巴西棕榈蜡的水解产物，以前被证明主要由直链醇，α，ω-二醇，烷酸和ω-羟基烷酸组成，通过气相色谱方法重新检查，以提供成分的定性和定量知识。这些成分，显示出几乎完全是直链的性质，大部分是偶数碳数的化合物，但也存在奇数链长。碳氢化合物同样是奇数和偶数碳数，奇数成员占主导地位（90%）。一种未知的化合物，可能是不饱和类固醇二醇，已经从不皂化的部分中分离出来。
The hydrolytic products of carnauba wax, previously shown to consist mainly of straight-chain alcohols, α,ω-diols, alkanoic acids, and ω-hydroxyalkanoic acids, have been reexamined by gas chromatographic methods to provide a qualitative and quantitative knowledge of the components. These components, shown to be almost entirely straight chain in character, are largely even carbon numbered compounds, but odd chain-lengths are present. The hydrocarbons are likewise of odd and even carbon number with the odd members (90%) predominating. An unidentified compound, possibly an unsaturated steroid diol, has been isolated from the unsaponifiable fraction.
