The speed of sound in spermaceti is 2,684 m/s (at 40 kHz, 36 °C), making it nearly twice as goo… Spermaceti. Spermaceti, a wax, liquid at body temperature, obtained from the head of a sperm whale or bottlenose whale.Spermaceti was used chiefly in ointments, cosmetic creams, fine wax candles, pomades, and textile finishing; later it was used for industrial lubricants. Spermaceti is the term given to the liquid waxes present in the head of the sperm whale (Physeter macrocephalus).The word comes from the late Latin sperma, “sperm” or “semen,” and the classical Latin ceti, genitive singular of cetus, “sea monster” or “whale”—literally “semen of whale.”It was bestowed because of the superficial resemblance of these waxes to semen. Cetyl alcohol was discovered in 1817 by the French chemist Michel Chevreul.When he heated a sample of spermaceti (a solid wax formed by the cooling of sperm whale oil) with caustic potash (potassium hydroxide), colourless crystals appeared. Benzoated Lard. © 2020 Spectrum Chemical Manufacturing Corp. All rights reserved. Camphor Gum. Insoluble in water, and nearly so in cold alcohol; soluble in boiling alcohol; also in ether, chloroform, carbon disulphide, fixed and volatile oils; only slightly soluble in cold benzin. The oil is then drained off as much as possible, and the remainder is removed from the spermaceti by powerful pressure. There are different subtypes of beeswaxes ... Spermaceti 45-49 0.94-0.95 1 116-125 16 . It is then termed cetin (cetyl palmitate) (C16H33.C16H31O2), and is soluble in 40 parts of boiling alcohol of specific gravity 0.821. Spermaceti is found in various parts of its body, in small proportions, dissolved in its blubber, but that which is met with in commerce is obtained from large cavities in the upper part of the head; these are divided into numerous cells, which are filled with a milky, oleaginous solution of spermaceti. It also contains 50-63 percent of wax alcohols. It is freely soluble in boiling alcohol, which deposits it on cooling; also in fused fats or resins. Introduction. At the same time it is hard to accept the sugges­ tion of one worker that such focusing can concentrate sound intensely enough By this method, or when it is deprived of oil by means of an alkali, it becomes a nearly pure proximate principle, intermediate between wax and the concrete oils, and presenting all the leading properties of the ordinary article, but less unctuous, rather harder, and fusible only at 49° C. (120.2° F.). The NF grade indicates it. The crude spermaceti is subsequently purified by fusing and skimming it, then fusing it in weak lye of potassa, and finally by a third fusion at a gentle heat; after which it is solidified in tin molds. Spermaceti wax is found in the head cavities and blubber of the sperm whale. Cinnamon also contains tannin and mucilage The quantity and chemical composition of essential oil from flowers of jasmine (Jasminum multiflorum L.) harvested in the morning (8.00 a.m.) and evening (6.00 p.m.) were compared. The oils of sperm whales and the other toothed whales differ in composition from those of the baleen whales. The former official unit of illumination, the candlepower, was defined as the light given off by a candle of pure spermaceti burning … Spermaceti wax is found in the head cavities and blubber of the sperm whale. Jojoba oil is a Besides cetin, stearic, lauro-stearic, and myristic acids, as well as other and higher alcohols, besides ethal, are present in spermaceti. 3. Spermaceti was used in medicine in England (15th century) and later in cosmetics, pharmacy, and also in candles. The prostate gland contributes about 30 percent of the seminal fluid; the constituents of its secretions are mainly citric acid, acid phosphatase, calcium, sodium, zinc, potassium, protein -splitting enzymes, and fibrolysin (an enzyme that reduces blood and tissue fibres). Although Chevreul thought that these crystals were a compound of ethylene and water, a more complete analysis by other researchers in 1836 established … The substance was named in the mistaken belief that it was the coagulated semen of the whale. Chemically, pure spermaceti consists principally of cetyl palmitate and other esters of fatty acids with fatty alcohols and melts at about 44 °C (111 °F). My Favorites List The blubber oil of the whale is about 66% wax. If to spermaceti be added half its weight of olive oil, and after mixing this, powdered gum Arabic be added, and, finally, some water be added by degrees, an emulsion may be formed, useful for children and infants. Action, Medical Uses, and Dosage.—Demulcent and protective, combined with equal parts of loaf-sugar, once used among children in domestic practice in coughs, colds, and catarrhal affections, and in irritation of the intestinal mucous membranes. The oils of sperm whales and the other toothed whales differ in composition from those of the baleen whales. Cetyl alcohol, also called 1-hexadecanol, [CH 3 (CH 2) 15 OH], a solid organic compound that was one of the first alcohols to be isolated from fats. Introduction. It melts near 50° C. (122° F.), and congeals near 45° C. (113° F.). Brain to sperm whales as raw materials, first pressure filter to remove stearic acid esters, and then a small amount of sodium hydroxide and water azeotrope and then washing water generated from. Spermaceti remained the primary candle wax until the mid-1800s, when stearin wax and then paraffin wax were developed. The seeds contain about 18 per cent of fixed oil, 38 per cent of proteins and an enzyme, urease. It becomes yellowish and rancid by exposure to the air. Those of the baleen whales consist exclusively of triglycerides. plant is distinct in its chemical properties to the WEs found in spermaceti oil (Miwa, 1971).
