54An <strong><strong>in</strong>vestigation</strong> <strong>in</strong>to the <strong>domestic</strong> <strong>laundry</strong> <strong>habits</strong> <strong>in</strong> Europetypes. The traditional detergent (Ariel Alp<strong>in</strong>e) tested is also the only detergentfrom Spa<strong>in</strong> which was probably developed outside <strong>of</strong> Spa<strong>in</strong> (by Proctor &Gamble, Switzerl<strong>an</strong>d). Greece has a good wash perform<strong>an</strong>ce for the compactdetergent, but the traditional detergent has signific<strong>an</strong>t lower wash perform<strong>an</strong>ceth<strong>an</strong> the Sp<strong>an</strong>ish traditional detergent. At 30 °C they are <strong>in</strong> fact signific<strong>an</strong>tlydifferent. Greek consumers tend to use a much higher wash temperatureth<strong>an</strong> the Sp<strong>an</strong>ish, <strong>an</strong>d this detergent might not be designed for low temperatureswhen produced for the Greek market. And as we see <strong>in</strong> the results,the perform<strong>an</strong>ce <strong>of</strong> the Greek traditional detergent is highly dependent ontemperature.Table 3-8 Average wash perform<strong>an</strong>ce <strong>of</strong> compacts <strong>an</strong>d traditional detergents30 °C 40 °CCompact (A) Traditional (B) Compact (A) Traditional (B)Ref A* - 59.81 (± 1.21) % - 62.39 (± 0.62) %Greece 61.06 (± 1.58) % 58.46 (± 1.43 6 ) % 63.59 (± 1.03) % 63.02 (± 0.68) %NL 59.35 (± 1.02 7 ) % 59.62 (± 1.75 8 ) % 62.11 (± 0.52) % 62.57 (± 0.71) %Norway 57.86 (± 1.04) % 59.32 (± 2.00 9 ) % 61.49 (± 1.00) % 61.08 (± 0.28) %Spa<strong>in</strong> 57.28 (± 2.48 10 ) % 61.22 (± 0.87) % 61.05 (± 1.85) % 63.24 (± 0.87) %The Norwegi<strong>an</strong> detergents have relatively low wash perform<strong>an</strong>ce at both temperatures.The results for both Norwegi<strong>an</strong> detergents at 40 °C are <strong>in</strong> fact comparableto the wash perform<strong>an</strong>ce for the Sp<strong>an</strong>ish traditional detergent at30 °C.

For the Sp<strong>an</strong>ish compactdetergent we detect a signific<strong>an</strong>t low effect on the prote<strong>in</strong>/tea soil (wFk 106 Only four cycles are evaluated.7 Only four cycles are evaluated.8 Only four cycles are evaluated.9 Only three cycles are evaluated.10 Only four cycles are evaluated.
