Cosmetic Oxides

D&C Red 6 Sodium Salt is an organic lake pigment used to deliver stable red coloration in cosmetic systems where dye migration must be controlled. As part of Kolortek’s **cosmetic matte pigment range**, it provides a **flat, non-pearlescent color effect** with good compatibility in oil-based and low-water formulations such as nail polish and lip products.

D&C Red 7 Lake (45%) is an **organic lake pigment** designed for stable red coloration in cosmetic systems where **controlled bleeding and consistent tone strength** are required. The 45% dye loading provides a balanced approach between color intensity and dispersion control, making it suitable for nail, lip, and face formulations.

D&C Yellow 10 Lake gives formulators a greenish-yellow matte pigment that holds its position in wax, oil, and powder matrices without migration — the property that makes the lake form the correct specification for nail lacquer, lip color, and pressed powder over the soluble dye equivalent. At cosmetic grade, it has been processed to remove regulated heavy metal impurities, and Kolortek supplies it with full documentation for supplier qualification and regulatory submissions.

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.
