- Executive summary:
Key data is available for propylene glycol dibenzoate (PGDB). This data is supported by relevant information available from a structural analogue Dipropylene glycol dibenzoate (DPGDB). The justification for read across is presented as an attachment included in Section 13 of the IUCLID dossier.
A study was performed to assess the skin irritation potential of DPGDB to the rabbit. The study was conducted in accordance with OECD, EC, US EPA and Japanese test guidelines, and in compliance with GLP.
Approximately 0.5 mL of the test substance was applied under a semi-occlusive gauze pad to 6 rabbits; after a period of 4 hours the application site was washed with physiological saline. The animals were then observed for a period of 72 hours.
No dermal reactions were observed following this single semi-occlusive application of DPGDB to intact rabbit skin for four hours. There were no signs of toxicity or ill health in any of the rabbits during the observation period.
Therefore DPGDB is not irritating to the skin and is not considered to be a primary skin irritant.
