Promising Trends from the US Market – IOI Oleo already has the answers

By |5. October 2021|Pharma, Trade Fairs|

A trend that we are seeing in the market in the USA is the improvement of patient compliance. "Take 1 tablet instead of having to think about regularly taking 3 tablets a day." A trend that we are seeing in the USA addresses just this topic. The goal is to ensure the release of the active ingredients over a longer period after administration. This enables longer intervals between doses and, as a result, improved quality of personal life and an increased chance of successful treatment.

SOFTISAN® 649 – THE plant-based synthetic Lanolin Alternative

By |12. August 2021|Pharma|

Lanolin or wool wax is a versatile ingredient and was used medicinally in ancient times. Lanolin is the secretion from sebum glands of sheep and is formed on the surface of their skin. However, the animals have to be treated with pesticides to protect them from parasites. The problem here is that these pesticides accumulate in the wool wax and can later lead to strong allergic reactions in users. This motivated IOI Oleo GmbH to develop a plant-based, synthetic alternative: et voila, SOFTISAN® 649 has since enriched our portfolio and has, among other things, made a name for itself as a lanolin substitute in the pharmaceutical industry.

MIGLYOL® as the Worldwide Benchmark for Injectables

By |29. June 2021|Pharma|

An infusion can save lives and is used as a basic therapy in all areas of health care. The therapy, however, is complex and error-prone. Just as the patient relies on the correct diagnosis by the doctor and the proper execution by the specialist staff, so must the doctor and specialist staff rely on the quality of the infusions. With the MIGLYOL® product portfolio, the Pharma business unit of IOI Oleo GmbH offers high-quality carriers for injectables (infusions and injections).

EU GMP-Production – Quality Made in Germany you can rely on

By |3. June 2021|Pharma|

In the early 2000s, the team of the IOI Oleo GmbH Pharma Business Unit asked themselves: Why do the principles and guidelines for active ingredients not also apply to excipients? As a result, the production site in Witten was GMP-certified, making IOI Oleo GmbH one of the first manufacturers of excipients to be GMP-certified. The certificate was recently confirmed again.

Engineered Lipid Excellence – Made in Germany

By |1. March 2021|Pharma|

Hardly any other area today is as highly regulated by the legislature as the pharmaceutical industry. However, there are currently no manufacturing guidelines for lipid-based excipients, although most drugs consist for the largest part (75 to 99%) of excipients. The team of the Pharma Business Unit at IOI Oleo GmbH is aware of its responsibility as a globally known provider of oleochemical specialties for pharmaceuticals. We were the first company to receive a GMP certificate for our excipients, although this is only required for active ingredients.
