"Laundry detergent"

The invention relates to a laundry detergent with reduced Phosphate content and a substantial content of nonionic surfactants.

The effect of modern laundry detergents was due in large part to their high sodium triphosphate content traced back. One of the advantageous properties of sodium triphosphate is its ability to bind complexes Calcium, magnesium, iron and other heavy metal ions, the synergistic influence on the surface activity of soaps and synthetic surfactants, the dirt-carrying capacity and the detachment and peptising capacity against dirt particles as well as the neutralization of acidic dirt. The high sodium triphosphate content of the However, detergent is known to be criticized by the public in connection with questions of environmental protection because it contributed greatly to the eutrophication of surface waters. Numerous phosphate substitutes are therefore already available determined or tried to reduce the phosphate content by changing the surfactant composition balance.

The object of the invention was therefore to develop detergents which have a lower triphosphate content than that have known agents, but are not inferior to these in their washing and cleaning power.

It is known that ethoxylated nonylphenols are used as detergent ingredients have a very good effectiveness, especially when it comes to washing out fatty soiling goes. There are agents on the market that contain mixtures, e.g. of nonylphenol + 9 EO and nonylphenol + 6 EO (x EO = χ mol of ethylene oxide per mol of nonylphenol).

A disadvantage of the nonylphenol ethoxylates in detergents is their tendency to cause disruptive foam development Rinsing, especially in the presence of the anionic surfactants essential for detergents such as the alkylbenzenesulfonates, what both the amount of this nonionic

15 surfactants as well as the anionic surfactants.

It has now been shown that by using certain three-way combinations of alkyl, in particular of nonyl ' phenol ethoxylates, on the one hand, make detergents with a lower phosphate content more readily washable and on the other hand the foam safety of the combination of alkylphenol ethoxylates / alkylbenzenesulfonates can be vastly improved.

The detergents according to the invention can be used as heavy-duty, pre-wash and heavy-duty detergents. Preparations that are to be used as pre-wash detergents - like heavy-duty or high-temperature detergents - have a pH value between 9> 5 and 11.5 in an aqueous solution, which is achieved by adding washing alkalis. Preparations suitable as cleansing agents are less alkaline; in 1% aqueous solution they have a pH value between about 8.5 and 9.5. The cooking or heavy-duty detergents also differ from the other preparations by the content of a bleaching component, which consists of an inorganic or organic peroxy compound as an active oxygen carrier, in particular natrl perborate or magnesium monoperphthalate, stabilizers and optionally activators for the peroxy compound, and which are 1 to 30, preferably 2 to can represent% of the total detergent - 25 wt..

This includes the polyethylene glycol derivatives of the above definition, in any case the active oxygen carriers, enzymes, antimicrobials, foam inhibitors, dyes and fragrances. With the subsequent admixture it is advantageous, especially for the gentle incorporation of smaller amounts of active ingredients, into these by mixing with a solid carrier substance, for example by spraying on sodium sulfate, initially to be converted into a dry powdery intermediate product, so that it adheres to the powder, agglomerate or granulate particles adhere as small discrete particles.

The composition of the detergents is shown in the table below. A and B are analytically determined market products. Examples 1 and I to III correspond in their composition to the teaching of the present invention, while Examples a to e also served for comparison purposes.

The assessment of the washing results showed by visual inspection and measurement in the ELREPHO device that the Formulations 1 and II to IV are clearly superior to formulations A and B when it comes to removing mascara and make-up was. The lipstick stain disappeared Completely. The foaming behavior was best with recipe II.

If you worked with formulas A and B, i.e. without low ethoxylated nonylphenol, the foam behavior is not acceptable despite higher soap content. Foam dampening can be achieved by adding E.g. propoxylated EO adducts with secondary, aliphatic alcohols are achieved, but this does not result in any simultaneous increase in Pett washability achieved.
