A generalized method was developed to estimate the liquid density of vegeta
ble oils and fatty acids. The correlation for vegetable oils was based on f
atty acid critical properties and composition of the oil. The correlations
predicted the density of vegetable oils and fatty acids with an average abs
olute deviation of 0.21 and 0.77%, respectively. The present method is slig
htly more accurate in predicting vegetable oil density and simpler than the
method of Halvorsen et al. Also, a method is introduced that predicts visc
osity from density data, thus relating two key properties of vegetable oils
