Castor oil is a vegetable oil pressed from castor beans, the seeds of the plant Ricinus communis. [1] The seeds are 40 to 60 percent oil. [ 2 ] It is a colourless or pale yellow liquid with a distinct taste and odor.
Undecylenic acid is an organic compound with the formula CH 2 =CH(CH 2) 8 CO 2 H. It is an unsaturated fatty acid.It is a colorless oil. Undecylenic acid is mainly used for the production of Nylon-11 and in the treatment of fungal infections of the skin, but it is also a precursor in the manufacture of many pharmaceuticals, personal hygiene products, cosmetics, and perfumes.

ACS grade is the highest level of purity, and meets the standards set by the American Chemical Society (ACS). The official descriptions of the ACS levels of purity is documented in the Reagent Chemicals publication, issued by the ACS. [3] [4] It is suitable for food and laboratory uses. Reagent grade is almost as stringent as the ACS grade.
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
Ricinoleic acid, formally called 12-hydroxy-9-cis-octadecenoic acid, is a fatty acid.It is an unsaturated omega-9 fatty acid [1] and a hydroxy acid.It is a major component of the seed oil obtained from the seeds of castor plant (Ricinus communis L., Euphorbiaceae), the plant that produces ricin.
Castor oil by itself has been used in making a variety of polyurethane products, ranging from coatings to foams, and the use of castor oil derivatives continues to be an area of active development. Castor oil derivatized with propylene oxide [9] makes polyurethane foam for mattresses and yet another new derivative is used in coatings [10]

Castor oil and epichlorohydrin are reacted in the presence of a Lewis acid catalyst to form halohydrin: each hydroxyl group of the triol reacts with an epoxide on epichlorohydrin. This process is followed neutralizing the catalyst with a small amount of sodium hydroxide and then adding a large excess of epichlorohydrin as solvent.
