Some extraction techniques bring a lot of water-soluble contaminants into the crude extract. Among the contaminants are sugars, phospholipids, and pigments. Liquid-liquid extraction using water on the crude extract can remove these contaminants from oil into the water. Water extracted oil has better visual appeal, higher purity, and improved post-extraction processing of cannabinoids.

These water-soluble compounds can cause charring and fouling in the distillation apparatus. Continuously operated equipment must be broken down to handle the buildup of these residues. Many of these more polar compounds cannot be separated by distillation either.
