Castor oil is a vegetable oil pressed from castor beans. It is a colourless or pale yellow liquid with a distinct taste and odor. Its boiling point is 313 °C (595 °F) and its density is 0.961 g/cm3. It includes a mixture of triglycerides in which about 90% of fatty acids are ricinoleates.

castor beans Wakefield researchers found that adding a measure of castor oil, a vegetable oil made from castor beans, did the trick nicely. They called the new product “Castrol.” In 1919 John Alcock and Arthur Brown choose Castrol to lubricate their engine on the first trans-Atlantic flight.

castor beans It's made by extracting oil from the seeds of the Ricinus communis plant. These seeds, which are known as castor beans, contain a toxic enzyme called ricin. However, the heating process that castor oil undergoes during production deactivates the ricin, allowing the oil to be used safely.

England On 19th March 1899, Charles 'Cheers' Wakefield set up an oil company in England. Ten years later, he produced a new lubricant that would revolutionise transport in the first half of the twentieth century. He called the new oil Castrol.

Castor oil benefits for skin Because it's rich in fatty acids, castor oil has moisturizing effects. You can find it in many commercial beauty products. You can also use it in its natural form, which is free of perfumes and dyes. Because it can be irritating to skin, try diluting it with another neutral oil.

Castor oil is well known as a source of ricinoleic acid, a monounsaturated, 18-carbon fatty acid. Among fatty acids, ricinoleic acid is unusual in that it has a hydroxyl functional group on the 12th carbon atom. This functional group causes ricinoleic acid (and castor oil) to be more polar than most fats.
