Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
92 words
A detergent composition comprising as a main detergent active ingredient a secondary amidoamino acid or its salts of the following formula (I): ##STR55## wherein R 1 represents an alkyl group, a hydroxyalkyl group, an aralkyl group or an alkenyl group each having from 7 to 23 carbon atoms, and X represents hydrogen, ammonium ion or a triethanolammonium ion; with the content of a water-soluble inorganic salt being 0.2 mol or less per 100 g of said secondary amidoamino acid, calculated as the acid type secondary amidoamino acid when the salts are used.
Claim 2
Dependent Claim
92 words
A detergent composition comprising as a main detergent active ingredient a secondary amidoamino acid or its salts of the following formula (I): ##STR55## wherein R 1 represents an alkyl group, a hydroxyalkyl group, an aralkyl group or an alkenyl group each having from 7 to 23 carbon atoms, and X represents hydrogen, ammonium ion or a triethanolammonium ion; with the content of a water-soluble inorganic salt being 0.2 mol or less per 100 g of said secondary amidoamino acid, calculated as the acid type secondary amidoamino acid when the salts are used.
Claim 3
Dependent Claim
90 words
A liquid detergent composition, comprising: from 1 to 45 wt% of a secondary amidoamino acid or its salts of the formula (I): ##STR56## wherein R 1 represents an alkyl group, a hydroxyalkyl group, an aralkyl group or an alkenyl group each having from 7 to 23 carbon atoms, and X represents hydrogen, ammonium ion or a triethanolammonium ion, and from 0.05 to 10 wt% of a water-soluble polymer which is insoluble in a concentrated salt solution; the composition having a water-soluble inorganic salt content of not larger than 1 wt%.
Claim 4
Dependent Claim
90 words
A liquid detergent composition, comprising: from 1 to 45 wt% of a secondary amidoamino acid or its salts of the formula (I): ##STR56## wherein R 1 represents an alkyl group, a hydroxyalkyl group, an aralkyl group or an alkenyl group each having from 7 to 23 carbon atoms, and X represents hydrogen, ammonium ion or a triethanolammonium ion, and from 0.05 to 10 wt% of a water-soluble polymer which is insoluble in a concentrated salt solution; the composition having a water-soluble inorganic salt content of not larger than 1 wt%.
Claim 5
Dependent Claim
161 words
A detergent composition, comprising: from 5 to 35 wt% of a secondary amidoamino acid or its salts of the following formula (I): ##STR57## wherein R 1 represents an alkyl group, a hydroxyalkyl group, an aralkyl group or an alkenyl group each having from 7 to 23 carbon atoms, and X represents hydrogen, ammonium ion or a triethanolammonium ion; with the content of a water-soluble inorganic salt being 0.2 mol or less per 100 g of said secondary amidoamino acid, calculated as the amidoamino acid when the salts are used, and from 1 to 17.5 wt% of an alkylamino acid-type surface active agent of the following formula (II): ##STR58## wherein R 2 represents a saturated or unsaturated hydrocarbon group having from 8 to 20 carbon atoms, R 3 represents a hydrogen atom or --CH 2 -- m --COOM in which m is a value of from 1 to 4, and M represents hydrogen, an alkali metal ion, ammonium ion or an alkanolamine.
