Essential Oils

Essential oils are natural. Essential oils are versatile. Essential oils are good for body and soul.

Essential oils are at the core of our business. Because they are not only indispensable for us, but also for many cosmetic and pharmaceutical products.

With a range of several hundred essential oils, we meet every standard. And we also set standards: with our Natura® brand, for which we create perfume compositions made exclusively from natural essential oils.

An overview of our most important oils can be found here.

Pharma / GMP

Are you a manufacturer of pharmaceutical products or foodstuffs? Then quality assurance is your top priority. And you are our top priority.

We meet the highest safety standards: in our rooms and facilities as well as in our production processes and hygiene measures. Manufacturers of pharmaceutical products must be able to rely on the purity of raw materials. Düllberg Konzentra is the only supplier of high-quality, natural essential oils of the highest purity according to the European Pharmacopoeia. They are extracted in compliance with the GACP guidelines, rectified in our qualified facilities according to certified EU-GMP standards, safeguarded by regular supplier audits with complete documentation, and supported by validated processes.

Our GMP (Good Manufacturing Practice)-compliant quality management system ensures the safety and quality of all the products we produce and process.

On request, we manufacture all products according to European Pharmacopoeia and GMP guidelines. Individual essential oils as well as compositions. For your capsules, cough syrups or emulsions, or for your coatings or nutraceuticals.


Confectionery, pharmaceutical products or oral care: we don’t want to argue about your taste. But rather cater to it exactly. This is achieved through a wide range of flavours for the most diverse applications: confectionery, pharmaceutical products and oral care.

Oral Care

Dentarom® is the name of the brand under which we bundle our expertise in oral and dental care. For a radiant smile from consumers, and a radiant smile from you.

In our oral care flavourings, essential oils ensure a good taste and, thanks to their antibacterial effect, also fresh breath. Our Dentarom® solutions are therefore used in numerous oral and dental care products from well-known manufacturers: in toothpaste, mouth rinses and dental care chewing gums.


Our strength is the production of flavourings on the basis of essential oils and, if desired, in accordance with European Pharmacopoeia and GMP (Good Manufacturing Practice) guidelines.
