Six rabbits (weighing 2.5 to 3.4 kg) were prepared by clipping their trunks free from hair. Two areas on the back of each rabbit were selected: one area of skin was abraded; the remaining area was left intact. 0.5 ml of the test material, Lime oil, was applied to each area. The areas of application were immediately covered with two single layers of gauze approximately one-inch square. The gauze was secured in place with adhesive tape, and the entire trunk wrapped with a nonabsorbent binder. The binder was removed after 24 hours, and the effects (erythema and edema) scored by the Draize method. Scoring was repeated at 72 hours.

Executive summary:

A primary skin irritation study was carried out to define irritational responses to Lime oil. No guideline has been followed. Six rabbits (weighing 2.5 to 3.4 kg) were prepared by clipping their trunks free from hair. Two areas on the back of each rabbit were selected: one area of skin was abraded; the remaining area was left intact. 0.5 ml of the test material, Lime oil, was applied to each area. The areas of application were immediately covered with two single layers of gauze approximately one-inch square. The gauze was secured in place with adhesive tape, and the entire trunk wrapped with a nonabsorbent binder. The binder was removed after 24 hours, and the effects (erythema and edema) scored by the Draize method. Scoring was repeated at 72 hours. The individual Primary Irritation Index score obtained at 24 and 72 hours was 1.0. Erythema score was 4.0 and edema score was 0. Lime oil appeared to be mildly irritating to rabbit skin. As the report is very concise, the documentation is insufficient for an assessment, and interpretation of results remain inconclusive.

Principles of method if other than guideline:
An Acute Dermal Toxicity Limit test was performed as a standard acute method. Six male/female rabbits were prepared by clipping their trunks free from hair. Two areas on the back of each rabbit were selected: one area of skin was abraded; the remaining area was left intact. A dose of 5 ml/kg of liquid Lemon oil was applied to the skin of each of a group of rabbits. Liquid test material was delivered under a rubber sleeve by using a hypodermic syringe; then the sleeve was covered with Webril padding. The rabbits were fitted with a collar to prevent the removal of the wrappings. 24 hours later, the binders were removed, and the local dermal reactions were scored according to the method of Draize. Toxic effects, dermal reactions, and mortality were recorded daily for 14 days. A necropsy was performed on animals that died during the course of the study and on those animals which were killed (by air embolism) at termination.

Classification of skin irritation is based on acute dermal toxicity test. No tissue damage observed at termination.

Interpretation of results:
irritating
Remarks:
Criteria used for interpretation of results: expert judgment
Conclusions:
An Acute Dermal Toxicity Limit test was performed as a standard acute method. As no detailed scoring data is available, it is not possible to classify lemon oil according to the EU classification criteria outlined in the CLP Regulation (1272/2008/EC). However, the available scores at 24 hrs indicate lemon oil should be considered irritating to the skin.
Executive summary:

Skin irritation potential of lemon oil was determined in an acute dermal toxicity limit test, which was performed as a standard acute method. Six male/female rabbits were prepared by clipping their trunks free from hair. Two areas on the back of each rabbit were selected: one area of skin was abraded; the remaining area was left intact. A dose of 5 ml/kg of liquid Lemon oil was applied to the skin of each of a group of rabbits. The test material was delivered under a rubber sleeve by using a hypodermic syringe; then the sleeve was covered with Webril padding. The rabbits were fitted with a collar to prevent the removal of the wrappings. The binders were removed 24 hours later, and the local dermal reactions were scored according to the method of Draize. Toxic effects, dermal reactions, and mortality were recorded daily for 14 days. A necropsy was performed on animals that died during the course of the study and on those animals which were killed (by air embolism) at termination.

Observed skin irritation was as follows: erythema score: between 2-4 in all animals; edema score: between 1-3 in 4 animals; Discoloration: noted in 1 animal; Scaling: noted in 5 animals; Eschar formation: noted in 5 animals. 1 out of 6 animals died during study. As no detailed scoring data is available, it is not possible to classify lemon oil according to the EU classification criteria outlined in 67/548/EEC and 1272/2008. However, the available scores at 24 hrs indicate lemon oil should be considered irritating to the skin.

24 hours after the test product application, a slight to moderate erythema associated with a moderate oedema was noted on the treated area. The oedematous reaction was totally reversible the 6th day of the test and the erythematous reaction between the 8th and the 11th day of the test.
Other effects:
The body weight of the animals was within the range commonly recorded for this strain.

The authors conclude that according to the classification established in the Journal Officiel de la Republique Francaise, dated February 21st, 1982, the results obtained, in these experimental conditions, enabled to conclude that the test product, COLD PRESSED ORANGE OIL, according to the scales of interpretation retained, is irritant to skin (Primary Skin Irritation (Psi) = 3.5).

Interpretation of results:
other: not irritating
Remarks:
CLP criteria not met
Conclusions:
Some erythema and oedema was observed in a skin irritation study according to OECD404, however according to EU criteria outlined in 1272/2008 (GHS/CLP), the substance does not have to be classified as irritating.
Executive summary:

A skin irritation study was conducted according to OECD guideline 404, 1992, using the test material Cold Pressed Orange Oil on the intact skin of 3 male albino rabbits. Each test site was treated with 0.5 ml of the undiluted test material and was semioccluded for 4 hours. Observations for dermal irritation were made at 1 hour, and then 24, 48 and 72 hours after removal of the patch, and thereafter daily for 12 days. The scoring system was in compliance with OECD 404. The skin reactions (Erythema and Eschar formation/Edema formation) were appreciated 1 hour and then 24, 48 and 72 hours after removal of the patch.

The mean Erythea/Eschar scores, calculated from the numerical values given to the skin irritation of each animal observed at the 24, 48, and 72 hour were 2.0, 1.7, and 2.0. The mean Oedema scores were 2.0, 1.3, and 1.3. Based on these results and according to EU criteria,outlined in 1272/2008 (GHS/CLP), the substance does not have to be classified as irritating.

The justification for read across is provided in the attached background material of the chapter summary.
Justification for type of information:
Three in vivo skin irritation studies with 3 different NCSs showed that these could be considered irritating, while the study with orange oil did not result in skin irritation. D-Limonene is also known to be irritating. As D-limonene is present in all NCSs of this group at levels higher than the 20% threshold mentioned in the classification and labelling directive (1999/45/EC, DPD and 1272/2008/EC, CLP and as three studies showed evidence of skin irritation, these results are read across to the other NCSs and the whole group is considered irritating to the skin and classified as R38 or H315.

Executive summary:

A primary skin irritation study was carried out to define irritational responses to Lime oil. No guideline has been followed. Six rabbits (weighing 2.5 to 3.4 kg) were prepared by clipping their trunks free from hair. Two areas on the back of each rabbit were selected: one area of skin was abraded; the remaining area was left intact. 0.5 ml of the test material, Lime oil, was applied to each area. The areas of application were immediately covered with two single layers of gauze approximately one-inch square. The gauze was secured in place with adhesive tape, and the entire trunk wrapped with a nonabsorbent binder. The binder was removed after 24 hours, and the effects (erythema and edema) scored by the Draize method. Scoring was repeated at 72 hours. The individual Primary Irritation Index score obtained at 24 and 72 hours was 1.0. Erythema score was 4.0 and edema score was 0. Lime oil appeared to be mildly irritating to rabbit skin. As the report is very concise, the documentation is insufficient for an assessment, and interpretation of results remain inconclusive.

As D-limonene is present in all NCSs of this group at levels higher than the 20% threshold mentioned in the classification and labelling directive (1999/45/EC, DPD and 1272/2008/EC, CLP and as three studies showed evidence of skin irritation, these results are read across to the other NCSs and the whole group is considered irritating to the skin and classified as R38 or H315.

Interpretation of results:
irritating
Remarks:
Criteria used for interpretation of results: expert judgment
Conclusions:
An Acute Dermal Toxicity Limit test was performed as a standard acute method. As no detailed scoring data is available, it is not possible to classify lemon oil according to the EU classification criteria outlined in the CLP Regulation (1272/2008/EC). However, the available scores at 24 hrs indicate lemon oil should be considered irritating to the skin.
Executive summary:

Skin irritation potential of lemon oil was determined in an acute dermal toxicity limit test, which was performed as a standard acute method. Six male/female rabbits were prepared by clipping their trunks free from hair. Two areas on the back of each rabbit were selected: one area of skin was abraded; the remaining area was left intact. A dose of 5 ml/kg of liquid Lemon oil was applied to the skin of each of a group of rabbits. The test material was delivered under a rubber sleeve by using a hypodermic syringe; then the sleeve was covered with Webril padding. The rabbits were fitted with a collar to prevent the removal of the wrappings. The binders were removed 24 hours later, and the local dermal reactions were scored according to the method of Draize. Toxic effects, dermal reactions, and mortality were recorded daily for 14 days. A necropsy was performed on animals that died during the course of the study and on those animals which were killed (by air embolism) at termination.

Observed skin irritation was as follows: erythema score: between 2-4 in all animals; edema score: between 1-3 in 4 animals; Discoloration: noted in 1 animal; Scaling: noted in 5 animals; Eschar formation: noted in 5 animals. 1 out of 6 animals died during study. As no detailed scoring data is available, it is not possible to classify lemon oil according to the EU classification criteria outlined in 67/548/EEC and 1272/2008. However, the available scores at 24 hrs indicate lemon oil should be considered irritating to the skin.

Other effects:
The body weight of the animals was within the range commonly recorded for this strain.

The authors conclude that according to the classification established in the Journal Officiel de la République Française, dated July 10th, 1992, the results obtained, in these experimental conditions, enabled to conclude that the test product, Cold Pressed Orange Oil, according to the scales of interpretation retained, is slightly irritant for the eye (Maximum Ocular Irritation Index (Max. O.I.=14.0).

Interpretation of results:
not irritating
Remarks:
Criteria used for interpretation of results: EU
Conclusions:
In an eye irritation study performed according to OECD405, orange oil did not induce significant or irreversible damage to the rabbit eye. Based on these results and according to the EU criteria outlined in Annex I of 1272/2008/EC (CLP/EU-GHS), Cold Pressed Orange Oil does not have to be classified and has no obligatory labelling requirement with respect to eye irritation in rabbits.
Executive summary:

The primary eye irritation potential of Cold Pressed Orange Oil was investigated according to OECD test guideline no. 405, 1987. The test item was applied by instillation of 0.1 ml into one eye of each of 3 male New Zealand White rabbits.

The ocular reactions observed during the study remained slight to moderate and only recorded at the conjunctivae level. The mean score was calculated across the 3 scoring times for each animal for corneal opacity, iris lesion, redness and chemosis of the conjunctivae, separately, and was 0.0 for all three animals for corneal opacity and iris lesions, and 1.0 for reddening of the conjunctivae for all three animals. It is concluded that orange oil did not induce significant or irreversible damage to the rabbit eye. Based on these results and according to the EU criteria outlined in Annex I of 1272/2008/EC (CLP/EU-GHS), Cold Pressed Orange Oil does not have to be classified and has no obligatory labelling requirement with respect to eye irritation in rabbits

Additional information

Skin irritation

Three in vivo skin irritation studies with grapefruit, lemon and lime oil showed that these NCSs should be considered irritating, although these studies were not conducted according to the guideline (only one time point was included). The study with orange oil should be classified as skin irritating according to the French DSD classification system, but according to CLP Orange oil in this study would be classified as not skin irritating.

 

D-limonen, which is the major constituent, is also known to be irritating to the skin and classified with R38. As D-limonene is present in all NCSs at levels higher than the thresholds mentioned for classification and labeling (in both 68/548/EEC and 1272/2008/ECand three studies showed evidence of skin irritation, these results were read across to the other NCSs: The whole citrus NCS group is considered to be irritating to the skin.

 

Eye irritation

Two in vivo eye irritation studies with orange and lemon oil showed that these NCSs are not irritating to the eye. A study with D-limonene showed that this major constituent also was not irritating to the eye. These results are read across to the other citrus NCSs and the whole group is considered non-irritating to the eye.This read across is considered valid because of:1) the similar origin of the oils in this group, 2) the dominant presence of D-limonene in all oils of this group, 3) the same and similar other constituents.

Justification for classification or non-classification

Based on the available information, the substance tangerine oil needs to be classified for skin irritation according to the criteria outlined in Annex VI of 67/548/EEC and Annex I of 1272/2008/EC (CLP/EU-GHS).

Based on the available information, the substance tangerine oil does not need to be classified as eye irritant according to the criteria outlined in Annex VI of 67/548/EEC and Annex I of 1272/2008/EC (CLP/EU-GHS).
