Composition of several coccid waxes has been determined by means of alumina and gas‐liquid chromatography.Coccus ceriferus wax is a mixture of the esters of C26 and C28 alcohols with C24, C26 and C28 acids.Tachardia lacca wax has a high percentage of free alcohols (essentially C28 alcohol);Gascardia madagascariensis wax contains a large proportion of free acids. In addition to C26, C32 and C34 normal chain acids, there are several C30, C32 and C34 hydroxy acids, in which the hydroxyl function is situated in the middle of the hydrocarbon chain. Small proportions of odd and even hydrocarbons are present in all of the waxes investigated.
