- the cellulose used here can be obtained from bacteria or fungi and should have an optimal pH range between 5 and 9.5 exhibit. Suitable celluloses are disclosed in US 4,435,307. It is cellulose which is produced by a strain of Humicola insolens, in particular the strain Humicola DSM 1800 or another cellulose-212-producing fungus which belongs to the genus Aeromonas, and cellulose which extracts from the hepatopancreas of certain marine mollusks has been. Suitable celluloses are also disclosed in GB-A-2,075,028, GB-A-2,085,275 and DE-OS-2,247,832.
- the detergent compositions according to the invention contain enzymes in amounts of up to about 50 mg, preferably from about 0.01 mg to about 10 mg, per gram of the detergent composition. Based on the weight of the detergent and cleaning agent compositions which contain the soil release oligoesters according to the invention, the proportion of the enzymes is at least 0.001% by weight, preferably between about 0.001% by weight and about 5% by weight, in particular about 0.001% by weight. % to about 1% by weight, especially from about 0.01% to about 1% by weight.
- Alkanesulfonate as in Example 1 was mixed intensively with 10 g of calcium stearate and then ground on a laboratory screen basket mill (universal mill with cross beater) with a product throughput of 70 kg / h.
- the laboratory screen basket mill universal mill with cross beater
- Hole diameter of the strainer was 6 mm.
- 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:
- Magnesium oxide and magnesium silicate 1: 1 mixed.
- the pellets treated in this way were placed on a laboratory sieve basket mill with a hole size of 8 mm and a
- Treated silica (Sipernat® 22 S) and grind as described in Example 3.
- the bulk density of the free-flowing granules was 532 g / l.
- the sieve basket consists of a perforated plate with a 6 mm
