Applications
:
Foods
The consistent
high quality, purity, clarity, sweet taste and low odour
of Glycerine can make your products
smoother, richer, moister and fresher. They play an important
role in food and beverage products by adding humectancy
to dried fruits, reducing water activity in cookies and snack
fillings, and making gum more chewable. Their unique properties
enable them to improve foods and beverages by acting as:
. Additives to
reduce water activity
. Emulsifiers as monoglycerides
for food preparations, especially baked goods
. Heat transfer mediums for frozen foods
. Humectants
. Smoothing agents
. Solvents for food flavoring and colorings
. Sweeteners (glycerine is about
75% as sweet as sucrose)
Nutraceuticals
Because consumers
are concerned about purity, Glycerine
is especially well suited for use in nutraceuticals
by both the food and pharmaceutical industries due to its
high purity and consistent quality. Nutraceuticals are the fastest growing application in the
food and dietary supplement industries. Nutraceuticals
are generally defined as naturally occurring compounds found
in plants and other biological sources and include vitamins,
minerals, microbials and herbs.
They may be a food or a food ingredient that provides a health
or medical benefit.
Pharmaceuticals
For ailments ranging
from poison ivy to angina pectoris, glycerine
is a key ingredient in numerous pharmaceutical treatments.
The high quality and purity, plus low odour and non-toxicity of glycerine
make it one of the most widely used chemicals worldwide in
the formulation of pharmaceuticals.
Glycerine
sweet taste makes them an ideal ingredient in syrups and lozenges.
Glycerine derivatives also are widely used in tranquilizers,
in the treatment of angina pectoris and as expectorants in
asthma therapy.
Other pharmaceutical
uses include:
. Eyewashes
. Contraceptive jellies and creams
. Ear drops
. Poison ivy solutions
. Vehicle and solvent for digitalis and intra-muscular injection
. Sclerosing solutions for treatment
of varicose veins and hemorrhoids
. Suppositories
. Gel capsules
Personal
Care and Cosmetics
Glycerine
are some of the most versatile ingredients and raw materials
found within personal care formulations. They are found in
skin lotions, shaving soaps, deodorant pastes and hair care
products.
In emollient products, they offer key advantages as efficient
humectants or hygroscopic agents. In liquid preparations,
their viscosity provides body and the ability to suspend many
insoluble materials. Elsewhere, their excellent lubricating
properties impart a desirable smoothness. And they offer outstanding
winter shelf life because of their antifreeze properties.
Oral
Care
In dentistry, glycerine
lends body, smoothness and palatability to many dental formulations.
Glycerine is ideal for toothpaste applications, where they
provide the basic medium and serve to keep the paste at the
desired smoothness and viscosity. Plus, their consistently
high purity does not affect the stability and shelf life for
many of the newer toothpastes containing baking soda and hydrogen
peroxide.
Glycerine also are used as solvents
for antiseptics, oral medications, root canal pastes, polishing
compounds, disclosing solutions, mouth washes, stannous fluoride
solutions, dental impression waxes and denture casting materials.
Other
Applications
Other uses where
Glycerine provides the competitive
edge include :
. Adhesives
and pastes
. Agriculture
. Air conditioning and refrigeration
. Construction, furniture and automobile polyurethanes
. Cork gaskets and sealers
. Electrical materials
. Fabric softeners
. Glass and ceramics
. Inks
. Laboratory materials
. Leather
. Metals
. Photography
. Podiatry and chiropody
. Propellants and rocket fuel binders
. Rubber
. Surface and architectural coatings
. Textiles
. Wood
