- such formulations typically contain water-insoluble, quaternary ammonium compounds usually having at least two long-chain alkyl or alkenyl chains. Due to their better biodegradability, quaternary ammonium compounds containing long chain alkyl or alkenyl groups interrupted by functional groups such as carboxy groups have gained interest.

- the viscosities were measured on an "MCR 302" rheometer from Anton Paar according to DIN EN ISO 3219: 1994 and DIN 53019, using a cone-plate system (cone CP50-2) with an opening angle of 2°.
- the device was calibrated using standard oil from the Physikalisch-Technische Bundesweg with standard oil 10000.
- the measurement temperature is 25.00°C +/- 0.05°C, the measurement time is 3 minutes
- the measurement uncertainty of the dynamic viscosity is 1.5%
- the shear rate gradient was selected as a function of the viscosity and is shown separately for each viscosity specification.
- the amine number indicates how many mmol of KOH are equivalent to one gram of the substance to be determined.
- the amine number is determined according to DIN 16945 version 1989-03.
- the polydimethylsiloxane (P-1) containing aminoalkyl groups used in the test examples is a mixed hydroxy/methoxydimethylsilyl-terminated copolymer of aminoethylaminopropylmethylsiloxane and dimethylsiloxane units with a viscosity of 982 mPas (at 25° C. and at a shear rate of 10 1/s) and an amine number of 0.287 mmol/g.
- the silicate compound (Dl) used in the test example is a mixture of tetraethoxysilicate of general formula VI and a polysilicate compound having 2 units of general formula VII and 1 to 7 units of general formula VIII, where R 10 is an ethyl radical with a SiC ⁇ content of 40 wt .-%.
- Emulsion E_1 contains 17% by weight of the film-forming organopolysiloxane Al.
- Emulsion E2 contains 17% by weight of the film-forming organopolysiloxane A2.
- Example 3 Oil-in-water emulsion (not according to the invention) of a linear organopolysiloxane VE3:
- Emulsion VE3 does not contain any film-forming organopolysiloxane.
- compositions Zl_, Z2 (according to the invention) containing
- the formulations are produced by heating the water to 50.degree.
- the cationic surfactant previously melted at 50° C. and stirred intensively is added at this temperature with intensive stirring. Stirring is continued until a homogeneous mixture results.
- the mixture is cooled to 30° C. and the oil-in-water emulsion E_1, E2 or VE3 and other ingredients are added.
- VZ4 only the cationic surfactant and other ingredients are formulated.
- compositions ZI, Z2, VZ3 and VZ4 are diluted with demineralized water to 2000 ml of the use concentration.
- a black, 100% polyester fabric with a grammage of 270 g/m 2 is used.
- the fabric is pretreated by being prewashed in a washing machine (Miele Softtronic W 1935) at 40° C., main wash program without a detergent. It is then punched out into circles with a diameter of 113 mm. The edges are melted off with a flame to prevent fraying.
- a washing machine Miele Softtronic W 1935
- the punched-out polyester fabrics are pretreated with the diluted compositions Zl_, Z2, VZ3 or VZ4 by placing one fabric flat in a beaker with 19 ml of the diluted composition Zl_, Z2, VZ3, VZ4 or just water as a blank (BL ) stirred by hand, squeezed between two rollers and line dried overnight. Finally, the fabric is ironed with a standard iron (approx. 20 seconds, synthetic program).
- the tests are carried out in a Linitest device (from Hanau). To do this, 200 ml of a washing liquid (4 g of Ariel liquid detergent are dissolved in one liter of water), 20 steel balls and a pretreated polyester fabric are placed in a metal beaker and treated for 90 minutes at 60° C. in the Linitester device.
- a washing liquid 4 g of Ariel liquid detergent are dissolved in one liter of water
- 20 steel balls and a pretreated polyester fabric are placed in a metal beaker and treated for 90 minutes at 60° C. in the Linitester device.
- the washing liquid is filtered off through a Büchner filter with a round paper filter (from VWR, 55 mm in diameter, pore size: 31-50 ⁇ m).
- the tissue is rinsed with 100 ml of water and the rinse water is filtered through the same filter.
- the filter paper is photographed and the number of microfibers filtered off is evaluated electronically (Image editing software ImageJ); Output as area occupied by the microfibers on the filter paper.
- the result is the average of twelve individual measurements.
- Table 2 clearly shows that when compositions Z1_ and Z2 are used, the release of microfibers from the polyester fabric is reduced compared to the blank value BL (no finish) or VZ4 (finish with only the cationic surfactant).
- VZ3 which contains no film-forming polysiloxane, significantly more microfibers are released compared to the blank value BL and when using the compositions ZI and Z2.
