COTTONSEED OIL Usage And Synthesis
pale yellow liquid
Pale yellow or bright golden yellow-colored, clear oily liquid. It is odorless, or nearly so, with a bland, nutty taste. At temperatures below 10°C particles of solid fat may separate from the oil, and at about–5 to 10°C the oil becomes solid or nearly so.If it solidifies,the oil should be remelted and thoroughly mixed before use.
Pharmaceutic aid (solvent).
Cottonseed oil is the refined fixed oil obtained from the seed of cultivated varieties of Gossypium hirsutum Linne or of other species of Gossypium (Fam. Malvaceae). The seeds contain about 15% oil. The testae of the seeds are first separated and the kernels are then exposed to powerful expression in a hydraulic press. The crude oil thus obtained has a bright red or blackish-red color and requires purification before it is suitable for food or pharmaceutical purposes.
Cottonseed oil is refined by treatment with diluted alkali to neutralize acids, decolorized with fuller’s earth or activated carbon, deodorized with steam under reduced pressure, and chilled to separate glycerides and resinous substances of higher melting point.
Odorless colorless to pale-yellow liquid. Less dense than water and insoluble in water. Hence floats on water. Freezing point 32°F. Contains principally the glycerides of palmitic, oleic and linoleic acids.
Air & Water Reactions
Insoluble in water.
COTTONSEED OIL is sensitive to heat and light.
None; is used as a food.
COTTONSEED OIL is combustible.
Cottonseed oil is used in pharmaceutical formulations primarily as a solvent for intramuscular injections. It has been used in intravenous emulsions as a fat source in parenteral nutrition regimens, although its use for this purpose has been superseded by soybean oil emulsions. It has also been used as an adjuvant in cholecystography and as a pediculicide and acaricide. It has the nutritive and emollient properties of fixed vegetable oils. By virtue of its high content of unsaturated acid glycerides (especially linoleic acid), it is used for dietary control of blood cholesterol levels in the prophylaxis and treatment of atherosclerosis. It is used as a solvent and vehicle for injections; as an emollient vehicle for other medications; and orally as a mild cathartic (in a dose of 30mL or more). It can also retard gastric secretion and motility, and increase caloric intake. It has been used in the manufacture of soaps, oleomargarine, lard substitutes, glycerin, lubricants, and cosmetics.
Cottonseed oil has been used as a tablet binder for acetaminophen; for characterization of the hot-melt fluid bed coating process;(1) in the manufacturing of stable oral pharmaceutical powders; in encapsulation of enzymes; and as an aqueous dispersion in pharmaceutical coating.
Questionable carcinogen with experimental tumorigenic data. Experimental teratogenic effects. An allergen. Combustible liquid when exposed to heat or flame. However, if allowed to impregnate rags or oily waste, it can become a dangerous hazard due to spontaneous heating. To fight fire, use COa, dry chemical.
Cottonseed oil emulsions have in the past been used in long-term intravenous nutrition regimens. A complex of adverse reactions,called the ‘overloading syndrome’has been seen with chronic administration of cottonseed oil emulsion. This consisted of anorexia,nausea,abdominal pain,headache,fever,and sorethroat. Signs of impaired liver function, anemia, hepatosplenomegaly, thrombocytopenia, and spontaneous hemorrhage due to delayed blood clotting have been reported. For parenteral nutrition purposes, cottonseed oil has been replaced by soybean oil,especially in pregnant women, where the use of cottonseed lipid emulsion has been associated with adverse effects.
A notable difference between the cottonseed oil emulsion and the soybean oil emulsion is the particle size.The cottonseed oil emulsion has much larger particles than the soybean oil emulsion. These larger particles may have been handled differently by the body, thus perhaps accounting for some of the toxic reactions.
Cottonseed oil is stable if stored in a well-filled, airtight, lightresistant container in a cool, dry place. Avoid exposure to excessive heat.
