Vegetable oils have been widely studied as biofuel candidates. Among these oils, jojoba (
Simmondsia chinensis
) oil has attracted interest because it is composed almost entirely of wax esters that are liquid at room temperature. Consequently, it is widely used in the cosmetic and pharmaceutical industries. To date, research on
S. chinensis
oil has focused on to its use as a fuel and its thermal stability, and information about its thermal properties is scarce. In the present study, the thermal effusivity and conductivity of jojoba oil between
20
∘
C
and
45

C
were obtained using the inverse photopyroelectric and hot-ball techniques. The feasibility of an inverse photopyroelectric method and a hot-ball technique to monitor the thermal conductivity, and the thermal effusivity of the
S. chinensis
is demonstrated. The thermal effusivity decreased from 538
