What is “Color Traveling”?

By: Tony Taniguchi

Color traveling” is one of the major concerns that chemists have when formulating. So what exactly is “Color Traveling” in a formulation? Color Travel occurs when a finished formulation’s shade is not uniform throughout the product. Unlike “color differences” between the product applied on the skin versus the final product, color change by “color travels” happens instantaneously as the product is rubbed away, revealing the “under tone” is different from the surface layer.

The below picture shows a typical example of color travel. The first image uses PRIMROSE pigments. In this sample, there is no difference in pigmentation from where the sample is rubbed. In the two samples to the right, color travel is visibly noticeable in both the untreated and surface treated samples.

Color Travel becomes more noticeable when the bulk is heated to a high temperature. In this example, the bulk was heated between 96 – 108 ℃, as it needs to go through hot-pour process. Despite this harsh condition, the foundation color did not change in the PRIMROSE sample.

PRIMROSE pigments create formulas that are true to color and prevents color travel, and because it remains uniform at high temperatures it also means that users can easily find shades that are perfectly matched to their skin tone. PRIMROSE pigments make shade matching very easy from manufacturer standpoint. This is an excellent example of PRIMROSE’s wet and dry color fidelity and its Primrose has heat-resistant property.
