ingredients and transparency
Transparency List

The Transparency List is an ordered register of all fragrance ingredients used in consumer goods by the industry’s customers worldwide. It represents a snapshot of ingredients used at the moment of publication – even those used in very small quantities or those that are being phased out.
This proactive initiative responds to consumers’ needs for more information about the products they use.
The current list contains 3,999 materials that were reported, through the Volume of Use survey, as used in fragrance compounds in 2015. This survey is carried out on a regular basis among IFRA-affiliated member companies, representing approximately 90% of the world’s production volume of fragrances.
This number represents an increase on previous years due in the main to the introduction of a new, more refined nomenclature system for natural extracts, which differentiates ingredients according to the part of the plant used or the processing method, providing greater detail and transparency than the Chemical Abstracts Service (CAS) number system.

For some natural materials there might be multiple entries possible - for example due to providing US CAS and EU (EINECS) CAS numbers and because sometimes one CAS number covers more than one extract from different parts of a plant.
Due to a technical problem, the list now appears as a downloadable PDF. Should you have any issues downloading the document, please contact us via

New ingredients

Any new fragrance ingredients are automatically added to the list to be reviewed by the Expert Panel for Fragrance Safety. We comply with necessary national, regional and international legislation. Our approach is one of ‘safety first’, and this means that the IFRA Board may make additional recommendations to members on the use of ingredients, going beyond legislative requirements.
In any case, the final responsibility for the safety of any fragrance material put on the market rests with the company supplying the material.
