The EN 14214 is more rigorous for this parameter, and some microalgae-based biodiesels do not meet this specification as seen in Table 10.4 because most microalgae species show a high degree of unsaturation and long-chain fatty acid contents. Factors such as growing conditions and lipid extraction may affect the fatty acid profile and consequently the biodiesel properties ( Soares et al., 2014).

However, in another study ( Song et al., 2013), this microalgae-based biodiesel was according to the specification (4.5В mm 2В s в€’В 1). For the Brazilian standard, only Phaeodactylum tricornutum presents biodiesel with KV (2.9В mm 2В s в€’В 1) slightly lower than the minimum established ( Gangadhar et al., 2015). The biodiesel viscosity from oilseeds, animal fat, and microalgae are in accordance with the ASTM standard. As shown in Table 10.4, biodiesel presents greater viscosity than diesel due to a higher degree of unsaturation and by oxidation reactions that can modify the fatty acid composition during storage, transportation, and temperature change ( Knothe and Steidley, 2007). Kinematic viscosity (KV) is a physical property related to the chain length and degree of saturation thus, this criterion is associated with oxidation stability and IV.
