Additional information

Acute oral toxicity:

Based on the data available for target 1,2-Benzenedicarboxylic acid, monopotassium salt (CAS no 877-24-7) and its read across Phthalic acid (CAS no 88-99-3) is summarized below

In a study given by RTECS database (2017) and SAX: Chemical Card (2012), acute oral toxicity was given for rats by using 1,2-Benzenedicarboxylic acid, monopotassium salt in the concentration of 3200 mg/kg bw. No mortality was observed in treated rats at 3200 mg/kg bw. Therefore, LD50 was considered to >3200 mg/kg bw when rats were treated with 1,2-Benzenedicarboxylic acid, monopotassium salt orally.

Based on the prediction done by using QSAR Toolbox 3.4 (2017), acute oral toxicity was estimated in rats by using potassium biphthalate orally. 50 % mortality was observed at 4447.6 mg/kg bw in treated rats. Therefore, estimated LD50 was considered to be 4447.6 mg/kg bw when rat were treated with potassium biphthalate orally.

Based on the prediction done by using Danish QSAR (2017), acute oral toxicity was estimation done by in mice and rats by using potassium hydrogen phthalate at 2400 and 3500 mg/kg bw orally. 50 % mortality was observed at 2400 and 3500 mg/kg bw. Therefore, estimated LD50 was considered to be 2400 mg/kg bw for mice and 3500 mg/kg bw for rats when mice and rat were treated with potassium hydrogen phthalate orally.

In a study conducted by Schonekeret al(2003) for read across, acute oral toxicity was evaluated in Albino male and female mice by using Phthalic acid in the concentration of 5000 mg/kg bw orally by gavage in 5% gum acacia. No mortality was observed in treated mice at 5000 mg/kg bw. CNS depression and Inflammation of the gastrointestinal tract was observed in treated mice. Therefore, LD50 was considered to >5000 mg/kg bw when Albino male and female mice were treated with Phthalic acid orally by gavage.

Based on the data available for target 1, 2-Benzenedicarboxylic acid, monopotassium salt (CAS no 877-24-7) and its read across Phthalic acid (CAS no 88-99-3) is likely to be non hazardous by oral route of exposure.

Justification for classification or non-classification

Based on the data available for target 1, 2-Benzenedicarboxylic acid, monopotassium salt (CAS no 877-24-7) and its read across Phthalic acid (CAS no 88-99-3) is likely to be non hazardous by oral route of exposure.
