- Executive summary:
There was limited reporting.
The study was performed with similarities to OECD Guideline 401 (Acute Oral Toxicity), but not according to GLP standards.
The test material was evaluated for its acute oral toxicity potential in albino rats when administered as gavage doses at levels of 31.6, 100, 316, 1000, 3160 and 10000 mg/kg to males. No mortality occured in animals dosed at the 31.6, 100, 316 and 1000 mg/kg level. At dose level 3160 mg/kg 1/5 animal died and all (5/5) animals died at the 10000 mg/kg level. Clinical signs of toxicity included depression, ptosis and depressed righting and placement reflexes. Gross pathologic examination on the animals that died showed congestion of the lungs, kidneys and adrenals, and irritation of the gastrointestinal tract. Gross pathologic examination at termination revealed nothing remarkable.
Conclusion: The acute oral LD50 of the test item for male albino rats is 4470 mg/kg of body weight, with confidence limits from 2820 to 7080 mg/kg.
According to GHS the substance is classified as toxicity category V.

- Remarks:

- Conclusions:
- The single dose acute dermal LD50 of the test item , moistened with 3 ml of distilled water and applied to the skin for 24 hours, is greater than 2000 mg/kg bw. Because higher concentrations than 2000 mg/kg had not been tested and effects at those higher concentrations are unknown the test material was classified in Category 5 according to OECD-GHS.
- Executive summary:
The test item was evaluated for its acute dermal toxicity potential in albino rabbits. The study is comparable to OECD Guideline 402 (Acute Dermal Toxicity). The study was designed and performed according to Good Laboratory Practice Standards.
For 24 hours 2 g/kg of the test substance is applied to the skin of six albino rabbits (test material moistened with 3 ml of distilled water per application). The test sites of three of the six animals were abraded. No mortalities occurred through the study. One rabbit was observed to show signs of toxicity involving difficulty breathing, nasal discharge, nictitating membranes reddened and swollen with marked lacrimation on days 1 through 14. Moderate to severe skin irritation was noted in all rabbits during the study.
Signs of skin irritation observed were slight to moderate erythema, edem and atonia on days 1 through 9, subsiding by day 10 in the majority of rabbits. Sligh desquamation increasing to marked desquamation was noted beginning on days 4 or 5, continuing throughout the study. On days 4 through 7 slight to moderate fissuring was observed. On day 4 of the study all of the rabbits test areas were leathery to touch and eschar formation was then noted on day 5 continuing throughout the study. Exfoliation began on day 6 or 7 in four of the rabbits and days 10 and 13 on two of the rabbits. Observations were up to 14 days.
The single dose acute dermal LD50 of the test item, moistened with 3 ml of distilled water and applied to the skin for 24 hours, is greater than 2000 mg/kg bw.

Additional information
Acute oral toxicity:
Aromatic hydrocarbons, C10-13, reaction products with branched nonene, sulphonated, sodium salts are available with high and low nonene alkylation. These products are representative of what would be considered low and high toxicity ranges and therefore are key studies for the oral acute toxicity assessment.

For two of the high nonene substituted substances the results indicate that no classification is needed for CLP, but the high nonene product which contains 14% docusate, shows higher toxicity. The acute oral toxicity of docusate is 4620 mg/kg (IUCLID from ECB). On the other hand docusate is known to increase absorption and toxicity of other substances following oral intake.
For the low nonene substitution, the results from the low nonene product containing 35% LAS show the highest toxicity, and looks like an outlier compared to the other results. However, this could largely be explained with the presence of 35% LAS, which has on its own a LD50 between 1000 and 2000 mg/kg.
Overall, reports on the products with high and low nonene substituted show comparable, relatively low acute toxicity. For purpose of classification, these studies point at an LD50 in range 2000-5000 for the pure substance. No further studies seem necessary.
Acute dermal toxicity:
Results from the key study indicate low systemic toxicity following administration via dermal route. Application to the skin of 2 g/kg bw for 24 hours resulted to desquamation, fissuring, eschar formation and exfoliation. No mortality occurred. Only one animal showed signs of toxicity involving difficulty breathing, nasal discharge and nictitating membranes reddened and swollen with marked lacrimation.
(LD50 > 2000 mg/kg). Although this substance contains about 35% LAS, it can in view of the higher oral toxicity (see above) of such mixture considered to represent a worst case result already. Consequently, no further studies would be required. No classification for acute dermal toxicity is indicated.
Acute inhalation toxicity:
No data following testing via inhalation is available. REACH stipulates that testing by the inhalation route is appropriate if exposure of humans via inhalation is likely, taking into account the vapour pressure of the substance and/or the possibility of exposure to aerosols, particles or droplets of an inhalable size. No acute inhalation data is available on the substance; however it has a low vapour pressure of 0.0015 Pa at 20°C and the use of the substance is not expected to generate respirable aerosols. The substance shows (severe) irritating effects on skin (especially following repeated exposures) and classified for eye damage cat.1. In view of the low systemic toxicity following oral exposures, it can be expected that exposures via inhalation will be characterised by local effects. Testing for acute systemic toxicity via inhalation is therefore not indicated.
Justification for classification or non-classification
For purpose of classification, the available acute toxicity data following oral dosing all point at a LD50 in range 2000-5000. They also indicate that there is no difference between low or high nonene substitution. The substance therefore needs to be classified for acute toxicity according to GHS as Cat.5, but classification for CLP is not required.
Available data for acute dermal toxicity also show low systemic toxicity. The test indicates that local irritating effects are seen before any systemic effects occur. To this can be remarked that based on the physic-chemical properties of the substance, dermal absorption is likely to be lower than oral absorption. Further acute dermal testing is not justified with severely irritating materials, or even corrosive upon longer exposures. No classification is needed for acute dermal toxicity.
For acute inhalation toxicity the information for classification is lacking, and testing is not justified. REACH stipulates that testing by the inhalation route is appropriate if exposure of humans via inhalation is likely, taking into account the vapour pressure of the substance and/or the possibility of exposure to aerosols, particles or droplets of an inhalable size. No acute inhalation data is available on the substance; however it has a low vapour pressure of 0.0015 Pa at 20°C and the use of the substance is not expected to generate respirable aerosols. Based on the available data low systemic toxicity can also be expected via inhalation route.
Based on its physical appearance as solid there is no need for classification for aspiration hazard.
