plant waxes to precipitate out of solution, so they can be removed by filtration, to turn a raw oleoresin extract into an&nbsp;<strong>Absolute<\/strong>.<\/p>\n\n\n\n<p>The non polar plant waxes are marginally suspended in the polar alcohol and when the temperature goes down and the ability of the alcohol to hold solute in solution, the first thing to drop out is the non polars.&nbsp; In point of fact, the waxes would precipitate out of solution all by themselves at ambient temperatures if given enough time.<\/p>\n\n\n\n<p>Here is a jar of BHO dissolved in ethanol, which simply sat on the
