Additional information
Acute oral toxicity
In different studies, Tetraoctylammonium Bromide(14866-33-2),has been investigated for acute oral toxicity to a greater or lesser extent. Often are the studies based on in vivo experiments and estimated data in rodents, i.e. most commonly in rats Tetraoctylammonium Bromide(14866-33-2) The predicted data using the OECD QSAR toolbox has also been compared with the experimental studies.
In a prediction done by SSS (2017) using the OECD QSAR toolbox with log kow as the primary descriptor, the acute oral toxicity was estimated for Tetraoctylammonium Bromide(14866-33-2),LD50 was estimated to be 2294.15mg/kg bw, when female wistar rats were exposed with Tetraoctylammonium Bromide(14866-33-2) orally.
Based on the QSAR prediction done using the Danish (Q)SAR Database, the LD50 was estimated to be 5500mg/kg bw on rat for Tetraoctylammonium Bromide(14866-33-2) having Reliability Index: 0.52(moderate prediction quality)
Based on the QSAR prediction done using the Danish (Q)SAR Database, the LD50 was estimated to be 3100mg/kg bw on mouse for Tetraoctylammonium Bromide(14866-33-2) having Reliability Index: 0.76(high prediction quality).
In experimental study given by HSDB (TOXNET Toxicology Data Network, 2017)
on structurally similar read across substancewith 1-Octadecanaminium- N,N-dimethyl-N-{3- (trimethoxysilyl)propyl}- chloride (27668-52-6). In acute oral toxicity study, rats were treated with1-Octadecanaminium- N,N-dimethyl-N-{3- (trimethoxysilyl)propyl}- chloride in the concentration of 5000 mg/kg bw orally. No mortality observed in treated rats at 5000 mg/kg bw. Therefore,LD50 was considered to be > 5000 mg/kg bw when rats were treated with 1-Octadecanaminium- N,N-dimethyl-N-{3- (trimethoxysilyl)propyl}- chloride orally.
In another experimental study given by IFA GESTIS (GESTIS SUBSTANCE Database (information system in hazardous substance of the Berufsgenossenscheftn),2017) on structurally similar read across substanceDimethyldioctadecylammonium Chloride (DODMAC) (CAS No: 107-64-2).An acute oral toxicity study of Dimethyldioctadecylammonium Chloride (DODMAC) (CAS No: 107-64-2) was carried out in 10 male and 10 female rats to determine its LD50. The substance, formulated as 20% solution in water, was administered at a various dose concentration by oral route. The observation period was 12 days. The clinical signs of toxicity like Depressions of spontaneous movement, diarrhea, piloerection, abdominal distention were observed in treated rats. No mortality occurred after application of 6,900 mg/kg to 10 males, no mortality occurred after application of 8,300 mg/kg to 10 females, 14,400 mg/kg killed 7/8 males and 6/9 females, deaths were observed on days 1-7. 50% mortality was observed at dose For male: 11,300mg/kg bw and For female: 13000mg/kg bw . Thus, LD 50 value was considered to be For male: 11,300mg/kg bw and For female: 13000mg/kg bw When male and female rats were treated with Dimethyldioctadecylammonium Chloride (DODMAC) (CAS No: 107-64-2) orally.
Thus, based on the above studies and predictions on Tetraoctylammonium Bromide(14866-33-2)and its read across substances, it can be concluded that LD50 value is 2294.15mg/kg bw. Thus, comparing this value with the criteria of CLP Tetraoctylammonium Bromide(14866-33-2) can be “Not classified” for acute oral toxicity.
Acute dermal toxicity
In different studies,Tetraoctylammonium Bromide(14866-33-2),has been investigated for acute dermal toxicity to a greater or lesser extent. Often are the studies based on in vivo experiments and estimated data in rodents, i.e. most commonly in rabbits forTetraoctylammonium Bromide(14866-33-2),The predicted data using the OECD QSAR toolbox has also been compared with the experimental studies.
In a prediction done by SSS (2017) using the OECD QSAR toolbox with log kow as the primary descriptor, the acute dermal toxicity was estimated for Tetraoctylammonium Bromide (14866-33-2). LD50 was estimated to be 4805.16mg/kg bw. When male and female New Zealand White rabbits were exposed with Tetraoctylammonium Bromide (14866-33-2) by dermal application.
In experimental study given byHSDB (TOXNET Toxicology Data Network, 2017 )on structurally similar read across substance 1-Octadecanaminium- N,N-dimethyl-N-{3- (trimethoxysilyl)propyl}- chloride (27668 -52 -6). In acute dermal toxicity study, rabbits were treated with1-Octadecanaminium- N,N-dimethyl-N-{3- (trimethoxysilyl)propyl}- chloride (27668 -52 -6) in the concentration of 2000 mg/kg bw dermally. No mortality observed in treated rabbits at 2000 mg/kg bw. Therefore,LD50 was considered to be >2000 mg/kg bw when rabbits were treated with1-Octadecanaminium- N,N-dimethyl-N-{3- (trimethoxysilyl)propyl}- chloride dermally.
Also these results are further supported by experimental study given by European Chemicals Bureau (ECB) (European union Risk Assessment Report - Dimethyldioctadecylammonium Chloride (DODMAC), vol.14, 2009)on structurally similar read across substance Dimethyldioctadecylammonium Chloride (DODMAC)(107-64-2) .Acute dermal toxicity study was done in 5male and 5 female rats using test material Dimethyldioctadecylammonium Chloride (DODMAC)(107-64-2).The test substance in dose concentration 2000mg/kg bw as suspension prepared in water was applied occlusively to the skin. No mortality was observed at dose 2000mg/kg bw but skin dryness was observed. No pathologic signs were detected at necropsy. HenceLD50 was considered to be >2000mg/kg body weight. When rats were treated with Dimethyldioctadecylammonium Chloride (DODMAC)(107-64-2) by dermal application.
Thus, based on the above studies and predictions on Tetraoctylammonium Bromide (14866-33-2)and its read across substances, it can be concluded that LD50 value is 4805.16 mg/kg bw.Thus, comparing this value with the criteria of CLP Tetraoctylammonium Bromide (14866-33-2) can be “Not classified” for acute dermal toxicity.
Justification for classification or non-classification
Thus, comparing this value with the criteria of CLP Tetraoctylammonium Bromide (14866-33-2) can be “Not classified” for acute oral and dermal toxicity.
