Editing Polyvinylpyrrolidone (section)

===Other uses===
PVP binds to [[polar molecule]]s exceptionally well, owing to its [[chemical polarity|polarity]]. This has led to its application in coatings for photo-quality ink-jet papers and transparencies, as well as in inks for [[inkjet printer]]s.

PVP is also used in personal care products, such as [[shampoo]]s and [[toothpaste]]s, in [[paint]]s, and [[adhesive]]s that must be moistened, such as old-style [[postage stamp]]s and [[envelope]]s. It has also been used in [[contact lens]] solutions and in [[steel]]-quenching solutions.<ref>{{cite journal |author1=Fischer, Frank  |author2=Bauer, Stephan |name-list-style=amp |title=Ein Polyvinylpyrrolidon (PVP): ein vielseitiges Spezialpolymer – Verwendung in der Keramik und als Metallabschreckmedium |volume=61 |issue=6|pages=382–385 |year=2009 |journal=Keramische Zeitschrift }}</ref><ref>{{cite journal |first1=Alexander |last1=Göthlich |first2=Sebastian |last2=Koltzenburg |first3=Gunnar |last3=Schornick |title=Funktionale Polymere im Alltag: Vielseitig |journal=Chemie in unserer Zeit |volume=39 |issue=4 |pages=262–273 |year=2005 |doi=10.1002/ciuz.200400346}}</ref> PVP is the basis of the early formulas for [[hair spray]]s and [[hair gel]]s, and still continues to be a component of some.

As a [[food additive]], PVP is a [[Stabilizer (food)|stabilizer]] and has [[E number]] '''E1201'''. [[PVPP]] (crospovidone) is '''E1202'''. It is also used in the wine industry as a [[finings (wine)|fining agent]] for [[wine|white wine]] and some [[beer]]s.

In in-vitro fertilisation laboratories, polyvinylpyrrolidone is used to slow down spermatozoa in order to capture them for e.g. ICSI.

In [[molecular biology]], PVP can be used as a blocking agent during [[Southern blot]] analysis as a component of [[Denhardt's buffer]]. It is also exceptionally good at absorbing polyphenols during DNA purification. [[Polyphenols]] are common in many plant tissues and can deactivate proteins if not removed and therefore inhibit many downstream reactions like PCR.

In [[microscopy]], PVP is useful for making an aqueous mounting medium.<ref>Lillie RD & Fullmer HM (1976) ''Histopathologic Technic and Practical Histochemistry'', 4th ed. New York: McGraw-Hill, p. 411. {{ISBN|0-07-037862-2}}.</ref>

PVP can be used to screen for [[phenol]]ic properties, as referenced in a 2000 study on the effect of plant extracts on insulin production.<ref>{{cite journal|doi=10.1021/jf9904517|pmid=10725162|title=Insulin-like Biological Activity of Culinary and Medicinal Plant Aqueous Extracts in Vitro|journal=Journal of Agricultural and Food Chemistry|volume=48|issue=3|pages=849–52|date=March 2, 2000|last1=Broadhurst|first1=C.
