Castor oil Usage And Synthesis
Chemical Properties pale yellow viscous liquid
Chemical Properties Dehydrated castor oil is a castor oil from which approximately 5% of the chemically combined water has been removed. Therefore it has drying properties similar to those of Tung oil. Dehydration is carried out by heating the oil in the presence of catalysts such as sulphuric acid, phosphoric acid, clays and metal oxides. Dehydrated castor oil is a yellow oily liquid with characteristic odour.

Chemical Properties Castor oil is a clear, almost colorless or pale yellow-colored viscous oil. It has a slight odor and a taste that is initially bland but afterwards slightly acrid.
Chemical Properties Castor oil is obtained by cold expression of kernels, which contain 45 to 50% oil. It has a faint, mild odor and a bland characteristic taste.
Chemical Properties Castor tree is a common annual ornamental whose native habitat is in the West Indies. The tree grows up to 5 m high. The leaves are large, alternate, peltate, palmately 5- to 12-lobed; the petiolate has conspicuous glands. The seeds are ovoid with a large caruncle; the endosperm is fleshy and oily. The plant thrives in rich, well-drained, sandy or clay loam; it is grown in India and the United States. Castor beans have been cultivated from the earliest times for the oil of the seeds, the only part used. Commercially, the oils and cakes are obtained by cold expression or are steam treated to denature the toxin.
Physical properties The oil is a pale-yellowish or almost colorless, transparent viscid liquid. It is soluble in alcohol, and is miscible with absolute alcohol, glacial acetic acid, chloroform and ether.
Uses Dehydrated castor oil is an unique drying oil, which imparts good flexibility, fine gloss, toughness, adhesion, chemical and water resistance to the dry paint film with non-yellowing properties. DCO is a very suitable and even better substitute for Linseed oil. Paints with DCO are super white and offer superior finish.
Dehydrated castor oil is used as a primary binder for house paints, enamels, caulks, sealants and inks. In “cooked” varnishes it is combined with all the basic resins, rosins, rosin-esters, hydrocarbons and phenolics to produce clear varnishes and vehicles for pigmented coatings. DCO is also used in the manufacturing of lithographic inks, linoleum, putty and phenolic resins.
DCO is used with phenolics to obtain fast drying coatings with maximum alkali resistance as required in sanitary can lining, corrosion resistant coatings, traffic paints, varnishes, ink vehicles, wire enamels, aluminium paint appliance finishes and marine finishes.
DCO is also used to obtain fast kettling rate which gives lighter colour and lower acid varnishes.
Uses Castor Oil is a release and antisticking agent used in hard candy pro- duction. its concentration is not to exceed 500 ppm. it is used in vitamin and mineral tablets, and as a component of protective coatings.
Uses antidiabetic
Uses castor oil is a highly emollient carrier oil that penetrates the skin easily, leaving it soft and supple. It also serves to bind the different ingredients of a cosmetic formulation together. Castor oil is high in glycerin esters of ricinoleic acid (an unsaturated fatty acid). It is rarely, if ever, associated with irritation of the skin or allergic reactions. It is obtained through cold-pressing from seeds or beans of the Ricinus communis (castor oil) plant. Impure castor oil may cause irritation, as the seeds contain a toxic substance that is eliminated during processing. Its unpleasant odor makes it difficult to use in cosmetics.
Uses PEG-30 castor oil, -30 castor oil (hydrogenated), -40 castor oil, -40 castor oil (hydrogenated) are emollients, detergents, emulsifiers, and oil-in-water solubilizers recommended for fragrance oils, and for other oils that may be difficult to solubilize. The -40 castor oil version is a powerful solubilizer for solubilizing essential oils and perfumes in oil-in-water creams and lotions. It is similar to Peg-30 castor oil but denser, being a soft paste rather than a liquid. The hydrogenated version is particularly used as a nonionic emulsifier for essential oils and perfumes.
Production Methods Castor oil is the fixed oil obtained by cold-expression of the seeds of Ricinus communis Linne (Fam. Euphorbiaceae). No other substances are added to the oil.
Definition castor oil: A pale-coloured oil extractedfrom the castor-oil plant. Itcontains a mixture of glyceridesof fatty acids, the predominantacid being ricinoleic acid,C17H32(OH)COOH. It is used as adrying oil in paints and varnishesand medically as a laxative.
Indications Castor oil is a bland oil that is hydrolyzed in the gut to yield ricinoleic acid, the active purging agent. This hydrolysis requires bile, a fact that is sometimes overlooked when castor oil is given as a laxative before radiography in biliary obstruction.The ricinoleic acid acts on the ileum and colon to induce an increased fluid secretion and colonic contraction.
Essential oil composition The oil is a mixture of triglycerides of which 75 to 90% is ricinoleic acid.* This mixture is hydrolyzed to release ricinoleic acid, which exerts a cathartic effect. The cake remaining after the extraction of the oil is the castor pomace. The phytotoxins ricin and ricinine are found in the seed cake and oil. Ricin is a glycoproptein containing neutral A chain and acidic B chain connected by disulfur bonds.
General Description Pale-yellow or almost colorless transparent viscous liquid with a faint mild odor and nauseating taste. Density 0.95 g / cm3. A mixture of glycerides, chiefly ricinolein (the glyceride of ricinoleic acid) .
Air & Water Reactions Insoluble in water.
Reactivity Profile Castor oil can develop heat spontaneously in the air. [Hawley]. Reacts with acids to liberate heat along with alcohols and acids. Heat is also generated by interaction with caustic solutions. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Flammable hydrogen is generated by mixing with alkali metals and hydrides.
Hazard Undergoes spontaneous heating.
Health Hazard If ingested causes severe diarrhea.
Fire Hazard Castor oil is combustible.
Pharmaceutical Applications Castor oil is widely used in cosmetics, food products, and pharmaceutical formulations. In pharmaceutical formulations, castor oil is most commonly used in topical creams and ointments at concentrations of 5–12.5%. However, it is also used in oral tablet and capsule formulations, ophthalmic emulsions, and as a solvent in intramuscular injections.
Therapeutically, castor oil has been administered orally for its laxative action, but such use is now obsolete.
Clinical Use Castor oil is a bland oil that is hydrolyzed in the gut to yield ricinoleic acid, the active purging agent. This hydrolysis requires bile, a fact that is sometimes overlooked when castor oil is given as a laxative before radiography in biliary obstruction.
Safety Profile An allergen. A human skin and eye irritant. Combustible when exposed to heat. Spontaneous heating may occur. To fight fire, use CO2, dry chemical, fog, mist. See also CASTOR BEAN.
Safety Castor oil is used in cosmetics and foods and orally, parenterally, and topically in pharmaceutical formulations. It is generally regarded as a relatively nontoxic and nonirritant material when used as an excipient.
Castor oil has been used therapeutically as a laxative and oral administration of large quantities may cause nausea, vomiting, colic, and severe purgation. It should not be given when intestinal obstruction is present.
Although widely used in topical preparations, including ophthalmic formulations, castor oil has been associated with some reports of allergic contact dermatitis, mainly to cosmetics such as lipsticks.
storage Castor oil is stable and does not turn rancid unless subjected to excessive heat. On heating at 3008℃ for several hours, castor oil polymerizes and becomes soluble in mineral oil. When cooled to 08℃, it becomes more viscous.
Castor oil should be stored at a temperature not exceeding 258℃ in well-filled airtight containers protected from light.
Incompatibilities Castor oil is incompatible with strong oxidizing agents.
Regulatory Status GRAS listed. Included in the FDA Inactive Ingredients Database (IM injections; ophthalmic emulsions; oral capsules and tablets; topical creams, emulsions, ointments, and solutions).
