log Kow/ log Pow

Key value for chemical safety assessment

Additional information

Styrene is a liquid substance, which is slightly soluble in water. The US EPA developed software (KOWWIN v1.67/ US EPA, EPI Suite v 4.00) allows better estimation of its partition coefficient n-octanol/water. The calculated value for partition coefficient n-octanol/water of styrene log Kow/ log Pow =2.90 is, therefore, considered for the purpose of Chemical safety Assessment for styrene.
