Additional information

The partition coefficient n-octanol/water of Sodium ethylparaben was determined by the shake flask method in a study according to OECD Guideline No. 107 to be log P(OW) = -0.14.

The partition coefficient n-octanol/water of Ethylparaben (the corresponding acid at neutral pH) was determined by the shake flask method similar to OECD Guideline No. 107 to be log P(OW) = 2.44.
