Polyvinylpyrrolidone (PVP) to some is thought of as being a "miracle" polymer
because it has so many almost amazing applications. In filtration science,
it is known most widely as a treatment for membrane filters to make them
more wettable to enhance filtration kinetics. In the microscopy and
histology laboratory it is also used as an osmotic adjustor for certain
resin systems such as LR Gold. To those working in the cosmetics and
toiletries industry, PVP is often times the polymer that gives a hair spray
product it desired characteristics, the polymer has a tendency not only to
want to coat the hair, but it also tends to be attracted to keratin, and
when rinsed, it tends to want to "stick" to the hair. Since it does exhibit
some mount of conductivity, when hair is combed, the static charge is
carried away, and especially those with long hair don't have as great of a
tendency to get the "frizzies". However, don't try to make your own conditioning
shampoos with the SPI-Chem PVP because what is used in the cosmetics
industry is a hydrolyzed form of PVP.
And these characteristics sometimes also have application in electro static
discharge (ESD) control since a surface can be easily treated (by dipping
into an aqueous solution of the polymer) and rendered at least to some
degree, surface conductive. UV curing the treated surface tends to make it
even more wetable but some times the electrical conductivity properties are
reduced (as reported to us by those who have used PVP).
Stabilizing agent for glucose tests. Encapsulation & controlled release agent. Binder, stabilizer, protective colloid, and is an excellent film former.
