Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
199 words
A stable aqueous dispersion comprising: (a) from 1% to 4% of an amine or mixture of amines selected from the group consisting of the di(higher alkyl) cyclic amines of the formula: ##STR6## wherein n is 2, 3 or 4, R 1 and R 2 are, independently, a C 8 -C 30 alkyl or alkenyl radical, or mixtures of such radicals; Q is CH, CH 2 , NH or N, X is ##STR7## wherein T is NR 5 , R 5 being H or C 1 -C 4 alkyl, and R 4 is a divalent C 1 -C 3 alkylene group or (C 2 H 4 O) m , wherein m is a number of from 1 to 8; or X is R 4 ; and (b) a compound selected from the group of conventional quaternary ammonium softening agents having two higher alkyl groups, each comprising from 8 to 30 carbon atoms; and (c) from about 1% to about 50% by weight of the amine of a dispersing aid which is a Bronstedt acid having a pKa value of not greater than 6, the amount of said acid being such that the pH of the composition is 5 or less.
Claim 2
Dependent Claim
199 words
A stable aqueous dispersion comprising: (a) from 1% to 4% of an amine or mixture of amines selected from the group consisting of the di(higher alkyl) cyclic amines of the formula: ##STR6## wherein n is 2, 3 or 4, R 1 and R 2 are, independently, a C 8 -C 30 alkyl or alkenyl radical, or mixtures of such radicals; Q is CH, CH 2 , NH or N, X is ##STR7## wherein T is NR 5 , R 5 being H or C 1 -C 4 alkyl, and R 4 is a divalent C 1 -C 3 alkylene group or (C 2 H 4 O) m , wherein m is a number of from 1 to 8; or X is R 4 ; and (b) a compound selected from the group of conventional quaternary ammonium softening agents having two higher alkyl groups, each comprising from 8 to 30 carbon atoms; and (c) from about 1% to about 50% by weight of the amine of a dispersing aid which is a Bronstedt acid having a pKa value of not greater than 6, the amount of said acid being such that the pH of the composition is 5 or less.
Claim 3
Dependent Claim
19 words
A dispersion according to claim 1 wherein the weight ratio (a):(b) is in the range from 3:1 to 1:3.
Claim 4
Dependent Claim
15 words
A dispersion according to claim 2 which comprises from 2% to 35% of the amine.
Claim 5
Dependent Claim
29 words
A dispersion according to claim 3 wherein the amine is a 1-(higher alkyl) amidoethyl-2-(higher alkyl) imidazoline, wherein higher alkyl represents an alkyl having from 11 to 22 carbon atoms.
Claim 6
Dependent Claim
43 words
A dispersion according to claim 4 wherein b. is selected from the 1-(lower alkyl)-1-(higher alkyl) amidoethyl-2-(higher alkyl) imidazolinium compounds, wherein lower alkyl represents alkyl having from 1 to 4 carbon atoms, and higher alkyl represents alkyl having from 11 to 22 carbon atoms.
Claim 7
Dependent Claim
92 words
A dispersion according to any one of the preceding claims which further comprises an emulsion of predominently linear di(C 1 -C 5 ) alkyl or C 1 -C 5 alkylaryl siloxane in which the alkyl groups may be partially or wholly fluorinated and which may be substituted with cationic nitrogen groups, the siloxane having a viscosity at 25° C. of at least 100 centistokes and up to 100000 centistokes; the weight ratio of the siloxane content of the emulsion to the amine component being in the range of from 5:1 to 1:100.
Claim 8
Dependent Claim
13 words
A dispersion according to claim 6 wherein the siloxane is a polydimethyl siloxane.
Claim 9
Dependent Claim
31 words
A dispersion according to claim 6 which further comprises from 0.5% to 10% of a nonionic compound selected from the group consisting of glycerol esters, fatty alcohols and alkoxylated fatty alcohols.
