SOFTIGEN® 767 as a solubilizer & penetration enhancer for topical applications

10. February 2023

In the topical application of drugs and for their therapeutic success, the development or the selection of the formulation of the active ingredient carrier is of crucial importance. The excipients used play a key role in delivering active ingredients into the skin with the desired release profile. Moreover, the aesthetic, cosmetic and organoleptic properties of a semi-solid dosage form also contribute directly to the success of the therapy if patients like using it.

IOI Oleo GmbH is committed to the production of lipidic excipients of the highest quality, which have been used in the pharmaceutical industry for decades. The multifunctional product SOFTIGEN® 767 solubilizes active ingredients and at the same time has a moisturizing effect an optimal combination for topical formulations.

In hardly any other application is the combination of function, regulatory compliance and pleasant skin feel as important as in drugs for topical application. This dosage form is very popular because of the local administration. At the same time, however, especially in the treatment of chronic diseases, the selection of excipients in the formulation must be checked very carefully. A balancing act must be achieved between caring properties, comfort and high effectiveness of the drug.

SOFTIGEN® 767 as a solubilizer and penetration enhancer

Various studies show that the majority of API candidates entering clinical trials as NCEs (new chemical entities) do not reach market maturity in a finished medicinal product. Besides a lack of efficacy and toxicological concerns, insufficient bioavailability significantly reduces the chances of successful market approval (link to an article in ScienceDirect).
