Peter Greven - Peter Greven: Your partner for pharmaceutical excipients

Oleochemical additives are among the most important and extensively used excipients in the pharmaceutical industry. Formulation requirements continue to demand higher performance ingredients and industry regulation is increasing.

Peter Greven began addressing these requirements many years ago and dedicated a production facility for the manufacture of vegetable stearates.

Today, Venlo manufactures pharmaceutical grade stearates of uncompromising quality, consistency, performance and regulatory compliance. The complexity of operations requires a continuous process of improvement and customisation. For decades we have embraced this challenge and are now the global market leader for Pharmaceutical Stearates.
