-
- - Classification not possible due to lack of data.
1 Acute toxicity (Inhalation: Gases) Not applicable
-
-
- - Liquid (GHS definition)
1 Acute toxicity (Inhalation: Vapours) Classification not possible
-
-
- - Classification not possible due to lack of data.
1 Acute toxicity (Inhalation: Dusts and mists) Classification not possible

-
- - Classification not possible due to lack of data.
2 Skin corrosion/irritation Classification not possible
-
-
- - Classification not possible due to lack of data.
3 Serious eye damage/eye irritation Classification not possible
-
-
- - Classification not possible due to lack of data.
4 Respiratory sensitization Classification not possible
-
-
- - Classification not possible due to lack of data.
4 Skin sensitization Classification not possible
-
-
- - Classification not possible due to lack of data.
5 Germ cell mutagenicity Classification not possible
-
-
- - Classification not possible due to lack of data. Besides, this substance is the reaction product of tetraethyl silicate (synonym: tetraethoxysilane (CAS RN 78-10-4)) and dibutyltin di (acetate) (CAS RN 1067-33-0). Tetraethyl silicate was classified as "Classification not possible" due to lack of data in the classification of FY2014, and dibutyltin di (acetate) was classified as "Classification not possible" due to lack of data in the classification of FY2016.
6 Carcinogenicity Classification not possible
-
-
- - Classification not possible due to lack of data. Besides, this substance is the reaction product of tetraethyl silicate (synonym: tetraethoxysilane (CAS RN 78-10-4)) and dibutyltin di (acetate) (CAS RN 1067-33-0). Tetraethyl silicate was classified as "Classification not possible" due to lack of data in the classification of FY2014, and dibutyltin di (acetate) was classified as "Classification not possible" based on classification results by other organizations in the classification of FY2016.
7 Reproductive toxicity Classification not possible
-
-
- - Classification not possible due to lack of data. Besides, this substance is the reaction product of tetraethyl silicate (synonym: tetraethoxysilane (CAS RN 78-10-4)) and dibutyltin di(acetate) (CAS RN 1067-33-0). Tetraethyl silicate was classified as "Classification not possible" due to lack of data in the classification of FY2014. On the other hand, dibutyltin di (acetate) was classified in Category 1B in the classification of FY 2016 because teratogenicity was observed at doses where no general toxicity effect was observed in maternal animals.
8 Specific target organ toxicity - Single exposure Classification not possible
-
-
- - Classification not possible due to lack of data. There is no information on a single exposure to this substance in humans and experimental animals.
Besides, this substance is the reaction product of tetraethyl silicate (synonym: tetraethoxysilane (CAS RN 78-10-4)) and dibutyltin di (acetate) (CAS RN 1067-33-0). As for tetraethyl silicate, there are reports of central nervous system depression, anemia and respiratory tract irritation in humans and experimental animals, and it was classified in Category 1 (haemal system), Category 3 (respiratory tract irritation, narcotic effects) in the classification of 2014. Dibutyltin di(acetate) was classified as "Classification not possible" due to lack of data in the classification of FY2016.
9 Specific target organ toxicity - Repeated exposure Classification not possible
-
-
- - Classification not possible due to lack of data.
Besides, this substance is the reaction product of tetraethyl silicate (synonym: tetraethoxysilane (CAS RN 78-10-4)) and dibutyltin di (acetate) (CAS RN 1067-33-0). As for tetraethyl silicate, in experimental animals, renal tubule degeneration/necrotic nephrosis, via the oral route, and inflammation of the nasal mucosa, and inflammation of the renal tubules and interstitium, via the inhalation route, were observed, and it was classified in Category 1 (respiratory organs), Category 2 (kidney) in the classification of FY 2014.
As for dibutyltin di (acetate), in experimental animals, degeneration/necrotic changes in the liver were observed, via the oral route, and it was classified in Category 2 (liver) in the classification of FY 2016.
