Business Model

“Proprietary OTC products with scientifically proven efficacy” describes our Health and Well-being products best. We believe that they need to be sold under strong brands which take local market demands into account. Therefore we are offering our Health and Well-being as well as Animal Health and Care products for licensing to be sold under the brands of our customers.
The Cosmetic and Personal Care industry has a high demand for effective and proven active ingredients. Our extremolytes meet these criteria and give creams, foams, and other cosmetic formulations outstanding claims.
As protective agents, extremolytes shield proteins, nucleic acids, and cells against a variety of stress factors. Extremolyte are well suited for the stabilization of biologically active substances in Life Science applications.

Licensable OTC products are widely available these days. But very often these products are neither unique, patent-protected nor do they have scientifically proven claims.

bitop's natural Ectoin®-containing Health and Well-being products fill this gap

  • they possess scientifically proven claims
  • their application is patent protected in the most important global markets
  • their effect is based on 100% natural ingredients
  • they contain Ectoin® “Made in Germany” as a medical ingredient

and they give you the unique opportunity to enhance your own product portfolio and increase your sales.

Not only are our Health and Well-being products backed up by scientific data, our cosmetic active ingredients have been extensively researched by scientists with proven efficacy.

The skincare industry strives for the manufacturing of safe products with substantiated claims. Therefore, we have put emphasis on extensive pre-clinical and clinical testing of our ingredients Ectoin® natural and Glycoin® natural. With bitop’s cosmetic active ingredients you are able to offer products with claims that truly deliver what they promise.


bitop is an internationally operating company that focuses on the development and distribution of proprietary over-the-counter (OTC) products based on Ectoin®, as well as on the supply of Ectoin® natural, and Glycoin® natural as effective cosmetic active ingredients to global cosmetic manufacturers and brands. An additional application field for bitop’s unique extremolytes is its use as biostabilizers.

From extremophilic microorganisms to ready-to-sell medical
products – bitop, a German company, brought Ectoin®, one of the most common extremolytes in nature, successfully to the market for use in humans and animals.

bitop was founded in 1993 as a spin-off from the Faculty of Bioscience at the Private University of Witten/Herdecke (Germany) with the objective of the “biotechnological optimization (“bitop”) of fermentation processes”. Focusing on the manufacturing of Ectoin® in the 1990s, we are today the sole worldwide manufacturer of Ectoin® on an industrial scale. In addition, we have production capacities for another unique extremolyte: Glycoin® natural.

We are proud to be the global Ectoin® expert. For more than 25 years, we have done extensive research and validated Ectoin® as a naturally-derived ingredient for Health and Well-being products. Building on this expertise and knowledge, a unique portfolio of more than 20 products with scientifically proven efficacy has been developed.

The portfolio comprises proprietary OTC products which treat and alleviate symptoms of inflammatory skin diseases, cough and cold, allergies, lung diseases, and dry epithelia. Products for oncology supportive care and animal health were recently added. The same applies to skincare products that treat and prevent environmentally induced skin alterations caused by pollutants, such as fine dust.

Since 2001, Ectoin® natural has been valued and recognized as an efficient, safe, and high-quality cosmetic active ingredient for anti-aging and sun protection formulations. With Glycoin® natural, we offer another innovative cosmetic active of the same quality. Ectoin® natural and Glycoin® natural for cosmetic use are available worldwide through bitop’s distributors or directly at our German plant.
