Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
186 words
A low irritating liquid detergent composition wherein the active ingredients consist essentially of: (a) from about 1 to 15% by weight of the total composition of a sulfobetaine of the formula ##STR4## wherein R is an alkyl group of from 8 to 18 carbon atoms or mixtures thereof, R' is OH or H, x is an integer from 1 to 3 and M is selected from the group consisting of alkali metals, alkaline earth metals and alkanol amine salts selected from the group consisting of mono-, di- and triethanolamine salts; and (b) from about 1 to 15% by weight of the total composition of an anionic detergent of the formula R"--O--(C.sub.2 H.sub.4 O).sub.x --SO.sub.3 M wherein R" is a branched or straight chain saturated or unsaturated hydrocarbon radical, alkylaromatic hydrocarbon radical or alkylaryl hydrocarbon radical containing from 6 to 20 carbon atoms, x is an integer from 1 to 5 and M is selected from the group consisting of alkali metals, alkaline earth metals and alkanol amine salts; wherein the total of (a) and (b) does not exceed about 20% by weight of the total composition.
Claim 2
Dependent Claim
186 words
A low irritating liquid detergent composition wherein the active ingredients consist essentially of: (a) from about 1 to 15% by weight of the total composition of a sulfobetaine of the formula ##STR4## wherein R is an alkyl group of from 8 to 18 carbon atoms or mixtures thereof, R' is OH or H, x is an integer from 1 to 3 and M is selected from the group consisting of alkali metals, alkaline earth metals and alkanol amine salts selected from the group consisting of mono-, di- and triethanolamine salts; and (b) from about 1 to 15% by weight of the total composition of an anionic detergent of the formula R"--O--(C.sub.2 H.sub.4 O).sub.x --SO.sub.3 M wherein R" is a branched or straight chain saturated or unsaturated hydrocarbon radical, alkylaromatic hydrocarbon radical or alkylaryl hydrocarbon radical containing from 6 to 20 carbon atoms, x is an integer from 1 to 5 and M is selected from the group consisting of alkali metals, alkaline earth metals and alkanol amine salts; wherein the total of (a) and (b) does not exceed about 20% by weight of the total composition.
Claim 3
Dependent Claim
