and summary Crystallographic analysis of hydrogenated jojoba wax ester shows the crystal structure to be monoclinic with orthorhombic perpendicular, 0⊥, chain packing. Cell dimensions are: a=4.99, b=7.44, c=55.2Å, β=90°. A larger secondary unit cell is observed and identified as permitting the hydrocarbon ester chains freedom of rotation. Hydrogenated jojoba was ester is crystallographically similar to polyethylene.
