#Castor oil as a prepo skin#
Undecylenic acid, a castor oil derivative, is also FDA-approved for over-the-counter use on skin disorders or skin problems. Castor oil can also be used to induce childbirth, but doing so is sometimes recommended against because it can lead to complications for the childbirth process, including dehydration of the mother and other risks associated with any inducement of pregnancy, such as fetal distress from too strong contractions, increased risk of uterine rupture (especially in a scarred uterus), unintentional prematurity of the baby, and increased pain level for the mother. However, it is not a preferred treatment for constipation. The United States Food and Drug Administration (FDA) has categorized castor oil as "generally recognized as safe and effective" (GRASE) for over-the-counter use as a laxative. Cremophor EL) is also used in the foodstuff industries. In the food industry, castor oil (food grade) is used in food additives, flavorings, candy (i.e., chocolate), as a mold inhibitor, and in packaging.
Castor oil fatty acids Average composition of Castor seed oil / fatty acid chains Alternatively, some researchers are trying to genetically modify the castor plant to prevent the synthesis of ricin. These health issues, in addition to concerns about the toxic byproduct ( ricin) from castor oil production, have encouraged the quest for alternative, domestic sources for hydroxy fatty acids. India, Brazil and China are the major crop producers and the workers suffer harmful side effects from working with these plants. However, harvesting castor beans is not without risk, Īllergenic compounds found on the plant surface can cause permanent nerve damage, making the harvest of castor beans a human health risk. The castor seed contains ricin, a toxic protein removed by cold pressing and filtering. It is used in formulating lubricants, softeners, and dyeing assistants. It was the first synthetic detergent after ordinary Soap. This allows easy use for making bath oil products. It is made by adding sulfuric acid to pure castor oil. Sulfonated castor oil, also called Sulfonated (sulfated) castor oil, or Turkey Red Oil, is the only oil that completely disperses in water. As an example, in July 2007 Indian castor oil sold for about US$0.90 per kilogram (US$0.41 per pound) while US soybean, sunflower and canola oil sold for about US$0.30 per kilogram (US$0.14 per pound) Ĭastor 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. Compared to other seed oils which lack the hydroxyl group, castor oil demands a higher price. It is the hydroxyl group which makes castor oil and ricinoleic acid valuable as chemical feedstocks. This functional group causes ricinoleic acid (and castor oil) to be unusually polar, and also allows chemical derivatization that is not practical with most other seed oils. Ricinoleic acid, a monounsaturated, 18-carbon fatty acid, is unusual in that it has a hydroxyl functional group on the twelfth carbon. 4 Castor oil: Use as a means of intimidation in Fascist Italy.3.4 Uses in early aviation and aeromodelling.
