Additional information

Acute oral toxicity:

Based on the data available for target 3-Acetylphenol (CAS no 121-71-1) and it’s read acrossPara-Hydroxybenzoic Acid(CAS no 99-96-7) for acute oral toxicity is summarized below

Based on the prediction done by using QSAR Toolbox 3.4 (2016), acute oral toxicity was estimated in Sprague-Dawley male and female rats by using3-hydroxyacetophenone orally. 50 % mortality was observed at 3063.2 mg/kg bw in treated rats. Therefore, estimated LD50 was considered to be 3063.2 mg/kg bw whenSprague-Dawley male and female rats were treated with3-hydroxyacetophenone orally.

In a study conducted by Schafer et al (1985), acute oral toxicity was evaluated in deer Peromyscus maniculatus) mice by using 3-Acetylphenol orally by gavage using water, corn oil, or 1.0% carbopol as carriers, followed by 3-days of observations for mortality. Approximate Lethal Dose was observed between 470-1600 mg/kg bw. ALD (Approximate Lethal Dose) represented a range-finding modification of the Deichman and LeBlanc (1943) and not the LD50 determination. Using this single animal per level method, each succeeding treatment was 50% higher than the preceding level and continued until mortality occurred and No 50 % mortality was observed in treated mice at 1600 mg/kg bw. Therefore, no LD50 was considered to be 1600 mg/kg bw when deer (Peromyscus maniculatus) mice treated with 3-Acetylphenol orally by gavage.

In a study conducted by Monsanto Company (1992) for read across, acute oral single dose toxicity was evaluated in Sprague Dawley male and female rats by using Para-Hydroxybenzoic Acid; CP 4915 in the concentration of 5000 mg/kg bw orally by gavage in deionized water and observed for 14 days. No effect on survival and body weight of treated male and female rats were observed at 5000 mg/kg bw. Piloeraction and hypo- activity were observed in each for two rats; one rat displayed both signs. Seven of the ten rats on study appeared normal for the entire observation period. One-half of the rats bad mild to moderate multifocal red foci on their Kidneys at the terminal post-mort were observed This was bilateral in all eases and vas the on1y finding noted. The remaining five rats had no visible abnormalities. Therefore, LD50 was considered to be >5000 mg/kg bw when Sprague Dawley male and female rats were treated with Para-Hydroxybenzoic Acid; CP 4915 orally by gavage in deionized water.

Thought, the LD50 value for target3-Acetylphenol (CAS no 121-71-1)is from prediction and LD0 is considered as 1600 mg/kg bw. The read across which is 60-70% similar (Para-Hydroxybenzoic Acid) were also having LD50 > 5000 mg/kg bw.

Thus, based on weight of evidence fortarget 3-Acetylphenol (CAS no 121-71-1) and it’s read acrossPara-Hydroxybenzoic Acid(CAS no 99-96-7) is likely o be non hazardous by oral route of exposure as per the criteria of CLP regulation.

Justification for selection of acute toxicity – oral endpoint
