Selecting a Stable Deep Red Oil-Soluble Color (D&C Red 17) for Body Oil

The D&C Red 17 (CI 26100) (Oil-Soluble, EasyDissolve) is an excellent choice for achieving a deep red color in a body oil formulation.

Here is a strong recommendation based on your requirements for stability and color:

Recommendation: D&C Red 17 (CI 26100) (Oil-Soluble, EasyDissolve)

This product (ID 1877) is a highly concentrated, oil-soluble dye that is specifically formulated to meet your needs for a deep red color in oil-based products.

Addressing Stability Concerns (No Precipitation & No Fading):

1. No Precipitation (Sedimentation):

   • The EasyDissolve type is designed for superior solubility in oil, which minimizes the risk of precipitation or sedimentation in the final product, provided it is fully dissolved during the mixing process.
   • Mixing Tip: To ensure complete dissolution and prevent sedimentation, mix the dye into a small portion of the oil phase first, using gentle heat (ideally below 60°C), until the solution is perfectly clear before incorporating it into the rest of the body oil. Always use the dye at a very low concentration, as it is highly potent.

2. No Fading (Color Stability):

   • Like most oil-soluble dyes, D&C Red 17 has limited heat resistance. To prevent color fading during manufacturing, avoid high temperatures and prolonged heating.
   • Post-Manufacturing Stability: For the final body oil, ensure the product is stored in a container that minimizes light exposure (e.g., amber or opaque bottles) and is kept away from direct sunlight, as UV exposure is the primary cause of fading for most cosmetic dyes.
