Abstract

The invention relates to a care product for automatic dishwashers, which is effective against fat deposits in an automatic dishwasher, and includes at least one fatty alcohol of the formula R 1 —O-(EO) m —H as defined here. The invention further relates to the use of said care product for cleaning and/or care of an automatic dishwasher, and to a method for cleaning and/or care of a dishwasher using said care product.

First claim

What is claimed is:

1 . A method for cleaning and/or care of an automatic dishwasher, comprising placing an amount of a care product for automatic dishwashers in the automatic dishwasher; and running the automatic dishwasher,
wherein the care product includes at least one fatty alcohol ethoxylate of the formula (I)
R 1 —O-(EO) m —H  (I)

where R 1 is a linear or branched, substituted or unsubstituted alkyl group having 16 to 18 C atoms; EO is an ethylene oxide unit; and m is 20 to 30, preferably 22 to 27, in particular 25; wherein the fatty alcohol ethoxylate of the formula (I) is included in an amount of 1 to 18% by weight, based on the care product, and the absolute amount of the at least one fatty alcohol ethoxylate of the formula (I) in the care product is 0.1 to 4 g/run or job.

2 . The method according to claim 1 , wherein the fatty alcohol ethoxylate of formula (I) is included in an amount of preferably 6 to 13% by weight based on the total weight of the care product.

3 . The method according to claim 1 , wherein the amount of the at least one fatty alcohol ethoxylate of formula (I) comprises 1 to 3 g/run or job.

4 . The method according to claim 1 , wherein the care product includes further at least one fatty alcohol alkoxylate of the formula (II)
R 2 -(AO) w —R 3   (II),
where R 2 stands for a linear or branched, substituted or unsubstituted alkyl group having 10 to 16 C atoms; R 3 stands for H or a linear or branched hydrocarbon group having 2 to 26 carbon atoms; each A independently stands for a member from the group comprising —CH 2 CH 2 — and —CH 2 —CH(CH 3 )—, CH 2 —CH 2 —CH 2 —, CH 2 —CH 2 —CH 2 —CH 2 —, —CH 2 —CH(CH 2 —CH 3 )—, —CH 2 —C(CH 3 ) 2 —, or —CH 2 —CH 2 —CH(CH 3 )—, wherein at least one A is —CH 2 CH 2 — and at least one A is —CH 2 —CH(CH 3 )—, CH 2 —CH 2 —CH 2 —, CH 2 —CH 2 —CH 2 —CH 2 —, —CH 2 —CH(CH 2 —CH 3 )—, —CH 2 —C(CH 3 ) 2 —, or —CH 2 —CH 2 —CH(CH 3 )—; and w stands for an integer from 2 to 50, wherein the fatty alcohol alkoxylate of the formula (II) is included optionally in an amount of 0.01 to 3% by weight, and/or the absolute amount of the fatty alcohol alkoxylate of the formula (II) in the care product is optionally 0.001 to 3 g/job, and/or optionally the weight ratio of the fatty alcohol ethoxylate of the formula (I) and the fatty alcohol alkoxylate of the formula (II) in the care product is 20:1 to 1:1.

5 . A care product for automatic dishwashers including a fatty alcohol ethoxylate of the formula (I)
R 1 —O-(EO) m —H  (I),
where R 1 is a linear or branched, substituted or unsubstituted alkyl group having 16 to 18 C atoms; EO is an ethylene oxide unit; and m is 20 to 30, preferably 22 to 27, in particular 25;
wherein the fatty alcohol ethoxylate of the formula (I) is included in an amount of 1 to 18% by weight, based on the care product, and the absolute amount of the at least one fatty alcohol ethoxylate of the formula (I) in the care product is 0.1 to 4 g/job, preferably 1 to 3 g/job, particularly preferably 1.5 to 2.5 g/job, for example, 2 g/job.

6 . The care product according to claim 5 , wherein the fatty alcohol ethoxylate of formula (I) comprises 6 to 13% by weight based on the care product.

7 . The care product according to claim 5 , wherein the fatty alcohol ethoxylate of formula (I) comprises 9 to 10% by weight by weight based on the care product.

8 . The care product according to claim 5 , wherein the care product includes further at least one fatty alcohol alkoxylate of the formula (II)
R 2 -(AO) w —R 3   (II),
where R 2 stands for a linear or branched, substituted or unsubstituted alkyl group having 10 to 16 C atoms; R 3 stands for H or a linear or branched hydrocarbon group having 2 to 26 carbon atoms; each A independently stands for a member from the group comprising —CH 2 CH 2 — and —CH 2 —CH(CH 3 )—, CH 2 —CH 2 —CH 2 —, CH 2 —CH 2 —CH 2 —CH 2 —, —CH 2 —CH(CH 2 —CH 3 )—, —CH 2 —C(CH 3 ) 2 —, or —CH 2 —CH 2 —CH(CH 3 )—, wherein at least one A is —CH 2 CH 2 — and at least one A is —CH 2 —CH(CH 3 )—, CH 2 —CH 2 —CH 2 —, CH 2 —CH 2 —CH 2 —CH 2 —, —CH 2 —CH(CH 2 —CH 3 )—, —CH 2 —C(CH 3 ) 2 —, or —CH 2 —CH 2 —CH(CH 3 )—; and w stands for an integer from 2 to 50, preferably 10 to 30, wherein the fatty alcohol alkoxylate of the formula (II) is included optionally in an amount of 0.01 to 3% by weight based on the care product, and/or the absolute amount of the fatty alcohol alkoxylate of the formula (II) in the care product is optionally 0.001 to 3 g/job, and/or optionally the weight ratio of the fatty alcohol ethoxylate of the formula (I) and the fatty alcohol alkoxylate of the formula (II) in the care product is 20:1 to 1:1.

9 . The care-product according to claim 1 , wherein the care product/composition is phosphate-free and/or phosphonate-free.

10 . The care-product according to claim 1 , wherein the care product/composition
(a) is present in solid form; and/or (b) is present in preproportioned form; and/or (c) is located in a water-insoluble, water-soluble, or water-dispersible packaging, in particular in a polyvinyl alcohol-containing film.

11 . The care-product according to claim 1 , wherein the care product further comprises at least one component selected from the group consisting of builders, further surfactants, polymers, enzymes, corrosion inhibitors, glass corrosion inhibitors, disintegration aids, fragrances, and perfume carriers.
