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.

- Results from the two test method endpoints, opacity and permeability, were combined in an empirically derived formula to generate an in vitro irritancy score.
- The following formula was used to determine the in vitro irritancy score:
In Vitro Irritancy Score = mean opacity value + (15 x mean OD492 value)
Additionally, the opacity and permeability values were evaluated independently to determine whether the test item induced a response through only one of the two endpoints. - Irritation parameter:

The corneas treated with the negative control item were clear post treatment and post incubation. The corneas treated with the positive control item were cloudy post treatment and post incubation.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the test conditions, Camphor white oil is considered not to be an ocular corrosive or severe irritant. No definitive conclusion can be established since the IVIS was > 3 and ≤ 55 (test item is not predicted as causing serious eye damage and not classified for eye irritation or serious eye damage).
- Executive summary:
In an in vitro eye irritation study conducted according to the OECD Guideline 437 and in compliance with GLP, 3 bovine corneas were applied with 0.75 mL of undiluted Camphor white oil for 10 minutes at 32 ±1 ºC followed by an incubation period of 120 ± 10 minutes at 32 ±1 ºC. Negative and positive control items were tested concurrently. After incubation the BCOP holders were removed from the incubator and a final opacity reading was taken. Each cornea was visually observed. The two endpoints, decreased light transmission through the cornea (opacity) and increased passage of sodium fluorescein dye through the cornea (permeability) were combined in an empirically derived formula to generate an in vitro irritancy score.
The corneas treated with the test item were clear post treatment and post incubation. The corneas treated with the negative control item were clear post treatment and post incubation. The corneas treated with the positive control item were cloudy post treatment and post incubation. The in vitro irritancy score for negative and positive controls were 1.4 and 38.7, respectively and the values were within the respective ranges and therefore the study was considered valid. The in vitro irritancy score for the test item was 3.4, which is considered not to be an ocular corrosive or severe irritant.
Under the test conditions, Camphor white oil is considered not to be an ocular corrosive or severe irritant. No definitive conclusion can be established since the IVIS was > 3 and ≤ 55 (test item is not predicted as causing serious eye damage and not classified for eye irritation or serious eye damage).
This study is considered as acceptable and satisfies the requirement for eye irritation endpoint.

Additional information
The test material is composed of several identified constituents and in that, it can be considered as a mixture according to the definition of the CLP Regulation.
Skin irritation/corrosion:
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 Camphor white oil. The decision of classification as skin irritant was based on the following arguments:
1/ Existing data on constituents (additivity principles): The registered substance has more than 10% of its constituents classified as Skin irritant Category 2 and more than 10% classified as Eye irritant Category 2 and should be classified as a skin irritant and eye irritant without further testingaccording to the rules for classification of mixtures of Regulation (EC) No 1272/2008.
2/ Existing supporting animal data: a supporting acute dermal toxicity study revealed that severe edema and extensive necrosis of the rabbit skin resulted from treatment with Camphor at a single dose of 5 mL/kg bw. Therefore a primary skin irritation study was carried out to further define irritational response to this test material. Skin irritation was observed in this rabbit skin irritation study performed similarly to US-FHSA guideline (Wong, 1971).
Eye irritation:
1/ A supporting study was identified (Warren, 2014, Rel.1). In this BCOP assay conducted according to the OECD Guideline 437 and in compliance with GLP, the in vitro irritancy score for the test item was 3.4.
Camphor white oil is not an ocular corrosive or severe irritant. However, based on this study, no definitive conclusion on eye irritation can be established since the IVIS was > 3 and ≤ 55 (test item is not predicted as causing serious eye damage and not classified for eye irritation or serious eye damage).
2/ Additivity principles were therefore applied to conclude on classification: all Camphor white oil oils having 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:
Camphor white 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, Camphor white oil is classified as Skin Irritant Category 2 (H315: Causes skin irritation) according to the criteria of the Regulation (EC) No.1272/2008 (CLP) and the GHS.
Based on the typical composition provided by the Lead Registrant, Camphor white oil is also classified as Eye irritant Category 2 (H319: Causes serious eye irritation) according to the criteria of the Regulation (EC) No. 1272/2008 (CLP) and the GHS.
No information was available regarding respiratory irritation.
