Definitions

• the essentially water-free premix which is pressed agglomerated preferably has no dust-like components and in particular no particles with particle sizes below 200 ⁇ m.
• those particle size distributions are preferred which have at least 90% by weight of particles with a diameter of at least 400 ⁇ m.
• the washing or cleaning agents or components produced by press agglomeration consist of at least 70% by weight, advantageously at least 80% by weight and, with particular preference, up to 100% by weight spherical or almost spherical (pearl-shaped) particles with a particle size distribution which has at least 60% by weight of particles between 0.8 and 2.0 mm.
• the premix can contain a raw material or a compound which functions as a binding and disintegration aid.
• these binding and disintegration aids serve as lubricants and adhesives which adhere the solid components of the premix to one another and facilitate the passage of the premix through the pressure zone of the press agglomeration apparatus.
• water-soluble binders they also facilitate the redissolution of the press agglomerates, since they act as disintegrants in aqueous liquors.
• the particularly preferred polyethylene glycols include those with relative molecular weights between 2000 and 12000, advantageously around 4000, polyethylene glycols with relative molecular weights below 3500 and above 5000, in particular in combination with polyethylene glycols with a relative molecular weight of around 4000, and such combinations advantageously to more than 50% by weight, based on the total amount of polyethylene glycols, have polyethylene glycols with a relative molecular weight between 3500 and 5000.
• polyethylene glycols which are in the liquid state at room temperature and a pressure of 1 bar can also be used as binders;
• polyethylene glycol with a relative molecular mass of 200, 400 and 600 can also be used as binders;
• these per se liquid polyethylene glycols should only be used in a mixture with at least one further binder, this mixture again having to meet the requirements according to the invention, that is to say having a melting point or softening point of at least above 45 ° C.
• the more volatile fragrances include, in particular, the lower-boiling fragrances of natural or synthetic origin, which can be used alone or in mixtures.
• Examples of more volatile fragrances are alkyisothiocyanates (alkyl mustards), butanedione, limonene, linalool, Linaylacetate and propionate, menthol, Menthone, methyl-n-heptenone, phellandrene, phenylacetaldehyde, terpinylacetate, citral, citronellal.
• the group of polyhydroxy fatty acid amides also includes compounds of the formula (II)
• Suitable organic builder substances are dextrins, for example oligomers or polymers of carbohydrates, which can be obtained by partial hydrolysis of starches.
• the hydrolysis can be carried out by customary processes, for example acid-catalyzed or enzyme-catalyzed. They are preferably hydrolysis products with average molecular weights in the range from 400 to 500,000.
• DE dextrose equivalent
• polyacetals which can be obtained by reacting dialdehydes with polyolcarboxylic acids which have 5 to 7 carbon atoms and at least 3 hydroxyl groups, for example as described in European patent application EP-A-0 280 223.
• Preferred polyacetals are obtained from dialdehydes such as glyoxal, glutaraldehyde, terephthalaldehyde and mixtures thereof and from polyol carboxylic acids such as gluconic acid and / or glucoheptonic acid.
• the enzymes can be adsorbed on carriers and / or embedded in coating substances in order to protect them against premature decomposition.
• the proportion of the enzymes, enzyme mixtures or enzyme granules can be, for example, about 0.1 to 5% by weight, preferably 0.1 to about 2% by weight.
• Table 1 Composition of the spray-dried granules [% by weight]:
• an extrudate E3 was also produced which contained part of the perfume and was also sprayed with the rest of the perfume. This agent was compared with a comparative sex trudate V3, in which the total amount of the perfume was applied by spraying.
