Description of key information
Based on the prediction done using the OECD QSAR toolbox version 3.4 with log kow as the primary descriptor and considering the five closest read across substances, gene mutation was predicted for Butyl O-acetylricinoleate (IUPAC name: butyl 12-acetoxyoctadec-9-enoate). The study assumed the use of Salmonella typhimurium strain TA 1535, TA 1537, TA 98, TA 100 and TA 102 with S9 metabolic activation system. Butyl O-acetylricinoleate did not induce gene mutation in Salmonella typhimurium strain TA100 in the presence of S9 metabolic activation system and hence is predicted to not likely classify as a gene mutant in vitro.
Based on the predicted result it can be concluded that the substance is considered to not toxic as per the criteria mentioned in CLP regulation.

Additional information
Gene mutation in vitro:
Prediction model based estimation and data from two read across chemicals were reviewed to determine the mutagenic nature of Butyl O-acetylricinoleate (IUPAC name: butyl 12-acetoxyoctadec-9-enoate). The studies are as mentioned below:
Based on the prediction done using the OECD QSAR toolbox version 3.4 with log kow as the primary descriptor and considering the five closest read across substances, gene mutation was predicted for Butyl O-acetylricinoleate (IUPAC name: butyl 12-acetoxyoctadec-9-enoate). The study assumed the use of Salmonella typhimurium strain TA 1535, TA 1537, TA 98, TA 100 and TA 102 with and without S9 metabolic activation system. Butyl O-acetylricinoleate did not induce gene mutation in Salmonella typhimurium strain TA 1535, TA 1537, TA 98, TA 100 and TA 102 in the presence and absence of S9 metabolic activation system and hence is predicted to not likely classify as a gene mutant in vitro.
Ishidate et al (Food and chemical toxicology, 1984) discussed gene mutation toxicity study to determine the mutagenic nature of 80 -90% structurally similar read across chemical Methyl acetyl ricinoleate (RA CAS no 140 -03 -4, IUPAC name: methyl 12-acetoxyoctadec-9-enoate). The study was performed using S. typhimurium strains TA92, TA1535, TA100, TA1537, TA94 and TA98 with and without S9 metabolic activation system. The test was performed as per the preincbation assay at six different concentration with 10mg/plate being the maximum concentration. Preincubation was performed for 20 mins and the exposure duration was for 48 hrs. The result was considered positive if the number of colonies found was twice the number in the control (exposed to the appropriate solvent or untreated). Methyl acetyl ricinoleate failed to induce a doubling of revertant colonies over the control using S. typhimurium strains TA92, TA1535, TA100, TA1537, TA94 and TA98 in the presence and absence of S9 metabolic activation system and hence is not likely to classify as a gene mutant in vitro.
In the same study by Ishidate et al (1984), Chromosomal aberration study was performed to determine the mutagenic nature of Methyl acetyl ricinoleate. The cells were exposed to the test material at three different doses with 4 mg/mL being the maximum concentration for 24 and 48 hr. Colcemid (final concn 0.2µg/ml) was added to the culture 2 hr before cell harvesting. The cells were then trypsinized and suspended in a hypotonic KCI solution (0.075 M) for 13 min at room temperature. After centrifugation the cells were fixed with acetic acid-methanol (1:3, v/v) and spread on clean glass slides. After air-drying, the slides were stained with Giemsa solution for 12-15 min. A hundred well-spread metaphases were observed under the microscope. In the present studies, no metabolic activation systems were applied. The incidence of polyploid cells as well as of cells with structural chromosomal aberrations such as chromatid or chromosome gaps, breaks, exchanges, ring formations, fragmentations and others, was recorded on each culture plate. Untreated cells and solvent-treated cells served as negative controls, in which the incidence of aberrations was usually less than 3.0%. The results were considered to be negative if the incidence was less than 4.9%, equivocal if it was between 5.0 and 9.9%, and positive if it was more than 10.0%. Methyl acetyl ricinoleate did not induce chromosomal aberration in chinese hamster fibroblast cell line CHL and hence is not likely to classify as a gene mutant in vitro.
Another study was performed by Zeiger at al ( Environmental Mutagenesis, 1985) to determine the mutagenic nature of 50 -60% structurally similar read across chemical. Bacterial reverse mutation assay was performed for the test chemical Di(2-ethylhexy1)adipate (RA CAS no 103 -23 -1, IUPAC name: Bis (2-ethylhexyl) adipate) using Salmonella typhimurium strains TA100, TA1535, TA98, TA1537 with and without rat and hamster liver S9 mix. The study was performed using the preincubation protocol at five dose levels up to 10 mg / plate with incubation period of 48 hrs in the presence and absence of S9 mix.The final dose level selection was based on the results of a preliminary range-finding study conducted with TA100 in the presence and absence of S-9. No mutagenic response was noted for the test compound in the preliminary dose range finding study and the main study performed. Di(2-ethylhexy1)adipatefailed to induce mutation in the Salmonella typhimurium strain TA100, TA1535, TA98, TA1537 with and without rat and hamster liver S9 mix and hence is negative for gene mutation in vitro and hence is not likely to classify for gene mutation in vitro.
Based on the information summarized for the target chemical and its read across, Butyl O-acetylricinoleate (IUPAC name: butyl 12-acetoxyoctadec-9-enoate) does not exhibit gene mutation in vitro. Thus the chemical is not likely to be a gene mutant in vitro as per the criteria mentioned in CLP regulation.
Justification for classification or non-classification
Based on the information summarized for the target chemical and its read across, Butyl O-acetylricinoleate (IUPAC name: butyl 12-acetoxyoctadec-9-enoate) does not exhibit gene mutation in vitro. Thus the chemical is not likely to be a gene mutant in vitro as per the criteria mentioned in CLP regulation.
