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. | [NIST Chemistry Reference]

| Hazard Information | Back Directory | [Chemical Properties]
pale yellow viscous liquid | [Uses]
antidiabetic | [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. | [Health Hazard]
If ingested causes severe diarrhea. | [Fire Hazard]
Castor oil is combustible. | [Hazard]
Undergoes spontaneous heating.
| [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. | [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. | [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. | [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. | [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]
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]
