Description of key information
There were no deaths in acute toxicity tests with Santicizer 261, either in rats (oral, given up to 15.8 g/kg bw) or rabbits (dermal, 24-hour application of up to 7.94 g/kg bw). Studies only available in a brief summary report (reliability code 4), but data considered adequate for assessment. Results indicate that S261 does not need to be classified for acute toxicity. Additional acute toxicity data on high molecular-weight phthalates provide support for this conclusion (OECD, 2004. Draft SIDS Initial Assessment Report on High Molecular Weight Phthalate Esters (HMWPE) category).

- Executive summary:
Undiluted Santicizer 261 was orally administered to two male and three female Sprague-Dawley rats at 15.8 g/kg bw. The animals were assessed for toxic symptoms, and the survivors sacrificed 14 days after dosing and examined macroscopically.
All five animals survived the 14-day observation period. Reduced appetite and activity were seen for one to two days (numbers of animals not given). At necropsy, the viscera of all animals appeared normal. The investigators concluded that the LD50 was greater than 15.8 g/kg bw. Under the EU CLP regulations, this study would indicate that Santicizer 261 is not classified for acute oral toxicity.

- Executive summary:
Undiluted Santicizer 261 was applied to the skin of a total of three New Zealand white rabbits. One male was dosed at each of 5.01 and 7.94 g/kg bw, and one female dosed at 7.94 g/kg bw, for an exposure period of 24 hours. The animals were assessed for toxic symptoms during the observation period, and the surviving animals sacrificed 14 days after dosing and examined macroscopically.
All three animals survived the 14-day observation period. Reduced appetite and activity was seen for one to three days (no details on number of animals or doses given). At necropsy, the viscera appeared normal. The investigators concluded that the LD50 was greater than 7.94 g/kg bw. Under the EU CLP regulations, this study would indicate that Santicizer 261 is not classified for acute dermal toxicity.

Additional information
Two acute toxicity studies have been conducted on Santicizer 261, one oral and one dermal (Younger Laboratories, 1976a,b). Although details of the two studies are only available in a brief summary report (hence they have been assigned reliability code 4), the data are considered adequate for assessment.
The oral administration of undiluted Santicizer 261 to two male and three female Sprague-Dawley rats at 15.8 g/kg bw resulted in reductions in appetite and activity for 1-2 days after dosing, but all five rats survived the 14-day observation period. At necropsy, the viscera of all animals appeared normal. The investigators concluded that the oral LD50 was greater than 15.8 g/kg bw.
The 24-hour dermal application of undiluted Santicizer 261 to three New Zealand white rabbits, at doses of 5.01 g/kg bw (one male) and 7.94 g/kg bw (one male and one female) resulted in reductions in appetite and activity for 1-3 days, but all three rabbits survived the 14-day observation period. At necropsy, the viscera of all animals appeared normal. The investigators concluded that the dermal LD50 was greater than 7.94 g/kg bw.
Additional acute toxicity data on high molecular-weight phthalate esters (HMWPE) indicate that these compounds (with a carbon backbone of C7 or greater) are of a low order of acute toxicity by the oral, dermal and inhalation routes of exposure, with LD50/LC50 values of all tested substances exceeding the maximum amounts that can be administered to test animals (OECD, 2004. Draft SIDS Initial Assessment Report on High Molecular Weight Phthalate Esters (HMWPE) category).
Justification for classification or non-classification
Two studies on Santicizer 261 (which are only available in a brief summary report, reliability code 4) are considered adequate for concluding that the substance does not need to be classified for acute oral or dermal toxicity, under the EU CLP regulations.
