Pharmaceuticals

We produce a range of high-purity pigments for clinical and medical use. Subject to rigorous validations our specialist pharmaceutical products are approved for use in the manufacture of tablet coatings, gelatin capsules, nutraceuticals, liquid suspensions and contrast agents.

We are a leading developer of TiO₂ anatase and rutile pigments that offer the high levels of whiteness and opacity needed in the most demanding pharmaceutical formulations. With the ability to control particle size distribution, we can ensure consistency of color, opacity and surface texture, while extending protecting active pharmaceutical ingredients from light damage and extending their shelf life.

As well as enhancing the aesthetics of pharmaceutical products, our performance additives play a vital part in medical procedures. Available in multiple particle sizes, our barium sulfates can be used to create X-ray contrast agents that precisely match personal profiles. These products are also used to produce X-ray-opaque plastics for catheters, drainage tubes and hypodermic needles. They are also employed in composites containing bone cement that need to show up in X-ray images.

Key brands and products

Titanium dioxide

HOMBITAN^® AFDC101 pigment: Titanium dioxide grades notable for excellent opacity and optimum dispersibility in aqueous media

HOMBITAN^® FF-Pharma pigment: An important excipient for achieving excellent products including tablets, gelatin capsules, nutraceuticals and dietary supplements with slightly hydrophobic properties

Barium sulfates

BLANC FIXE^™ XR-HX and HN barium sulfates are used in contrast agents for X-ray examinations of the gastrointestinal tract and in X-ray-opaque materials. They are also used as a contrast-agent additive in bone cement:

BLANC FIXE^™ XR-HX barium sulfate: A particularly fine barium sulfate with average particle size approx. 0.7 µm
BLANC FIXE^™ XR-HN barium sulfate: This standard product has an average particle size of approx. 1 µm

BLANC FIXE^™ XR-HR6, HR8 and HR10 are high-purity precipitated coarse barium sulfates that are ideally suited to highly filled,
low-viscosity contrast-agent suspensions for double-contrast procedures. BLANC FIXE^™ XR-HR grades can be used in combination with each other and / or with Venator's fine-particles HX and HM barium sulfate grades

SICOVIT^® pigments: Our high purity iron oxide range is developed to meet the most stringent of pharmacopeia standards. SICOVIT® pigments are produced at our dedicated high-purity iron oxide production facility, which is cGMP certified and offers a carefully controlled environment, with extremely high levels of microbial control.
