[Rationale for the Classification] Based on (1), this substance is considered to be at least irritating. However, it was classified in Category 1 because alkyl aluminum is known to be corrosive based on (2) and (3). [Evidence Data] (1) There is a report that this substance is irritating to human skin (HSDB (2009)). (2) There is a report that contact with alkyl aluminum causes burns (HSDB (2009)). [Reference Data, etc.] (3) This substance was classified as "Skin Corr. 1B" by EU CLP (as alkyl aluminum). |
3 | Serious eye damage/eye irritation | Category 2 |
Warning |
H319 |
P305+P351+P338
P337+P313 P264 P280 |
[Rationale for the Classification] Although the details of (1) are unknown, it was classified in Category 2 based on the weight of evidence. Besides, the category was changed from the previous classification by reviewing the description from an information source. [Evidence Data] (1) There is a description that this substance is irritating to human eyes (HSDB (Accessed Aug. 2018)). |
4 | Respiratory sensitization | Classification not possible |
- |
- | - |
[Rationale for the Classification] Classification not possible due to lack of data. |
4 | Skin sensitization | Classification not possible |
- |
- | - |
[Rationale for the Classification] Although information (1) indicating that this substance is not a skin sensitizer was obtained, sufficient evidence to classify as "Not classified" was not obtained. Therefore, it was classified as "Classification not possible." [Reference Data, etc.] (1) There is a report that in an LLNA test (OECD TG442B, n=5 animals (control group)/10 animals (application group), GLP-compliant) with mice, no skin sensitization was observed after the application of this substance (REACH registration dossier (Accessed Aug. 2018)). |

6 | Carcinogenicity | Classification not possible |

[Rationale for the Classification] Classification not possible due to lack of data. |
7 | Reproductive toxicity | Classification not possible |
- |
- | - |
[Rationale for the Classification] Classification not possible due to lack of data. [Reference Data, etc.] (1) There is a concern that this substance may be taken into the body and cause hazard as aluminum. However, there is no knowledge that reproductive effects through oral intake of aluminum should be used for the rationale for classification (Risk Assessment Report (Food additives) (Food Safety Commission of Japan, 2017)). |
8 | Specific target organ toxicity - Single exposure | Category 3 (Respiratory tract irritation) |
Warning |
H335 |
P304+P340
P403+P233 P261 P271 P312 P405 P501 |
[Rationale for the Classification] Based on (1), it was classified in Category 3 (respiratory tract irritation). Besides, the classification result was changed from the previous one. [Evidence Data] (1) There is a report that this substance is irritating to human respiratory organs (HSDB (Accessed Aug. 2018)). |
9 | Specific target organ toxicity - Repeated exposure | Classification not possible |
- |
- | - |
[Rationale for the Classification] Classification not possible due to lack of data. [Reference Data, etc.] (1) There is a description that the exposure limit (TLV-TWA) of 1 mg/m3 was set for aluminum metal and insoluble aluminum compounds, similar compounds of this substance to protect against potential adverse effects on the lungs and nervous system observed in humans and experimental animals. On the other hand, there is a description that since there is a paucity of toxicity information for alkyl aluminum compounds, the TLV-TWA value should not be applied to them (ACGIH (7th, 2008)). |
