Description

The invention relates to granulated washing and cleaning agents which contain a certain mixture of anionic surface-active agents Substances, certain amounts of certain organic and / or inorganic salts and moisture contain. Such agents are formulated so that they have a high foaming power and effective detergency, as well as product stability. You let yourself under Establish the use of devices that are customary for detergents.

For years, commercial, synthetic detergents and cleaning agents contained substantial amounts of inorganic Phosphate salts used as builders. Such Phosphatτ Builders are used to make mineral ions, which normally

409820/1091

contained in household tap water, complex to bind, to prevent such ions from the cleaning behavior the synthetic surfactants in such agents interfere. Phosphate builders are also responsible for the physical stability of granulated detergent products.

However, recent studies have shown that the phosphate builders can pose ecological problems because they serve as nutrients that promote algae growth and thereby biological aging (eutrophication) accelerate from natural waters. As a result of these possible harmful effects in constant use deir phosphate frameworks * in substantial quantities, endeavored one is looking to find ways of reducing the need for phosphate salts in commercial detergents and cleaning agents can be reduced or eliminated.

A method, the absence of mineral complex * - forming phosphate builder salts in detergent and cleaning agent formulations To compensate, consisted in synthesizing agents that made the systems more surface-active Contained substances that were particularly insensitive to the mineral hardness of washing solutions. Such systems Surface-active substances contained, for example, relatively mineral-insensitive anionic surface-active substances Substances or mixtures thereof (cf. US-PSS 2,086,215; 2,0? M51; 3,223,645; 3,322,876; 3,332,880; 3,513,099 and 3,658,727 and BE-PS 650,323 and German patent application

A mineral-insensitive product that is particularly preferred due to the commercial availability of its components anionic surface-active substance mixture contains a combination of the usual, relatively strong foaming, relatively mineral-sensitive alkylbenzenesulfonates and usual

Attempts, low-phosphate or phosphate-free granulated alkylbenzenesulfonate / alkylether sulfate detergents and cleaning agents (and the resulting economic advantages of granulated products) by conventional spray drying processes however, it was not entirely successful. The addition of an alkyl ether sulfate as a surfactant -Fabric to spray dried * or puffed / alkyl benzene sulfonate granules containing surfactants posed problems with regard to foam behavior,

Processability and granulate stability.

While the addition of alkyl ether sulfate as a surface-active substance to such granules, the system of surface-active Makes substances less sensitive to water hardness (i.e. Ca and Mg ions) and therefore more suitable for detergent and cleaning agent formulations that do not contain any Have builders or only a few builders this addition tends to act as a sales advantage for heavy duty detergents generally desired high foaming power of the alkylbenzenesulfonates to reduce. Also causes the Incorporation of alkyl ether sulfates into spray-dried detergent granules. Difficulties in processing such granules. Finally, the incorporation of the alkyl ether sulfates into blown detergent granules (connected with the omission or reduction of hygroscopic phosphate salts) generally the granulated end products more sensitive to caking and throws pourability and shelf life problems.

Storage stability test

The storage stability of the agents according to the invention was determined with the aid of a storage stability test. The granulated compositions to be tested were packaged in two-layer and multilayer cardboard boxes waxed on the outside, which had various types of closures, and stored for different times in chambers with constant temperature and humidity. These chambers were generally maintained under conditions varying between ambient temperature and humidity and the rather severe temperature / humidity conditions of 26.7 ° C and 80 % relative humidity. At certain time intervals, the agents to be tested were removed from the temperature / humidity constant environment and tested in order to determine the caking and pourability properties after this storage.
