Test animals
- Species:
- rat
- Strain:
- Sprague-Dawley
- Sex:
- male
- Details on test animals or test system and environmental conditions:
- Five male SpragueDawley derived albino rats from Hilltop Lab Animals, Inc., weight ranging from 200 to 265 grams.
Food was witheld from the rats for approximately 18 hours prior to dosing. Following dosing, food consisting of PURINA LABORATORY CHOW and
water were available ad libitum. The rats were housed in groups in stainless steel wire mesh cages suspended above the droppings. The animals were housed under a 12-hour light/12-hour dark cycle. The rats were acclimated to the laboratory at least seven days prior to dosing and were
individually identified by numbered ear tags and tail marks with permanent ink.
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- unchanged (no vehicle)
- Details on oral exposure:
- The test sample was administered by esophageal intubation to five groups, each composed of five male Sprague-Dawley derived albino rats from
Hilltop Lab Animals, Inc., weight ranging from 200 to 265 grams. Four groups were treated on April 1, 1981, and the fifth group was treated on April 8, 1981. The sample was administered undiluted at dosage levels of 0.464, 1.00, 2.15, 4.64, and 10.0 grams per kilogram of body weight using an
average density value of 1.036 g/ml for administration on a sample volume basis. - Doses:
- 0.464, 1.00, 2.15, 4.64, and 10.0 grams per kilogram of body weight
- No. of animals per sex per dose:
- 5
- Details on study design:
- All animals were observed closely for gross signs of systemic toxicity and mortality at one and one-half to two hours, three and three-quarter to four and one-quarter hours, and give and one-half to six hours post administration during the day of dosing, and at least once daily thereafter for a
total of 14 days. Gross necropsies were performed on the animals that died. At the end of the 14-day observation period the surviving rats were
weighed, sacrificed by C02 inhalation and gross necropsies were performed. Statittical analysis of the mortality data was by the moving average
method. - Statistics:

Applicant's summary and conclusion
- Interpretation of results:
- toxic
- Remarks:
- Migrated information Oral acute toxicity Cat 4 Criteria used for interpretation of results: EU
- Conclusions:
- Based on these results, the product tested (75 % C12-18-alkylbis(hydroxyethyl)methyl, chloride (CAS no 71808-53-2) and 25% water) is classfied as harmful by oral ingestion as that term is defined in the Regulation (EC) No 1272/2008 of the European Parliament and of the Council of 16 December 2008.
Based on the concentration of the product, the same classification is valid for the active ingredient C12-18-alkylbis(hydroxyethyl)methyl, chloride (CAS no 71808-53-2). - Executive summary:
The study was conducted to evaluate the acute oral toxicity of the product (75 % C12 -18 -alkylbis(hydroxyethyl)methyl, chloride and 25% water)
according to US 16CFR 1500. The acute oral LD50 of the product tested was determined to be 1.71 g/kg bw. According to these regulations, the product would be considered harmful if swallowed.
Based on the concentration of the product, the same classification is valid for the active ingredient C12-18-alkylbis(hydroxyethyl)methyl, chloride (CAS no 71808-53-2). The acute oral LD50 of the active ingredient tested was determined to be >300 - 2000 mg/kg bw.
Label requirements under GHS: Symbol "Exclamation mark"; Signal word "Warning"; Hazard statement "Harmful if swallowed"
