Robertet's world class research labs were industry-leading pioneers in extracting from nature what had formerly only been available as synthetics. As a result, we can offer their extensive and diverse range of aroma chemicals, derived from natural materials, for use in almost any fragrance or flavour product. 

Ancient civilizations macerated vegetable materials in oils and used them for perfuming the skin. In the middle ages Arab scientists developed steam distillation techniques and in the 18th century concentrated alcohol was used to make tinctures. Solvent extraction was then widely used in the early 1900's.


Technological advances have meant that modern processes can now extract relatively pure single aroma chemicals or isolates from natural materials for use in fragrances and flavours for almost any product variant.
