Interpretation of results:
GHS criteria not met
Conclusions:
Under the test conditions, oral LD50 of Abies alba oil from needles is higher than 5000 mg/kg bw in rats therefore it must not be classified according to the CLP Regulation (EC) No. 1272/2008 and Globally Harmonized System (GHS).
Executive summary:

In an acute oral toxicity study (limit test), groups of Sherman-Wistar rats (5/sex/dose) were given a single oral dose of Abies alba oil from needles at 5000 mg/kg bw. Animals were then observed for mortality and clinical signs daily for 14 days.

No mortality was observed. Animals were lethargic soon after dose administration and full recovery was observed 24 h later. In this study, the oral LD50 of Abies alba oil from needles was higher than 5000 mg/kg bw in rats.

 

Under the test conditions, oral LD50 of Abies alba oil from needles is higher than 5000 mg/kg bw in rats therefore it must not be classified according to the CLP Regulation (EC) No. 1272/2008 and Globally Harmonized System (GHS).

This study is considered as acceptable and satisfies the requirement for acute oral toxicity endpoint.

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed
Dose descriptor:
LD50
Value:
5 000 mg/kg bw
Quality of whole database:
Only basic data given in the available study. However, no death out of ten animals was observed at the dose level of 5000 mg/kg bw, which is 2.5 times more than the limit dose of the OECD 401/423/425. A repeat study is unlikely to show worse effects, therefore this study was considered sufficiently robust to cover this endpoint.

Acute toxicity: via inhalation route

Endpoint conclusion
Endpoint conclusion:
no study available

Acute toxicity: via dermal route

Endpoint conclusion
Endpoint conclusion:
no study available

Additional information

Acute toxicity: via oral route:

A key study was identified (Shelanski, 1972, Rel. 2). In this limit acute oral toxicity study, 10 rats (5/sex) were administered a single oral dose of test material of 5000 mg/kg bw. The animals were observed for mortality for 14 days.

No mortality was observed at this dose. Animals were lethargic soon after dose administration and full recovery was observed 24 h later.

Oral LD50 of Fir silver (Abies alba) was higher than 5000 mg/kg bw in rats.


Justification for classification or non-classification

Harmonized classification:

Pine needle oil has no harmonized classification according to the Regulation (EC) No. 1272/2008.

Self-classification:

Acute toxicity via Oral route:

Based on the available information, the substance is:

-not classified according to the CLP as the oral LD50 is higher than 2000 mg/kg bw

-not classified according to the GHS since there is no reliable evidence that indicates the LD50 to be in the range of Category 5 values (GHS criteria not met).

Acute toxicity via Dermal route:

This information is not available and not required for this tonnage band.

Acute toxicity via Inhalation:

This information is not available and not required for this tonnage band.

Specific target organ toxicity: single exposure (Oral):

The classification criteria according to the Annex VI of the Regulation (EC) No. 1272/2008 as specific target organ toxicant (STOT) – single exposure, oral are not met since no reversible or irreversible adverse health effects were observed immediately or delayed after exposure and no effects were observed at the guidance value (oral) for a Category 1 classification (C ≤ 300 mg/kg bw) and at the guidance value (oral) for a Category 2 classification (2000 mg/kg bw ≥ C > 300 mg/kg bw). Therefore no classification is required.

The criteria for Transient Organ effects (STOT-SE Category 3) according to the CLP and to the GHS are not met since narcotic effects were not observed in the acute oral toxicity study.

Specific target organ toxicity: single exposure (Dermal):

This information is not available. Not required for substances at the REACH Annex VII tonnage level.

Specific target organ toxicity: single exposure (Inhalation):

This information is not available. Not required for substances at the REACH Annex VII tonnage level.

Aspiration hazard:

According to the Regulation (EC) No. 1272/2008, Substances in Category 1 for aspiration hasard include but are not limited to certain hydrocarbons, turpentine and pine oil. Based on its composition (> 10% of aspiration toxicants, i.e. limonene, pinene), Fir silver oil should be classified for aspiration hazard:

- H304, May be fatal if swallowed and enters airways according to the regulation (EC) No. 1272/2008 and to the GHS.
