HEALTH HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
1 Acute toxicity (Oral) Not classified - - - - Based on a LD50 value of 13050 mg/kg for rats (JECFA No. 101 (1967)), the substance was classified into "Not classified".
1 Acute toxicity (Dermal) Classification not possible - - - - Classification not possible due to lack of data. As relevant information, a LD50 value is >2 mg/kg for rabbits (RTECS (1997)).
1 Acute toxicity (Inhalation: Gases) Not applicable - - - - Liquid (GHS definition)
1 Acute toxicity (Inhalation: Vapours) Classification not possible - - - - No data available.
1 Acute toxicity (Inhalation: Dusts and mists) Classification not possible - - - - No data available.
2 Skin corrosion/irritation Category 2 Warning H315: Causes skin irritation P302+P352: IF ON SKIN: Wash with plenty of soap and water.
P332+P313: If skin irritation occurs: Get medical advice/attention.
P264: Wash ... thoroughly after handling.
P280: Wear protective gloves/protective clothing/eye protection/face protection.
P321: Specific treatment (see ... on this label).
P362: Take off contaminated clothing and wash before reuse.
Based on a report of "irritating to skin" (HSDB (2002)), the substance was classified into Category 2. As relevant information, there is a report that 5% in petrolatumin produced no irritation after a 48 hr closed-patch test in 25 human subjects (HSDB (2002)).
3 Serious eye damage/eye irritation Classification not possible - - - - Although the substance is reportedly irritating to mucous membranes (PATTY (5th, 2001)), the substance was classified as "Classification not possible" since the original literature can not be confirmed and the details are not clear.
4 Respiratory sensitization Classification not possible - - - - No data available.
4 Skin sensitization Classification not possible - - - - Classification not possible due to lack of data. As relevant information, there is a report that no skin sensitization was noted in a maximization test on 25 volunteers (HSDB (2002)).
5 Germ cell mutagenicity Classification not possible - - - - Classification not possible due to lack of data from in vivo mutagenicity tests. From in vitro mutagenicity tests, there is a report of a negative Ames test (NTP DB (access on Aug. 2009)).
6 Carcinogenicity Classification not possible - - - - No data available.
7 Reproductive toxicity Classification not possible - - - - No data available.
8 Specific target organ toxicity - Single exposure Category 3 (Respiratory tract irritation) Warning H335: May cause respiratory irritation (respiratory tract irritation) P304+P340: IF INHALED: Remove victim to fresh air and keep at rest in a position comfortable for breathing.
P403+P233: Store in a well-ventilated place. Keep container tightly closed.
P261: Avoid breathing dust/fume/gas/mist/vapours/spray.
P271: Use only outdoors or in a well-ventilated area.
P312: Call a POISON CENTER or doctor/physician if you feel unwell.
P405: Store locked up.
P501: Dispose of contents/container to ...
Based on reports that the substance is reportedly irritating to mucous membranes (PATTY (5th, 2001)) and that vapour is irritating to nose and throat (HSDB (2002)), the substance was classified into Category 3 (respiratory tract irritation).
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - - There is a report that no adverse effects were observed at 14.4 mg/kg/day in a rat 12-week feeding test (JECFA No. 101 (1967). This dose level is within the guidance value range. However, effects at higher dose levels are not clear, therefore, classification was not possible.
10 Aspiration hazard Classification not possible - - - - No data available.

ENVIRONMENTAL HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
11 Hazardous to the aquatic environment (Acute) Not classified - - - - Classified into Not classified from its 24h-EC50 = 750 mg/L for Crustacea (Daphnia magna) (AQUIRE, 2010).
11 Hazardous to the aquatic environment (Long-term) Not classified - - - - Classified into Not classified since its acute toxicity is Not classified and it is not non-water soluble from water solubility = 4,900 mg/L (PHYSPROP Database, 2010).
