- Endpoint:
- toxicity to reproduction
- Remarks:
- other: Screening
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- Work performed to OECD guidelines in 2009 and approved by the US Environmental Protection Agency Statement in report claiming the data covers range of alklyimines; specifically, "sodium and potassium salts of N-alkyl (C8-C18)-beta-iminodipropionic acid where the C8-C18 is linear and may be saturated and/or unsaturated, (CAS Reg. Nos. 110676-19-2, 3655-00-3, 61791-56-8, 14960-06-6, 26256-79-1, 90170-43-7, 91696-17-2, and 97862-48-1) [Ref 40 CFR Part 180, Federal Register Volume 76, number 24, 4 February 2011'
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 422 (Combined Repeated Dose Toxicity Study with the Reproduction / Developmental Toxicity Screening Test)
- GLP compliance:
- yes
- Limit test:
- no
- Species:
- rat
- Strain:
- other: HanRcc:WIST (SPF)
- Sex:
- male/female
- Route of administration:
- oral: gavage
- Duration of treatment / exposure:
- Dosing began 14 days before mating and continued for 28 days for males and for day four of lactation for females

Body weights
Blood sampling
Body temperature (during FOB) - Dose descriptor:
- NOAEL
- Effect level:
- > 43 mg/kg bw/day (nominal)
- Based on:
- act. ingr.
- Sex:
- male/female
- Basis for effect level:
- other: Reduced weight gain, adaptive changes to liver and kidneys
- Reproductive effects observed:
- not specified
- Conclusions:
- No treatment-related effects on litter size or survival were observed. No treatment-related effects on body weight were observed in offspring. Body weight gain was slightly decreased in males and females at 160 and 600 mg/kg/day, but there was no dose response.
No findings were observed on macroscopic examination of the offspring. The reproductive/developmental LOAEL for Sodium coco β-iminodipropionate in rats is not established.
The reproductive/developmental NOAEL is 600 mg/kg bw/day, the highest dose tested, in males and females.
