Emulsifying and refattening agents for ointments

Due to their amphiphilic molecular structure, lecithins and phospholipids are ideal substances to be used as emulsifiers or co-emulsifiers in topical medication. They are the “emulsifiers nature created for itself”. In an ointment, lecithins and phospholipids have a refattening effect on the skin. For active ingredients they can act as a penetration improver.

Emulsifying and suspending aid

Many liquid formulations are emulsions which contain two immiscible phases. Our lecithins and phospholipids are interface active and an effective way to keep oil in water as well as water in oil emulsions stable, preventing separation of the phases. Suspensions can also be stabilized by lecithins and phospholipids.

Phosphatidylcholine is a phospholipid which is very easy to hydrate and to disperse. It stabilizes most effectively oil in water emulsions. Therefore we offer a top class range of phosphatidylcholine (PC) enriched to nearly pure products (min. 30% PC in Epikuron™ 130 P to min. 92% PC in Epikuron™ 200) to provide a suitable solution for nearly all oil in water emulsions.
