WASHING COMPOSITIONS CONTAINING ALUMINOSILICATES AND NONIONICS AND METHOD OF WASHING TEXTILES

摘要

The composition contains silicates which are able to bind the hardness formers in the water and have the formula (cat2/nO)xMe2O3.(SiO2)y in which cat is a cation which can exchange with calcium and has n charges, x is a number from 0.7 to 1.5, Me is boron or aluminium, y is a number from 0.8 to 6, and which have a calcium-binding capacity of at least 50 mg of CaO/g of anhydrous silicate. These silicates may contain bound water. The composition furthermore contains a surfactant component comprising 1 part by weight of non-ionic and 0-3 parts by weight of anionic surfactants, where the non-ionic surfactants represent a mixture of various highly ethoxylated 8-20 which have an aliphatic hydrocarbon radical with 10-18 C atoms and in which 0.2-2 parts by weight of non-ionic compounds with 2-6 ethylene glycol ether residues are present in the molecule per part by weight of non-ionic compounds with 8-29 ethylene glycol ether residues in the molecule. The aqueous wash liquor contains compositions of this type. The water-insoluble silicates are in finely divided form in this treatment liquor. The washing process brings about - even in the complete absence of phosphorus - a good removal in particular of greasy and oily soiling on textiles.
