Bladderpod oil

Last updated

Bladderpod oil is a seed oil, extracted from the seeds of the Physaria fendleri and other species of genus Physaria , Native to the plains and mesas of southwestern United States, eastward to Kansas and southward into northern Mexico. [1] Bladderpod oil is rich in lesquerolic acid (C20:1-OH), a rare hydroxycarboxylic acid. The only commercial source of hydroxycarboxylic acids is ricinoleic acid (C18:1-OH), found in castor oil. [2] Essentially all castor oil production in the U.S. has been eliminated by a combination of economic factors, excessive allergenic reactions of field and processing workers, and toxicity of the seed meal. [3] The fatty acid composition of bladderpod oil is:

Fatty acid Percentage
Palmitic 1.5%
Palmitoleic 1.4%
Stearic 2.4%
Oleic 15.2%
Linoleic 7.6%
Linolenic 13.1%
Ricinoleic 0.3%
Densipolic 0.2%
Lesquerolic 53.2%
Auricolic 3.8%

Other species of bladderpod that yield similar oils include Physaira lindheimeri , Paysonia densipilia , Paysonia auriculata and Physaria pallida . P. fendleri is of particular interest because of the yields of 1,500 kg/ha that have been achieved in only a few years of cultivation. [2]

Uses

The hydroxycarboxylic acids contained in bladderpod oil are an important raw material used in the manufacture of resins, waxes, nylons, plastics, corrosion inhibitors, coatings, lubricating greases and cosmetics. [3]
