Vaseline, or petroleum jelly, can be either white or pale yellow. The color depends on the level of refining during its production.
Understanding Vaseline's Color
-
Highly Refined: Highly refined Vaseline is typically white or colorless. This is because the refining process removes impurities that contribute to the yellow tint. Many brands prioritize this for cosmetic applications, associating whiteness with purity. Examples include some formulations of Vaseline Skin Protecting Jelly.
-
Less Refined: Less refined petroleum jelly may have a pale yellow hue. The yellow color is due to residual hydrocarbons and other impurities remaining after processing. This doesn't necessarily indicate lower quality, though some consumers might prefer the white version for cosmetic reasons. Examples include some formulations of Vaseline Blue Seal.
The color doesn't necessarily impact safety or efficacy. Both white and yellow petroleum jelly serve the same fundamental purpose: moisturizing and protecting the skin. The difference lies mainly in the processing and the resulting visual appearance.
