Description of key information

The biodegradation in water was investigated following the OECD Guideline 301 F (Ready Biodegradability: Manometric Respirometry Test), the EU Method C.4-D (Determination of the "Ready" Biodegradability - Manometric Respirometry Test) and Regulation (EC) No. 648/2004 of the European Parliament and the Council of 31 March 2004 on detergents.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

Eucarol AGE 91/S ( Sulfonation products of (esterification products of C9-11 (branched and linear) alkyl-(mono-, di- and tri-)glycosides with maleic anhydride) with disodium sulfite ) was used as supporting substance due to the structural analogy.

It can be expected a similar structural features.

The results show that "Sulfonation products of (esterification products of C9-11 (branched and linear) alkyl-(mono-, di- and tri-)glycosides with maleic anhydride) with disodium sulfite" attained a maximum mean level of biodegradation (based on the BOD:COD ratio) of 63%.

More than 60% degradation was achieved within 28 days, so the substance can be classified as readily biodegradable .
