the process described in wo 2004 060358 a2 the amount of colorant present in the nanoemulsion was 0 25 g per 100 g of nanoemulsion the nanoemulsion was diluted in water according to a given concentration u00bd or u00bc or u215b or 1 16 the monitoring labels were immersed at 40 u00b0 c in one of the abovementioned is dilute solutions the impregnation time was 30 minutes drying was carried out in a flat position once dried the various labels were washed up to 20 times this being carried out according to the standardized protocol of the standard iso 6330 standard relating to methods for domestic washing and drying for the purpose of tests on textiles after each washing and drying the color of the label was given a numerical value fuchsia pink fuchsia pink 2 lighter pink than fuchsia pink pink light pink light pink 2 lighter pink than light pink pastel pink pastel pink 2 lighter pink than pastel pink pinkish white the sterol was quantitatively determined by reverse phase liquid chromatography with detection in the ultraviolet at 240 nm the linearity of the quantitative determination of the sterol in pure solution was confirmed with sterol solutions prepared from the source of the sterol namely rhodysterol red alga extract known for its excellent lipolytic properties rhodysterol batch 6 06.
