Definitions
- the present invention relates to silicate-containing detergent compositions containing a high bulk density, very good solubility and very good primary and secondary washing power, in particular have a high fat washability. Specifically affects
- Detergent compositions are known from European patent EP-B-0 698 658 (Procter & Gamble), which have an improved fat and oil wash-out capacity. These compositions contain 1 to 90% by weight of an anionic alkylbenzenesulfonate-free surfactant system comprising at least 30% by weight of an alkoxylated alkyl sulfate with an average degree of alkoxylation of 0.1 to 10, with defined weight ratios of mono-, di-, tri- and higher alkylated Fatty alcohol sulfates are present.
- EP-B-0 698 659 (Procter & Gamble) extends this surfactant system to be used to the use of less than 40% by weight alkylbenzenesulfonate (ABS).
- ABS-containing detergent composition also has an improved wash-out capacity for oil and grease stains.
- silicates to nonionic surfactants are known, for example, from WO96 / 20269 (Henkel). Neither these nor other documents which deal with the exposure of silicates to nonionic surfactants impose restrictions on the particle size distribution or the bulk density of the silicate used.
- silicate builder components are preferred which have at least 40% of the particles sizes between 0.4 and 0.8 mm.
- the process according to the invention can be carried out in both high-intensity and slow-running mixers.
- high-speed mixers are the Lödige® CB 30 recycler, the Schugi® granulator, the Eirich® mixer type R or the Drais® K-TTP 80

- the delay in dissolution compared to conventional amorphous sodium silicates can be caused in various ways, for example by surface treatment, compounding, compacting / compaction or by overdrying (for example water content of the silicate below 18% by weight).
- the term “amorphous” is also understood to mean “X-ray amorphous”.
- silicates in X-ray diffraction experiments do not provide sharp X-ray reflections, as are typical for crystalline substances, but at most one or more maxima of the scattered X-rays, which have a width of several degree units of the diffraction angle.
- it can very well lead to particularly good builder properties if the silicate particles provide washed-out or even sharp diffraction maxima in electron diffraction experiments. This is to be interpreted as meaning that the products have microcrystalline areas of size 10 to a few hundred nm, values up to max. 50 nm and in particular up to max. 20 nm are preferred.
- Such so-called X-ray amorphous silicates which also have a delay in dissolution compared to conventional water glasses, are described, for example, in German patent application DE-A-44 00 024 .

- the sulfuric acid monoesters of the straight-chain or branched C 7-21 alcohols ethoxylated with 1 to 6 mol of ethylene oxide such as 2-methyl-branched C 9-11 alcohols with an average of 3.5 mol of ethylene oxide (EO) or C 12-18 - Fatty alcohols with 1 to 4 EO are suitable. Because of their high foaming behavior, they are used in cleaning agents only in relatively small amounts, for example in amounts of 1 to 5% by weight.
- Suitable anionic surfactants are also the salts of alkylsulfosuccinic acid, which are also referred to as sulfosuccinates or as sulfosuccinic acid esters and which are monoesters and / or diesters of sulfosuccinic acid with alcohols, preferably fatty alcohols and especially ethoxylated fatty alcohols.
- alcohols preferably fatty alcohols and especially ethoxylated fatty alcohols.
- Preferred sulfosuccinates contain C 8-18 fatty alcohol residues or mixtures thereof.
- Particularly preferred sulfosuccinates contain a fatty alcohol residue which is derived from ethoxylated fatty alcohols, which in themselves are nonionic surfactants (description see below).
- alk (en) ylsuccinic acid with preferably 8 to 18 carbon atoms in the alk (en) yl chain or salts thereof.
- Soaps are particularly suitable as further anionic surfactants.
- Saturated fatty acid soaps are suitable, such as the salts of lauric acid, myristic acid, palmitic acid, stearic acid, hydrogenated erucic acid and behenic acid, and in particular soap mixtures derived from natural fatty acids, for example coconut, palm kernel or tallow fatty acids.
- those soap mixtures are preferred which are composed of 50 to 100% by weight of saturated C 12-24 fatty acid soaps and 0 to 50% by weight of oleic acid soap.
- the anionic surfactants including the soaps can be in the form of their sodium, potassium or Ammonium salts and as soluble salts of organic bases, such as mono-, di- or Triethanolamine.
- the anionic surfactants are preferably in the form of their Sodium or potassium salts, especially in the form of the sodium salts.
- the agents can also contain components that make oil and fat washable made of textiles. This effect is particularly evident if a textile is soiled, which has previously been repeatedly with an inventive Detergent containing this oil and fat-dissolving component is washed has been.
- the preferred oil- and fat-dissolving components include, for example, nonionic Cellulose ethers such as methyl cellulose and methyl hydroxypropyl cellulose with one Proportion of 15 to 30% by weight of methoxyl groups and of hydroxypropoxyl groups from 1 to 15% by weight, based in each case on the nonionic cellulose ether, as well as the polymers of phthalic acid and / or of the known from the prior art Terephthalic acid or its derivatives, in particular polymers of ethylene terephthalates and / or polyethylene glycol terephthalates or anionically and / or nonionically modified Derivatives of these. Of these, the sulfonated ones are particularly preferred Derivatives of phthalic acid and terephthalic acid polymers.
- a finely divided silicate carrier composed of 5% by weight of sodium carbonate, 76% by weight of water glass and 19% by weight of water was produced by spray drying. The particle size distribution was ⁇ 2.0 mm with 86% of the particles between 0.8 and 0. 4 mm was brought. This carrier was loaded with nonionic surfactant and had a bulk density of 824 g / l. The remaining surfactants, builders and additives were added to a Lödige mixer and the silicate charged with nonionic surfactant was added while the mixer was running.
- the agent E1 according to the invention was obtained with a bulk density of 760 g / l and the composition [% by weight]: Soap 0.76 C 13 alkylbenzenesulfonate Na 7.49 C 8 -C 18 fatty alcohol sulfate 11.48 Water glass 11.29 sodium 1.01 Zeolite A 19.09 C 13-15 oxo alcohol 3 to 7 EO 2.39 C 12 -C 18 fatty alcohol 7 EO 1.04 Sokalan CP5® 3.58 Tylose 0.24 opt.
- Sokalan CP5 ® is an acrylic acid-maleic acid copolymer from BASF Repelotex ® is a terephthalic acid-ethylene glycol-polyethylene glycol ester from Rhône-Poulenc.
- the application test was carried out under practical conditions in one Household washing machine (Miele W 717). For this, the machine was cleaned with 3 kg Filling laundry and 0.5 kg test fabric soiled with natural grease (cotton / linen) loaded. Washing conditions: tap water of 16 ° dH (equivalent to 160 mg CaO / l), amount of detergent used per detergent: 76 g, washing temperature 60 ° C, Washing time 60 min, liquor ratio (kg of laundry to liter of washing water in Main wash cycle) 1 to 5.7, rinse three times with tap water, spin off and Dry.
- Coffee W 717 Household washing machine
- the agent E1 produced by the method according to the invention was tested against two commercially available universal detergents V1 and V2, the test fabrics being examined after drying in accordance with DIN 6174 (colorimetric determination of color differences in body colors) using a Minolta CR 300 (3-point measurement).
- the results of the color distance measurements are summarized in Table 1: Color distance values medium E1 V1 V2 dE (w) (initial value - wash value) 43.3 31.2 30.7
