Regulation (EC) No 648/2004 of the European Parliament and of the Council of 31 March 2004 on detergents (Text with EEA relevance)

4.1.2.Inherent Biodegradability TestsU.K.

At least one of the tests referred to below shall be included:

  • method of the Directive 67/548/EEC, Annex V.C.12 (Modified SCAS test),

  • method of the Directive 67/548/EEC, Annex V.C.9 (Zahn-Wellens).

Failure to pass the inherent biodegradability test would indicate potential for persistency which may be considered, in general terms, as sufficient to prohibit the placing on the market of such a surfactant except in cases where the criteria set out in Article 6 indicate that there is no justification for refusing a derogation.
