Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 148 words
A laundry pre-spotter composition comprising: (1) from about 10% to about 40% by weight of a solvent for greasy material selected from the group consisting of benzyl alcohol and B-phenylethylalcohol; (2) from about 5% to about 35% by weight of a chlorine substituted aliphatic hydrocarbon solvent having from 1 to 6 carbon atoms and being a liquid at room temperature; (3) from 5% to about 20% by weight of an organic solvent selected from the group consisting of ethylene glycol, propylene glycol, and butylene glycol; (4) from about 5% to about 40% by weight of at least one nonionic surface active agent; (5) from 5% to about 30% by weight of water; and (6) from 0 to about 10% by weight of at least one anionic surface active agent; the composition in the forms of a clear, compatible, homogeneous, stable liquid having a pH of 7 to 9.
Claim 2
Dependent Claim 148 words
A laundry pre-spotter composition comprising: (1) from about 10% to about 40% by weight of a solvent for greasy material selected from the group consisting of benzyl alcohol and B-phenylethylalcohol; (2) from about 5% to about 35% by weight of a chlorine substituted aliphatic hydrocarbon solvent having from 1 to 6 carbon atoms and being a liquid at room temperature; (3) from 5% to about 20% by weight of an organic solvent selected from the group consisting of ethylene glycol, propylene glycol, and butylene glycol; (4) from about 5% to about 40% by weight of at least one nonionic surface active agent; (5) from 5% to about 30% by weight of water; and (6) from 0 to about 10% by weight of at least one anionic surface active agent; the composition in the forms of a clear, compatible, homogeneous, stable liquid having a pH of 7 to 9.
