- the invention relates to a granular washing and cleaning agent which contains anionic surfactants which are obtained entirely or at least to a large extent from renewable raw materials.
- oleochemical surfactant compounds which are obtained from renewable vegetable and / or animal raw materials and which have a high ecological compatibility, is of great and rapidly increasing importance.
- oleochemical surfactant compounds with high environmental compatibility are the known fatty alcohol sulfates, which in particular by sulfating fatty alcohols of vegetable and / or animal origin with predominantly 10 to 20 carbon atoms in the fatty alcohol molecule and subsequent neutralization to form water-soluble salts the corresponding alkali salts, and the known ⁇ -sulfofatty acid alkyl esters (ester sulfonates), which are obtained by o-sulfonation of the methyl esters of fatty acids of plant and / or animal origin with predominantly 10 to 20 C atoms in the fatty acid molecule and subsequent neutralization to form water-soluble mono Salts, in particular the corresponding alkali salts, and their disalts obtainable by hydrolysis.
- oleochemical surfactant compounds are sulfonated fatty acid glycerol esters, for example sulfonated unsaturated fatty acid glycerol esters as described in international patent application WO 91/6532, or sulfonation products of saturated fatty acid glycerol esters as described in international patent application WO 91/9009.
- the anionic surfactant that is still economically most important today belongs to the surfactant class of alkylbenzenesulfonates.
- a disadvantage of these alkylbenzenesulfonates is that they are obtained from petrochemical raw materials.

A particularly preferred dye is Tinolu® (R) (commercial product from Ciba-Geigy).
- the granular detergents and cleaning agents according to the invention can have a bulk density between about 300 and 1100 g / 1.
- Granules are preferred which have a bulk density between 600 and 1100 g / l.
- the granular detergents and cleaning agents can be produced by any of the known processes.
- the granules can be produced by spray drying an aqueous slurry and, if appropriate, then adding temperature-sensitive components.
- the granular washing and cleaning agents can be produced by one of the known granulating or extruding processes.
- the granules are produced by an extrusion process which is described in international patent application WO 91/2047.
- the granular detergents and cleaning agents are prepared by using the sulfated fatty acid glycerol esters in the form of a spray-dried or granulated compound as an additive component to other granular constituents of detergents and cleaning agents.
- the sulfur trioxide was expelled from a corresponding amount of 65% by weight oleum by heating, diluted to a concentration of 2% by volume with nitrogen and blown in at the side of the reactor head.
- the crude sulfonation product was subjected to a post-reaction at 80 ° C. for 30 minutes.
- the acidic sulfonation product was then continuously neutralized to pH 6.5 to 7.5 using aqueous 25% strength by weight sodium hydroxide solution.
- Table 1 Average composition of the fatty acid glycerol esters used after curing, in% by weight
- HK hardened coconut oil
- HPK hardened palm kernel oil
- Washing program colored washing program (without prewash) at 30 ° C, 40 ° C or
- the stains were:
- compositions of the basic agents W1 and W2 were (data in% by weight):
- the agents consisted of spray-dried granules, which were sprayed with ethoxylated Ci2-C] .8 fatty alcohol and to which the temperature-sensitive components were subsequently mixed.
- the bulk density was 650 g / 1 or 670 g / 1.
- Wl / 3 mixture of sulfated HK and tallow fatty alcohol sulfate in a weight ratio of 1: 1
- Wl / 4 mixture of sulfated HPK and tallow fatty alcohol sulfate in a weight ratio of 1: 1
- Example 1 Testing Wl, dosage 80 g
- Example 2 Testing of Wl, dosage 120 g. The tests were repeated as in Example 1.
