Description

A builder for an alkaline detergent
The invention relates to a builder component for an alka¬ line, water-based detergent, the function of the builder component being to bind into a complex the polyvalent metal ions present in the washing water form and to act as a deflocculant and dispersant of the aggregates formed by the dirt particles detached in the wash and the tenside present in the detergent.
In the terminology of the art, the builder components of detergents are called builders.
In water-based detergents - both in textile detergents and in industrial detergent solutions - the ability to form complexes and the ability to disperse small particles in alkaline conditions are indispensable properties..
The complexing of metal ions in a washing solution is in¬ dispensable, because polyvalent metal ions prevent the formation of insoluble, flocculated particle aggregates with the dirt-dissolving surface active agents of deter¬ gents, so-called tensides, and the dirt detached by them. The water used for washing is often hard, i.e. it has a high content of calcium ions which must be bound to com¬ plexes.
The dispersing property, for its part, prevents the re- deposition of detached dirt on the surface being washed, also preventing, but by another chemical mechanism, the flocculation of dirt particles into larger, precipitating aggregates, thereby keeping the particles in solution.
The builders used in known alkaline detergents are synthe¬ tically formed alkali salts of polyphosphates, such as sodium tripolyphosphate, STPP, and tetrapotassium tripoly- phosphate, TKPP, or aminopolycarboxylic acids or their alkali salts, such as nitrilo triacetate, NTA, or ethylene diamine tetra-acetate, EDTA. In addition to these, certain sodium aluminum silicates can be used as builders.
The disadvantage of known builders is the damage caused by them, or suspected damage, in the environment when they pass mainly into watercourses along with washing waters.
Polyphosphates contain large amounts of phosphorus, which is a nutrient for biochemical growth and thereby speeds up biochemical activity, accelerating the eutrophication of watercourses.
Owing to their structure and chemical stability, aminopoly- carboxylic acids, for their part, decompose biochemically very slowly in nature and thereby cause bioaccumulation. Their effect on the natural ecosystem is not known pre¬ cisely, but it is suspected that they are mutagenic and possibly carcinogenic.
The use of silicates, for its part, is limited by their weak performance in washing detergents. The dispersing capacity of silicates is not considerable, and therefore they cannot be used alone as builders. Silicates do not constitute a considerable environmental hazard.
Knowledge or suspicions of the detrimental effects of con¬ ventional builders on nature has brought to the fore the aim to prohibit their use and a need to replace them with products biochemically more advantageous.
Substitutes have been found to a limited extent for conven¬ tional builders. The use of, for example, lactic acid, gluconic acid and sodium gluconate, sodium glucoheptonate and citric acid is known in these applications. The princi¬ pal advantage of these products is that they are not detri¬ mental to the environment, but their use as builders is limited by economic factors. The price of the products in question as compared to their performance as builders is uneconomical.
The object of the invention is to provide a builder for an alkaline, water-based detergent, a builder which can en¬ tirely or in part replace the conventional builders, detri¬ mental to the environment, and which constitutes a lesser biochemical hazard to the environment than do conventional polyphosphates containing phosphorus nutrient and amino¬ polycarboxylic acids which decompose slowly in nature and are biochemically suspect.
These objects have been achieved in a very satisfactory manner with the present invention, the main characteristics of which are given in the accompanying patent claims.
Thus, a builder according to the invention contains
a) hydroxycarboxylic acids produced from polysaccharides as byproducts of alkaline pulping b) possibly reaction products/degradation products of low molecular weight, produced from lignin as byproducts of alkaline pulping c) possibly lignosulfonate separated as a byproduct of sulfite pulping.
The builder according to the invention preferably contains a hydroxycarboxylic acid fraction separated from so-called black liquor, a byproduct of alkaline pulping, a fraction which partly contains or to which there has been added Kraft lignin having a low molecular weight, i.e. approxi¬ mately 1000 g/mol, or to which there has been added ligno- sulf onate .
This advantageous builder in the form of a mixture posses¬ ses the ability to form complexes with polyvalent metal ions, such as calcium, magnesium, iron and manganese, and an ability to disperse small particles in an alkaline aqueous solution.
Component a, even alone, possesses these properties, but using a component mixture which in addition to component a contains also component b and/or component c, these proper¬ ties can be enhanced more than presupposed by the sum of the properties of the components of the mixture, i.e. a synergistic effect is achieved.
The hydroxycarboxylic acids, separated from the black liquor of alkaline pulping, used in the builder according to the invention, resemble in structure the products men¬ tioned above which have been suggested for use as substi¬ tutes for conventional builders, i.e. lactic acid, gluconic acid, glucoheptonate and citric acid.
Approximately 20-100 % of the dry matter content of the builder according to the invention consists of the above- mentioned component a or of a component mixture a and b and/or c, and the balance, approximately 0-80 %, is made up of a conventional builder or conventional builders, such as STPP, TKPP, NTA, and/or EDTA.
The components used in accordance with the invention, sepa¬ rated from the byproducts of pulping, are products of bio- mass dissolution and are therefore not detrimental to the environment. In their trial use as builders it has surpris¬ ingly been observed that their level of performance is almost the same as that of polyphosphates. Products according to the invention are produced in large quantities as byproducts of pulping, and they can be sepa¬ rated from black liquor in an advantageous manner. Such separation operations are known per se and have been de¬ scribed in the literature.
The invention is described below in greater detail with the aid of embodiment examples and comparison experiments.
Textile detergent tests were carried out in a standard laboratory washing machine of the type Terg-O-Tometer by using as the test textile an artificially pigment-soiled cotton (Wasc ereiforschung, Kiefeld, German Federal Repub¬ lic). The washing was carried out at a temperature of 60 °C by using a water having a hardness of 5 degrees dH, and the washing time was 15 minutes. The tenside used in all the tests was 0.5 g BEROL 173/liter (BEROL 173 is a fatty al¬ cohol ethoxylate) , and the builders were mixtures according to Tables 1 and 2. The pH of the washing solution was 10.8 in all the tests. The pH was adjusted by adding sodium hydroxide.
The result of the washing was registered by means of a Zeiss Elrepho reflectometer by using a Xenon lamp as the source of light and a FL-46 filter for the elimination of the effects of optical bleaching agents.
The result is indicated in per cent as a relative removal of black pigment from the textile piece.
Example 1
In test series 1, half of the conventional STPP builder of a washing liquid was replaced by a builder mixture accord¬ ing to the present invention, by using different mixing proportions of the hydroxy acid fraction and lignosulfate, and the washing results were compared with a builder batch based on only STPP and to a reference test in which only one-half of the normal STPP dose was used. In addition, a test was carried out in which one-half of the STPP was replaced by a sodium gluconate builder known per se. The results are shown in Table 1.
Table 1 .
Builder dose Builder mixture Washing result g/i % black pigment removed
0.6 STPP 77.3
0.3 STPP 0.3 Hydroxy acid 71.1 0 Lignosulfonate
0.3 STPP
0.225 Hydroxy acid 76.3
0.075 Lignosulfonate
0.3 STPP
0.15 Hydroxy acid 75.1
0.15 Lignosulfonate
0.3 STPP
0.075 Hydroxy acid 74.2
0.225 Lignosulfonate
0.3 STPP 54.5
0.3 STPP 0.3 Na gluconate 66.2* The results show that the builder according to the inven¬ tion yields a result which is almost as good as that yielded by conventional STPP and considerably better than that yielded by sodium gluconate, a substituting substance kriown per se.
Example 2.
In test series 2, the entire builder dose of the washing liquid was replaced with a builder mixture according to the invention, and the washing result was compared with that obtained with a washing liquid based on a conventional STPP builder and a Na gluconate builder. The test arrangements were otherwise the same as in test series 1. The results are shown in Table 2.
Table 2.
Builder dose Builder mixture Washing result g/i % black pigment removed
0.6 STPP 75.8
0.45 Hydroxy acid 0.15 Lignosulfonate 67.9
0.3 Hydroxy acid 0.3 Lignosulfonate 70.3
0.6 Na gluconate 41.0 The results show that even if the entire builder dose is replaced with a builder mixture according to the invention, a satisfactory washing result is achieved, whereas Na glu¬ conate, a substituting substance known per se, yields a significantly inferior result.
