Qualifying an excipient source is a paperwork exercise as much as a chemistry decision. Teint is a pharmaceutical excipients manufacturer with over 20 years of GMP-tested production, and as your direct pharmaceutical excipients supplier we back every batch of Iron Oxide (Red/Yellow/Black) and Titanium Dioxide (Medical) with pharmacopeia compliance, CoA/MSDS documentation for review, and free 50 g–200 g samples for laboratory trials.
Both families are manufactured under GMP conditions, and each one answers a different formulation brief. Review the official comparison, then apply your dosage form to the decision guide below.
| Product Category | Standard Compliance | Main Applications | Key Features |
|---|---|---|---|
| Iron Oxide (Red / Yellow / Black) | ChP / USP / EP | Tablet Coating, Capsules | Ultra-Low Heavy Metals, High Tinting Strength |
| Titanium Dioxide (Medical) | ChP / USP | Film Coating, Opaque Capsules | Exceptional Whiteness, High Dispersion |
Use your formulation objective to choose the right product family, then request a sample that matches the specification you must hit.
Challenge: You need a reproducible colored coating for brand identity or dose differentiation.
Spec alignment: Iron Oxide (Red/Yellow/Black) offers high tinting strength with ultra-low heavy metals and complies with ChP/USP/EP.
Challenge: Your capsule formulation needs a stable pigment that survives shell processing.
Spec alignment: Iron Oxide colorants are approved for capsule use and meet ChP/USP/EP; ultra-low heavy metals keep the oral daily load negligible.
Challenge: You want an even white finish without lumps or poor dispersion in the coating suspension.
Spec alignment: Medical Titanium Dioxide provides exceptional whiteness and high dispersion, with ChP/USP compliance.
Challenge: Light-sensitive or moisture-sensitive ingredients need a capsule shell that blocks light consistently.
Spec alignment: Titanium Dioxide (Medical) delivers the whiteness and dispersion needed for opaque, uniform capsule shells.
When sourcing iron oxide or titanium dioxide for solid oral dosage forms, build your decision around documentation as much as powder properties.
Shorten the approval cycle when you already know which specification your next formulation requires.
Tell the team your dosage form, target shade or whiteness level, and the pharmacopeia standard you report against.
Ask for a free sample — typically 50 g–200 g — together with CoA/MSDS documentation and compliance statements.
Test tinting strength, whiteness, dispersion, and heavy-metal data against the requirements of your own formula.
Return with validated results, request bulk pricing and lead times, and qualify Teint as your documented excipient source.
Get free samples, CoA/MSDS documentation, and expert application guidance from a GMP-tested manufacturer.
send an inquiry through the product page or the contact page and state your dosage form and target shade. free samples are typically 50 g–200 g for pharmaceutical manufacturers, which is enough powder for a meaningful bench trial.
iron oxide (red/yellow/black) complies with chp, usp, and ep. medical titanium dioxide complies with chp and usp. the product-specific compliance statement is documented on the official product comparison table.
ask for the coa/msds paperwork related to the batch under evaluation, the pharmacopeia alignment statement, and the gmp laboratory test results showing zero contamination and chemical purity.
the documented shelf life is 3 to 5 years from the date of manufacture under proper storage conditions. confirm storage recommendations at the time of quotation so your warehouse plan matches the batch record.
iron oxide (red/yellow/black) is used for tablet coating and capsules, where its ultra-low heavy metals and high tinting strength matter most. medical titanium dioxide is used for film coating and opaque capsules, where exceptional whiteness and high dispersion are critical.
