- polyvinyl alcohols are also useful as the wrapping material. These are not accessible by direct polymerization, since the necessary basic monomer vinyl alcohol does not exist. Polyvinyl alcohols are therefore polymer-analogous reactions by hydrolysis, but technically especially by alkali-catalyzed transesterification of polyvinyl acetates with alcohols (preferably methanol) in solution produced.
- alcohols preferably methanol
- Commercially available polyvinyl alcohols which are offered as white-yellowish powders or granules with degrees of polymerization in the range of about 500-2500 (corresponding to molar masses of about 20000-100000 g / mol) have different degrees of hydrolysis of 98-99 wt .-% or 87-89 mole%.

- the polyvinyl alcohols are characterized by the manufacturer by indicating the degree of polymerization of the starting polymer, the degree of hydrolysis, the saponification number or the solution viscosity. Conversion 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. Fully saponified polyvinyl alcohols have a glass transition temperature of 85 ° and a melting point of 228 °.
- Polyvinyl alcohols which normally have a density of about 1.2-1.3 g / cm, are soluble in water and a few highly polar organic solvents such as formamide, dimethylformamide, and dimethylsulfoxide, of (chlorinated) hydrocarbons, esters, fats, depending on the degree of hydrolysis and oils they are not attacked. Polyvinyl alcohols are classified as toxicologically harmless and are at least partially biodegradable. Preferably, polyvinyl alcohols are used which have a saponification number in the range from 20 to 350, in particular in the range from 100 to 300 and particularly preferably from 150 to 250. The degree of polymerization is preferably in the range from 100 to 3000, in particular from 150 to 2000 and particularly preferably from 250 to 500.

- the diameters of the coated PeroxocarbonTexreteilchen are preferably in the range of 100 microns to 1000 microns; Therefore, it starts from correspondingly finely divided Peroxocarbonchurematerial and covers it with the wrapping material.
- a fluidized bed of the peroxycarboxylic acid particles to be coated is sprayed with a solution or slurry, preferably an aqueous solution, of the coating material, the solvent or suspending agent, preferably water, being removed by evaporation and the coated peroxycarboxylic acid particles in the usual manner from the fluidized bed discharges.
- a solution or slurry preferably an aqueous solution
- the solvent or suspending agent preferably water
- an inventive anhydrous liquid detergent or cleaning agent may contain all conventional ingredients in such agents, such as surfactants, solvents, builders, enzymes and other auxiliaries such as soil repellants, thickeners, dyes and perfumes or the like.
- it contains nonionic surfactants and / or organic solvents and optionally anionic surfactants, cationic surfactants and / or amphoteric surfactants.
- the solvents or solvent mixtures used in the liquid phase of the agent are surfactants or at least contain a proportion which corresponds in particular to 10% by weight to 99% by weight of the total solvent to surfactants.
- Surfactants of the sulfonate type, alk (en) ylsulfates, alkoxylated alk (en) ylsulfates, ester sulfonates and / or soaps are preferably used as anionic surfactants.
- Preferred surfactants of the sulfonate type are C -C 3 -alkylbenzenesulfonates, olefinsulfonates, ie mixtures of alkene and hydroxyalkanesulfonates and disulfonates, such as those obtained, for example, from C 1 -C 8 -monoolefins having terminal or internal double bonds by sulfonating with gaseous sulfur trioxide and subsequent alkaline or acidic hydrolysis of the sulfonation obtained.
- Alk (en) ylsulfates are the alkali metal salts and, in particular, the sodium salts of the sulfuric monoesters of the C 1 -C 8 fatty alcohols, for example, coconut fatty alcohol, tallow fatty alcohol, lauryl, myristyl, cetyl or stearyl alcohol or the C 8 -C 20 -oxoalcohols and those half-esters of secondary alcohols of this chain length prefers. Also preferred are alk (en) ylsulfates of said chain length, which contain a synthetic, straight-chain alkyl radical produced on a petrochemical basis.
- C 12 -C 16 alkyl sulfates and C 12 -C 15 - alkyl sulfates and C 4 -C ⁇ 5 alkyl sulfates and C 4 -C ⁇ 6 alkyl sulfates are particularly preferred.
- 2,3-alkyl sulfates which are produced for example in accordance with US Patent No. 3,234,258 or 5,075,041 and can be obtained as commercial products from Shell Oil Company under the name DAN ®, are suitable anionic surfactants.
- sulfuric monoesters of ethoxylated with 1 to 6 moles of ethylene oxide straight-chain or branched C -C 2 ⁇ -alcohols such as 2-methyl-branched C -C ⁇ - alcohols having an average of 3.5 moles of ethylene oxide (EO) or C 1 -C 18 fatty alcohols with 1 to 4 EO, are suitable. Due to their high foaming behavior, they are usually used in detergents only in relatively small amounts, for example in amounts of from 0 to 5% by weight.
- esters of ⁇ -sulfo fatty acids e.g. the sulfonated methyl esters of hydrogenated coconut, palm kernel or tallow fatty acids.
- anionic surfactants are particularly soaps into consideration.
- Particularly suitable are saturated fatty acid soaps, such as the salts of lauric acid, myristic acid, palmitic acid, stearic acid, hydrogenated erucic acid and behenic acid and in particular from natural fatty acids, for.
- coconut, palm kernel or Taigfettklaren derived soap mixtures.
- those soap mixtures are preferred which are composed of 50 to 100 wt .-% of saturated C 2 -C 24 fatty acid soaps and O to 50 wt .-% of oleic acid soap.
- Ethercarboxylic acids are water hardness insensitive and have excellent surfactant properties. Production and use are for example in soaps, oils, fats, waxes 101, 37 (1975); 115, 235 (1989) and surfactants Deterg. 25, 308 (1988).
- Cationic surfactants contain the surface activity of the high molecular weight hydrophobic residue upon dissociation in aqueous solution in the cation.
- the most important representatives of cationic surfactants are the quaternary ammonium compounds of the general formula: (R * R 2 R 3 R 4 N + ) X ⁇ where R 1 is C 1 -C 8 -alk (en) yl, R 2 to R 4 are each independently C n H 2n + ⁇ -p- ⁇ - (Y 1 (CO) R 5 ) p - (Y 2 H) ⁇ , where n stands for integers without 0 and p and x stand for integers or 0. Y and Y independently represent O, N or NH.
- R 5 denotes a C 3 -C 23 -alk (en) yl chain.
- X is a counterion, which is preferably selected from the group of halides, alkyl sulfates and alkyl carbonates. Particularly preferred are cationic surfactants in which the nitrogen group is substituted by two long acyl and two short alk (en) yl radicals.
- Amphoteric or ampholytic surfactants have a plurality of functional groups which can ionize in aqueous solution and, depending on conditions of the medium, impart anionic or cationic character to the compounds (see DIN 53900, July 1972). Near the isoelectric point (around pH 4), the amphoteric surfactants form internal salts, making them difficult or insoluble in water. Amphoteric surfactants are subdivided into ampholytes and betaines, the latter being present in solution as zwitterions. Ampholytes are amphoteric electrolytes, ie, compounds that have both acidic and basic hydrophilic groups and thus behave acidic or basic depending on the condition. As Betaine refers to compounds having the atom grouping R 3 N + -CH 2 -COO ⁇ , show the typical properties of zwitterions.
- the nonionic surfactants used are preferably alkoxylated and / or propoxylated, in particular primary, alcohols having preferably 8 to 18 C atoms and on average 1 to 12 moles of ethylene oxide (EO) and / or 1 to 10 moles of propylene oxide (PO) per mole of alcohol.
