HEALTH HAZARDS

Hazard class		Classification	Pictogram Signal word	Hazard statement (code)	Precautionary statement (code)	Rationale for the classification
1	Acute toxicity (Oral)	Classification not possible	- -	-	-	Classification not possible due to lack of data.
1	Acute toxicity (Dermal)	Classification not possible	- -	-	-	Classification not possible due to lack of data.
1	Acute toxicity (Inhalation: Gases)	Not applicable	- -	-	-	Liquid (GHS definition)
1	Acute toxicity (Inhalation: Vapours)	Classification not possible	- -	-	-	Classification not possible due to lack of data.
1	Acute toxicity (Inhalation: Dusts and mists)	Not classified	- -	-	-	Based on an LC50 value (4 hours) of 118 mg/L for rats (PATTY (6th, 2012)), this substance was classified as "Not classified." Besides, since the LC50 value was higher than the saturated vapour pressure concentration (61.3 mg/L), the reference value for a mist was applied.
2	Skin corrosion/irritation	Category 2	Warning	H315	P302+P352 P332+P313 P362+P364 P264 P280 P321	There is a report that in a test with volunteers, in which this substance was applied on the forearm for 1 hour and on the thigh for 5 hours, hyperemia, inflammation and pigmentation occurred with a burning and itching sensation at the site of application (PATTY (6th, 2012)). It is also described that after the 5-hour application, blister formation was observed but this disappeared (HSDB (Access on July 2014)). Based on the above, this substance was classified in Category 2.
3	Serious eye damage/eye irritation	Category 2	Warning	H319	P305+P351+P338 P337+P313 P264 P280	Although no report on the eye irritation was available, it was classified in Category 2 for the skin irritation. Besides, this substance is a hydrocarbon and it was described that mild to moderate eye irritation and reversible ocular injury may occur (HSDB (Access on July 2014)), therefore, this substance was classified in Category 2.
4	Respiratory sensitization	Classification not possible	- -	-	-	Classification not possible due to lack of data.
4	Skin sensitization	Classification not possible	- -	-	-	Classification not possible due to lack of data.
5	Germ cell mutagenicity	Classification not possible	- -	-	-	Classification not possible due to lack of data.
6	Carcinogenicity	Classification not possible	- -	-	-	Classification not possible due to lack of data.
7	Reproductive toxicity	Classification not possible	- -	-	-	Classification not possible due to lack of data.
8	Specific target organ toxicity - Single exposure	Category 3 (respiratory tract irritation, narcotic effects)	Warning	H335 H336	P304+P340 P403+P233 P261 P271 P312 P405 P501	This substance is irritating to the nose and throat (ACGIH (7th, 2001), PATTY (6th, 2012), HSDB (Access on June 2014)). In addition, there are descriptions of narcotic effects (ACGIH (2001), PATTY (6th, 2012)) and convulsions (HSDB (Access on June 2014)) when exposed to high concentrations. There are reports of cardiac arrest, respiratory paralysis, convulsions, asphyxiation and death in rats exposed to 0.2 mL (no detailed description) of this substance by inhalation, lateral position at 31 mg/L and loss of reflex at 44 mg/L in inhalation exposure of mice, narcotic effects at 6,600–13,700 ppm in inhalation exposure of mice, and respiratory arrest at 16,000 ppm and 32,000 ppm in inhalation exposure of mice (OEL Documentations (Japan Society For Occupational Health (JSOH), 1989), PATTY (6th, 2012), ACGIH (7th, 2001), HSDB (Access on June 2014)). From the above, it is considered that this substance causes respiratory tract irritation and narcotic effects, and it was classified in Category 3 (respiratory tract irritation, narcotic effects).
9	Specific target organ toxicity - Repeated exposure	Classification not possible	- -	-	-	Classification not possible due to lack of data.
10	Aspiration hazard	Category 1	Danger	H304	P301+P310 P331 P405 P501	Since this substance is a hydrocarbon with 0.7373 of kinematic viscosity (calculated using the viscosity and the density (at 25 deg C, respectively)) described in HSDB (Access on June 2014) and there was a description that chemical pneumonitis was caused due to aspiration, which is common in hydrocarbons, in humans (HSDB (Access on June 2014)), it was classified in Category 1.

11	Hazardous to the aquatic environment (Long-term)	Category 2	-	H411	P273 P391 P501	It was classified in Category 2 due to rapid degradability (it is rapidly degradable from the test results in which 70% degradation was measured after 10 days with unacclimated sewage sludge and so on (SIDS, 2010)), and NOEC = 0.028 mg/L for fish (Oryzias latipes) in an early life stage test (Results of Aquatic Toxicity Tests of Chemicals conducted by Environment Agency in Japan (Environment Agency, 1998)).
