Petroleum Jelly,
also called Petrolatum or Vaseline, is a translucent,
yellowish to amber or white, unctuous substance having almost
no odour or taste, derived from petroleum and used principally
in medicine and pharmacy as a protective dressing and as a
substitute for fats in ointments and cosmetics. It is also
used in many types of polishes and in lubricating greases,
rust preventives, and modeling clay.

In the Pharmaceutical industry, petroleum jelly
is mainly used as as a base material and to regulate consistency
and is also an active constituent in ointments and creams
(dermatological preparations). The effect of petroleum jelly in the formulations
of cosmetic products is chiefly due to its
highly lipophilic character. Petroleum jelly is used as a
masking ointment, as a vehicle system for peripheral active
substances, and as a base for hydrophilic systems containing
emulsifiers. Petroleum Jellies add lubricity and
moisture resistance to lotions, creams, ointments, and hand
cleaners. Our petroleum Jellies are available in a
variety of colours and consistencies.
Some Key Properties and Effects of Petroleum Jelly:
Highly occlusive and lipophilic. Servers as a medium for
pharmaceutical APIs.
Use of white petroleum jelly
White petroleum jelly has a wide range of uses. It is a
constituent of many products, including barrier creams, hand
cleansing pastes, body lotions, hair care products, hand and
skin creams, lip-care sticks and foot creams. It is used
in profusion in various dermatological formulations, where its
rheological nature is clearly visible.
The most important
properties of petrolatum which include melting point,
consistency, fiber length and color are controlled to close
tolerances by using carefully selected raw materials and the
most advanced methods of manufacturing.
The fiber length of
these grades is medium to long which is the most desirable for
pharmaceutical and cosmetic use.
