Research & development

An excellent product is at the heart of every business in the cosmetic industry, and we understand that better than anyone. At E. Tjellesen we have a dedicated team of scientists working in our lab constantly developing new formulas, and executing ideas – even those that might seem impossible to bring to life at first.


When working with private label clients we offer a comprehensive solution guiding you through all steps of the development process ultimately making your visions a reality. The overall process and services we offer with regards to this are:


It goes without saying that sharing our knowledge with you is paramount for us to ensure the best results possible. In order to do this most effectively, the first step in a product development process is having a dialogue about your dreams, wishes and visions for the project. Whether talking the concept in general or more detail-oriented, we are attentive to your ideas. The more information you share with us, the better we can realize your visions.


Formulating cosmetics is as much about craftsmanship as it is about science, which is why our scientists not only have extensive expertise on all things technical but holistic as well. This unique combination of knowledge leads to outstanding quality in your finished product. We want nothing less than excellence for our clients, which is why we invite you to join us in our in-house lab to discuss textures, colours, scents and feel of the products. We create everything from makeup, personal care, hair care, styling products and perfumes uniquely customized to meet your needs and expectations.
