Abstract
Abstract A method to make and a base mix fabric softener composition of a concentrate remaining substantially pumpable after transportation and on standing, said concentrate comprising: (a) between 80 to 20% by weight of at least one quaternary ammonium compound having the formula: ##STR1## wherein R 1 and R 2 are each independently selected from the class consisting of alkyl and alkenyl groups having 12 to 20 carbon atoms, and R 3 and R 4 are each independently selected from the class consisting of C 1 to C 3 alkyl, (C n H 2n O)H x where n=2 or 3 and x is from 1 to 3, and (b) between 20 to 80% by weight of at least one alkyl substitute imidazolinium compound having the general formula: ##STR2## wherein R 1 and R 2 are each independently selected from the class consisting of alkyl and alkenyl groups having 12 to 20 carbon atoms, and X is Cl - or CH 3 SO 4 said concentrate of (a) and (b) being dissolved in a member selected from the class consisting of at least one alcohol, or of a mixture of at least one alcohol and water, said at least one alcohol having a low alkyl chain of 1 to 3 carbon atoms.

Claim 1
Independent Claim
253 words
A base mix fabric softener composition of a concentrate remaining substantially pumpable after transportation and on standing, said concentrate comprising: (a) between 80 to 20% by weight of at least one quaternary ammonium compound having the formula: ##STR8## wherein R 1 and R 2 are each independently selected from the class consisting of alkyl and alkanyl groups having 12 to 20 carbon atoms, and R 3 and R 4 are each independently selected from the class consisting of C 1 to C 3 alkyl, (C n --H 2n O)H x , where n is an integer selected from 2 and 3 and x is an integer selected from 1, 2 and 3 (b) between 20 to 80% by weight of at least one alkyl substitute imidazolinium compound having the general formula: ##STR9## wherein R 1 and R 2 are each independently selected from the class consisting of alkyl and alkenyl groups having 12 to 20 carbon atoms and where X - is a member selected from the class consisting of the ion chloride, and the ion methyl sulfate, said concentrate of (a) and (b) being dissolved in a member selected from the class consisting of at least one alcohol, or of a mixture of at least one alcohol and water, said at least one alcohol having a low alkyl chain of 1 to 3 carbon atoms, and wherein said (a) and (b) represent between 60 to 80% by weight, based upon the total weight of the base mix, thereby producing a super concentrate.
Claim 2
Dependent Claim
253 words
A base mix fabric softener composition of a concentrate remaining substantially pumpable after transportation and on standing, said concentrate comprising: (a) between 80 to 20% by weight of at least one quaternary ammonium compound having the formula: ##STR8## wherein R 1 and R 2 are each independently selected from the class consisting of alkyl and alkanyl groups having 12 to 20 carbon atoms, and R 3 and R 4 are each independently selected from the class consisting of C 1 to C 3 alkyl, (C n --H 2n O)H x , where n is an integer selected from 2 and 3 and x is an integer selected from 1, 2 and 3 (b) between 20 to 80% by weight of at least one alkyl substitute imidazolinium compound having the general formula: ##STR9## wherein R 1 and R 2 are each independently selected from the class consisting of alkyl and alkenyl groups having 12 to 20 carbon atoms and where X - is a member selected from the class consisting of the ion chloride, and the ion methyl sulfate, said concentrate of (a) and (b) being dissolved in a member selected from the class consisting of at least one alcohol, or of a mixture of at least one alcohol and water, said at least one alcohol having a low alkyl chain of 1 to 3 carbon atoms, and wherein said (a) and (b) represent between 60 to 80% by weight, based upon the total weight of the base mix, thereby producing a super concentrate.
Claim 3
Dependent Claim
58 words
The base mix as defined in claim 1 wherein said R 1 and R 2 as defined in paragraph (a) for the quaternary ammonium compound, and as defined in paragraph (b) imidazolinium compound are each independently selected from alkyl and alkenyl groups having between 16 and 20 carbon atoms and having an average value of 18 carbon atoms.
Claim 4
Dependent Claim
28 words
The base mix as defined in claim 1, wherein said diluent is isopropanol and water, said isopropanol is at least 1/3 to 1/2 by weight of said diluent.
Claim 5
Dependent Claim
58 words
The base mix as defined in claim 1, wherein said (a) and (b) represent at least 74%, said diluent is isopropanol end water, said isopropanol is at least 20 to 5%, said water is about 5 to 12.5% and said, % being by weight based upon the total weight of the base mix, thereby producing a super concentrate.
Claim 6
Dependent Claim
109 words
A method of preparing a base mix fabric composition of a concentrate as defined in claim 1 comprising: (a) mixing: between 80 to 20% by weight of at least one dialkyl amine and 20 to 80% by weight of at least an imidazoline derived from fatty acids and diethylene triamine, to form a blend of amines, (b) reacting under pressure, said blend of amines from step (a) in the presence of chloromethane and a mixture of alcohol and water, said alcohol having a low alkyl chain of 1 to 3 carbon atoms to quaternize the amines into at least one imidazolinium compound and at least one quaternary ammonium compounds.
