The invention "relates to / improved detergents and their manufacture .. In particular, the invention relates to detergents comprising a non-phosphate detergent existing structural component, which constitutes a considerable proportion of a certain group of Contains polymer as an essential component.

In summary, the cleaning agent according to the invention consists of about 1 to about 50 parts by weight of a surface-active cleaning agent and from VlO (0.1) to about ten (10) parts by weight, per part by weight of the surface-active cleaning agent, of a high phosphate builder.

a linear, aliphatic structure with side chains that give the polymers complexing properties. At least about IQfi (on an average number basis) of the side chains consist of N-carboxymethyl-. or F-carboxymethylamide side chains. As a precaution, the N-carboxymethyl and / or Üf-carboxymethylamide side chains are H ^ F-dicarboxymethyl and !!, N-dicarboxymethylamide groups.

Sodium tripolyphosphate is usually considered cheaper Builder to support the cleaning effect and for inactivating the hardness of water in cleaning compounds and means used.

The phosphate introduced into sewage in this way acts as a metabolite for algae etc. in the receiving waters and promotes their eutrophication. It has now been found that the replacement of sodium polyphosphate with marriage-forming polymers of the type described in U.S. Patents 3,331,773 and 3,285,886, which have both sparing properties for hardness control and threshold effectiveness, so that only small amounts are required results in an improved product. The hardness is still regulated, but no phosphate is introduced into the wastewater. Expensive wastewater treatments to "prevent" the entry of phosphate into rivers and lakes are therefore not necessary. * The chelating polymers also have the advantage that they are biodegradable.

Actually, surface-active cleaning agents are used can be used in the Invention dinners

be used. Typical groups are the alkali metal soaps, änioniscnes, synthetic detergents, non-ionic, synthetic cleaning agents, ampho-

tere »synthetic detergents and ampholytic, synthetic detergents. All of these surface-active cleaning agents are known to those skilled in the art known. For brevity, reference is made to the TTSA patent 3,324,038, in particular on column 2 “line 40 to column 5, line 7. This patent specification is thus used to explain the present invention.

As already said, they are also considered to be an essential component the water-soluble, organic, polymeric structure used in the cleaning agents according to the invention of fe known per se to the person skilled in the art. Countless examples of suitable ones polymeric builders for the purposes of the invention are disclosed in U.S. Patents 3,285 and 3,331,773. Reference is therefore also made here to the content of this patent specification. Among the polymers mentioned in these patents, poly- - (NjN-dicarb-oxymethylacrylamide) with a molecular weight from about 200,000 to about 2,000,000, and in particular from about 380,000 to about 1,300,000, preferably. Another example of suitable polymer builders, is poly (N, N-dicarboxymethylvinylamine) and its what soluble salts, e.g. ... the disodium salt,

According to the invention, the N-carboxymethyl and / or N-oxymethylamide groups in the polymer builder at least about 10, and preferably about 50 to 100 .- (e.g. 95; ^ Pxo.cent .. {au-i £ number basis) of the reactive side chains in the chelating agent used

Make up polymers.

The polymer builder can be about 10 Ms 100, and preferably about 10 to about 50 (e.g. 30) by weight make up the total weight of the constituents of the builder. As noted, other building salts may be used not be of the phosphate type. Otherwise the choice is unlimited and can build up compounds, e.g. alkali carbonates (e.g. sodium carbonate, sodium or potassium bicarbonate etc.), alkali borates, alkali silicates (e.g. sodium metasilicates) or organic alkaline ones separating builder salts, e.g. those mentioned in U.S. Patent 3,324,038 column 5, lines 40-65, include.

As noted, the weight ratio of surfactant is Detergent to non-phosphate between about 0.1 and about 500. Preferably this ratio is about 2.0 to about 50 volts

Optionally, the cleaning agent according to the invention even less important ingredients, including dirt-suspending agents (e.g. carboxymethyl cellulose), optical gloss agents, dyes, corrosion inhibitors, diluents (e.g. sodium sulfate, sodium chloride, etc.) and the like. Be added.

The cleaning agents according to the invention can be produced and stored or in the form of dry powders or granular mixtures, in tablet form or in the form similar agglomerates or in aqueous up to 90 or % By weight, based on the total weight of the solution, water or a water-based solvent (e.g. alcohol)

(a) Production of poly (N, N-dicarboxymethy! vinylamine)

Polyacrylamide is modified by A.M. Schiller and T.iJ.Suen under the title "Ionic Derivates of Polyacrylamid", Industrial and Engineering Chemistry, Volume 48, page 2132 (December 1956). To 280 ecm of a 5 solution of a polyacrylamide with a molecular weight of about 1,000,000 were added 6.4 g of a 50% sodium hydroxide solution. These Mixture was chilled in a refrigerator. A separate container containing 35 ecm of a sodium hypochlorite solution with 8.1 $ available chlorine contained »was also included in the Refrigerator chilled. Compartment of cooling each solution at about 4.5 ° C they were mixed well with thorough stirring. The temperature of the reaction mixture rose in the process to 15.6 ° C., during which time a considerable evolution of an odorless gas was observed. The reaction mixture was then left in stand continuously stirring overnight. The conversion to Polyvinylamine was valued at $ 50. The reaction product was by adding 10 g of sodium cyanide and while stirring until completely dissolved, heating ■ to 50 ° C and subsequent addition of 22 ecm one 36% formaldehyde solution through a dropping funnel
