Administrative data
- Endpoint:
- developmental toxicity
- Type of information:
- not specified
- Adequacy of study:
- key study
- Study period:
- 1994-05-05 to 1994-05-31
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- GLP study according to OECD TG 414 with restrictions. To address toxicological endpoints as part of the REACH registration of Amyl Salicylate (Target Substance) it is proposed to read-across to Cyclohexyl Salicylate (Source Substance). The use of read-across works within the spirit of REACH and the stated aim of the legislation to reduce animal testing where possible. The Target Substance and Source Substance have been characterised using the categories and databases present in the OECD [Q]SAR Toolbox. From the profiling, it can be seen that the two substances share structural similarities and also ‘mechanistic action’ similarities which are both general and endpoint specific. Therefore, read across is justified.
- Justification for type of information:
- The justification for read across from Cyclohexyl Salicylate is attached in section 13.2 (Other assesment report).

OTHER: foetuses were sexed, weighed individually including placentae, examined for gross external abnormalities, half of the foetuses from each litter was fixed in Bouin's solution in order to examine viscera and brain by Wilson's slicing technique, remaining foetuses from each litter were placed in a solution of potassium hydroxide for clearing and were stained with alizarin red and skeletons were examined and preserved - Ovaries and uterine content:

- Soft tissue examinations: Yes: No data
- Skeletal examinations: Yes: half per litter
- Head examinations: Yes: half per litter - Statistics:
- If the variables could be assumed to have a normal distribution, the Dunnett-test based on a pooled variance was applied for the comparison of the treated groups and the control group. The Steel test was applied when the variables were assumed to be not normally distributed. Fisher's Exact test for 2x2 tables was applied if the variables were dichotomised without loss of information (Bonferroni-Holm corrected).

- Pre-implantation loss, post-implantation loss, mean numbers of resorption, embryonic deaths and total foetuses

To address toxicological endpoints as part of the REACH registration of Benzyl Salicylate (Target Substance) it is proposed to read-across to Cyclohexyl Salicylate (Source Substance).
The use of read-across works within the spirit of REACH and the stated aim of the legislation to reduce animal testing where possible.
The Target Substance and Source Substance have been characterised using the categories and databases present in the OECD [Q]SAR Toolbox. From the profiling , it can be seen that the two substances share structural similarities and also ‘mechanistic action’ similarities which are both general and endpoint specific.

Applicant's summary and conclusion
- Conclusions:
- Daily oral administration of the substance to pregnant Sprague-Dawley rats at doses of 40, 120 and 360 mg/kg bw/day from gestation day 6 to 15 did not cause maternal or foetal toxicity or teratogenic effects. The NOAEL in the study was 360 mg/kg bw/day.
- Executive summary:
The potential embryotoxic and teratogenic effects of the substance cyclohexyl salicylate in the rat was studied under GLP in accordance with OECD TG 414. The substance was dissolved in arachidis oil and administered at a constant volume of 5 mL/kg body weight at doses of 0 (vehicle control), 40, 120 and 360 mg/kg bw/day to pregnant female rats from gestation day 6 to 15. All dams were sacrificed on gestation day 20 and the foetuses removed by Cesarean section. At necropsy the dams were examined macroscopically and foetuses were weighed, sexed and examined for visceral and skeletal abnormalities. The dams tolerated the applied dose levels up to 360 mg/kg bw/da without mortality. No compound related symptoms were observed in all treatment groups. Maternal body weight gain was not affected by treatment. No treatment related abnormalities were found at necropsy of the females. All dams had viable foetuses. Pre-implantation loss, post-implantation loss, mean numbers of resorptions, embryonic deaths and total number of foetuses were not affected by treatment. Mean foetal placental and uterus weights were not affected by treatment and the sex ratio was comparable in all groups. No treatment-related foetal abnormalities were found and there were no differences in the reproduction parameters between the groups. The examined foetuses showed no treatment related malformations. Skeletal variations and ossifications and visceral variations were similar in the control group and the treated groups. The NOAEL for maternal toxicity, embryotoxicity and teratogenicity was 360 mg/kg bw/day.
