D&C Orange 4 is an oil-soluble azo dye that produces a vibrant, mid-orange shade. It is approved for use in externally applied drugs and cosmetics. Its solubility in oils and waxes makes it an excellent colorant for anhydrous formulations. It is a popular choice for providing a strong and stable orange color in products like lipsticks, blushers, and oil-based creams where a water-soluble dye would be ineffective.
