- TREATMENT
Approximately 24 hours before treatment, the dorsal fur was clipped with electric clippers, exposing an area of approximately 150 square centimetres (10x15 cm2). Whenever considered necessary the treated skin areas were re-lipped at least 3 hours before the observations, to facilitate scoring.
A health inspection was performed prior to the commencement of treatment, to ensure that the animals were in a good state of health. Special attention was paid to the skin to be treated, which was intact and free from abnormalities.
Each animal was treated by dermal application of 0.5 ml of the test substance. The test substance was applied to the skin of one flank, using a metalline patch of 2x3 cm. The patch was mounted on Micropore tape, which was wrapped around the abdomen and secured with Coban elastic bandage. Four hours after the application, the dressing was removed and the skin cleaned of residual test substance using water.
OBSERVATIONS
Mortality/Viability: Twice daily.
Toxicity: At least once daily.
Body Weight: Day of treatment (prior to application) and at termination.
Irritation: The skin reactions were assessed at approximately 1, 24, 48 and 72 hours after the removal of the dressings and test substance.
The irritation scores and a description of all other (local) effects were recorded. Adjacent areas of the untreated skin of each animal served as controls.

Number of animals: 3 Males.
Age and body weight: Animals used within the study were at least 6 weeks old and body weights were at least 1.0 kg.
Identification: Earmark.
Conditions: Animals were housed in a controlled environment, in which optimal conditions were considered to be approximately 15 air changes per hour, a temperature of 21.0 ± 3.0°C (actual range: 16.1 - 23.0°C), a relative humidity of 30-70% (actual range: 43 -79%) and 12 hours artificial fluorescent light and 12 hours darkness per day. Cleaning procedures in the room might have caused the temporary fluctuations above the optimal maximum level of 70% for relative humidity. Based on laboratory historical data, these fluctuations were considered not to have affected the study integrity.
Accommodation: Individually in labelled cages with perforated floors (Scan bur, Denmark, dimensions 56x44x37.5 cm). Acclimatisation period was at least 5 days before start of treatment under laboratory conditions.
Diet: Standard laboratory rabbit diet (Charles River Breeding and Maintenance Diet for Rabbits, Altromin, Lage, Germany) approx. 100 g. per day. Certificates of analysis were examined and retained in the NOTOX archives. In addition, pressed hay (BMI, Helmond, the Netherlands) was provided twice a week.

- Details on study design:
- TREATMENT: All available data relevant to the potential dermal irritation/corrosivity of the substance indicated that no severe effects were to be expected. An in-vitro skin irritation test was considered, but no validated test was found available. Therefore, this in-vivo skin irritation study was started by treatment of a single rabbit (sentinel). The two other animals were treated in a similar manner 7 days later, after considering the degree of skin irritation observed in the first animal.
Approximately 24 hours before treatment, the dorsal fur was clipped with electric clippers, exposing an area of approximately 150 square centimetres (10x15 cm2). Whenever considered necessary the treated skin areas were re-clipped at least 3 hours before the observations, to facilitate scoring.
A health inspection was performed prior to the commencement of treatment, to ensure that the animals were in a good state of health. Special attention was paid to the skin to be treated, which was intact and free from abnormalities.
Each animal was treated by dermal application of 0.5 ml of the test substance. The test substance was applied to the skin of one flank, using a metalline patch of 2x3 cm. The patch was mounted on Micropore tape, which was wrapped around the abdomen and secured with Coban elastic bandage. Four hours after the application, the dressing was removed and the skin cleaned of residual test substance using water.
OBSERVATIONS
Mortality/Viability: Twice daily.
Toxicity: At least once daily.
Bodyweight: Day of treatment (prior to application) and at termination.
Irritation: The skin reactions were assessed at approximately 1, 24, 48 and 72 hours after the removal of the dressings and test substance.
The irritation scores and a description of all other (local) effects were recorded. Adjacent areas of the untreated skin of each animal served as controls. - Irritation parameter:

Corrosion: There was no evidence of a corrosive effect on the skin. - Other effects:
- Colouration: No staining of the treated skin by the test substance was observed. Sticky remnants of the test substance were present on the edges of the treated skin area on day 1.
Toxicity/Mortality: No symptoms of systemic toxicity were observed in the animals during the test period and no mortality occurred. - Interpretation of results:
- GHS criteria not met
- Conclusions:
- Based on the results, HATCOL 3331 does not have to be classified and has no obligatory labelling requirement for skin irritation.
- Executive summary:
Primary skin irritation/corrosion study with HATCOL 3331 in the rabbit (4 -hour semi-occlusive application).
The study was carried out based on the guidelines described in: EC Commission Directive 92/69/EEC, B.4, "Acute Toxicity - Skin irritation", OECD No 404, "Acute Dermal Irritation/Corrosion", US EPA, OPPTS 870.2500, Acute Dermal Irritation and JMAFF, Japanese Test Guidelines.
Three rabbits were exposed to 0.5 ml of HATCOL 3331, applied onto clipped skin for 4 hours using a semi-occlusive dressing. Observations were made 1, 24, 48 and 72 hours after exposure.
Exposure to HATCOL 3331 resulted in very slight erythema and/or very slight oedema in the treated skin-areas of the rabbits, which had resolved within 24 hours in two animals and within 48 hours in the other animal.
Sticky remnants of the test substance were present on the edges of the treated skin area on day 1.
Based on the results and according to the EC criteria for classification and labelling requirements for dangerous substances and preparations (Council Directive 67/548/EEC), HATCOL 3331 does not have to be classified and has no obligatory labelling requirement for skin irritation.

Conditions: Animals were housed in a controlled environment. in which optimal conditions were considered to be approximately 15 air changes per hour, a temperature of 21.0 ± 3.0°C (actual range: 16.1-23.0°C), a relative humidity of 30-70% (actual range: 43-79%) and 12 hours artificial fluorescent light and 12 hours darkness per day. Cleaning procedures in the room might have caused the fluctuations above the optimal maximum level of 70% for relative humidity. Based on laboratory historical data these fluctuations were considered not to have affected the study integrity.
Accommodation: Individually In labelled cages with perforated floors (Scanbur, Denmark, dimensions 56x44x37.5 cm). Acclimatisation period was at least 5 days before start of treatment under laboratory conditions.
Diet: Standard laboratory rabbit diet (Charles River Breeding and Maintenance Diet for Rabbits, Altromin, Lage, Germany) approx. 100 g per day. Certificates of analysis were examined and retained in the NOTOX archives. In addition, pressed hay (BMI, Helmond, The Netherlands) was provided twice a week.
Water: Free access to tap-water. Certificates of quarterly analysis were examined and retained in the NOTOX archives. - Type of coverage:
- semiocclusive
- Preparation of test site:
- clipped
- Vehicle:
- unchanged (no vehicle)
- Controls:
- yes, concurrent no treatment
- Amount / concentration applied:
- Each animal was treated by dermal application of 0.5ml of the test substance.
- Duration of treatment / exposure:
- Four hours.
- Observation period:
- 72 hours
- Number of animals:
- 3 males.
- Details on study design:
- TREATMENT: All available data relevant to the potential dermal irritation/corrosivity of the substance indicated that no severe effects were to be expected. An in-vitro skin irritation test was considered, but no validated test was found available. Therefore, this in-vivo skin irritation study was started by treatment of a single rabbit (sentinel). The two other animals were treated in a similar manner 7 days later, after considering the degree of skin irritation observed in the first animal.
Approximately 24 hours before treatment, the dorsal fur was clipped with electric clippers, exposing an area of approximately 150 square centimetres (10x15 cm2). Whenever considered necessary the treated skin areas were re-lipped at least 3 hours before the observations, to facilitate scoring.
A health inspection was performed prior to the commencement of treatment, to ensure that the animals were in a good state of health. Special attention was paid to the skin to be treated, which was intact and free from abnormalities.
Each animal was treated by dermal application of 0.5ml of the test substance. The test substance was applied to the skin of one flank, using a metalline patch of 2x3 cm. The patch was mounted on Micropore tape, which was wrapped around the abdomen and secured with Coban elastic bandage. Four hours after the application, the dressing was removed and the skin cleaned of residual test substance using water.
OBSERVATIONS
Mortality/Viability: Twice daily.
Toxicity: At least once daily.
Bodyweight: Day of treatment (prior to application) and at termination.
Irritation: The skin reactions were assessed at approximately 1, 24, 48 and 72 hours after the removal of the dressings and test substance.
The irritation scores and a description of all other (local) effect were recorded. Adjacent areas of the untreated skin of each animal served as controls. - Irritation parameter:

- Irritant / corrosive response data:
- Irritation: Four hours exposure to 0.5 ml of HATCOL 3344 resulted in very slight erythema in the treated skin-areas of the three rabbits. The skin irritation had resolved within 24 hours after exposure in all animals.
Corrosion: There was no evidence of a corrosive effect on the skin. - Other effects:
- Colouration: No staining of the treated skin by the test substance was observed. Fatty remnants of the test substance were present immediately after removal of the bandage.
Toxicity/Mortality: No symptoms of systemic toxicity were observed in the animals during the test period and no mortality occurred. - Interpretation of results:
- GHS criteria not met
- Conclusions:
- Based on the results HATCOL 3344 does not have to be classified and has no obligatory labelling requirement for skin irritation.
- Executive summary:
Primary skin irritation/corrosion study with HATCOL 334 in the rabbit (4-hour semi-occlusive application).
The study was carried out based on the guidelines described in: EC Commission Directive 92/69/EEC, B.4, "Acute Toxicity - Skin Irritation", OECD No 404, "Acute Dermal Irritation/Corrosion", US EPA, OPPTS 870.2500, Acute Dermal Irritation and JMAFF JapaneseTest Guidelines.
Three rabbits were exposed to 0.5 ml of HATCOL 3344, applied onto clipped skin for 4 hours using a semi-occlusive dressing. Observations were made 1, 24, 48 and 72 hours after exposure.
Exposure to HATCOL 334 resulted in very slight erythema in the treated skin-areas of the rabbits, which had resolved within 24 hours.
Fatty remnants of the test substance were present immediately after removal ofthe bandage.
Based on the results and according to the EC criteria for classification and labellingrequirements for dangerous substances and preparations (Council Directive 67/548/EEC), HATCOL 3344 does not have to be classified and has no obligatory labelling requirement for skin irritation.

- Irritant / corrosive response data:
- Irritation: Instillation of 0.1 ml of the test substance into one eye of each of three rabbits resulted in irritation of the conjunctivae, which was seen as redness and chemosis. The Irritation had completely resolved within 24 hours In all animals.
No iridial irritation or corneal opacity was observed and treatment of the eyes with 2% fluorescein, 24 hours after test substance instillation revealed no corneal epithelial damage in any of the animals.
Corrosion: There was no evidence of ocular corrosion. - Other effects:
- Colouration/Remnants: No staining was observed and no remnants of the test substance were seen on (peri) ocular tissues.
Toxicity/Mortality: No symptoms of systemic toxicity were observed in the animals during the test period and no mortality occurred. - Interpretation of results:
- GHS criteria not met
- Conclusions:
- Based on the results HATCOL 334 does not have to be classified and has no obligatory labelling requirement for eye irritation.
- Executive summary:
Acute eye irritation/corrosion study with HATCOL 3344 in the rabbit.
The study was carried out based on the guidelines described in: EC Commission Directive 92/169/EEC, B.5, "Acute Toxicity - Eye irritation", OECD No 405, "Acute Eye Irritation/Corrosion" and US EPA, OPPTS 870.2400, Acute Eye Irritation, EPA 712-C-98-195, August 1998.
Single samples of 0.1 ml of HATCOL 334 were instilled into one eye of each of three rabbits.
Observations were made 1, 24, 48 and 72 hours after instillation.
Instillation of the test substance resulted in irritation of the conjunctivae, which was seen as redness and chemosis. The irritation had completely resolved within 24 hours in all animals.
Based on these results and according to the EC criteria for classification and labelling requirements for dangerous substances and preparations (Council Directive 67/548/EEC), HATCOL 334 does not have to be classified and has no obligatory labelling requirement for eye irritation.

Additional information
HATCOL 5236
In Vivo Skin Irritation: Three rabbits were exposed to 0.5 ml of HATCOL 5236, applied onto clipped skin for 4 hours using a semi-occlusive dressing. Observations were made 1, 24, 48 and 72 hours after exposure. Four hours exposure to 0.5 ml of HATCOL 5236 resulted in very slight erythema in the treated skin-areas of the three rabbits. The skin irritation had resolved within 1 day after exposure in all animals.
Based on the results, HATCOL 5236 does not have to be classified and has no obligatory labelling requirement for skin irritation.
In Vivo Eye Irritation: Single samples of 0.1 ml of HATCOL 5236 were instilled into one eye of each of three rabbits. Observations were made 1, 24, 48 and 72 hours after instillation.
Instillation of 0.1 ml of the test substance into one eye of each of three rabbits resulted in irritation of the conjunctivae, which was seen as redness on day 1. Based on the results, HATCOL 5236 does not have to be classified and has no obligatory labelling requirement for eye irritation.
HATCOL 3344
In Vivo Skin Irritation: Three rabbits were exposed to 0.5 ml of HATCOL 3344, applied onto clipped skin for 4 hours using a semi-occlusive dressing. Observations were made 1, 24, 48 and 72 hours after exposure.
Exposure to HATCOL 3344 resulted in very slight erythema in the treated skin-areas of the rabbits, which had resolved within 24 hours. Fatty remnants of the test substance were present immediately after removal of the bandage.
Based on the results,HATCOL 3344 does not have to be classified and has no obligatory labelling requirement for skin irritation.
In Vivo Eye Irritation: Single samples of 0.1 ml of HATCOL 334 were instilled into one eye of each of three rabbits. Observations were made 1, 24, 48 and 72 hours after instillation. Instillation of the test substance resulted in Irritation of the conjunctivae, which was seen as redness and chemosis. The irritation had completely resolved within 24 hours in all animals.
Based on the results, HATCOL 3344 does not have to be classified and has no obligatory labelling requirement for eye irritation.
HATCOL 3331:
In Vivo Skin Irritation/Corrosion: Primary skin irritation/corrosion study with HATCOL 3331 in the rabbit (4-hour semi-occlusive application). Three rabbits were exposed to 0.5 ml of HATCOL 3331, applied onto clipped skin for 4 hours using a semi-occlusive dressing. Observations were made 1, 24, 48 and 72 hours after exposure.
Exposure to HATCOL 3331 resulted in very slight erythema and/or very slight oedema in the treated skin-areas of the rabbits, which had resolved within 24 hours in two animals and within 48 hours in the other animal. Sticky remnants of the test substance were present on the edges of the treated skin area on day 1.
Based on the results, HATCOL 3331 does not have to be classified and has no obligatory labelling requirement for skin irritation.
In Vivo Eye Irritation: Single samples of 0.1 ml of HATCOL 3331 were instilled into one eye of each of three rabbits. Observations were made 1, 24, 48 and 72 hours after instillation.
Instillation of the test substance resulted in irritation of the conjunctivae, which was seen as redness and chemosis. The irritation had completely resolved within 24 hours in all animals.
Based on the results, HATCOL 3331 does not have to be classified and has no obligatory labelling requirement for eye irritation.

Skin irritation
The skin irritation of potential of PE/TMP tetra/tri C5, i-C5, C7, C8, i-C9, C10 ester was investigated according to OECD Guideline 404 (Allen, 1998). Three males New Zealand White rabbits were exposed to 0.5 mL unchanged test material for 4 h. The rabbits were observed for 7 days. Skin reactions were assessed using the Draize scheme 1, 24, 48, and 72 h after removal of the test substance. The exposure period of 4 h resulted in a very slight erythema observed at two treated skin sites at 1h observation time. Very slight to well-defined erythema was noted at all treated skin sites at the 24 h observation time. Very slight erythema was noted at one treated skin site at 48 and 72 h observation time. Very slight oedema was noted at one treated skin site at the 1 and 24 h observation time. All treated skin sites appeared normal (fully reversibility of the effects observed) at the 7-day observation. No edema and no further skin reactions were noted in any animal. The mean erythema score of animal 1, 2, and 3 over 24, 48 and 72 h was 0.3, 1.3 and 0.3 respectively. The mean oedema score of animals 1, 2, and 3 was 0, 0.3 and 0.
Thus, under the test conditions the test substance was considered to be not irritating to the skin.
Eye irritation
One animal study investigating the eye irritation potential of PE/TMP tetra/tri C5, i-C5, C7, C8, i-C9, C10 ester is available. An acute eye irritation study was conducted with the test substance according to OECD Guideline 405 (Allen, 1998). The undiluted test substance was instilled into the conjunctival sac of one eye of three New Zealand White rabbits for 24 h. The second eye served as negative control. The animals were observed for three days. Reactions on the eye were assessed using the Draize scheme 1, 24, 48, and 72 h after treatment. No effects were observed in all animals tested.
Therefore, under the test conditions the test substance was considered to be not irritating to the eye.
Justification for classification or non-classification
The read across for substance, CAS: 156558-98-4; EC: 451-190-0; is based upon the analogous substances to which basic form, degree of substitution of functional groups is not considered to effect the proposed read across for the endpoint of skin corrosion/irritation and eye damage/irritation. The substances is not considered to meet the criteria for skin corrosion/irritation or eye damage/irritation on the basis of the read across.
