Analyses are performed in-house and at approved laboratories according to valid methods. Conformity of our Chitoceuticals® lines to ISO 22442-1, ISO 22442-2 and ISO 22442-3 is guaranteed and verified within audits.

For these reasons, the chitosan products you receive from us are always constant in their properties and quality and thus permanently reproducible. More than 500 customers worldwide have already benefited from our offer and our know-how. Our customers are represented worldwide in the medical technology and pharmaceutical industries.

Due to the broad range of our various chitosan products, we do not have a „Standard Drug Master File (DMF)“ because we are using different processes for individual products. It goes without saying, that we will gladly provide you with relevant information for your product approval. If a chitosan DMF is required for your application, we can make it possible. Please, contact us. 

Since 2016, we have an active DMF Class IV for excipients for our ultrapure chitosan hydrochloride series with the US FDA.
