  • Fragrance compounds of the ester type are known e.g. Benzyl acetate, phenoxyethyl isobutyrate, p-tert-butylcyclohexyl acetate, linalyl acetate, dimethylbenzylcarbinylacetate, phenylethylacetate, linalylbenzoate, benzylformate, ethylmethylphenylglycinate, allylcyclohexylpropionate, styrallylpropionate and benzylsalicylate.
  • the ethers include, for example, benzyl ethyl ether, to the aldehydes e.g. the linear alkanals having 8-18 C atoms, citral, citronellal, citronellyloxyacetaldehyde, cyclamen aldehyde, hydroxycitronellal, lilial and bourgeonal, to the ketones e.g.
  • the hydrocarbons mainly include the terpenes such as limonene and pinene.
  • terpenes such as limonene and pinene.
  • fragrances are used, which together produce an attractive fragrance.
  • perfume oils may also contain natural fragrance mixtures such as are available from vegetable sources, e.g. Pine, citrus, jasmine, patchouly, rose or ylang-ylang oil.
  • fragrances can be incorporated directly into the compositions of the invention, but it may also be advantageous to apply the fragrances on carriers, which enhance the adhesion of the perfume on the laundry and provide a slower fragrance release for long-lasting fragrance of the textiles.
  • carrier materials for example, cyclodextrins have been proven, the cyclodextrin-perfume complexes can be additionally coated with other excipients.
  • compositions are water-soluble inorganic salts such as bicarbonates, carbonates, amorphous silicates, or mixtures of these;
  • alkali metal carbonate and / or amorphous alkali silicate especially sodium silicate with a molar ratio of Na 2 O: SiO 2 of 1: 1 to 1: 4.5, preferably from 1: 2 to 1: 3.5, are used.
  • the content of sodium carbonate in the final preparations is preferably up to 40 wt .-%, advantageously between 2 and 35 wt .-%.
  • the content of the sodium silicate (without any special builder properties) is generally up to 10% by weight and preferably between 1 and 8% by weight.
  • a filling or adjusting means can also, for example Sodium sulfate in amounts of 0 to 10, in particular 1 to 5 wt .-% - based on means - be contained
  • the following examples illustrate the process according to the invention for the cold production of liquid detergents.
  • the starting materials were mixed according to Table 1 at different temperatures (30, 23, 5 ° C based on the water in the template) with vigorous stirring and made up the approaches with water of 23 or 5 ° C to 100 parts.
