Petroleum jelly is a semi-solid mixture of mineral oils and waxes derived from crude oil [1]. Here’s a simplified breakdown of the manufacturing process:
Refining Crude Oil: Petroleum jelly is a byproduct of crude oil refining. During this process, various fractions are separated from crude oil based on their boiling points.
Extracting Wax and Oil Fractions: Fractions suitable for petroleum jelly production, like paraffin wax and mineral oils, are separated from the crude oil [1].
Purification: The waxes and oils are treated with processes like filtration through activated clay or bauxite to remove impurities, colour, and odour [1]. This stage helps ensure the final product is clear, odourless, and safe for use on the skin.
Blending: The purified waxes and oils are mixed in specific ratios to achieve the desired consistency and properties for the final petroleum jelly product [1].
Packaging and Distribution: The finished petroleum jelly is then packaged in containers, jars, or tubes and labelled according to its use (cosmetic or pharmaceutical grade) before being shipped for distribution.
