D&C Red 6 Sodium Salt, Cosmetic Grade Red Pigment

FD&C Blue 1 Lake is a dual-listed colorant — approved under both FDA food additive and cosmetic colorant regulations — making it one of the few blue pigments formulators can specify across personal care, nail, and certain food-contact or food-adjacent product categories without switching colorant systems. As a lake form of Brilliant Blue FCF (CI 42090), it is insoluble in water and most cosmetic solvents, which eliminates the dye migration issues that affect soluble FD&C Blue 1 in wax, oil, and pressed powder matrices.

FD&C Red 40 Aluminum Lake at 24–30% dye content is a high-strength, insoluble red pigment used across cosmetic, food, and pharmaceutical applications where a non-migrating red colorant is required. The lake form of Allura Red AC (CI 16035) is precipitated onto an alumina substrate, producing a dispersible powder that holds its color in wax, oil, and anhydrous matrices without the bleed or migration issues associated with the soluble dye form. At 24–30% dye loading, it delivers consistent tinting strength and is suited for formulations where color depth and regulatory compliance need to be met simultaneously.

FD&C Yellow 5 Lake is an **insoluble food-grade lake pigment** designed for applications where **color stability and low bleeding** are required. Compared with water-soluble dyes, it provides better control in oil-based and low-moisture systems, making it suitable for confectionery coatings, pressed tablets, and decorative food applications.

FD&C Yellow 5 Aluminum Lake at 15–22% dye content delivers a clean, neutral yellow in anhydrous cosmetic and food-adjacent formulations where the soluble dye form (Tartrazine) would migrate or bleed through wax, oil, or pressed powder matrices. The aluminum lake conversion of CI 19140 is insoluble in most cosmetic solvents — making it the standard specification for nail lacquer, lip color, pressed powder, and pharmaceutical tablet coatings that require a food-safe yellow without color instability in the finished product.

FD&C Yellow 6 Aluminum Lake is an orange-yellow insoluble pigment derived from Sunset Yellow FCF (CI 15985), precipitated onto an alumina substrate to produce a non-migrating, dispersible lake pigment approved for both food and cosmetic applications. Its dual FD&C listing makes it one of a limited number of yellow colorants that formulators can specify across nail lacquer, lip color, pressed powder, food products, and pharmaceutical tablet coatings without switching colorant systems between product categories. Kolortek supplies this grade with confirmed low heavy metal content and full batch documentation — the baseline requirement for cosmetic and food ingredient supplier qualification.

KT-40001 is a cosmetic grade Ultramarine Blue — a synthetic inorganic pigment that provides a clean, bright violet-blue body color with excellent opacity and low heavy metal content suitable for use across personal care and color cosmetic formulations. Unlike organic blue dyes, Ultramarine Blue is chemically inert, non-migrating, and inherently lightfast — properties that make it a reliable choice for pressed powders, eye shadows, lip products, and soap where color stability over shelf life is a baseline requirement. All Kolortek cosmetic oxide grades are filtered to remove regulated impurities before supply.

KT-40002B is a cosmetic grade Ultramarine Violet — a synthetic inorganic pigment that delivers a red-biased violet body color with the same chemical stability and regulatory acceptance as Ultramarine Blue, but with a distinctly warmer, more purple-red hue character. As a matte, opaque, insoluble colorant, it is non-migrating in wax, oil, and powder matrices and inherently lightfast — making it a practical specification for eye shadows, lipsticks, pressed powders, and soap where stable violet or purple color is required without the fading limitations of organic violet dyes. All Kolortek cosmetic oxide grades are filtered to remove regulated heavy metal impurities before supply.

KT-40003A is a cosmetic grade Ultramarine Pink — a synthetic inorganic pigment that delivers a warm pink-rose body color within the same CI 77007 Ultramarines family as Ultramarine Blue and Ultramarine Violet, but with a distinctly warm, red-pink hue character. As a matte, insoluble, non-migrating colorant with excellent lightfastness and low heavy metal content, it provides a stable pink tone in pressed powder, eye shadow, lip color, blush, and soap formulations where organic pink dyes would fade or bleed over the product shelf life. All Kolortek cosmetic oxide grades are filtered to remove regulated heavy metal impurities before supply.
