- appropriate amounts of the dispersion are made up to 100 ml with ethanol, so that the concentration of 1 g of polymer in 100 ml of solution arises ,
- the K value is measured in a Micro Ubbelohde capillary type M Ic from Schott.
- the droplet size distribution was determined using Particle Size Measurement System for Detecting Liquid Aerosols " Malvern® Master Sizer X” (Malvern Instruments Inc., Southborough MA, USA).
- the measuring system is based on the method of laser light diffraction on the particle, which is used not only for spray analysis (aerosols, pump sprays) but also for sizing
- Solids, suspensions and emulsions in the size range of 0.1 microns to 2000 microns is suitable.
- the aerosol cans were fixed to a fixed holding device before each measurement, thus ensuring that all the aerosols to be tested were measured at exactly the same distance.
- the aerosol was sprayed into the test room.
- the entire particle volume was recorded and evaluated over a test period of 2 s.
- the evaluation contains a tabular representation over 32 class widths from 0.5 .mu.m to 2000 .mu.m and in addition a graphic representation of the Generalchenieren ⁇ distribution.
- this value is between 30 ⁇ m and 80 ⁇ m, depending on the polymer content, valve, spray head geometry, solvent ratio and propellant charge.
- Consolidation (flexural strength): The consolidation of polymeric film formers was measured physically as well as objectively by physical judgment as flexural stiffness of thin strands of hair which were treated with the polymer solution and dried again. In this case, a force transducer determines the force required for bending, while the entire measurement runs under standardized conditions in a climatic room at 65% relative humidity.
- the tests were mit ⁇ in a climatic chamber at 20 0 C and 65% relative humidity means of a train / pressure tester performed.
- the lock of hair was placed symmetrically on two cylindrical rollers of the sample holder. Exactly in the middle of the strand was now bent from above with a rounded punch 40 mm (Bre ⁇ chen of the polymer film).
- the required force was measured with a load cell (50 N) and reported in Newton.
- the values determined were set to those of a commercially available comparative polymer (Amphomer ® LV 71 as standard 100% as given an ⁇ ) in relation.
- the hair tress was in an approximately 37 ° C warm Texapon ® NSO - solution (6ml of Texapon ® NSO (28%) in 11 hot water) for about 15 seconds by ⁇ maliges immersing and squeezing washed. The hair strand was then rinsed and treated again in the same way. Thereafter, the lock of hair was well squeezed out on filter paper and allowed to dry overnight. The dry strand of hair was screwed in and examined for residues.
