Bladderpod oil
Open-knowledge reference entry

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. 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. 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. The fatty acid composition of bladderpod oil is:
Other species of bladderpod that yield similar oils include Physaria 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.
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.
This brief starts where responsible research should: with the source description of “Bladderpod oil” as open-knowledge reference entry. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as open-knowledge reference entry. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated May 1, 2026. The linked authority identifier is Q4923671. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
