There are various substitutes for isostearic acids (such as lauric acid, myristic acid, palmitic acid, stearic acid, ricinoleic
acid, oleic acid, behenic acid, erucic acid, and coconut fatty acid), which are readily available in the market at lower prices.
6) Castor oil is not used as a food source and it is chiefly composed of triglycerides of ricinoleic
acid, with minor contributions from oleic, linoleic, and others.
The pharmacologically active molecule in the oil is ricinoleic
acid, which is approximately 90% of the entire fatty acid chain composition.
In literature, castor oil (CO) was suggested as a polyol component for decreasing swelling degree of polymer due to its high content of ricinoleic
acid, which has a hydroxyl functional group on the 12th carbon [8, 9], The United States Food and Drug Administration has categorized CO as "generally recognized as safe and effective.
For nylon, the fatty acid molecule of interest is sebacic acid; for the polyol it is ricinoleic
Its 90-percent ricinoleic
acid content imparts characteristics that help make castor oil ideal for biodiesel.
The major fatty acid component of castor oil is ricinoleic
acid, which comprises 90% of the fatty acid profile.

acid", FEMS microbiology letters 209, pp.
It is the only NOP today that is produced directly from a plant source and that has a consistent chemical composition (90% ricinoleic
Alkyd paints are based on alkyd resin precursors, which are polyesters incorporating unsaturated fatty acid chains such as oleic acid, linoleic acid, linolenic acid, and ricinoleic
However, castor oil, which is converted to ricinoleic
acid in the gut, is an irritant that may induce premature labor.
Triacylglycerides of ricinoleic
and lesquerellic acid both contain three hydroxyl functional groups, and are therefore referred to as triols.
