| 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 viscousoil. It has a slight odor and a taste that is initially bland butafterwards 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 blandcharacteristic 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 alarge caruncle; the endosperm is fleshy and oily. The plant thrives in rich, well-drained, sandy or clay loam; it is grown in India andthe 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. |
| Occurrence | Castor is a perennial found in India and Africa. |
| Uses | antidiabetic |
| 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 | 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 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 ofRicinus communis Linne (Fam. Euphorbiaceae). No other substancesare 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 gutto yield ricinoleic acid, the active purging agent. Thishydrolysis requires bile, a fact that is sometimes overlookedwhen castor oil is given as a laxative before radiographyin biliary obstruction.The ricinoleic acid actson the ileum and colon to induce an increased fluid secretionand colonic contraction. |
| Essential oil composition | The oil is a mixture of triglycerides of which 75 to 90% is ricinoleic acid.* This mixture is hydrolyzedto release ricinoleic acid, which exerts a cathartic effect. The cake remaining after the extraction of the oil is the castor pomace. Thephytotoxins ricin and ricinine are found in the seed cake and oil. Ricin is a glycoproptein containing neutral A chain and acidic Bchain 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, andpharmaceutical formulations. In pharmaceutical formulations,castor oil is most commonly used in topical creams and ointmentsat concentrations of 5–12.5%. However, it is also used in oral tabletand capsule formulations, ophthalmic emulsions, and as a solvent inintramuscular injections. Therapeutically, castor oil has been administered orally for itslaxative action, but such use is now obsolete. |
| Clinical Use | Castor oil is a bland oil that is hydrolyzed in the gutto yield ricinoleic acid, the active purging agent. Thishydrolysis requires bile, a fact that is sometimes overlookedwhen castor oil is given as a laxative before radiographyin 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 generallyregarded as a relatively nontoxic and nonirritant material whenused as an excipient. Castor oil has been used therapeutically as a laxative and oraladministration of large quantities may cause nausea, vomiting,colic, and severe purgation. It should not be given when intestinalobstruction is present. Although widely used in topical preparations, includingophthalmic formulations, castor oil has been associated withsome reports of allergic contact dermatitis, mainly to cosmeticssuch as lipsticks. |
| storage | Castor oil is stable and does not turn rancid unless subjected toexcessive heat. On heating at 3008℃ for several hours, castor oilpolymerizes and becomes soluble in mineral oil. When cooled to08℃, 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. |
| Toxics Screening Level | The initial threshold screening level for castor oil is 50 μg/m3 based on an 8-hour averaging time. |
| 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). Included innonparenteral medicines licensed in the UK. Included in theCanadian List of Acceptable Non-medicinal Ingredients. |
