Castor Oil

Castor oil is the preferred lubricant for , most likely because it doesn't dissolve natural-rubber seals.

Castor oil is the raw material for the production of a number of chemicals, notably , , -11. A review listing numerous chemicals derived from castor oil is available.

Since it is has a relatively high (4.7), highly refined and dried castor oil is sometimes used as a dielectric fluid within high performance high voltage .

Vegetable oils, due to their good and are attractive alternatives to -derived , but stability and low temperature performance limit their widespread use. Castor oil has better low temperature properties and high temperature lubrication than most vegetable oils, making it useful as a lubricant in , , and race-car engines. However, castor oil tends to form gums in a short time, and its use is therefore restricted to engines that are regularly rebuilt, such as race engines. Biodegradability results in decreased persistence in the environment (relative to petroleum-based lubricants) in case of an accidental release. The lubricants company took its name from castor oil.

[] Industrial castor oil

Castor oil has numerous applications in transportation, cosmetics and pharmaceutical, and manufacturing industries, for example: , , caulks, , electrical liquid dielectrics, , hydraulic fluids, , lacquers, treatments, lubricating greases, machining oils, , pigments, adhesives , refrigeration lubricants, , sealants, , washing powders, and waxes.

Castor oil has been used to induce in pregnant women, though it is not always effective in application. Castor oil, when ingested, triggers cramping in the bowel (making it an effective ). Thus, it is intended that such cramping extend to the uterus. In an overdue pregnancy in which the mother's cervix is already effacing and partially dilated, this cramping can lead to labor contractions. The irregular, painful contractions of castor-oil-induced labor can be stressful on the mother and fetus.^[] It also leaves the laboring woman quite dehydrated as a result of the vomiting and diarrhea which result when the recommended dose of castor oil for labor induction is taken2 , or about 8 . This leaves her without access to the energy she could otherwise derive from food or drink throughout her labor process. Using castor oil for induction is not recommended without consulting a medical practitioner and is not recommended in a complex pregnancy.^[]

[] Traditional or folk medicines

The use of cold pressed castor oil in folk medicine predates government medical regulations. Cold pressed castor oil is tasteless and odorless when pure. Uses include skin problems, burns, sunburns, skin disorders, skin cuts, and abrasions. Castor oil has also been used to draw out in the eye by pouring a small amount into the eye and allowing it to circulate around the inside of the eyelid. Note that most bottles of castor oil indicate the oil is to be kept away from the eyes. The oil is also used as a rub or pack for various ailments, including abdominal complaints, headaches, muscle pains, inflammatory conditions, skin eruptions, lesions, and sinusitis. A castor oil pack is made by soaking a piece of flannel in castor oil, then putting it on the area of complaint and placing a heat source, such as a hot water bottle, on top of it. This remedy was often suggested by the American , given in many healing readings in the early mid-1900s. Castor oil has also been noted for its acne-healing abilities.

Therapeutically, modern drugs are rarely given in a pure chemical state, so most active ingredients are combined with excipients or additives. Castor oil, or a castor oil derivative such as (polyethoxylated castor oil, a nonionic ), is added to many modern drugs, including:

One study has found that castor oil decreased pain more than ultrasound gel or Vaseline during application.

is the main component of castor oil and it exerts anti-inflammatory effects.

Castor oil penetrates deep into the skin thanks to its , which is low enough to penetrate into the stratum corneum. Castor Isostearate Succinate is a mixture of with and used for , such as in , and .

[] Medicinal use of castor oil

The United States (FDA) has categorized castor oil as "" (GRASE) for over-the-counter use as a , with its major site of action the . However, although it may be used for constipation, it is not a preferred treatment. , a castor oil derivative, is also FDA-approved for over-the-counter use on skin disorders or skin problems.

In the food industry, castor oil (food grade) is used in food additives, flavorings, candy (e.g., chocolate), as a mould inhibitor, and in packaging. Polyoxyethylated castor oil (e.g., ) is also used in the foodstuff industries.

Castor oil in food

Castor Oil, FSG, Hydrogenated castor oil (HCO) or castor wax, Hydroxy Stearic Acids or 12-HAS .Ricinoleic acid, a , 18-carbon , is unusual in that it has a on the twelfth carbon. This functional group causes ricinoleic acid (and castor oil) to be unusually , and also allows chemical that is not practical with most other seed oils. It is the hydroxyl group which makes castor oil and ricinoleic acid valuable as chemical feedstocks. Compared to other seed oils which lack the hydroxyl group, castor oil commands a higher price.

Castor Oil is extracted from High quality Castor seeds,It has medicinal use.
