Poligeenan
type of polymer

Poligeenan (CAS No. 53973-98-1) is a low viscosity, low molecular weight, sulfated polygalactan polymer used exclusively in clinical diagnostic applications. The polymer is derived from the molecular backbone of carrageenan.
Terminology
The name "poligeenan" was confirmed in 1988 by the United States Adopted Names (USAN) Council. The Council is sponsored by the American Medical Association, the American Pharmaceutical Association, and the US Pharmacopeial Convention Inc.
Prior to 1988, poligeenan was referred to as "degraded carrageenan" in the scientific literature. The terms "poligeenan" and "degraded carrageenan" were often used interchangeably in research articles and reports. The use of the term "degraded carageenan" caused confusion, which resulted in the attribution of the negative observations associated with the polymer being attributed to carrageenan. Poligeenan and carrageenan are completely different products.
Usage
Diagnostic
The primary use for poligeenan is for clinical diagnostic applications, and specifically the suspension of barium sulfate slurries used in X-ray studies of the mouth, throat, and esophagus during swallowing.
Begin with the source’s own compact description: “Poligeenan” is type of polymer. The dossier treats that line as a proposition to test through Poligeenan, type and polymer, not as a finished interpretation.
Why this record matters
The phrase “type of polymer” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jan 29, 2026. The linked authority identifier is Q19830656. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1988.
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.
How to read it
Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
