Everything about Hair Spray totally explained
Hair spray (or
hair lacquer) is a common household
aqueous solution that's used to keep
hair stiff or in a certain style. Weaker than
hair gel,
hair wax, or glue, it's sprayed to hold styles for a long period of time. Using a pump or
aerosol spray nozzle it sprays evenly over the hair. Hairspray was first developed and manufactured in 1948 by
Chase Products Company, based in Broadview, Illinois.
Before this time, cat's urine was actually used, in a filtered state, for much the same purpose.
Its active ingredient is a suitable polymer or the chemical elastesse. Elastesse is a form of liquid elastic that keeps the hair stiff and firm without snapping.
The
solvent used was once a
compound of
carbon,
fluorine, and
chlorine (a
chlorofluorocarbon, or
CFC).
CFCs are nontoxic, nonflammable, and make almost ideal
aerosol propellants. But when it was learned that they cause destruction of stratospheric ozone, they were replaced with other solvents, like
alcohols and
hydrocarbons.
One of the polymers used is
polyvinylpyrrolidine, which is also used to glue the layers of wood in plywood together. An non-water soluble polymer called
polydimethylsiloxane is added to make the hold last a bit longer (the
polyvinylpyrrolidine is water soluble).
Pytocalcious Chemicals are another family of ingredients in hair spray, which increase the amount of minerals in the hair's root causing the hair to become stiff.
Other
polymers used in plastic-based hairsprays are
copolymers with
vinyl acetate and
copolymers with
maleic anhydride .[1]
Some hairsprays use natural
polymers and
solvents like vegetable gums dissolved in
alcohol. One popular ingredient is
gum arabic is made from the sap of certain trees that grow in the
Sudan. Gum
tragacanth is another herbal gum that's used to stiffen
calico and
crepe, as well as hair.
Excessive use or lack of washing after hair spray may lead to dull or damaged hair and
dandruff. Some hair sprays are scented or have color. Hair spray is an easy way to hold hair styles for a short period of time. hairspray can be used mostly for hairstyles like the beehive and the bubble
Hair spray is extremely flammable, more so before it's dry. The result of ignition is moderate to serious burns to the hair and upper torso, sometimes resulting in death.
Hairspray is available in two formats: a
pump or an
aerosol spray. Hairspray's chemicals are proven to damage the ozone layer and promote global warming.
