Definition of Paraffin Wax

Paraffin wax is derived from petroleum and is an ingredient in numerous household items. It is composed of solid straight-chain hydrocarbons. The name "paraffin" was originally used to categorize a group of hydrocarbons, currently known as alkanes.

Extraction Process

Paraffin is separated from petroleum through a cooling process. When chilled, waxy substances, including paraffin, become hard and insoluble in the petroleum. After extraction, paraffin is purified with chemicals, decolorized and separated into different categories through distillation.

Characteristics

Paraffin is white or colorless and hard. Paraffin melts at 120 to 150 degrees F and is soluble in petroleum at these temperatures.

Uses

Paraffin is used in everyday household products, including candles, waxed paper and cosmetics. Paraffin retains heat, making it a good additive in drywall used to build houses. During the day, the wax softens and absorbs heat; at night, the wax hardens and releases the heat.

Synthetic Paraffin Wax

Synthetic paraffin wax is white and harder than the non-synthetic form. Due to its high purity, synthetic paraffin can be a substitute for certain vegetable waxes and plastics, such as polyethylene.

Uses of Synthetic Paraffin Wax

This form of paraffin can be used as durable floor wax, and for waterproofing and rust prevention.
