Endpoint summary
Administrative data
Key value for chemical safety assessment
Effects on fertility
Description of key information
No data were available for the registered substance, but key read across data from Butanedioic acid, 2(or 3)-sulfo-, 4-[2-[(1- oxo(C12-C18(even numbered) and C18 unsaturated)alkyl))amino]ethyl]esters, disodium salts were available from a combined repeated dose and reproduction/developmental toxicity study acccording to OECD 422 at doses of 100, 300 and 1000 mg active ingredient/kg bw/day. The application started two weeks before mating on test day one and ended on the day or one day before sacrifice. Day of sacrifice was on test day 37 for the male rats and between lactation day 4 and 7 for the female rats.
Effects on the parental generation (general toxicity) : No test item-related premature death was noted in any treatment group (100, 300 and 1000 mg test item/kg bw/day). No signs of clinical toxicity were noted for the male and female rats of the low and intermediate dose groups (100 and 300 mg test item/kg bw/day). A slightly increased salivation was noted in one male rat, no further signs of clinical toxicity were noted for the male and female rats of the high dose group (1000 mg test item/kg bw/day). A slight reduction in body weight was noted for the male and female rats of the high dose group (1000 mg test item/kg bw/day). For the male rats the reduction in body weight was noted from test day 8 (4.4%) until test day 36 (5.5%) and for the female rats from gestation day 0 (7.6%) until lactation day 4 (9.5%). The body weight at autopsy was reduced accordingly.
Effects on reproduction parameters and organs: No test item-related influence was noted on the reproduction parameters in any treatment group (100, 300 and1000 mg/kg bw/day). Microscopic examination revealed no changes in the reproductive organs from the male and female rats of the high dose group (1000 mg/kg bw/day).
Effects on the F0-generation: NOAEL: 300 mg/kg bw/day, p.o.
Effects on reproductive toxicity: NOAEL:: >=1000 mg/kg bw/day, p.o.
Effect on fertility: via oral route

Additional information
In a key combined repeated dose and reproduction/development study according to OECD guideline 422 (LPT, 2013b) read-across sbustance Butanedioic acid, 2(or 3)-sulfo-, 4-[2-[(1- oxo(C12-C18(even numbered) and C18 unsaturated)alkyl))amino]ethyl]esters, disodium salts was administeredorally by gavage to rats at dose levels of 100, 300 and 1000 mg active ingredient/kg bw/day. The application started two weeks before mating on test day one and ended on the day or one day before sacrifice. Day of sacrifice was on test day 37 for the male rats and between lactation day 4 and 7 for the female rats.

Effects on developmental toxicity
Description of key information
No data were available for the registered substance, but key read across data fromButanedioic acid, 2(or 3)-sulfo-, 4-[2-[(1- oxo(C12-C18(even numbered) and C18 unsaturated)alkyl))amino]ethyl]esters, disodium saltswere available from a conbined repeated dose and reproduction/dvelopmental toxicity study acccording to OECD 422 at doses of100, 300 and 1000 mg active ingredient/kg bw/day. The application started two weeks before mating on test day one and ended on the day or one day before sacrifice.

No test item related influence was noted for the male and female rats of all treatment groups (100, 300 and 1000 mg/kg bw/day) during the observational and functional (grip strength and spontaneous motility) neurological screenings.
A slight reduction in body weight was noted for the male and female rats of the high dose group (1000 mg/kg bw/day). For the male rats the reduction in body weight was noted from test day 8 (4.4%) until test day 36 (5.5%) and for the female rats from gestation day 0 (7.6%) until lactation day 4 (9.5%).

Effects on the F0-generation
NOAEL (no-observed-adverse-effect level): 300 mg/kg bw/day, p.o.

Justification for classification or non-classification
As there was no indication for reproductive potential, classification for genotoxicity is not warranted according to CLP (No. 1272/2008 of 16 December 2008).
