Ultramarine Pink Pigment, Cosmetic Grade – KT-40003A

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.

Kolortek Ultramarine Series — Hue Positioning

Kolortek supplies three Ultramarine variants within the Cosmetic Matte Oxides range. All share CI 77007 chemistry, the same regulatory approvals, and the same acid sensitivity profile — the hue difference arises from process variations in the calcination step. The table below shows where KT-40003A Pink fits relative to the Blue and Violet grades.

All three Ultramarine grades share CI 77007 classification, identical regulatory status, and the same acid sensitivity (decomposition below approximately pH 3). They are blend-compatible with each other and with all other cosmetic oxide grades.

Key Technical Characteristics

Inorganic pink — lightfastness where organic pinks fail: Organic pink dyes and lakes used in cosmetics — including certain D&C Reds and rhodamine-based colorants — are susceptible to photodegradation under UV and visible light, particularly in transparent or translucent packaging. Ultramarine Pink, as an inorganic aluminosilicate pigment, does not contain the organic chromophore structures that fade under light exposure. For pressed powder compacts, blush products, and any cosmetic with extended retail shelf display life, the lightfastness of Ultramarine Pink is a material formulation advantage over organic alternatives.

Warm pink hue — the reddest end of the Ultramarine range: Ultramarine Pink occupies the warmest hue position in the CI 77007 family. Where Ultramarine Violet sits between blue and red-violet, Ultramarine Pink shifts further toward a true warm pink — closer to rose than to purple. In color development terms, it functions as the inorganic pink primary for blush, eye shadow highlight shades, and soft lip formulations. Its violet undertone distinguishes it from iron oxide reds and D&C lake pinks, making it useful for achieving cool-warm rose shades that neither iron oxides nor organic lakes produce cleanly.

Blend directions for pink and rose cosmetic shades: KT-40003A is a practical building block for the pink-rose-blush color family. Key blend directions: Ultramarine Pink + TiO₂ → pastel blush pink and soft rose; Ultramarine Pink + iron oxide red → deeper coral-rose; Ultramarine Pink + Ultramarine Violet → mauve and dusty pink; Ultramarine Pink + carbon black → muted rose-grey. Tinting strength is moderate — addition rates are typically 1–8% in pressed powder formulations depending on target shade depth.

Non-migrating in wax and oil matrices: As an insoluble pigment, KT-40003A does not dissolve into lipstick wax bases or emulsion oil phases. Color is fixed within the particle and does not bleed into adjacent formulation layers during storage or on the skin during wear — a property that organic dyes and some D&C lakes in solvent-miscible forms cannot reliably deliver.

Application Range

Formulation Notes

Pre-dispersion for pressed powder applications: Ultramarine Pink tends to agglomerate as dry powder. Pre-wetting with 2–5% of a light cosmetic ester (isopropyl myristate, caprylic/capric triglyceride) before blending into the powder base significantly improves color uniformity and reduces visible specks in the finished compact. For lipstick, grinding into the wax phase above melt temperature before pouring into molds gives more homogeneous color distribution.

pH verification for aqueous systems: Confirm the complete formulation pH remains above approximately pH 4 under all production and storage conditions before specifying KT-40003A in any water-based or emulsion product. Blush-toned skincare emulsions, tinted moisturizers, and liquid foundations may contain acidic actives that could compromise stability over time. Stability testing at 40°C over 12 weeks is the standard qualification method for ultramarine-containing aqueous cosmetics.

Kolortek has supplied cosmetic grade inorganic pigments including the full Ultramarine range for over 20 years. Certificate of Analysis documentation per production lot covering heavy metal impurity levels is standard — the key document required for cosmetic ingredient supplier qualification and EU CPNP notification support. The complete Kolortek cosmetic oxide range covers iron oxides (yellow, red, black, brown), TiO₂, three Ultramarine variants, chromium green oxide, and carbon black — enabling single-supplier sourcing for the full matte colorant palette.

Frequently Asked Questions

Q: How does Ultramarine Pink differ from D&C Red lake pigments in cosmetic blush formulations?
A: D&C Red lake pigments (such as D&C Red 7 Lake or D&C Red 33 Lake) are organic dye-based and provide higher chroma and stronger tinting strength per gram, but are more susceptible to photodegradation over time — particularly in clear-packaged products with retail light exposure. Ultramarine Pink is an inorganic pigment with lower chroma but inherently superior lightfastness. In formulation practice, many blush and eye shadow formulators use Ultramarine Pink as the stable inorganic base and supplement with small amounts of D&C lake for additional saturation, rather than relying on organic colorants alone.

Q: Is KT-40003A approved for use in eye shadow?
A: Yes. CI 77007 (Ultramarines) is approved for use in the area of the eye under FDA regulations and listed in EU Annex IV for eye-area use. This applies to all three Ultramarine variants (Blue, Violet, Pink). Verify the current approved use conditions for your specific product category and target market before production specification.

Q: Can Ultramarine Pink be used in cold process soap without morphing or discoloring?
A: Yes. Ultramarine Pink is a well-established cold process soap colorant and is stable in high-pH alkaline environments. It does not morph (change color in the presence of sodium hydroxide) — a common concern with some organic pink dyes in cold process applications. Usage rates typically run 1–3% of total batch weight. Pre-disperse in a small amount of lightweight cosmetic oil before adding to the soap batter for more even color distribution.

Q: What is the difference between Ultramarine Pink and Ultramarine Violet?
A: Both are CI 77007 inorganic pigments. Ultramarine Violet has a blue-violet tone — sitting between blue and pink on the hue wheel. Ultramarine Pink has the warmest, most red-biased hue in the Ultramarine family — closer to a true pink-rose. In blends, Ultramarine Violet tends toward purple and mauve; Ultramarine Pink tends toward rose and soft coral. They are blend-compatible and can be combined to create intermediate violet-pink tones.
