Abstract

A fabric softener composition comprising: a. 1 to 20 wt. % ionic compound of general formula I: (I) wherein b. 0.1 to 20 wt. % fatty co-softener; and c. Water.

First claim

The invention claimed is:

1 . A fabric softener composition comprising:
a. 1 to 20 wt. % ionic compound of general formula I:

wherein
A is a tetravalent linker selected from the group consisting of A-1 to A-6

Q 1 to Q 4 , which may be identical or different from each other, are selected from the group consisting of hydrogen, R and X, and W is an anion or an anionic group bearing w negative charges and r is the number of substituents Q 1 to Q 4 which are represented by a group X,
wherein R, which may be the same or different at each occurrence, is a C 5 -C 27 aliphatic group,
m, m′, m″ and m′″, which may be the same or different at each occurrence, are 0, 1, 2 or 3,
k, k′, k″, k′″ and k″″, which may be the same or different, are 0, 1, 2 or 3, and X, which may be the same or different at each occurrence, is represented by formula II

wherein Z 1 , Z 2 and Z 3 , are O, Y is a divalent C 1 -C 6 aliphatic radical,
R′, R″ and R′″, which may be the same or different, are hydrogen or a C 1 to C 4 alkyl group,
the sum of n+n′ being 2,
wherein at least one of Q 1 to Q 4 is represented by X and at least two of groups Q 1 to Q 4 are represented by R, which groups R may be the same or different at each occurrence, and
wherein, if the ionic compound is such that (i) A is represented by A-6 with m, in, m′″ and m′″ equal to 0, (ii) one and only one of Q 1 to Q 4 is represented by a substituent X and n in the substituent X is equal to 0 and (iii) two and only two of Q 1 to Q 4 are represented by substituents R, then the difference of the number of carbon atoms of the two substituents R is 0, 1, 3 or more than 3,
b. 0.1 to 20 wt, % fatty co-softener; and
c. water.

2 . The fabric softener composition according to claim 1 wherein the ionic compound comprises one or two groups X and two and only two groups R.

3 . The fabric softener composition according to claim 1 wherein the n′ of the ionic compound is 1 and the Y of the ionic compound is a C 2 -C 6 aliphatic group.

4 . The fabric softener composition according to claim 1 wherein the A of the ionic compound is represented by A-6, m, m′, m″ and m′″ are 0, Z 1 to Z 3 are 0 and wherein the ionic compound comprises two groups R and one group X.

5 . The fabric softener composition according to claim 1 wherein the A of the ionic compound is represented by A-3 or A-4, m, m′, m″, m′″ and k′″ are 0 and two of substituents Q 1 to Q 4 are represented by groups X with both X attached to the same carbon atom of linker A and two groups R attached to the same or to different carbon atoms of linker A.

6 . The fabric softener composition according to claim 1 wherein the A of the ionic compound represented by A-1, m and m′ are 1, m″ and m′ are 0, k is 0 and two substituents Q 1 to Q 4 are represented by groups X with both groups X being attached to the nitrogen atom of linker A.

7 . The fabric softener composition according to claim 1 wherein the A of the ionic compound represented by A-2, k″ is 0, k″ is 1, m is 1, m′, m″ and m′″ are 0 and two of substituents Q 1 to Q 4 are represented by groups X attached to the same carbon atom of linker A.

8 . The fabric softener composition according to claim 1 wherein the A of the ionic compound represented by A-5, m, m′, m″, m′″ and k″″ are 0, two of substituents Q 1 to Q 4 are X with each carbon atom of linker A carrying one group X and one group R wherein X and R might be the same or different at each occurrence.

9 . The fabric softener composition according to claim 1 , wherein the fatty co-softener is selected from fatty esters, fatty acids, fatty alcohols and combinations thereof.

10 . The fabric softener composition according to claim 1 wherein the fabric softener comprises dye, antifoam and/or preservative.

11 . A fabric softener composition comprising:
a. 1 to 20 wt. % ionic compound of general formula I:

wherein
A is a tetravalent linker selected from the group consisting of A-1 to A-6

Q 1 to Q 4 , which may be identical or different from each other, are selected from the group consisting of hydrogen, R and X, and W is an anion or an anionic group bearing w negative charges and r is the number of substituents Q 1 to Q 4 which are represented by a group X,
wherein R, which may be the same or different at each occurrence, is a C 5 -C 27 aliphatic group,
m, m′, m″ and m′″, which may be the same or different at each occurrence, are 0, 1, 2 or 3,
k, k′k″, k′″ and k″″, which may be the same or different, are 0, 1, 2 or 3, and X, which may be the same or different at each occurrence, is represented by formula II

wherein Z 1 , Z 2 and Z 3 , are O, Y is are CH 2 ,
R′, R″ and R′″, which may be the same or different, are hydrogen or a C 1 to C 4 alkyl group,
n is 1, n′ is 0,
wherein at least one of Q 1 to Q 4 is represented by X and at least two of groups Q 1 to Q 4 are represented by R, which groups R may be the same or different at each occurrence, and
wherein, if the ionic compound is such that (i) A is represented by A-6 with m, in, m′″ and m′″ equal to 0, (ii) one and only one of Q 1 to Q 4 is represented by a substituent X and n in the substituent X is equal to 0 and (iii) two and only two of Q 1 to Q 4 are represented by substituents R, then the difference of the number of carbon atoms of the two substituents R is 0, 1, 3 or more than 3,
