White Petroleum Jelly
Arvila Gr
White Petroleum jelly, Vaseline jelly or petrolatum is a semi-solid hydrocarbon C15H15N, chemical name 1,1,2-Trimethylbenzeindole. It is translucent in appearance (colour varies from yellowish to amber or white), and is derived from petroleum and principally finds its application in medicine and pharmacy where it is used as a protective dressing.
From the industrial point of view, it finds application in many types of polishes and in lubricating greases, rust preventives and modelling clay.
We, here at DANA ensure that the petroleum jelly we manufacture is in compliance with all IP (Indian Pharmacopoeia), BP (British Pharmacopoeia) and USP (United States Pharmacopoeia) standards.

Extraction procedure
Vaseline jelly is manufactured from the semi-solid residue that remains after steam/vacuum distillation (distillation performed under reduced pressure) of petroleum. After the distillation, the residue is dewaxed and blended with stocks from other sources (along with lighter fractions), to obtain a product with the desired consistency. For the final purification, a combination of high-pressure hydrogenation and sulfuric acid treatment followed by filtration through absorbents.
Classification on the basis of use
White jelly can be broadly categorized into three categories on the basis of application-
- Industrial grade petroleum jelly
- Cosmetic grade white jelly
- Pharmaceutical grade petroleum jelly
Pharmaceutical Grade Petroleum Jelly
- We manufacture pharmaceutical-grade snow-white petroleum Jelly and it is widely used is used by many personal care and pharmaceutical companies as a very versatile, safe and economical formulation base.
Uses of Pharmaceutical grade white jelly
The most common uses of pharmaceutical-grade snow-white jelly are listed as below-
- It can be used to protect minor cuts and burns.
- Pharmaceutical grade petroleum jelly is used to protect and heal dry skin.
- It forms an integral part of skin-protecting ointments and other medicated ointments.
