Alcohols, C18-22, reaction products with maleic anhydride and sodium bisulfite

Endpoint summary

Description of key information

Several studies for oral and dermal acute toxicity were performed on related substances, demonstrating LD50 >2000 mg/kg bw for both routes. Inhalation toxicity testing was waived based upon the fact that acute inhalation exposure as such is very unlikely due to the physchem properties of the substance and the handling during production and use

MAXIMUM DOSE VOLUME APPLIED: 4.22 mL/kg bw

DOSAGE PREPARATION (if unusual):
Butanedioic acid, 2(or 3)-sulfo-, 4-[2-[(1- oxo(C12-C18(even numbered) and C18unsaturated)alkyl))amino]ethyl]esters, disodium salts was used as supplied. The administration volume was 4.22 mL/kg bw for a dose of 2000 mg/kg bw as the density of the test item was 1.14 g/mL and a correction factor of 2.41 was employed in order to correct for a content of the solid material of 41.5% only.
The pH value of the supplied test item was 6.4.


CLASS METHOD (if applicable)
- Rationale for the selection of the starting dose: The dose used is selected from a series of defined dose levels. Due to the small number of animals used with this method, there is no need to perform a range finding test.

Doses:

1 dose group (Limit test): 2000 mg/kg bw (dose level refers to the solids ingredients of the test item)

No. of animals per sex per dose:

6

Control animals:

no

Details on study design:

- Duration of observation period following administration: 14 days
- Frequency of observations and weighing: Observations were performed before and immediately, 5, 15, 30 and 60 min, as well as 3, 6 and 24 hours after administration. All surviving animals were observed for a period of 14 days. Individual body weights were recorded before administration of the test item and thereafter in weekly intervals up to the end of the study. Changes in weight were calculated and recorded.
- Necropsy of survivors performed: yes
- Other examinations performed: clinical signs (changes of skin and fur, eyes and mucous membranes, respiratory and the circulatory, autonomic and central nervous system and somatomotor activity as well as behaviour pattern; tremors, convulsions, salivation, diarrhoea, lethargy, sleep and coma), body weight, gross pathology

Conclusions:

According to the EC-Commission directive 67/548/EEC and its subsequent amendments on the approximation of the laws, regulations and administrative provision relating to the classification, packaging and labelling of dangerous substances and the results obtained under the present test conditions,Butanedioic acid, 2(or 3)-sulfo-, 4-[2-[(1- oxo(C12-C18(even numbered) and C18unsaturated)alkyl))amino]ethyl]esters, disodium salts requires no classification (as LD50 > 2000 mg/kg).
Also, according to the EC Regulation 1272/2008 and subsequent regulations, the test material is not classified for acute oral toxicity.

Executive summary:

In this experiment Butanedioic acid, 2(or 3)-sulfo-, 4-[2-[(1- oxo(C12-C18(even numbered) and C18unsaturated)alkyl))amino]ethyl]esters, disodium salts was examined for acute toxicity after a single oral administration to 6 femaleCD/Crl:CD(SD)rats. The test substance dosed by oral gavage at 2000 mg active ingredient/kg bw did not reveal any signs of toxicity. No death was recorded within the 14 days observation period. All animals gained the expected weight throughout the whole study period. No pathological changes were observed at necropsy.The LD₅₀value was ranked exceeding 2000 mg/kg bw.

Additional information

No test data were available for current substance, however read across data were available from:

a) Butanedioic acid, 2(or 3)-sulfo-, 4-[2-[(1-oxo(C12-C18 (even numbered) and C18 unsaturated)alkyl))amino]ethyl]esters, disodium salts

b) Reaction product of (R)-12-hydroxy-N-(2-hydroxyethyl)oleamide and maleic anhydride and sodium hydrogensulfite.

c) Lanoline alcohol sulphosuccinated sodium salt.

d) Alkenes hydroformylated, sulfosuccinates, sodium salt

All results are consistent and the results can be applied also to the registered substance

Justification for selection of acute toxicity – oral endpoint
All studies are perfomed on similar substances, all composed by the same sulphosuccinic part and differrent chainlenghts: chainlenght can vary from very high molecular weight (like in hydroformilation products and lanoline) to relatively low like in the dioctyl drivative. They contribute and agree to the same result. The substance is not toxic for acute oral exposure

Justification for selection of acute toxicity – dermal endpoint
All studies are perfomed on similar substances, all composed by the same sulphosuccinic part and differrent chainlenghts: chainlenght can vary from very high molecular weight (like in hydroformilation products and lanoline) to relatively low like in the dioctyl drivative. They contribute and agree to the same result. The substance is not toxic for acute dermal exposure

Justification for classification or non-classification

Oral acute toxicity

The substance is not classified for oral toxicity because it doesn't meet the classification criteria of the CLP regulation n. 1272/2008:

Oral (mg/kg bodyweight)

Category 1: ATE ≤ 5

Category 2: 5 < ATE≤ 50

Category 3: 50 < ATE≤ 300

Category 4: 300 < ATE≤ 2 000

Different Sufosuccinates were tested, showing acute oral toxicity values >= 2.000 mg/Kg (range 2.000 - 3540 mg/Kg)

Inhalation acute toxicity

According to the Annex VIII of the REACH Regulation n. 1907/2006, inhalation route is not considered appropriate, based also on vapour pressure and the test can be waived.

Dermal acute toxicity

The substance is not classified for dermal toxicity because it doesn't meet the classification criteria of the CLP regulation n. 1272/2008:

Dermal (mg/kg bodyweight)

Category 1: ATE ≤ 50

Category 2: 50 < ATE≤ 200

Category 3: 200 < ATE≤ 1000

Category 4: 1000 < ATE≤ 2000

The value selected is > 2.000 mg/Kg.
