Description

Foaming detergents It has been found that foaming detergents and detergents Cleaning agents can thereby improve in unexpected and surprising ways, Soaps containing water-soluble salts of polysaccharide etheric acids are used provides.

The water-soluble salts of the polysaccharide ether acids are the alkali salts, such as the sodium and potassium salts, as well as the salts of nitrogen compounds, such as the ammonium salts, and the salts of organic nitrogen bases into consideration. As polysaccharide etheric acids can use both the polysaccharide: ether carboxylic acids and the polysaccharide ether sulfonic acids and the sulfuric acid esters of oxyalkylated polysaccharides can be used. As an addition, you can z. B. the water-soluble salts of cellulose alkyl ether carboxylic acids 'and Cellulo @ searalkylether carboxylic acids, such as cellulose glycolic acids, cellulose lactic acids, the etherification product of cellulose with the sodium salt of ß-chloroethoxyacetic acid, Cellulosebenzyläthercarbonsäuren, Celluloseoxybenzyläthercarb, onsäuren, their homologues and use analogs and substitution products and the like.

The cellulose ether acids or their salts can easily be converted of halocarboxylic acids or halosulfonic acids, e.g. B. chloroacetic acid, chloropropionic acid, Chlorobutyric acid, chloromethylbenzoic acid; Chloromethylsalicylic acid, chloromethyl cres -otinic acid, ß-bromoethane-a-sulfonic acid, y-chloro-ß-oxy-propane-a-sulfonic acid, benzyl chloride-p-sulfome: acid, Chloroacetic acid [methyl - @ (ß-sulfons, Äureäthyl) -amid] and: ß- [K-sulfoethoxy] -äthyl-. chloride and the like m. with cellulose, regenerated cellulose or degraded cellulose, preferably in the presence of alkaline substances.

Instead of the above-mentioned Cellüloserderi: ate can also the analogous starch ether acids are used.

The foaming detergents can also contain conventional detergent additives contain. So you can have a further content of alkali carbonates, water glass, Alkali metasilicates, alkali borates, also bleaching agents, especially per compounds, such as peroxides and persalts. The addition of salts is particularly advantageous those phosphoric acids which are lower in water than orthophosphoric acid, d. H. of alkali pyrophosphates, alkali metaphosphates and alkali polyphosphates; but has The addition of alkali orthophosphates, such as disodium phosphate and trisodium phosphate, also stands out, proven.

The addition of the water-soluble salts of polysaccharide ether acids to soaps surprisingly has a very beneficial effect in several ways. So the washing and cleaning power of the soaps is largely increased, so that a considerable saving is possible. Likewise, the foaming property becomes favorable influenced; one generally obtains one when using the new additives particularly resistant foam. While one with the previous use of the detergent is often dependent on using largely softened water this is not the case with the detergents improved according to the present invention necessary. The fabrics washed with the new detergents stand out in particular due to increased durability and a soft grip, since the al storage of through the hardness components of the water largely caused precipitation on the fabrics is avoided by the new additives.

The new foaming detergents can be prepared by mixing the ingredients in mixing devices such as agitators, ball mills. Furthermore can the mixing of the dry or water-containing components is carried out by atomization. The finished mixtures can be placed on the market; the ingredients can can also only be mixed at the place of use. You can do them individually or at the same time Dissolve in the treatment fluids or the solutions of the components mix together.

It is already known to soaps both starch and sugar and cellulose ethers to add. These additions show. but not the effect of the water-soluble salts of polysaccharide etheric acids, which consists in that a reprecipitation the dirt particles on the laundry that are detached by the silk are prevented. _- Beisp1.e1 4o parts by weight of soap, 2o parts by weight of soda and 5 parts by weight of .des Sodium salt of cellulose glycolic acid are mixed well with one another. Of this Detergents are used, numerous solutions for washing white laundry. the Washed fabrics do not yellow and are characterized by a soft handle. the end.
