All rats treated with the AP at a dose of 2000 mg/kg survived the 14-day observation period, no significant changes were observed in any organs at the necropsy on day 14. Under test conditions, the test item was found to be non-toxic by oral route, with an LD50 > 2000 mg/kg. Thus, phloridzin is considered to be non toxic, although an LD50 for phloridzin cannot be calculated.

Additional information
Oral route: Weight of evidence:
- Read-across from analogue substance. The acute oral toxicity of neohesperidin dihydrochalcone on rats was studied by a method similar to OECD TG 420. A limit test was performed by administering a single dose of 5g/kg bw test item to 10 (5M/5F) Wistar rats, and observing the effects for 14 days (clinical signs, body weights). No effects were observed in any animal. Therefore, the analogue substance was found to be non toxic, with an LD50 > 5000 mg/kg bw. Based on read-across approach, the oral LD50 in rats for the target substance was determined to be ≥ 3562 mg/kg bw.

A limit test was performed by administering a single dose of 5g/kg bw test item to 10 (5M/5F) Wistar rats, and observing the effects for 14 days (clinical signs, body weights). One male died on day 9, but no gross changes were observed, and no effects were noted on any other animal. Therefore, the analogue substance was found to be non toxic, with an LD50 > 5000 mg/kg bw. Based on read-across approach, the oral LD50 in rats for the target substance was determined to be ≥ 5000 mg/kg bw. Based on the read-across approach, the target substance is non toxic, with an LD50 > 3562 mg/kg bw.
- Supporting study: A limit test to determine the acute oral toxicity of Applephenon®, apple extract from unripe apples containing phloridzin, was coherent with the expected results. The study was performed by a method similar to OECD 420 (non-GLP). 5 male and 5 female Sprague-Dawley (Crj: CD) rats were administered a single dose of 2000 mg/kg test item by gavage and observed for 14 days. Under test conditions, the test item was found to be non-toxic by oral route, with an LD50 ≥ 2000 mg/kg. Thus, phloridzin is considered to be non toxic, although an LD50 for phloridzin cannot be calculated.
Based on the available information for the read-across approach and the supporting information, the oral LD50 of the test item in rats is ≥ 3562 mg/kg bw.
Justification for classification or non-classification
Based on available data (oral LD50 ≥ 3562 mg/kg bw in rats), the substance is not classified for acute toxity according to CLP Regulation (EC) No. 1272/2008.
