Description of key information
Acute toxicity: oral
LD50 is greater than 2000 mg/kg body weight after single oral administration to Wistar rats.
Acute toxicity: dermal
The substance, CAS 68130-51-8; EC 268-594-6, is analogous to the substances to be read across to, in terms of basic form, and the degree of substitution of functional groups is not considered to effect the proposed read across for the endpoint of acute dermal toxicity. The substance is not considered to be acutely toxic via the dermal route on the basis of read across.
Key value for chemical safety assessment
Acute toxicity: via oral route

Source: Dobrá Voda, Slovak Republic
Number and Sex of Animals: 6 females
Age at First Dose: 8-12 weeks; female animals were non-pregnant and nulliparous
Animal Health: Health condition of animals was examined by a veterinarian before initiation of the study.
Acclimation: The animals were acclimated under the conditions identical to the conditions during the experiment 5 days prior to the start of treatment. The acclimation was according to the standard operation procedure.
Housing Condition: The animals were housed in plastic cages suspended on stainless steel racks, up to 3 animals per cage in a room equipped with central airconditioning. The average room temperature was maintained within the range of 23.4 ± 0.2° C, relative humidity within 54.4 ± 1.9 %. The light regimen was set to a 12-hour light /12-hour dark cycle. Sanitation was performed according to the standard operation procedures.
Diet: The laboratory food ssniff (Spezialdiäten GmbH, Germany) was offered at recommended doses each day approximately at the same time.
Water: The animals received tap water for human consumption. Drinking water was supplied ad libitum.
Bedding: Lignocel S3/4, Lufa - ITL GmbH, Germany
Animals Identification: The animals in the cage were marked by a line (I-III) on the tail with a waterproof marker. Each cage was marked with the study code, ID of animals and date of administration of the test item.
Justification for the Choice of Species: Normally females are used for testing OECD TG 423 because females are typically the more sensitive gender. - Route of administration:
- oral: gavage
- Vehicle:
- olive oil
- Details on oral exposure:
- The required amount of the test item (according to the body weight and dose) was mixed with vehicle (olive oil) shortly before administration.
- Doses:
- The starting dose could be selected from the fixed dose levels of 5, 50, 300, and 2000 mg/kg body weight. Available information indicated that the test item is likely to be non-toxic with regard to acute toxicity. A limit dose of 2000 mg/kg body weight was therefore used as a starting dose.
- No. of animals per sex per dose:
- One group of 3 females was dosed. Test item-related mortality was not observed during 24 hours and therefore in a second step another 3 females were treated at the same dose level.
- Control animals:
- no
- Details on study design:
- Dose Administration
The test item was administered in a single dose by gavage using a metal stomach tube. Animals were fasted prior to dosing (food but not water were withheld over-night). Following a period of fasting, animals were weighed and the test item administered. After test item administration, food was withheld for further 3-4 hours.
Clinical Observation
Animals were observed individually immediately after administration of the test item and 0.5, 1, 2, and 4 hours later. Each animal was inspected daily for the next 14 days.
Observations included: changes in skin, fur, eyes, mucous membranes, respiratory, circulatory, autonomic and central nervous systems, somatomotor activity, and behavioural pattern. Particular attention was given to potential neurologic endpoints such as tremors, convulsions, salivation, diarrhoea, lethargy, sleep and coma.
Body Weight
Individual weights of animals were measured immediately prior to test item administration and weekly thereafter. Weight differences after first and second weeks after administration were calculated and recorded.
Necropsy
All test animals were subjected to gross necropsy and the results were recorded for each animal. - Statistics:
- Not specified
- Key result
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- >= 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- All (6/6 females) animals survived the limit dose of 2000 mg/kg body weight.
- Clinical signs:
- other: During the follow up period, no animals displayed signs of intoxication, change of health, nor any other adverse reactions.
- Gross pathology:
- All animals were necropsied. During necropsy, no macroscopic findings were observed.
- Other findings:
- Not specified
- Interpretation of results:
- Category 5 based on GHS criteria
- Conclusions:
- The LD50 of the test item Hatcol 1570 is greater than 2000 mg/kg body weight after single oral administration to Wistar rats.
Based on Annex 2d Test Procedure with a Starting Dose of 2000 mg/kg body weight of OECD Guideline 423 it can be concluded that the test item Hatcol 1570 is classified in GHS Category 5/Unclassified with a LD50 cut off value equal to or greater than 5000 mg/kg body weight, after single oral administration to Wistar rats. - Executive summary:
The purpose of the study was to evaluate the potential toxic effect of the test item Hatcol 1570 when administered as a single oral dose to Wistar rats.
The procedure according to OECD Guideline 423 Acute Toxic Class (ATC) method was used.
Available information indicated that the test item is likely to be non-toxic; therefore, a limit dose of 2000 mg/kg body weight was used as a starting dose. One group of 3 females was dosed. Test item related mortality was not observed during 24 hours and therefore in a next step 3 females were treated with the same dose. All 6 females survived the limit dose. The limit dose of 2000 mg/kg body weight did not cause death or evident signs of toxicity. The body weights of 5 animals mildly increased during the study. Stagnation of body weight in one animal between the first and second week was observed. During necropsy, no macroscopic findings were observed.
The LD50 of the test item Hatcol 1570 is greater than 2000 mg/kg body weight after single oral administration to Wistar rats.
Based on Annex 2d Test Procedure with a Starting Dose of 2000 mg/kg body weight of OECD Guideline 423 it can be concluded that the test item Hatcol 1570 is classified in GHS Category 5/Unclassified with a LD50 cut off value equal to or greater than 5000 mg/kg body weight, after single oral administration to Wistar rats.

Mortality/Viability: Twice daily
Body weights: Days 1 (pre-administration), 8 and 15.
Clinical signs: At periodic intervals on the day of dosing (Day 1) and once daily thereafter, until Day 15. The symptoms were graded according to fixed scales and the time of onset, degree and duration were recorded.

Additional information
Acute toxicity: oral
The purpose of the study was to evaluate the potential toxic effect of the test item Hatcol 1570 when administered as a single oral dose to Wistar rats.
The procedure according to OECD Guideline 423 Acute Toxic Class (ATC) method was used.
Available information indicated that the test item is likely to be non-toxic; therefore, a limit dose of 2000 mg/kg body weight was used as a starting dose. One group of 3 females was dosed. Test item related mortality was not observed during 24 hours and therefore in a next step 3 females were treated with the same dose. All 6 females survived the limit dose. The limit dose of 2000 mg/kg body weight did not cause death or evident signs of toxicity. The body weights of 5 animals mildly increased during the study. Stagnation of body weight in one animal between the first and second week was observed. During necropsy, no macroscopic findings were observed.
The LD50 of the test item Hatcol 1570 is greater than 2000 mg/kg body weight after single oral administration to Wistar rats.
Acute toxicity: dermal.
The dermal LD50 value of Decanoic acid, mixed esters with heptanoic acid, octanoic acid and trimethylolpropane in Wistar rats was established to exceed 2000 mg/kg body weight.
Justification for classification or non-classification
Based on the above mentioned results, classification according to the CLP Regulation (EC)1272/2008 is not necessary.
A report justifying the read-across approach is included in IUCLID Chapter 13.
