Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 174 words
A peroxygen bleaching composition which comprises approximately by weight of a mixture of: (a) about 1 to about 75% of an inorganic peroxygen bleaching compound; and (b) about 1 to about 75% a peroxygen bleachant activator which is characterized by the formula: ##STR14## wherein y is 1,2 or 3, n is 1 to 10, r is 1 to 8, T, W, S and Z are independently selected from the group consisting of hydrogen, an alkyl group having 1 to about 8 carbon atoms, a halogenated alkyl group having 1 to about 8 carbon atoms, fluorine, chlorine, bromine, an alkylaryl group having about 7 to 12 carbon atoms and mixtures thereof and R 1 and R 2 are selected independently from the group consisting of alkyl groups having 1 to about 8 carbon atoms, halogenated alkyl groups having 1 to about 8 carbon atoms, cycloalkyl groups having about 5 to about 8 carbon atoms, aryl groups having about 6 to about 12 carbon atoms and alkylaryl groups having about 7 to about 12 carbon atoms.
Claim 2
Dependent Claim 174 words
A peroxygen bleaching composition which comprises approximately by weight of a mixture of: (a) about 1 to about 75% of an inorganic peroxygen bleaching compound; and (b) about 1 to about 75% a peroxygen bleachant activator which is characterized by the formula: ##STR14## wherein y is 1,2 or 3, n is 1 to 10, r is 1 to 8, T, W, S and Z are independently selected from the group consisting of hydrogen, an alkyl group having 1 to about 8 carbon atoms, a halogenated alkyl group having 1 to about 8 carbon atoms, fluorine, chlorine, bromine, an alkylaryl group having about 7 to 12 carbon atoms and mixtures thereof and R 1 and R 2 are selected independently from the group consisting of alkyl groups having 1 to about 8 carbon atoms, halogenated alkyl groups having 1 to about 8 carbon atoms, cycloalkyl groups having about 5 to about 8 carbon atoms, aryl groups having about 6 to about 12 carbon atoms and alkylaryl groups having about 7 to about 12 carbon atoms.
Claim 3
Dependent Claim 29 words
A composition according to claim 1, wherein said mixture is dissolved in water at concentration of about 0.050 to about 10 grams of said mixture per liter of water.
Claim 4
Dependent Claim 26 words
A composition according to claim 1, wherein said inorganic peroxygen bleaching compound is water soluble and is selected from the group consisting of monopersulfates and monoperoxyphosphates.
Claim 5
Dependent Claim 19 words
A composition according to claim 3, wherein T,Z,W and S are hydrogen, y=2 and n equals 2 to 6.
Claim 6
Dependent Claim 50 words
A composition according to claim 3, wherein T and Z are hydrogen, y is 1, n is 2 to 6, W and S are independently selected from the group consisting of hydrogen and an alkyl group having 1 to 3 carbon atoms and r is equal to 1 to 4.
Claim 7
Dependent Claim 39 words
A composition according to claim 1 further including at least one nonaqueous liquid carrier, said mixture of said inorganic peroxygen bleaching compound and said peroxygen bleachant activator being at a concentration of about 0.05 to about 10 wt. %.
Claim 8
Dependent Claim 48 words
A composition according to claim 6 further including at least one other ingredient selected from the group consisting of an antifoam agent, a thickener, a surfactant, a fabric softener agent, an antistatic agent, a stabilizer, an inorganic builder salt, an enzyme, an alkali metal silicate and mixtures thereof.
Claim 9
Dependent Claim 38 words
A composition according to claim 6 further including at least one other ingredient selected from the group consisting of a surfactant, an antifoam agent, a fabric softener agent, an antistatic agent, a stabilizer, a silicate and mixtures thereof.
