Based on the weight of the washing and Detergent compositions comprising the invention Containing soil release oligoester, the proportion of enzymes is at least 0.001% by weight, preferably between about 0.001% by weight to about 5% by weight, in particular from about 0.001% by weight to about 1% by weight, especially from about 0.01% to about 1% by weight.
- Example 3 was repeated, Mg stearate being used as the additive instead of Ca stearate.
- the free-flowing granules obtained had a bulk density of 519 g / l and the following particle size distribution: 0.1-0.6 mm 26% 0.6 - 1.0 mm 64%% 1.0 - 2.0 mm 10%
- Alkanesulfonate as in Example 1 was premixed with 50 g of hydrophobic silica (Sipernat D 17) and ground on a laboratory screen grinder with a hole size of 6 mm and a product throughput of 60 kg / h.
- the granules obtained had the following grain size distribution: 0.1-1.0 mm 81% 1.0 - 2.0 mm 19%
- Example 2 5000 g sec. Alkanesulfonate as in Example 1 were treated with 100 g of hydrophilic silica (Sipernat® 22 S) and ground as described in Example 3. The bulk density of the free-flowing granules was 532 g / l. A sieve analysis showed the following grain size distribution: 0.1-1.0 mm 88% 1.0 - 2.0 mm 12%

Description
Eine andere Möglichkeit besteht darin, das erfindungsgemäße pulver- oder granulatförmige SAS zu festen Extrudaten wie zum Beispiel Waschstücke, bar soaps oder Toilettensteine, zu Preßlingen, z.B. Tabletten, oder Kompaktaten (Walzen) zu verarbeiten.
Alkylestersulfonate, Alkylsulfate, Alkylethersulfate, Alkylbenzolsulfonate, Olefinsulfonate und Seifen, wie im folgenden beschrieben.
worin R einen unsubstituierten C10-C24-Alkyl- oder Hydroxyalkylrest, bevorzugt einen C12-C20 Alkyl- oder Hydroxyalkylrest, besonders bevorzugt C12-C18-Alkyloder Hydroxyalkylrest darstellt. A ist eine Ethoxy- oder Propoxyeinheit, m ist eine Zahl größer als 0, vorzugsweise zwischen ca. 0,5 und ca. 6, besonders bevorzugt zwischen ca. 0,5 und ca. 3 und M ist ein Wasserstoffatom oder ein Kation wie z. B. Natrium, Kalium, Lithium, Calcium, Magnesium, Ammonium oder ein substituiertes Ammoniumkation. Spezifische Beispiele von substituierten Ammoniumkationen sind Methyl-, Dimethyl-, Trimethylammonium- und quartemäre Ammoniumkationen wie Tetramethylammonium und Dimethylpiperidiniumkationen sowie solche, die von Alkylaminen, wie Ethylamin, Diethylamin, Triethylamin oder Mischungen davon abgeleitet sind. Als Beispiele seien C12- bis C18-Fettalkoholethersulfate genannt wobei der Gehalt an EO 1, 2, 2.5, 3 oder 4 mol pro mol des Fettalkoholethersulfats beträgt, und in denen M Natrium oder Kalium ist.
