
A scouring powder in accordance with claim 7 wherein said chemiluminescer is encapsulated in pressure-rupturable capsules.
Claim 8
Dependent Claim 228 words
A chemiluminescent detergent composition comprising, by weight: a. from about 0.05 to about 10 percent of a chemiluminescer selected from the group consisting of chemical compounds having the structural formula: and sodium, potassium and lithium salts thereof, wherein R is selected from the group consisting of: NH2 NHCH3 NHC2H5 NHCH2C6H5 NHCOCH2Cl NHCOCH2NH2 N(CH3)2 N(C2H5)2, and N(CH2C6H5)2, b. about 0.05 to about 40 percent of a first activator for said chemiluminescer which is an oxidizing agent selected from the group consisting of sodium perborate, potassium perborate, sodium percarbonate, hydrogen peroxide, zinc peroxide, barium peroxide, calcium peroxide, magnesium peroxide, the sodium, potassium, lithium and ammonium salts of the peroxyphosphates of orthophosphoric acid, pyrophosphoric acid and tripolyphosphoric acid, the peroxyhydrates of sodium sulphate and potassium sulphate, the sodium, potassium, lithium, calcium, mangesium and ammonium salts of the peroxyhydrates of alphaamino phosphoric acids and the hydrogen peroxide addition products of urea, biuret and amides, c. from about 0.05 to about 10 percent of a second activator for said chemiluminescer selected from the group consisting of a transition metal chelate of pyridine-2-carboxylic acid, and a transition metal chelate of 1,10-phenanthroline, and d. from about 0.5 to about 60 percent of a detergent active material selected from the group consisting of anionic, nonionic, cationic and zwitterionic detergent active materials, said chemiluminescer being maintained out of contact with said activators until said composition is dispensed.
Claim 9
Dependent Claim 85 words
