We report the values of some thermal and electrical properties of Candelilla Wax (euphorbia cerifera). The open-cell photoacoustic technique and another photothermic technique - based on the measure of the temperature decay of a heated sample - were employed to obtain the thermal diffusivity (αs = 0.026 ± 0.00095 cm2/sec) as well as the thermal conductivity (k=2.132 ± 0.16 W/mK) of this wax. The Kelvin null method was used to measure the dark decay of the surface potential of the sample after a Corona Discharge, obtaining a resistivity of ρe=5.98 ± 0.19 × 1017 ohm-cm.
