The enzymes used can be adsorbed onto carrier substances in a known manner, embedded in coating substances and / or granulated with the aid of carrier substances in order to make them easier to handle and to protect them against premature inactivation.
- Such enzymes are preferably in amounts of not more than 2% by weight, in particular from 0.4% by weight to 1.2% by weight, in detergents or cleaning agents prepared using surfactant mixtures according to the invention, in each case based on the total mean.
- the detergents and cleaning agents produced using the surfactant mixtures according to the invention are stable in storage, free-flowing and stable in color. Another advantage is that when the surfactant mixtures according to the invention are used, largely inert filler salts, in particular alkali metal sulfate, can be dispensed with. Examples
- Alkyl sulfate, the sodium silicate and the alkyl glycoside, the zeolite in the form of an approximately 50% by weight aqueous slurry, the alkyl glycoside as an approximately 50% by weight aqueous solution and the sodium silicate in the form of an approximately 35% by weight water glass solution was set, an aqueous slurry containing 44 wt .-% water was generated from the raw materials listed in Table 1.
- This slurry which had viscosities of 4500 mPa.s to 6400 mPa.s at 60 ° C to 80 ° C, was heated to temperatures of approximately 60 ° C to 80 ° C and
- the free-flowing powder Ml characterized in Table 1 by its composition was obtained with an average grain size of around 0.5 mm, which was free of particles over 1.8 mm in diameter, had dust contents of 0.15% by weight and a bulk density of Had 540 grams per liter.
- the detergent W1 was prepared by simply mixing the amount of the powder according to the invention specified in the table below with conventional detergent ingredients. In washing tests under application conditions (drum washing machine Miele W 716, 3.5 kg of normally soiled laundry, water hardness 16 ° d, dosage 98 g detergent), this showed an average of all soiling at 30 ° C as well as at 60 ° C and 90 ° C a washing power which at least reached the level of a commercial heavy-duty detergent tested for comparison purposes with a fatty alkyl polyethoxylate / alkylbenzenesulfonate surfactant component.
- the agent according to the invention performed significantly better, especially in the case of cosmetic soiling.
