Spermaceti (from Greek sperma, seed, and Latin cetus, whale) sometimes erroneously called parmaceti is a wax present in the head cavities of the sperm whale (Physeter macrocephalus). Spermaceti is extracted from sperm oil by crystallisation at 6 °C, when treated by pressure and a chemical solution of caustic alkali. Spermaceti forms brilliant white crystals that are hard but oily to the touch, and are devoid of taste or smell, making it very useful as an ingredient in cosmetics, leatherworking, and lubricants. The substance was also used in making candles of a standard photometric value, in the dressing of fabrics, and as a pharmaceutical excipient, especially in cerates and ointments.
