Executive summary:

The compound is composed of several identified constituents and in that, it can be considered as a mixture according to the definition of the CLP Regulation.

The decision logic for classification of mixtures from the ECHA Guidance on the Application of the CLP Criteria (2017) was used to determine the skin irritation/corrosion hazard of the registered substance. The decision of classification as skin irritant was based on existing data on constituents (additivity principles): the registered substance has more than 10% of its constituents classified as Skin irritant Category 2 and should be classified as a skin irritant cat.2 without further testing according to the rules for classification of mixtures of Regulation (EC) No 1272/2008.

Conclusions:

Under the test conditions, Abies alba oil from needles induced moderate skin irritation in rabbits.

Executive summary:

In an acute dermal toxicity study (limit test), six rabbits were given a single dermal application of Abies alba oil from needle at 5000 mg/kg bw. Animals were observed for mortality, clinical signs and local reactions for 14 days.

No mortality was observed. Moderate erythema followed by drying and cracking and shedding of skin ( exfoliation).No other clinical signs were observed.

Under the test conditions, Abies alba oil from needle induced moderate skin irritation in rabbits.

This study was conducted according to a non-standard method and adequate scoring of skin effects was not provided, therefore it was not possible to take a decision on the classification based solely on this study.

The mixture is composed of several identified constituents and in that, it can be considered as a mixture according to the definition of the CLP Regulation. The decision logic for classification of mixtures from the ECHA Guidance on the Application of the CLP Criteria (2017) was used to determine the serious eye damage/ eye irritant hazard of the registered substance. The decision of classification as irritant to the eyes was based on existing data on constituents (additivity principles) the registered substance has more than 10% of its constituents classified as Eye irritant Category 2 and should be classified as a Eye irritant Category 2 without further testing according to the rules for classification of mixtures of Regulation (EC) No 1272/2008.

Additional information

The decision logic for classification of mixtures from the ECHA Guidance R.7a (2017) was used to determine the skin irritation/corrosion and eye irritation hazards of Fir silver (Abies alba) oil.

Skin irritation/corrosion:

The decision of classification was based on the following arguments:

1/ Existing animal data: Skin irritation was observed in rabbits in an acute dermal toxicity study (Shelanski, 1972) at the dose of 5000 mg/kg bw. Dermal reactions noted.Adequate scoring of skin effects was not provided, therefore it was not possible to take a decision on the classification based solely on this study. However, based on these data, the test substance is considered as not corrosive to skin.

2/ Existing data on constituents (additivity principles):

- all Fir silver oils having equal or more than 10% of their constituents classified as Skin irritant Category 2 should be classified as skin irritant without further testing according to the Regulation (EC) No 1272/2008.

Eye irritation:

Fir silver oil has not been tested itself, but there are sufficient data on its individual ingredients to adequately characterize the hazard of the mixture. Additivity principles were therefore applied:

- all Fir silver oils having equal or more than 10% of their constituents classified as Eye irritant Category 2 should be classified as eye irritant without further testing according to the Regulation (EC) No 1272/2008.

Justification for classification or non-classification

Harmonized classification:

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

Self-classification:

Based on the typical composition provided by the Lead Registrant, Fir silver oil is classified as skin irritant:

- Skin Irritant Category 2 (H315: Causes skin irritation) according to the criteria of the Regulation (EC) No. 1272/2008 (CLP) and to the GHS.

Based on the typical composition provided by the Lead Registrant, Fir silver oil is also classified as eye irritant:

- Irritating to eyes Category 2 (H319: Causes serious eye irritation) according to the criteria of the Regulation (EC) No. 1272/2008 (CLP) and to the GHS.

No information was available regarding respiratory irritation.
