Based on the rat LD50 (oral route) value of 650mg/kg representing the lower of the two testing data, 650mg/kg (RTECS (2006)) and 1,260mg/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 "liquid" or "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 ICSC (2002) of the human health effects: "redness, pains, skin burn and bullae." The substance is classified into Category 2 because the severity of the effects is unknown.
3 Serious eye damage/eye irritation Category 1 Danger H318: Causes serious eye damage P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing.
P280: Wear protective gloves/protective clothing/eye protection/face protection.
P310: Immediately call a POISON CENTER or doctor/physician.
Based on the description in ICSC (2002) of the human health effects: "redness, pains, skin burn and blindness."
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.

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 dodecylbenzenesulphonic acid per se).
5 Germ cell mutagenicity Classification not possible - - - - Classification not possible due to the insufficiency of data (no definite data are available regarding dodecylbenzenesulphonic acid 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 dodecylbenzenesulphonic acid 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 dodecylbenzenesulphonic acid 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 2 (respiratory system) Warning H371: May cause damage to organs (respiratory system) P309+P311: IF exposed or if you feel unwell: Call a POISON CENTER or doctor/physician.
P260: Do not breathe dust/fume/gas/mist/vapours/spray.
P264: Wash ... thoroughly after handling.
P270: Do not eat, drink or smoke when using this product.
P405: Store locked up.
P501: Dispose of contents/container to ...
Based on the description in (ICSC (J) (2002)): "Corrosive to the respiratory tract; oral ingestion results in corrosion." Since the priority rating of ICSC (J) is 2, the effects are classified into Category 2. 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

It was classified into Category 2 from 48 hours LC50=3.5mg/L of the crustacea (Daphnia magna) (EHC169 (1996) and others.). [NOTE]Since it may show same behavior of sodium salt in the environment, it was classified by the data of sodium dodecylbenzenesulfonate(C12).
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. [NOTE]Since it may show same behavior of sodium salt in the environment, it was classified by the data of sodium dodecylbenzenesulfonate(C12).
