Besides, a test in which rats were orally dosed a mixture of 3 ethylphenol isomers including 25.9% of this substance (OECD TG 425, GLP) reported that signs such as hypersalivation, blepharoptosis, decreased spontaneous motility, ataxia, tachypnea, righting reflex, anomalies in limbs observed at 1750 mg/kg immediately after dosing disappeared by seven days after administration. (USEPA/HPV (2006)) In addition, an oral dose of 2000 mg/kg of 4-ethylphenol in rats reported that no death in both males and females was observed and observed signs of staggering gait followed by proneness or recumbency, and tachypnea disappeared by 2 hours after dosing. After that, no symptoms by day 14 and no dose-related abnormalities in both males and females in necropsy were observed.

9	Specific target organ toxicity - Repeated exposure	Classification not possible	- -	-	-	No data. Besides, in a combined repeated dose toxicity test with reproductive/developmental toxicity screening test (OECD TG 422, GLP) in which rats were orally administered a mixture of 3 isomers at 30 to 245 mg/kg/day including this substance, no dose-related effects except dirty hair, decreases in food consumption and a weight gain in males, and salivation in females were reported. (US EPA HPV (2006)) In addition, in a 28-day repeated oral administration test of 4-ethylphenol to rats, increased liver weight, squamous cell hyperplasia of a forestomach in pathological histology at 300mg/kg or higher, and additionally, staggering gait, symptoms like salivation, low body weight and food consumption, and increased kidney weight at 1000 mg/kg were observed. All changes recovered or showed recovery tendencies at the end of a recovery period. NOELs under conditions of this test were reported 100 mg/kg/day for males (converted to a 90-day equivalent: 31.1 mg/kg/day) and 300 mg/kg/day for females (converted to a 90-day equivalent: 93.3 mg/kg/day).

This GHS classification was conducted based on the information sources and the guidance for classification and judgement which are described in the GHS Classification Guidance for the Japanese Government etc. Using other literature, test results etc. as evidence and including different content from this classification result in a label or SDS are allowed.
Hazard statement and precautionary statement will show by hovering the mouse cursor over a code in the column of "Hazard statement" and "Precautionary statement," respectively. In the excel file, both the codes and statements are provided.
A blank or "-" in the column of "Classification" denotes that a classification for the hazard class was not conducted in the year.
An asterisk “*” in the column of “Classification” denotes that “Not classified (or No applicable)” and/or “Classification not possible” is applicable. Details are described in the column of “Rationale for the classification”.
