Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
138 words
In an alkali metal hypochlorite bleach solution containing a perfume oil to mask the chlorine odor thereof and a dispersant for said perfume oil, the improvement which comprises said dispersant being at least one quaternary ammonium compound having the structural formula ##STR2## where R 1 is an alkyl or aromatic group containing from about 1 to 20 carbon atoms, R 2 through R 7 are selected from the group consisting of alkyl and aromatic groups containing about 1 to 14 carbon atoms, cycloalkyl groups containing about 5 to 18 carbon atoms, alkaryl groups containing from 7 to 10 carbon atoms, and pyridyl groups and X is selected from the group consisting of fluoride, chloride, nitrate, sulfate, methyl sulfate, carbonate, sulfonate, chlorate and hydroxide, and n is either 1 or 2 and is equal to the valence of X.
Claim 2
Dependent Claim
138 words
In an alkali metal hypochlorite bleach solution containing a perfume oil to mask the chlorine odor thereof and a dispersant for said perfume oil, the improvement which comprises said dispersant being at least one quaternary ammonium compound having the structural formula ##STR2## where R 1 is an alkyl or aromatic group containing from about 1 to 20 carbon atoms, R 2 through R 7 are selected from the group consisting of alkyl and aromatic groups containing about 1 to 14 carbon atoms, cycloalkyl groups containing about 5 to 18 carbon atoms, alkaryl groups containing from 7 to 10 carbon atoms, and pyridyl groups and X is selected from the group consisting of fluoride, chloride, nitrate, sulfate, methyl sulfate, carbonate, sulfonate, chlorate and hydroxide, and n is either 1 or 2 and is equal to the valence of X.
Claim 3
Dependent Claim
35 words

Claim 4
Dependent Claim
14 words
The bleach solution of claim 2 wherein the alkali metal hypochlorite is sodium hypochlorite.
Claim 5
Dependent Claim
16 words
The bleach solution of claim 3 wherein the quaternary ammonium compound comprises hexadecyl trimethyl ammonium chloride.
Claim 6
Dependent Claim
16 words
The bleach solution of claim 3 wherein the quaternary ammonium compound comprises dodecyl trimethyl ammonium chloride.
