Definitions

  • the present invention relates to enclosed bleach activators of the quaternized aminoalkylnitrile type.
  • washing auxiliaries include diverse groups of active substances, such as foam regulators, antiredeposition agents, bleaches and color transfer inhibitors.
  • active substances such as foam regulators, antiredeposition agents, bleaches and color transfer inhibitors.
  • Auxiliaries of this type also include substances which aid the surfactant performance as a result of oxidative degradation of soilings located on the textile or those in the liquor. Analogous statements also apply to cleaners for hard surfaces.
  • inorganic peroxygen compounds in particular hydrogen peroxide, and solid peroxygen compounds which dissolve in water to liberate hydrogen peroxide, such as sodium perborate and sodium carbonate perhydrate, have been used for a long time as oxidizing agents for disinfection and bleaching purposes.
  • the oxidative effect of these substances greatly depends in dilute solutions on the temperature; thus, for example with H 2 O 2 or perborate in alkaline bleaching liquors, a sufficiently rapidly bleaching of soiled textiles only takes place at temperatures above about 60° C.
  • bleach activators for which numerous proposals, primarily from the classes of substance of N- or O-acyl compounds, for example polyacylated alkylenediamines, in particular tetraacetylethylene-diamine, acylated glycolurils, in particular tetraacetylglycoluril, N-acylated hydantoins, hydrazides, triazoles, hydrotriazines, urazoles, diketopiperazines, sulfurylamides and cyanurates, and also carboxylic anhydrides, in particular phthalic anhydride, carboxylic esters, in particular sodium nonanoyloxybenzenesulfonate, sodium isononanoyloxy-benzenesulfonate and acylated sugar derivatives, such as pentaacetylglucose, have become known in the literature.

  • Toluenesulfonate and cumenesulfonate are understood here as meaning the anion of the ortho, meta or paraisomers of methylbenzenesulfonic acid and isopropylbenzenesulfonic acid, respectively, and any desired mixtures thereof. para-isopropylbenzenesulfonic acid is particular preferred.
  • the compound according to general formula I can be used in solid form as it is or formulated in particulate form, i.e. applied to an organic and/or inorganic carrier material, as starting material for the enclosure according to the invention.
  • the compound according to formula (I) can be applied to the carrier material by stirring the carrier material into a solution of the compound according to formula I, as formed during the course of its production, and stripping off the optionally aqueous solvent under reduced pressure, if desired at elevated temperature.
  • Suitable carrier materials are all substances which do not interact in an unreasonably negative manner with the compound according to formula I, for example alkali metal cumenesulfonate, surfactants, organic acids and polymers, alkali metal carbonates, alkali metal sulfates, alkali metal hydrogen sulfates, alkali metal hydrogen carbonates, alkali metal phosphates, alkali metal dihydrogen phosphates, dialkali metal hydrogen phosphates and alkali metal silicates and mixtures thereof.
  • silicatic carrier materials particularly suitable for the purposes of the present invention include, for example, alkali metal silicates, and also silicas, silica gels and clays, and mixtures thereof.
  • the carrier material is preferably free from zeolites.
  • the silicate-containing carrier material optionally comprises further particulate inert constituents which do not unreasonably impair the stability of the compounds according to the formula I.
  • Silicas which have been produced by a thermal process (flame hydrolysis of SiCl 4 ) (so-called pyrogenic silicas) are equally suitable for use as are silicas produced by wet methods.
  • Silica gels are colloidal silicas with an elastic to solid consistency and a substantially loose pore structure, resulting in a high liquid-uptake capacity. They can be produced by the action of mineral acids on waterglass.
  • Clays are naturally occurring crystalline or amorphous silicates of aluminum, iron, magnesium, calcium, potassium and sodium, for example kaolin, talc, pyrophyllite, attapulgite, sepiolite, montmorillonite and bauxite.
  • the use of aluminum silicate as a carrier material or as a component of a carrier material mixture is also possible.
  • the carrier material preferably has particle sizes in the range from 100 ⁇ m to 1.5 ⁇ m.
  • the coating materials should have proven as far as possible to be substantially chemically inert toward the bleach activator, i.e. the degradation rate for the particles containing the bleach activator according to formula (I) to be used according to the invention, which are stored for about 4 months, should be as low as possible.
  • the coating materials must be sufficiently rapidly soluble in water or aqueous solutions so that the granules, as constituents of detergents or cleaners, upon use thereof in corresponding aqueous detergent or cleaner solutions, release the bleach activator at the desired point in time, or over the desired period of time.
  • the use of the correspondingly enclosed particles in textile detergents often results in a greater avoidance of color damage of textiles washed therewith than does the use of the pure substance according to formula (I).
  • Suitable coating materials for the purposes of this invention are, in particular, inorganic salts, such as alkali metal sulfates, alkali metal chlorides, alkali metal silicates, alkali metal phosphates and alkali metal phosphonates, alkaline earth metal sulfates and alkaline earth metal silicates, paraffin waxes, water-soluble saccharide-based polymeric compounds, such as starch or starch derivatives or cellulose derivatives, polymeric alcohols, for example polyvinyl alcohols and polyethylene glycols, homo- and copolymeric polycarboxylates, polyesters of dicarboxylic acids and optionally oligo- or polymeric alcohols, nonionic surfactants, anionic surfactants, hydroxy carboxylic acids, such as glycolic acid and citric acid, and/or fatty acids.
  • inorganic salts such as alkali metal sulfates, alkali metal chlorides, alkali metal silicates, alkali metal phosphates
  • sodium is the preferred alkali metal ion and magnesium is the preferred alkaline earth metal ion.
  • Paraffin wax generally represents a complex substance mixture without a sharp melting point. For characterization, determination is usually made of its melting range by differential thermal analysis (DTA), as described in “The Analyst” 87 (1962), 420, and/or of its solidification point. This is understood as meaning the temperature at which molten material converts from the liquid state to the solid state by slow cooling. Preference is given to using waxes which solidify in the range from 20° C. to 70° C. Here, it must be taken into consideration that paraffin wax mixtures which appear solid at room temperature may also contain varying proportions of liquid paraffin. In the paraffin waxes which are particularly suitable for use according to the invention, the liquid fraction at 40° C. is as high as possible without being 100% at this temperature.
  • DTA differential thermal analysis
  • paraffin wax mixtures have, at 40° C., a liquid fraction of at least 50% by weight, in particular from 55% by weight to 80% by weight, and, at 60° C., a liquid fraction of at least 90% by weight. In addition, it must be ensured that the paraffins contain the smallest possible volatile fractions.
  • Preferred paraffin waxes comprise less than 1% by weight, in particular less than 0.5% by weight, of fractions which can be vaporized at 110° C. and atmospheric pressure. Paraffin waxes which are particularly suitable for use according to the invention can be obtained, for example, under the trade names Lunaflex® from Fuller, and Deawax® from DEA Mineralöl AG.
  • the water-soluble starch or cellulose derivatives which can be used as coating materials include, in particular, starch ethers and cellulose ethers.
  • cellulose ethers are methylcellulose, ethylcellulose, hydroxyethylcellulose, methylhydroxyethylcellulose, methylhydroxypropylcellulose and carboxymethylcellulose, which is normally used as the sodium salt.
  • Suitable as starch is, for example, depolymerized starch.
  • Suitable starch ethers are, for example, carboxymethylstarch, hydroxyethylstarch and methyl-starch.
  • Sodium carboxymethylcellulose and starch have proven to be particularly suitable. It is also particularly advantageous to use gelatin as coating material.
  • Polyvinyl alcohols are not accessible by direct polymerization methods since the base monomer vinyl alcohol required therefor does not exist. Polyvinyl alcohols are therefore produced via polymer-analogous reactions by hydrolysis, but industrially, in particular, by alkali-catalyzed transesterification of polyvinyl acetates with alcohols (for example methanol) in solution.
  • alcohols for example methanol
  • Polyvinyl alcohols which are preferably used according to the invention which are usually supplied commercially as white-yellowish powders or granules, have molar masses in the range from 3000 g/mol to 320,000 g/mol, in particular 8000 g/mol to 200,000 g/mol (corresponding to degrees of polymerization in the range from about 75-8000, in particular about 200 to 5000). They preferably have degrees of hydrolysis of from 20% by weight to 100% by weight, in particular from 30% by weight to 90% by weight.
  • these are completely or partially saponified polyvinyl alcohol esters, in particular polyvinyl acetates, with a residual content of acyl groups, in particular acetyl groups, up to about 80% by weight, in particular from 10% by weight to 70% by weight.
  • the polyvinyl alcohols can be further characterized by quoting the degree of polymerization of the starting polymer, the degree of hydrolysis, the saponification number and/or the solution viscosity. Transformation temperatures of the polyvinyl alcohols are dependent on the acetyl group content, the distribution of the acetyl groups along the chain and the tacticity of the polymers.
  • Completely saponified polyvinyl alcohols have a glass transition temperature of 85° C., the value for partially saponified (87-89%) products being considerably lower at about 58° C.
  • Polyvinyl alcohols which normally have a density of about 1.2-1.3 g/cm 3 , are, depending on the degree of hydrolysis, normally soluble in water and strongly polar organic solvents, such as formamide, dimethylformamide and dimethyl sulfoxide, and they are not attacked by (chlorinated) hydrocarbons, esters, fats and oils.
  • Polyvinyl alcohols are classified as toxicologically acceptable and are biodegradable.
  • Further suitable coating materials are polyethylene glycols which have, for example, a relative molecular mass between 10,000 and 20,000.
  • homo- and copolymeric carboxylates such as polyacrylates, polymethacrylates and in particular copolymers of acrylic acid with maleic acid, preferably those containing about 50% by weight to 10% by weight of maleic acid.
  • the relative molecular mass of these homopolymers is generally between 1000 and 100,000, that of the copolymers is between 2000 and 200,000, preferably 50,000 to 120,000, based on free acid.
  • a particularly preferred acrylic acid-maleic acid, copolymer has a relative molecular mass of from 50,000 to 100,000.
  • Further suitable compounds of this class are copolymers of acrylic acid or methacrylic acid with vinyl ethers, such as vinyl methyl ethers, in which the proportion of acid is preferably at least 50% by weight.
  • a further embodiment of the invention arises through the use of so-called host molecules or compounds which, due to their structure or arrangement, can protect bleach activators which are able to enclose molecules such as said bleach activators optionally in their inside.
  • a preferred cage compound is cyclodextrin.
  • the bleach activator according to formula (I) and cyclodextrin are particularly advantageously used in a molar ratio of from 1:1 to 1:2.
  • polyesters used as coating materials preference is given to those which impart soil-repelling properties to the laundry fibers and which, if present during the washing operation, aid the soil release capacity of the other detergent constituents. These are often referred to as soil release active substances or, due to their ability to give the treated surface of the fibers a soil-repelling property, as soil repellants. The same effect can also be observed when they are used in cleaners for hard surfaces. Due to their chemical similarity to polyester fibers, particularly effective and therefore preferred soil release active substances, which can, however, also exhibit the desired effect with fabrics or surfaces made of another material, are copolyesters which contain dicarboxylic acid units, alkylene glycol units and polyalkylene glycol units.
  • Soil release copolyesters of said type and also their use in detergents have been known for a long time.

  • European patent EP 0 241 985 discloses polyesters which, in addition to oxyethylene and terephthalic acid units, comprise 1,2-propylene, 1,2-butylene and/or 3-methoxy-1,2-propylene groups and glycerol units and are end-capped with C 1 - to C 4 -alkyl groups.
  • European patent specification EP 0 253 567 relates to soil release polymers with a molar mass of from 900 to 9000 of ethylene terephthalate and polyethylene oxide terephthalate, where the polyethylene glycol units have molecular weights of from 300 to 3000 and the molar ratio of ethylene terephthalate to polyethylene oxide terephthalate is 0.6 to 0.95.
  • European patent application EP 0 272 033 discloses polyesters with polypropylene terephthalate and polyoxyethylene terephthalate units which are end-capped at least in part by C 1-4 -alkyl or acyl radicals.
  • European patent EP 0 274 907 describes sulfoethyl end-capped terephthalate-containing soil release polyesters.
  • European patent application EP 0 357 280 soil release polyesters with terephthalate, alkylene glycol and poly-C 2-4 -glycol units are produced by sulfonation of unsaturated end groups.

  • the particles according to the invention have a content of bleach activator according to formula (I) of preferably at least 40% by weight and in particular from 50% by weight to 92% by weight; the coating material is present in the granules preferably in amounts up to 60% by weight, in particular from 3% by weight to 50% by weight and particularly advantageously from 10% by weight to 25% by weight, based on the sum of bleach activator and coating material.
  • the granules can contain small amounts of free water not bound as water of crystallization or in a comparable form. These should be as low as possible, the amounts which may normally be tolerated being up to about 5% by weight. However, the granules preferably contain 0 to 3% by weight of water.
  • the invention further provides a method for producing granules containing enclosed bleach activator according to formula (I) by spraying the bleach activator according to formula (I) present in solid, in particular pulverulent, form, if desired in a mixture with binder and/or solid filler or in the form of preproduced granules, with an organic enclosing material which is liquid or liquefied by heating, where the material to be enclosed is, preferably, kept in motion, for example by being in a fluidized bed, a mixer or granulator.
  • Organic and also inorganic enclosing materials such as the alkali metal or alkaline earth metal salts mentioned, particularly when they are solid at room temperature, can also be applied in this way if they are converted beforehand into a solution or at least a pumpable and sprayable slurry, where water is the preferred solvent or slurrying agent, and if desired the solvent or slurrying agent can then at least partially be removed again subsequently to the enclosure operation by a drying step.
  • the drying step can also, particularly when the enclosure is carried out in a fluidized bed with introduced air at temperatures of preferably 25° C. to 80° C. and in particular 45° C. to 75° C., be carried out at the same time as the enclosure operation.
  • a further embodiment of the method according to the invention consists in introducing the bleach activator according to formula (I) into enclosing material liquefied by heating, cooling the resulting mixture to below the melting point or the softening point of the enclosing material and, during this or subsequently, converting it to granules in a manner known in principle, by, for example, pelleting, pastilling, extrusion or, if desired, grinding.
