Castor oil is a vegetable oil obtained from the castor bean
(technically castor seed) that has an unusual structure and many

Ricinus communis (Euphorbiaceae). Sometimes called castor bean oil,
this plant is not a member of the bean family.
Castor oil is a colorless to very pale yellow liquid with mild or
no odor or taste. Its boiling point is **3 °C (**5 °F) and its
density is **1 kg/m3.
Industry uses yearly ******0 million pounds of castor oil and its
derivatives have applications in the manufacturing of soaps,
lubricants, hydraulic and brake fluids, paints, dyes, coatings,
inks, cold resistant plastics, waxes and polishes, nylon,
pharmaceuticals and perfumes.
Food and preservative[edit]In the food industry, castor oil (food
grade) is used in food additives, flavorings, candy (e.g.,
Polyglycerol polyricinoleate or PGPR in chocolate), as a mold
inhibitor, and in packaging. Polyoxyethylated castor oil (e.g.,
Kolliphor EL)is also used in the food industries.
In India, Pakistan, Nepal and Bangladesh, food grains are preserved
by applying castor oil. It stops rice, wheat, and pulses from
rotting. For example the legume Toor dal is commonly available
coated in oil for extended storage.
