Residue wax

Paraffin wax and foots oil are both byproducts of the petroleum refining process, but they have distinct characteristics and applications. Here are the key differences between paraffin wax and foots oil:

Composition

Also Paraffin wax is a solid hydrocarbon derived from petroleum, whereas foots oil is a liquid residue obtained during the production of paraffin wax. Foots oil contains a mixture of heavier hydrocarbons, unsaturated compounds, and impurities.

Physical State

Special differences is Paraffin is solid at room temperature and has a relatively high melting point, typically ranging from 45 to 68 degrees Celsius (113 to 154 degrees Fahrenheit), depending on the grade but Residue wax is a liquid or semi-liquid substance at room temperature.

Appearance and Texture

Appears of wax as a white or colorless solid with a smooth and crystalline texture. It is often sold in the form of wax blocks, flakes, or pellets. foots oil, in contrast, is a dark, viscous liquid with a thicker consistency.

Uses and Applications

Paraffin wax has a wide range of applications, including candle making, food preservation, cosmetics, pharmaceuticals, and packaging. It is commonly used for its heat-retaining properties, moisture barrier capabilities, and ability to solidify and release fragrance. Foots oil, however, has more limited applications. It is primarily used as a raw material for further processing, such as refining and distillation, to produce higher-grade waxes or other petrochemical products.

Purity and Impurities

Purity of Paraffin wax is very high and  compared to foots oil. It undergoes additional processing steps, including solvent extraction and filtration, to remove impurities and achieve a higher degree of purity. Foots oil, being a residue of the wax production process, contains a higher concentration of impurities, such as residual oil, unsaturated hydrocarbons, and solid particles.

Melting and Solidification Characteristics

Paraffin wax has a defined melting point and solidifies at temperatures below its melting point. This property allows it to be melted and solidified repeatedly without significant degradation in quality. Foots oil, being a liquid, does not have a specific melting or solidification point like paraffin wax.
