- Executive summary:
In a primary dermal irritation study conducted according to OECD 404 without compliance in GLP, three rabbits were exposed to 0.5 mL of Petrepar-147. Test sites were covered with a semi-occlusive dressing for 4 hours. Animals then were observed for 10 days. The skin reactions were assessed at 1, 24, 48 and 72 hours, as well as 5 and 10 days after removal of the dressing. The mean score was calculated across 3 scoring times; 24, 48 and 72 hours after patch removal, for each animal separately.
The mean individual scores were 0.67, 0.67, 2.0 for erythema and 0.00, 0.67, 1.33 for edema. Skin reactions were totally reversible at day 10. Petrepar-147 is slightly irritating.
Based upon the directive 67/548/EEC and the CLP Regulation 1272/2008, Petrepar-147 is not considered as irritating to the rabbit skin.

Additional information
There is skin/eye irritation data available for Hydrocarbons, C14-C17, n-alkanes, <2% aromatics, as well as for structural analogues, Hydrocarbons, C14 -C19, isoalkanes, cyclics, <2% aromatics and isohexadecane. This data is read across to Hydrocarbons, C14 -C17, n-alkanes, <2% aromatics based on analogue read across and a discussion and report on the read across strategy is provided as an attachment in IUCLID Section 13.
Skin irritation
Hydrocarbons, C14 -C17, n-alkanes, <2% aromatics
In a primary dermal irritation study (Petroquimica, 1984) conducted according to OECD 404 without compliance in GLP, three rabbits were exposed to 0.5 mL of Petrepar-147. Test sites were covered with a semi-occlusive dressing for 4 hours. Animals then were observed for 10 days. The skin reactions were assessed at 1, 24, 48 and 72 hours, as well as 5 and 10 days after removal of the dressing. The mean score was calculated across 3 scoring times; 24, 48 and 72 hours after patch removal, for each animal separately. The mean individual scores were 0.67, 0.67, 2.0 for erythema and 0.00, 0.67, 1.33 for edema. Skin reactions were totally reversible at day 10. Petrepar-147 is slightly irritating.
Hydrocarbons, C14 -C19, isoalkanes, cyclics, <2% aromatics
In a primary dermal irritation study conducted according to OECD guideline N°404, six young adult male New Zealand White rabbits were dermally exposed to 0.5 mL of MRD-94 -974 (ExxonMobil, 1995). Test sites were covered with a semi-occlusive dressing for 4 hours. The skin reactions were assessed at 1, 24, 48 and 72 hours after removal of the dressing. The mean score was calculated across 3 scoring times for all animals at 24, 48 and 72 hours after patch removal. The mean scores over 24, 48 and 72 hours were 0.0 for erythema and for oedema.
Isohexadecane
In a clinical test including 15 human volunteers, isohexadecane was applied undiluted on upper arm in occlusive consitions (patch) for 24 h. Skin reactions were scored 30 min and 24 h after removal of the patch. Mild signs of irritation were observed in only 3 volunteers and only slight signs of irritation in 8 volunteers in worse conditions (24-h exposure, occlusive conditions), leading to the conclusion that isohexadecane is not irritant for human skin (Hill Top Research, 1994a).
The skin irritating properties of the substance BP solvent IH/isohexadecane was assessed in White Vienna rabbits (3 animals of both sexes). The test substance was applied on a wipe put in contact with the shaved skin under semi-occlusive dressing for 24 hours. At the end of exposure, skin reactions were recorded both at 24 hours (patch removal) and 48 hours after the end of exposure (i.e. 72 -hour time observation) according to the Draize scale. Complete observation time was 14 days. No systemic effect was observed following exposure to BP Solvent IH/Isohexadecan. Behavior, general state, fur, food consumption and body weight development were normal (INEOS, 1980).
Eye irritation
Hydrocarbons, C14 -C17, n-alkanes, <2% aromatics
The eye irritant effect of Petrepar-147 was investigated according to the OECD Guideline No. 405 (1981). Three albino rabbits were exposed to 0.1 mL of the test article in one eye. The eyes were examined and the changes were graded according to a numerical scale 1, 24, 48 and 78 hrs and on day 4 and 7 after dosing. The eyes were not rinsed after administration of the test substance. No corneal damage or iridal inflammation was observed. Redness and chemosis were observed in all animals, one hour after instillation. Slight redness was still observed in two animals at 24 hours while slight chemosis was only observed in one rabbit. The eyes of all rabbits were normal 48 hours after instillation. The mean individual scores were 0.33/0.33/0.0 for conjunctival redness and 0.33/0.0/0.0 for chemosis (Petroquimica, 1984).
Isohexadecane
The irritant potential of the substance BP Solvent IH/Isohexadecane was assessed by applying 0.1 mL of the test substance in the conjunctival sac of the left eye of 6 male Himalayan rabbits (INEOS, 1980). After application the animals lid were kept closed for 1 second. The right eye was used as control and received 0.1 mL of physiological NaCl solution. The eyes were examined and the changes were graded according to a numerical scale at 15 min, 1, 24, 48 and 72 hours after dosing. No conjunctival chemosis, corneal and iridal lesion were observed throughout the observation period. Slight redness of the conjunctivae was observed in all animals at 1 hour but only in one animal by the 24 hours after instillation. At 48-hour observation period, no redness was observed in any rabbit. Hence, the mean individual score for redness was 0.33-0.0-0.0.
Respiratory Irritation:
no studies available
Justification for classification or non-classification
Skin Irritation:
Based on available read across data, Hydrocarbons, C14-C17, n-alkanes, <2% aromatics does not meet the criteria for classification for skin Irritation under the new Regulation (EC) 1272/2008 on classification, labeling and packaging of substances and mixtures (CLP).
Eye Irritation:
Based on available read across data, Hydrocarbons, C14-C17, n-alkanes, <2% aromatics does not meet the criteria for classification as an ocular irritant under the new Regulation (EC) 1272/2008 on classification, labeling and packaging of substances and mixtures (CLP).
Respiratory Irritation:
There are no studies that warrant classification as a respiratory irritant under the new Regulation (EC) 1272/2008 on classification, labeling and packaging of substances and mixtures (CLP).
