1 | Acute toxicity (Oral) | Category 4 |
Warning |
H302 | P301+P312 P264 P270 P330 P501 |
Based on the LD50 value of 502mg/kg calculated from the testing data of rat LD50 (oral route) of 404mg/kg (males), 409mg/kg (females), 659mg/kg (males), 670mg/kg (females), 760mg/kg (females) and 873mg/kg (males) (CERI-NITE Hazard Assessment No.5 (2005)). (LAS mixtures with carbon chain lengths of 10-14; no data available on undecylbenzenesulfonic acid per se). |

1 | Acute toxicity (Dermal) | Classification not possible |
- |
- | - | No data available | FY2006 | GHS Classification Manual (10 Feb, 2006) |
1 | Acute toxicity (Inhalation: Gases) | Not classified (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. |
FY2006 | GHS Classification Manual (10 Feb, 2006) |
1 | Acute toxicity (Inhalation: Vapours) | Classification not possible |

- | - | No data available | FY2006 | GHS Classification Manual (10 Feb, 2006) |
1 | Acute toxicity (Inhalation: Dusts and mists) | Classification not possible |

2 | Skin corrosion/irritation | Category 2 |
Warning |
H315 | P302+P352 P332+P313 P362+P364 P264 P280 P321 |
Based on the description in the report on human epidemiological studies (CERI-NITE Hazard Assessment No.5 (2005)): "24 hour application of 1% aqueous solution of LAS induced moderate irritation." The substance is thus considered a moderate irritant (LAS mixtures with carbon chain lengths of 10-14; no data available on undecylbenzenesulfonic acid per se). | FY2006 | GHS Classification Manual (10 Feb, 2006) |
3 | Serious eye damage/eye irritation | Category 2A |
Warning |
H319 | P305+P351+P338 P337+P313 P264 P280 |
Based on the description in the report on rabbit eye irritation tests (CERI-NITE Hazard Assessment No.5 (2005)): "Application of 5% solution produced severe congestion and edema." The substance is thus considered a severe irritant (LAS mixtures with carbon chain lengths of 11-13; no data available on undecylbenzenesulfonic acid per se). | FY2006 | GHS Classification Manual (10 Feb, 2006) |
4 | Respiratory sensitization | Classification not possible |
- |
- | - | No data available | FY2006 | GHS Classification Manual (10 Feb, 2006) |
4 | Skin sensitization | Not classified |
- |
- | - | There is one positive result in the maximization test employing guinea pig. However, it is judged as negative to humans based on two negative results in the same maximization test indicated in OECD SIDS, one negative result in the buehler test, and two negative results in the controlled or large-scale human repetition patch test. Therefore, skin sensitization is corrected from "Category 1" to "Not classified." | FY2007 | GHS Classification Manual (10 Feb, 2006)/Technical Guidance Document on the GHS Classification (6 Dec, 2005) |
5 | Germ cell mutagenicity | Classification not possible |
- |
- | - | Classification not possible due to the insufficiency of data (no definite data are available regarding undecylbenzenesulfonic 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 undecylbenzenesulfonic 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]. |
FY2006 | GHS Classification Manual (10 Feb, 2006) |
7 | Reproductive toxicity | Classification not possible |
- |
- | - | Classification not possible due to the insufficiency of data (no definite data are available regarding undecylbenzenesulfonic 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 | Classification not possible |
- |
- | - | Classification not possible in the absence of data on undecylbenzenesulfonic acid per se. 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)). |
FY2006 | GHS Classification Manual (10 Feb, 2006) |
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. | FY2006 | GHS Classification Manual (10 Feb, 2006) |
10 | Aspiration hazard | Classification not possible |

11 | Hazardous to the aquatic environment Short term (Acute) | Category 2 |
- |
H401 | P273 P501 |
It was classified into Category 2 from 48 hours LC50=1.15mg/L of the crustacea (Daphnia magna) (EHC169 (1996)). [NOTE]Since it may show same behavior of sodium salt in the environment, it was classified by the data of sodium undecylbenzenesulfonate(C11). |
FY2006 | GHS Classification Manual (10 Feb, 2006) |
11 | Hazardous to the aquatic environment Long term (Chronic) | 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=2.51(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 undecylbebzenesulfonic acid sodium salt(C11). |
