"The saturated aqueous distillate prepared by distilling the fresh flowers of Citrus Aurantium amara Linne (Fam. Rutaceae) with water. Preserve it in bottles stoppered with a pledget of purified cotton and in a dark, cool place." U. S. The orange flower water of commerce is a saturated solution of the essential oil of the fresh flowers, and the British Pharmacopoeia uses this in several preparations, terming it "Orange-flower water of commerce, undiluted." (See Aqua Aurantii Florum)
Orange flower water is nearly colorless, though often of a pale yellowish tint. "Stronger Orange Flower Water is colorless and clear or only faintly opalescent, and possesses a strong and pleasant odor and taste of orange blossoms, and must be free from empyreuma, mustiness, or mucoid growths. It is neutral or only slightly acid to litmus, and 100 mils, when evaporated to dryness on a water bath and the residue subsequently dried in an oven to constant weight at 100° C. (212° F.), yields not more than 0.001 Gm. of residue. It gives no reaction with hydrogen sulphide T.S. or with sodium sulphide T.S. (metallic impurities)." U. S. From being kept in tinned copper cans, it sometimes contains metallic impurity, which is said to be chiefly lead carbonate, derived from the lead used as a solder in making the cans. The means of detecting metallic impurity is also mentioned under the general observations on distilled water. Much color, offensive odor, or mouldiness indicates impurity derived from the flowers in distillation.
