Low-foam rinsing and washing agents for dish washers

Claim 2

The low-foaming rinsing and washing compositions of claim 1 wherein said component B is a polyoxypropylene glycol having an average number of oxypropylene units of between 29 and 70, adducted with from 0 to 30 mol percent of oxyethylene units, the total amount of oxypropylene and oxyethylene units in said adduct being 100 mol percent.

Claim 3

The low-foaming rinsing and washing composition of claim 1 wherein said component B is a propylene oxide adduct of a hydrocarbon compound having from two to 10 carbon atoms and at least two reactive hydrogen atoms selected from the group consisting of alkanes, benzene and alkylbenzenes, substituted with substitutents selected from the group consisting of hydroxy, amino, and mixtures thereof, said propylene oxide adduct having an average number of oxypropylene units of between 27 and 68, adducted with from 0 to 30 mol percent of oxyethylene units, the total number of oxypropylene and oxyeThylene units in said adduct being 100 mol percent.

Claim 4

The low-foaming rinsing and washing compositions of claim 1 wherein said component B is an alkylene oxide adduct of a high molecular weight lipophilic radical of the formula: R-Y-H wherein R represents a radical having from eight to 36 carbon atoms selected from the group consisting of alkyl, alkenyl, alkadienyl, monohydroxyalkenyl and alkylphenyl and Y represents a bridging link selected from the group consisting of O, S, COO, NH, CONH, and SO2NH: adducted first with oxyethylene units and thereafter with oxyalkylene units selected from the group consisting of oxypropylene and oxybutylene, said oxyethylene being from 0 to 70 mol percent of the total amount of oxyalkylene units present; from 2 to 90 oxypropylene and oxybutylene units being present in said adduct.

Claim 5

The low-foaming rinsing and washing compositions of claim 5 wherein said alkylene oxide adduct is the addition product of from 2 to 30 mols of propylene oxide to an alcohol having from eight to 22 carbon atoms selected from the group consisting of fatty alcohols and alkylphenols.

Claim 6

The low-foaming rinsing and washing composition of claim 5 wherein said alkylene oxide adduct is the addition product of from 2 to 20 mols of ethylene oxide and from 2 to 30 mols of propylene oxide, to an alcohol having from eight to 22 carbon atoms selected from the group consisting of fatty alcohols and alkylphenols, wherein at least 30 mol percent of said alkylene oxides is propylene oxide.

Claim 7

The low-foaming rinsing and washing compositions of claim 1 wherein said component A is present in an amount of from 85 percent to 98 percent by weight and said component B is present in an amount of from 2 percent to 15 percent by weight.

Claim 8

Aqueous concentrates containing from 10 percent to 30 percent by weight of the low-foaming rinsing and washing compositions of claim 1.

Claim 9

The method of washing and rinsing solid articles which comprises forcefully contacting said solid articles with water containing from 0.01 to 0.5 grams per liter of the low-foaming rinsing and washing compositions of claim 1.
