What Colour is Pure Petroleum Jelly?
Pure petroleum jelly is colorless or a very pale yellow. The color can vary slightly depending on the level of refinement during processing. Highly distilled petroleum jelly will appear colorless, while less refined versions may have a pale yellow tint.
Several factors influence the color of petroleum jelly:
-
Refinement Process: The degree of processing significantly affects the color. Highly refined petroleum jelly, often labeled as "white petrolatum," undergoes extensive purification to remove impurities, resulting in a colorless or nearly colorless product. Less refined versions may retain some impurities, leading to a pale yellow hue.
-
Additives: While pure petroleum jelly is colorless or pale yellow, many commercial brands add fragrances, colors, or other ingredients, changing the overall appearance. Therefore, the color of a commercially available product isn't always indicative of purity.
-
Storage: Exposure to air and light can cause some discoloration over time, but this does not necessarily indicate a loss of quality or safety.
The references support the colorless or pale yellow description of pure petroleum jelly. For example, one reference explicitly states that pure petroleum jelly is "colorless (or of a pale yellow color when not highly distilled)." Other sources highlight the distinction between "white petrolatum," indicating a highly refined, colorless version, and commercially available products that may contain additives impacting their color.
Examples of Petroleum Jelly Products and Their Color
While pure petroleum jelly is colorless or pale yellow, commercially available products often vary in color due to added ingredients:
-
Vaseline: Many Vaseline products are white or have a slight yellowish tint, depending on the formulation. Some, like the "Vaseline® Blue Seal Original Petroleum Jelly," may be slightly more yellow. However, the key is to focus on the description "pure petroleum jelly," not the brand's added tints.
-
Generic Brands: Generic brands can have varying colors due to differences in their purification and formulation processes. A white color doesn't necessarily indicate inferior quality; it may simply reflect a different level of refinement.
