• the free-flowing premix had a bulk density of approx. 400 g / l after leaving the mixer and was placed in a twin-screw extrader from Lihotzky and plasticized and extruded under pressure.
• the plasticized premix left the extrader at a pressure of 85 bar through a perforated plate with outlet bores of 0.5, 0.7, 0.85 and 1.2 mm in diameter.
• the extruded strands were chopped to a length / diameter ratio of approx. 1 with a rotating chopper and rounded in a Marume ⁇ zer. After the fine particles ( ⁇ 0.4 mm) and the coarse particles (> 2.0 mm) had been sieved, the extradates had the physical properties listed in Table 2.
• fragrance pearls DUP 1 to DUP 6 produced according to the invention were compared with extrudates of similar composition, in which the perfume oils in question were sprayed onto the extruded and milled particles which had been powdered with finely divided zeolite in a conventional manner.
• the composition of the perfume oils used in the individual fragrance pearls is given in Table 3.
• the fragrance of the product as well as of treated textiles (cotton) was assessed as a subjective scent by perfumers.
• the numerical values in the evaluation table (Table 4) indicate the number of perfumers who rated the respective products or the textiles treated with the respective agent as “more fragrant”. Because a different number of perfumers was present in the different smell tests , the values in the "Perfumers" columns do not always add up to the same value.
• the first block of the first column (product) should therefore be read in such a way that 4 out of 5 perfumers rated the extradates produced according to the invention as more fragrant.
• the results of the smell tests are summarized in Table 4.
