Abstract
The present invention relates to a method for producing petrochemical-free aroma components, which comprises extracting aroma components from plant materials with a volatile ester such as ethyl acetate. The method produces unique concrete, wax and absolute components that are useful in all types of fragranced compositions, which compositions, due to the absence of petrochemicals, can be certified as organic.
