52An investigation into the domestic laundry habits in EuropeThis method of measuring rinse efficiency is under consideration by workinggroups within the standardization committees IEC SC 59D and CENELECTC 59X.Calculation of the alkalinity is described in IEC 60456:1998 [9]. We haveused a 95 % level of confidence to find if the differences are significant.3.3 Wash performance detergents3.3.1 Test designThe following tables show the detergents selected for each country and thedosage administered. The water hardness used is 14 °dH.Table 3-4 Textile detergents selected from GreeceDetergent Skip Skip Ariel Essential Alpine Skip 5Code detergent G-A G-B G-C G-DType of detergent Tablets Traditional Liquid TabletsDetergent for coloured no no Yes notextiles (yes/no)Dosage 2 tablets 130 mL 75 mL 2 tablets= 82.1 g = 79.0 g = 78.0 g = 78.5 gTable 3-5 Textile detergents selected from The NetherlandsDetergent Ariel Omo Robijn Intensief Ariel ColorCode detergent NL-A NL-B NL-C NL-DType of detergent Tablets Conc. powder Liquid TabletsDetergent for colouredtextiles (yes/no)no no Yes yesDosage 2 tablets 84 mL 60 mL 2 tablets= 86.1 g = 79.0 g = 61.0 g = 84.5 gAs table 3-5 shows, the Netherlands has selected a compact detergent as thecode B detergent, which should have been a traditional detergent. This is becausewe could not find a commonly used traditional detergent in the Netherlands.5 This detergent should have been a Greek detergent for coloured textiles, but we found that theGreek detergent for white textiles have been tested instead.

The test was conducted under fixed conditions,and the results evaluated should be comparable with regard to the differencesbetween the detergents tested.Wash performance of detergents for white textilesDetergent types A and B are compacts and traditional detergents (respectively)which are specifically designed to keep textiles white. Thus we callthem detergents for white textiles. Results are shown in table 3-8.Greece and Spain seem to have the detergents for white textiles with highestwash performance. Both countries are known to use traditional detergentsmost commonly, and it is interesting to see that the Spanish traditional detergenttested has a better wash performance than the compact detergent tested.This is probably the reason why Spanish consumers choose traditional detergentsinstead of compacts, presuming that this is true in general for these two
