Endpoint:

adsorption / desorption: screening

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the substance has a low octanol water partition coefficient and the adsorption potential of this substance is related to this parameter

Justification for type of information:

JUSTIFICATION FOR DATA WAIVING
According to the column 2 of REACH Annex VIII, the study does not need to be conducted since the substance is expected to have low potential for adsorption based on the low octanol-water partition coefficient (log Kow < 3).

Reason / purpose for cross-reference:

data waiving: supporting information

Description of key information

Data waiving (study scientifically not necessary): According to the column 2 of REACH Annex VIII, the study does not need to be conducted since the substance is expected to have low potential for adsorption based on the low octanol-water partition coefficient (log Kow < 3).

Supporting study: KOCWIN v2.00, MCI method. Soil adsorption of triacetoxyvinylsilane was estimated to be: Koc = 10 L/kg and Log Koc = 1.

Key value for chemical safety assessment

Koc at 20 °C:

10

Additional information

Data waiving (study scientifically not necessary): According to the column 2 of REACH Annex VIII, the study does not need to be conducted since the substance is expected to have low potential for adsorption based on the low octanol-water partition coefficient (log Kow < 3).

Supporting study: Soil adsorption for triacetoxyvinylsilane was estimated by KOCWIN v2.00, MCI method and was determined to be: Koc = 10 L/kg and Log Koc = 1.
