Description of key information
Since experimental data for sodium lauroyl lactylate (SLL) are partially lacking, read-across from sodium isostearoyl lactylate (ISL) was applied for two trophic levels (fish, algae). For daphnia an acute toxicity study according to OECD test guideline 202 (2004) was conducted with the target substance.
Three trophic levels (fish, daphnia, algae) are covered by the acute toxicity data set. No chronic data are available. Algae were observed to be the most sensitive species. The 72-h ErC50 determined according to OECD test guideline 201 (2011) was higher than 14.4 mg/L (mean measured, maximum achievable concentration of the read-across partner ISL). Stoichiometric conversion results in an SLL-related ErC50 of > 11.7 mg/L (unbounded).
An activated sludge respiration inhibition test according to OECD 209 resulted in an EC50 of > 1000 mg/L and a NOEC of ≥ 1000 mg/L. There was no significant inhibition of bacterial respiration by the test item up to and including a nominal concentration of 1000 mg per litre. Since ISL shows no significant inhibition of bacteria respiration, neither any toxic effects of SLL on STPs is expected, by way of read-across.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
