Safety goggles (acc. to EN 166) or face shields which are product-resistant.

Respiratory

Mask (or half-face respirator) with a filter for organic gases/vapours (acc. to EN 14387, type A).

Skin/Body

Body protection must be chosen depending on activity and possible exposure, e.g. apron, protecting boots, chemical-protection suit (according to EN 14605).

Environmental

Prevent product entry to sewage systems, surface water and/or ground water. In case of incidental entry, inform relevant authorities. All waste materials, e.g. coming from product leaks, or product spills which have been absorbed in a sorption material, should be classified as hazardous waste and they should be transferred to an authorised waste collecting company for disposal. Because of high biodegradability, the liquid product may be discharged directly to the sewage treatment plant.

Ecological Information

Environmental toxicity, biodegradation, and bioaccumulation data

12.1.1. Aquatic toxicity

LC50/96h | Fish: Leuciscus idus melanotus; | 17.1 | mg/l | EC50/48h | Crustacea: Daphnia magna | 39 | mg/l | EC50 /72h A | Algae: Scenedesmus subspicatus. | 16.6 | mg/l; growth rate for freshwater algae | EC120/LC10 or NOEC | (for freshwater algae) | 5.3 | mg/l

12.1 Toxicity

12.1.1.2. LONG-TERM TOXICITY: According to REACH Annex IX, 9.1, Column 2, the test is not required (CSR does not indicate the need for further investigations). 12.1.2. Sediment toxicity: The substance is readily biodegradable, the adsorption potential is low (Log Koc = 2.12), as is the bioconcentration factor (the estimated Log BCF was 1.58). Thus, the substance will be quickly degraded in the environment and partitioning to the sediment will be negligible. Moreover, as bioaccumulation potential is also very low, particular exposure of sediment organisms is highly unlikely. Therefore, no testing is required in accordance with REACH; ANNEX X; No. 9.5.1, column 2. 12.1.3. Terrestrial toxicity: 12.1.3.1. TOXICITY TO SOIL MICRO-ORGANISMS. The substance is readily biodegradable, the adsorption potential is low (low Pow and Koc) and the substance is not very toxic to aquatic organisms. Under these circumstances further experimental data in regard to terrestrial toxicity may be waived according to Column 2 of Annex IX and X, 9.4 of REGULATION (EC) No 1907/2006 together with REACH guidance document R.7C. As the CSA (including EPM results) does not indicate the need for further testing, no new studies on terrestrial toxicity were performed. 12.1.3.2. TOXICITY TO SOIL MACRO-ORGANISMS: Arthropods: The substance is readily biodegradable, the adsorption potential is low (low Pow and Koc) and the substance is not very toxic to aquatic organisms. Under these circumstances further experimental data in regard to terrestrial toxicity may be waived according to Column 2 of Annex IX and X, 9.4 of REGULATION (EC) No 1907/2006 together with REACH guidance document R.7C. As the CSA (including EPM results) does not indicate the need for further testing, no new studies on terrestrial toxicity were performed. Other: The substance is readily biodegradable, the adsorption potential is low (low Pow and Koc) and the substance is not very toxic to aquatic organisms. Under these circumstances further experimental data in regard to terrestrial toxicity may be waived according to Column 2 of Annex IX and X, 9.4 of REGULATION (EC) No 1907/2006 together with REACH guidance document R.7C. As the CSA (including EPM results) does not indicate the need for further testing, no new studies on terrestrial toxicity were performed. 12.1.3.3. TOXICITY TO TERRESTRIAL PLANTS: The substance is readily biodegradable, the adsorption potential is low (low Pow and Koc) and the substance is not very toxic to aquatic organisms. Under these circumstances further experimental data in regard to terrestrial toxicity may be waived according to Column 2 of Annex IX and X, 9.4 of REGULATION (EC) No 1907/2006 together with REACH guidance document R.7C. As the CSA (including EPM results) does not indicate the need for further testing, no new studies on terrestrial toxicity were performed. 12.1.3.4. TOXICITY TO TERRESTRIAL ANIMALS: Birds: The substance is readily biodegradable, the adsorption potential is low (low Pow and Koc), as is the bioconcentration factor (the estimated Log BCF was 1.58). Secondary poisoning is therefore highly unlikely. Because of this, mammalian toxicity data were used to derive PNECoral (as recommended in column 2 of REACH Annex X, No. 9.6.1) and for reasons of animal welfare no new tests on toxicity to birds were performed. Mammals: No relevant information available. 12.1.4. Microbiological activity in sewage treatment systems

Testing for long-term aquatic, sediment, and terrestrial toxicity was waived based on the substance's ready biodegradability, low adsorption potential, and low bioaccumulation potential, as supported by REACH Annex IX and X.

12.2 Persistence and degradability

The substance is readily biodegradable.

The substance is readily biodegradable.

12.3 Bioaccumulative potential

the bioconcentration factor (the estimated Log BCF was 1.58).

12.4 Mobility in soil

the adsorption potential is low (Log Koc = 2.12)

12.1.4. Microbiological activity in sewage treatment systems

12.1.4. Microbiological activity in sewage treatment systems NOEC/24h (activated sludge, domestic) >300 mg/l The substance is readily biodegradable and the initially tested test item concentration is more than 500 times higher than the concentrations that may be expected in the influent of a sewage treatment plant, based on PEC STP values obtained under Chapter 9 for each exposure scenario. Therefore, no testing is required in accordance with REACH; ANNEX VIII; No. 9.1.4, column 2.

12.2. Persistence and degradability

12.2.1. Stability 12.2.1.1. HYDROLYSIS: In accordance with Annex VIII, No. 9.2.2.1, column 2, no testing is required because the substance is readily biodegradable 12.2.1.2. PHOTOTRANSFORMATION IN AIR In this study, rate coefficients at room temperature for the reactions of 2-ethyl-1-hexanol with OH and NO3 radicals and with Cl atoms were determined. These clearly indicate that reaction with OH is the most relevant degradation process for this compound in the atmosphere. In this case a rate constant of 1.13 x 10^-11 cm^-3 / (molecule x s) and an atmospheric lifetime of 24.6 h was determined. The determined rate coefficients are consistent with the expected reactivity given the chemical structure of this compound. 12.2.2. Biodegradation 12.2.2.1. BIODEGRADATION IN WATER Biodegradation in water: readily biodegradable 2-ethylhexanol was readily biodegradable in a MITI-I Test, (equivalent to OECD TG 301-C, reliability category 1). This is in line with the observation that the chemical oxygen demand (COD) was reduced by >95% in the Zahn-Wellens test (OECD 302B guideline; reliability 2) within 5 days demonstrating rapid biodegradation. Day | 1 | 2 | 5 | 7 | 9 % degraded | 23 | 36 | 96 | 97 | 96

12.2 Persistence and degradability

12.2.2.2. BIODEGRADATION IN SOIL The substance is readily biodegradable. Therefore, no testing is required in accordance with REACH; ANNEX IX; No. 9.2.1.3, column 2.

The substance is readily biodegradable, and no soil biodegradation testing is required under REACH Annex IX.

12.3. Bioaccumulative potential

According to "column 2" of Annex IX, no experimental study on bioconcentration in fish needs to be conducted if the substance has a low potential for bioaccumulation. The log Kow of 2.9 for 2-Ethylhexanol (Perstorp, 2010) indicates a low potential for bioaccumulation. In addition the substance is readily biodegradable (NITE, 2002). Therefore and for reasons of animal welfare a fish study is not performed. BCF was calculated using US EPA EPI SuiteTM 4.11 module BCFBAF v. 3.01.

The substance has a low potential for bioaccumulation based on a log Kow of 2.9 and its ready biodegradability. Experimental fish studies were not performed for animal welfare reasons.

12.3. Bioaccumulative potential

Log Kow 2.9 Log Koc 2.12 BCF 38.06 wet weight Log BCF 1.58

12.4. Mobility in soil

12.4.1. Adsorption/desorption Using an accepted calculation program (US EPA EPI SuiteTM 4.11 module KOCWIN v. 2.00) the estimated Koc was 35.28 L/kg according to the structure based MCI-method and 131.1 L/kg according to the method based on log Kow (user entry of experimentally determined value of 2.9 at 25°C). Both values demonstrate a low adsorption potential for the submission substance. Koc 131.1 l/kg (at 20°C)

12.5. Results of PBT and vPvB assessment

Based on the available data it is concluded that 2-ethylhexanol - is readily biodegradable and does not fulfill the P or vP criterion - is not bioaccumulative and does not fulfill the B or vB criterion - does not fulfill the T criterion and therefore is evaluated to be not a PBT or vPvB substance.

2-ethylhexanol is evaluated to be not a PBT or vPvB substance.

12.6. Other adverse effects

No data.
