Additional information

Penta-1,3-diene 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 itspartition coefficient n-octanol/water. The calculated value for partition coefficient n-octanol/water ofpenta-1,3-dienelog Kow/ log Pow =2.44 is, therefore, adopted for the purpose of this CSR.
