D&C Yellow 10 Lake, Cosmetic Grade Yellow Pigment for Nails & Cosmetics

Regulatory Context: Where D&C Yellow 10 Lake Is Permitted

Regulatory status is the first filter for any D&C colorant specification. D&C Yellow 10 (CI 47005, Quinoline Yellow) exists in both a soluble dye form and this insoluble lake form — and their permitted uses are not identical. The table below reflects generally accepted regulatory standing; always verify current approved use categories with your regulatory team for each target market before specifying.

Common selection error: specifying D&C Yellow 10 Lake for an eye-area product in the US market. Under FDA regulations, this colorant is not on the approved list for use in the area of the eye. Formulators developing eye shadows or eyeliners for FDA-regulated markets must use only those colorants specifically approved for eye-area use.

Technical Specifications

Key Technical Characteristics

Lake form vs. dye form — the formulation-critical distinction: D&C Yellow 10 Lake is insoluble in cosmetic solvents, oils, and waxes. The soluble dye form (D&C Yellow 10) will dissolve into lipophilic matrices and can migrate through lip products or nail lacquer films during wear or storage. For any anhydrous or wax-based system, the lake form is the technically correct choice.

Greenish-yellow hue and its blending behavior: The quinoline-based colorant produces a distinctly greenish yellow — warmer yellows require blending with a red-toned lake such as D&C Red 7 or D&C Red 22. In nail lacquer, D&C Yellow 10 Lake is commonly used as a component in green and chartreuse formulations rather than as a standalone yellow, where its green undertone is an asset rather than a limitation.

Matte texture in nail lacquer: Lake pigments on an alumina substrate contribute a degree of physical matteness to the dried lacquer film. D&C Yellow 10 Lake is used in matte nail formulations both for its color and for the texture contribution of the alumina carrier — a functional property that titanium dioxide or mica-based colorants do not replicate in the same way.

Light stability considerations: Quinoline yellow lakes have moderate lightfastness compared to inorganic pigments such as iron oxides. For products with extended shelf exposure (display cosmetics, products sold in transparent packaging), this is a relevant formulation variable. Contact Kolortek for specific lightfastness testing data if photostability is a requirement for your product specification.

Application Range

Specification Decision Guide

If your formulation is anhydrous (nail lacquer, lipstick, wax crayon) → specify the lake form (this product), not the soluble dye. The dye form will dissolve into the matrix and migrate during storage or wear.

If you need a pure warm yellow rather than a greenish-yellow → D&C Yellow 10 Lake is not the right primary colorant; consider D&C Yellow 5 Lake (CI 19140) for a cleaner yellow, or blend D&C Yellow 10 Lake with a small addition of a warm-toned red lake to neutralize the green cast.

If your product targets the eye area (US market) → D&C Yellow 10 Lake is not approved for eye-area use under FDA regulations. Select from the approved eye-area colorant list for that product category.

If long-term light exposure is a product specification requirement → contact Kolortek for lightfastness data before committing to this colorant. Inorganic yellow pigments (e.g., iron oxide yellow) offer higher photostability but a different hue profile.

Kolortek has supplied D&C lake pigments alongside its broader cosmetic pigment range for over 20 years, with consistent batch-to-batch color and impurity control. TDS, SDS, Certificate of Analysis, and INCI documentation are available on request — the documentation set most buyers need to complete a supplier qualification file or cosmetic product registration.

Frequently Asked Questions

Q: What is the difference between D&C Yellow 10 and D&C Yellow 10 Lake?
A: D&C Yellow 10 is a water-soluble quinoline dye. D&C Yellow 10 Lake is the insoluble version — the dye is precipitated onto an alumina substrate, converting it from a soluble dye into a dispersible pigment. The lake form will not dissolve into oil or wax matrices, which prevents migration and color bleeding in anhydrous formulations. For nail lacquer, lipstick, and pressed powder, the lake form is the standard specification.

Q: Why does D&C Yellow 10 Lake appear greenish rather than a clean yellow?
A: The quinoline chromophore produces a yellow with a distinct green undertone (CI 47005). This is an inherent property of the colorant chemistry, not a quality variation. For formulations requiring a neutral or warm yellow, D&C Yellow 5 Lake (tartrazine lake, CI 19140) provides a cleaner yellow tone. D&C Yellow 10 Lake is most useful in green, lime, and chartreuse shades or where its green cast is intentional.

Q: Is D&C Yellow 10 Lake approved for nail products?
A: Under FDA regulations, D&C Yellow 10 Lake is approved for externally applied cosmetics, which includes nail products. Formulators should verify the current approved use category listing in 21 CFR before specifying. EU and other market approvals should be confirmed separately with reference to the relevant regulatory framework.

Q: What heavy metal impurities are controlled in cosmetic grade D&C lakes?
A: Cosmetic grade D&C colorants are processed to remove or reduce regulated impurities including lead, arsenic, mercury, and antimony to levels compliant with FDA and EU cosmetic requirements. Kolortek supplies Certificates of Analysis documenting impurity levels on request.

Q: Can D&C Yellow 10 Lake be blended with other D&C lakes?
A: Yes. D&C lake pigments from the same series are blend-compatible. D&C Yellow 10 Lake combined with a blue lake (such as D&C Blue 1 Lake) produces green tones; combined with D&C Red 7 Lake it shifts toward orange. Because the greenish-yellow hue is distinctive, small-batch blending trials are recommended before scaling any color match.

Request Samples or INCI Documentation

Whether you are qualifying a new colorant supplier or developing a yellow or green nail lacquer shade, evaluating D&C Yellow 10 Lake in your own system is the most direct path to a specification decision. Contact Kolortek to request a sample, TDS, SDS, Certificate of Analysis, or INCI documentation — the standard documentation set for cosmetic ingredient supplier qualification.
