Description
Z~ HOE 89/H 019 he present invention relates to builders for'"'textile detergents for washing hea~y laundr~, whites and coloreds in automatic washing machines.
Suitable detergents for automatic washing machines comprise a combination of surfactants as the active detergents, bleaches, water glass, dispersants and the so-called builders which, on the one hand, fulfil the function of a skeletal substance and, on the other hand, by binding the hardness of the water, prevent encrusta-tions of inorganic and organic constituents on the material being washed and thus extend the life of the textiles and provide a pleasant feel on the skin when wearing these.
Suitable builders are alkali metal phosphates, above all sodium tripolyphosphate, zeolite A and alkali metal silicates, in particular a crystalline sodium layer silicate.
In certain regions, alkali metal phosphates are no longer added to the detergents, because of the risk of eutrophi-cation of slowly flowing water courses and lakes, even though precisely alkali metal phosphates have outstanding builder properties.
In US-A-4,274,975, a detergent composition is described in which, in particular, the zeolite of the formula Na12(AlO2 SiO2)1z x H20, in which x is an integer from about 20 to 30, is used as the builder.
A disadvantage in the use of a zeolite as the builder is the accelerated degradation of the bleach during tha storage time of the detergent and encrustation of the material being washed in the course of several washing steps by inorganic and organic constituents. The encrus-tations can be partially suppressed by a relatively high content of polycarboxylates in zeolite-containing .
2til7958 detergents. Instead, however, an undesirably high poly-carboxylate content in the effluent must be accepted. An increased polycarboxylate content has no influence on the degradation of the bleach.
In US-A-4,728,443, detergents are described in which crystalline layer silicic acids or alkali metal salts thereof of the formula N2Si~02~1 . y HaOr where x > 7.0, M
= Na, ~ or H ant y = 0 to 25, are incorporated as buil-ders. The disadvantage of these builders is the low Ca hardness-binding capacity, which does not adequately prevent encrustation of the material being washed with Ca salts. These builders have a very high Mg hardness-binding capacity.
It is the object of the invention to provide a builder, by means of whirh a textile detergent can be produced, of which the bleaching action is largely preserved during storage, which has an enhanced cleaning action and with which only slight encrustation on the material being washed takes place, with a small addition of polycarboxy-late.
The in~ention, by means of which, surprisingly, the stated object is achieved and the disadvantages described are avoided, relates to builders for textile detergents, which comprise a mixture of 20 to 80% by weight of a crystalline sodium layer silicate and 20 to 80% by weight of a zeolite.
Furthermore, the builders according to the invention for textile detergents can preferably and optionally have the features that a) the builder content in the textile detergent is 5 to 60% by weight, preferably 10 to 30% by weight, b) a crystalline sodium layer silicate having an SiO2/Na20 molar ratio of (1.9 to 3.5) : 1 is used, Z~}1'79~
c) a zeolite of the formula Nal2(Al02 . sia)l2 -x H2O, in which x is an integer from 20 to 30, is used, d) they are used at a primary particle size from 0.01 to 1000 ~m, in particular from 1 to 20 ~m, e) they are used together with up to 2.0% by weight of polycarboxylate, relative to the textile detergent, as a dispersant co-builder, f) they are used together with inorganic and/or organic phosphates and/or phosphonates, borates, citrates, gluconates, ethylenediaminetetraacetic acid, nitrilotriacetic acid and/or iminodiacetic acid or alkali metal salts thereof in quantities of up to 20~ by weight, relative to the textile detergent, and g) they are agglomerated together with the remaining ingredients of the textile detergent by the spray-mist mixing process by jetting-on of an aqueous binder, in particular water glass and/or a cellulose ether, in the range from 0.25 to 2.5 mm.
Suitable crystalline sodium layer silicates have an ion exchange capacity of more than 100 mmol of Na~/100 g of anhydrous substance and can be selected from naturally occurring alkali metal silicates such as natrosilite (Na2Si2O5) or revdite (Na2Si2O5 . SH2O). In general, how-ever, syntheti~ally produced layer silicates are prefer-: red, in particular those which are obtained in accordance with EP-A-0,293,640.
Suitable zeolites have an ion exchange capacity of more than 100 mmol of Naf/100 g of anhydrous ~ubstance, ~uch as, for example, naturally occurring chabasite (CatAl2Si~0~2~ . 6 H20), the calcium content of which has been xchanged for sodium.
In general, however, synthetically produced zeolites are preferred, in particular those obtained in accordance .. ~ .' ,.'' :
.
' Zl~1'7'358 with US-A-4,274,975. --The layer silicate and the zeolite as builder mixturesexert a synergistic effect, by means of which, on the one hand, the decomposition of the bleach during storage of detergent formulations based thereon is greatly retarded and, on the other hand, enc Nstation of the material being washed with calcium and magnesium salts is effec-tively prevented.
The surfactants which have proved suitable in the textile detergent according to the invention are carboxylates (soaps), alkanesulfonates, laurylbenzenesulfonate, dodecylbenzenesulfonate, alkylphenol polyglycol ethers or the condensation product of polypropylene glycol with 8 mol of ethylene oxide.
Suitable bleaches are sodium perborate tetrahydrate (NaBO3 . 4 H2O), sodium perborate monohydrate (NaBO3 . H2~) or sodium percarbonate (2 Na2CO3 . 3 H2O2).
Textile detergents with the builder according to the invention are equally suitable for any water hardness, depending on the dosage, on the assumption that the total hardness consists to the extent of 70 to 85% of Ca hardness and to the extent of 30 to 15% of Ng hardness.
The primary washing effect of the textile detergent was determined at 60C on various test fabrics (EMPA tSwiss Materials Testing Institute] Standard lO1 Cotton; ENPA
Standard 104 2 : 1 polyester/cotton, C-WF~ Standard 10 cotton, C-WFR Standard 20 2 : 1 polyester~cotton) accord-ing to DIN 44983, Sheet 1 (January 1968) Section 4.1, by determining the differential reflection which results from the difference of the reflection of the test fabric before and after the wash.
The secondary washing effect was determined at 90C on various test fabrics (EMPA Standard 101 cotton, cotton ... .
2~}1~7~S8 _ 5 _ terry fabric) according to DIN 44983 (4.4). ..
The total hardness of the washing water was 18 German hardness (hardness range III). The CaO: MqO ratio varied between 2 : 1 and 5 : 1.
In the washing tests, 115 g of detergent were added in the pre-wash, and 135 g of detergent in the main wash.
The invention is further illustrated by the examples which follow.
Examples 1 to 9.
The detergent formulations were prepared from the indi-vidual components given below by the spray-mist mixing process familiar to those skilled in the art (Table 1).
