HEALTH HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
1 Acute toxicity （Oral） Category 4 Warning H302: Harmful if swallowed P301+P312: IF SWALLOWED: Call a POISON CENTER or doctor/physician if you feel unwell.
P264: Wash ... thoroughly after handling.
P270: Do not eat, drink or smoke when using this product.
P330: Rinse mouth.
P501: Dispose of contents/container to ... 		Based on the LD50 value of 438mg/kg calculated from the testing data of rat LD50 (oral route) of 438mg/kg (RTECS (2006)), 500mg/kg and 2,000mg/kg (IUCLID (2000)).
1 Acute toxicity （Dermal） Classification not possible - - - - No data available
1 Acute toxicity （Inhalation: Gases） Not applicable - - - - Due to the fact that the substance is "solid" according to the GHS definition and inhalation of its gas is not expected.
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 the description in the report on rabbit skin irritation tests (24 hour application) (RTECS (2006)): "Causes moderate irritation." Also based on the description in the report on rabbit skin irritation tests performed in accordance with OECD TG 404 (IUCLID (2000)): "Irritating to the skin." Although the results are not those of 4 hour application, the substance is considered to be a moderate irritant and classified into Category 2.
3 Serious eye damage/eye irritation Category 2A Warning H319: Causes serious eye irritation P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing.
P337+P313: If eye irritation persists: Get medical advice/attention.
P264: Wash ... thoroughly after handling.
P280: Wear protective gloves/protective clothing/eye protection/face protection. 		Based on the description in the report on rabbit eye irritation tests (RTECS (2006)): "24 hour application of 250microg induced severe irritation reactions," "1% solution produced severe irritation." Also based on the description in the report on rabbit eye irritation tests performed in accordance with OECD TG 405 (IUCLID (2000)): "Irritating to the eye." The substance is thus considered a severe eye irritant.
4 Respiratory sensitization Classification not possible - - - - No data available
4 Skin sensitization Category 1 Warning H317: May cause an allergic skin reaction P302+P352: IF ON SKIN: Wash with plenty of soap and water.
P333+P313: If skin irritation or rash occurs: Get medical advice/attention.
P261: Avoid breathing dust/fume/gas/mist/vapours/spray.
P272: Contaminated work clothing should not be allowed out of the workplace.
P280: Wear protective gloves/protective clothing/eye protection/face protection.
P321: Specific treatment （see ... on this label）.
P363: Wash contaminated clothing before reuse.
P501: Dispose of contents/container to ... 		Based on the description in the report on guinea pig skin sensitization tests (CERI Hazard Data 2001-20 (2002) and CERI-NITE Hazard Assessment No.5 (2004)): "Skin sensitization: positive" (linear alkylbenzenesulfonate and its salts (the carbon chain length unknown); No data available on sodium dodecylbenzenesulphonate per se).
5 Germ cell mutagenicity Classification not possible - - - - Classification not possible due to the insufficiency of data (no definite data are available regarding sodium dodecylbenzenesulphonate per se). As for linear alkylbenzene sulphonate (LAS) and its salts [carbon chain lengths of 10-14 and their mixtures], no data are available on germ cell mutagenicity tests in vivo, whereas multi-generation mutagenicity tests (dominant lethal tests), somatic cell mutagenicity tests in vivo (micronucleus tests, chromosome aberration tests) and Ames assay gave negative results, described in NTP DB (Access on June, 2006), CERI-NITE Hazard Assessment No.5 (2005) and EHC 169 (1996).
6 Carcinogenicity Classification not possible - - - - Classification not possible based on expert judgment in the absence of existing classification together with the absence of definite data on sodium dodecylbenzenesulphonate per se. CERI-NITE Hazard Assessment No.5 (2005) presents some data regarding carcinogenicity studies on linear alkylbenzene sulphonate (LAS) and its salts [carbon chain lengths of 10-14 and their mixtures].
7 Reproductive toxicity Classification not possible - - - - Classification not possible due to the insufficiency of data (no definite data are available regarding sodium dodecylbenzenesulphonate per se). As for linear alkylbenzene sulphonate (LAS) and its salts [carbon chain lengths of 10-14 and their mixtures], there was no evidence of adverse effects on the parental animals and the offspring observed in oral studies, whereas decreased fertility and increased incidence of malformation in the offspring were observed at doses inducing parental toxicity in dermal studies, described in CERI-NITE Hazard Assessment No.5 (2005) and EHC 169 (1996).
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 the description in ICSC (J) (1997): "Causes respiratory irritation." Note: As for linear alkylbenzene sulphonate (LAS) and its salts [carbon chain lengths of 10-14 and their mixtures], "clinical symptoms include confusion, vomiting, pharyngal and oral pains, and the tendency of blood pressure to decrease" (NITE Initial Risk Assessment No.5 (2005)).
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - - Classification not possible due to the fact that the only available data are those for mixtures of C10-14.
10 Aspiration hazard Classification not possible - - - - No data available

ENVIRONMENTAL HAZARDS

11 Hazardous to the aquatic environment （Acute） Category 1 Warning H400: Very toxic to aquatic life P273: Avoid release to the environment.
P391: Collect spillage.
P501: Dispose of contents/container to ... 		It was classified into Category 1 from 96 hours EC50=0.9mg/L of the blue algae (Microcystis) (EHC169, 1996).
11 Hazardous to the aquatic environment （Long-term） Not classified - - - - Since there was rapidly degrading (the decomposition of p-n-dodecylbenzenesulfonic acid sodium salt by BOD: 73% (Existing Chemical Safety Inspections Data)) and the bio-accumulation was low (log Kow=1.96(PHYSPROP Database, 2005)), it was claasified into Not classified.
