Description of key information

EC10 (21 d, mortality) = 1.76 mg a.i./L for Daphnia magna (OECD 202 part II) (read-across)

Key value for chemical safety assessment

Additional information

There are no data available on long-term toxicity of aquatic invertebrates ofReaction products of D-Glucose, n-Butanol and C10-12 (even numbered) alcohols.However, there are reliable data for category member substances which are considered suitable for read-across based on a category approach. This read-across is in accordance with Regulation (EC) No. 1907/2006 Annex XI, 1.5 and justified in detail in the overall summary (IUCLID Chapter 6.1) and within the category justification attached in IUCLID Section 13. In this case of read-across, the best suited (highest degree of structural similarity, nearest physico-chemical properties) read-across substance was used for the assessment. Nevertheless, as it can be seen in the data matrix of the category justification in IUCLID Section 13 and the overall summary (IUCLID Chapter 6.1), all reliable data in the category support the hazard assessment of each category member by showing a consistent pattern of results.

The long-term effects of the category member and component of the substance D-Glucopyranose, oligomeric, C10-16-alkyl glycosides towards aquatic invertebrates were evaluated in a 21 d test with Daphnia magna according to OECD guideline 202 part II (Henkel, 1995). The test design was semi-static with a daily renewal of the test substance and growth medium. Nominal test concentrations of 1, 2, 4, 8 and 16 mg/L were applied. The test exhibited an EC10 (21 d) of 1.76 mg a.i./L for mortality and a NOEC (21 d) of 2 mg a.i./L for reproduction, respectively.
