Abstract

An agent is provided which is to be used in the treatment of textiles, containing: i) at least one anionic, aromatic polyester, containing at least one structural unit of formula (I), at least one structural unit of formula (II) and at least one structural unit of formula (III) as described herein, and ii) at least one non-ionic, aromatic polyester containing at least one structural unit of formula (IV) and at least one structural unit of formula (V) as described herein, and iii) at least one surfactant. The agent has an excellent primary washing force and can be, in particular, more storage stable than single doses in a multi-chamber bag.

First claim

The invention claimed is:

1. A portion comprising an agent for use in the treatment of textiles, wherein the agent comprises:
(i) at least one anionic, aromatic polyester, containing at least one structural unit of formula (I), at least one structural unit of formula (II), and at least one structural unit of formula (III)

in which
a, b and c, independently of one another, each stand for a number from 1 to 200,
1/n M n+ stands for an equivalent of a cation having the valence n, with n =1, 2 or 3,
R 1 , R 2 , R 3 , R 4 , R 5 and R 6 , independently of one another, each stand for hydrogen, a C 1 -C 18 -n-alkyl group, or a C 3 -C 18 -iso-alkyl group,
R 7 stands for a linear or branched C 1 -C 30 alkyl group, for a linear or branched C 2 -C 30 alkenyl group, for a cycloalkyl group having 5 to 9 carbon atoms, for a C 6 -C 30 aryl group, or for a C 6 -C 30 arylalkyl group,

(ii) at least one non-ionic, aromatic polyester, containing at least one structural unit of formula (IV) and at least one structural unit of formula (V)

in which
h and i, independently of one another, each stand for a number from 1 to 200,

R 8 , R 9 , R 10 and R 11 , independently of one another, each stand for hydrogen, a C 1 -C 18 -n-alkyl group, or -iso-alkyl group,
R 12 stands for a linear or branched C 1 -C 30 alkyl group, for a linear or branched C 2 -C 30 alkenyl group, for a cycloalkyl group having 5 to 9 carbon atoms, for a C 6 -C 30 aryl group, or for a C 6 -C 30 arylalkyl group,
and
(iii) at least one surfactant,
wherein the agent is separated into at least two compositions in the portion, wherein one of the compositions is a solid composition and a further of the compositions is a liquid composition.

2. The portion according to claim 1 , wherein the total amount of said anionic, aromatic polyester has a number average of 1 to 50 structural units of formula (I) and 1 to 50 structural units of formula (II).

3. The portion according to claim 1 , wherein the total amount of said anionic, aromatic polyester has, as a number average, between 1 and 25 structural units of formula (I), between 1 and 30 structural units of formula (II), and between 0.05 and 15 structural units of formula (III).

4. The portion according to claim 1 , wherein, in formulas (I), (II) and (II) of the anionic, aromatic polyester, R 1 , R 2 , R 3 , R 4 , R 5 and R 6 , independently of one another, each stand for hydrogen or methyl.

5. The portion according to claim 1 , wherein, in formulas (I), (II), and (III) of the anionic, aromatic polyester, a, b, and c, independently of one another, each stand for a number from 1 to 20.

6. The portion according to claim 1 , wherein said anionic, aromatic polyesters are solid and have softening points above 40° C.

7. The portion according to claim 1 , wherein, in relation to the total weight of the agent, said anionic, aromatic polyesters are contained in a total amount of from 0.5 to 8.0% by weight.

8. The portion according to claim 1 , wherein, in accordance with formulas (IV) and (V) of the non-ionic, aromatic polyester, R 8 , R 9 , R 10 and R 11 , independently of one another, each stand for hydrogen or methyl.

9. The portion according to claim 1 , wherein R 12 , in accordance with formula (V) of the non-ionic, aromatic polyester, stands for methyl.

10. The portion according to claim 1 , wherein h and i, independently of one another, each stand for a number from 1 to 20.

11. The portion according to claim 1 , wherein the total amount of said non-ionic, aromatic polyester includes, as a number average, between 1 and 25 structural units of formula (IV), and between 0.05 and 15 structural units of formula (V).

12. The portion according to claim 1 , wherein, in relation to the total weight of the agent, said non-ionic, aromatic polyesters are contained in a total amount of from 0.5 to 8.0% by weight.

13. The portion according to claim 1 , wherein the at least one surfactant (iii) comprises at least one anionic surfactant and at least one non-ionic surfactant.

14. The portion according to claim 1 , wherein a total amount of surfactants (iii) are present in a total amount of from about 40 to about 70% by weight.

15. The portion according to claim 1 comprising at least two chambers having walls formed from water-soluble material, wherein,
(i) at least one of the chambers comprises the solid composition and wherein the solid composition comprises the at least one anionic, aromatic polyester (i), and
(ii) at least one further of the chambers contains the liquid composition and wherein the liquid composition comprises the at least one non-ionic, aromatic polyester,
wherein the portion further comprises the at least one surfactant (iii).

16. The portion according to claim 15 , wherein the total amount of surfactant (iii) in the liquid composition of the portion is up to about 85% by weight based on the total weight of the liquid composition of the portion.

17. The portion according to claim 1 , wherein the total amount of said anionic, aromatic polyester has, as a number average, between 1 and 5 structural units of formula (I), between 3 and 10 structural units of formula (II), and between 0.25 and 3 structural units of formula (III).

18. The portion according to claim 1 , wherein, in formulas (I), (II), and (III) of the anionic, aromatic polyester, a, b, and c, independently of one another, each stand for a number from 1 to 5, and wherein h and i, independently of one another, each stand for a number from 1 to 20.
