IFRA fragrance material specification:
 On the basis of established maximum levels of this substance in commercially available natural sources (like essential oils, extracts and absolutes), exposure to this substance from the use of these oils and extracts is regarded acceptable as long as the level of 7-Methoxy-coumarin in the finished product does not exceed 100 ppm. Furthermore, these natural extracts should not be used as substitutes for this substance. Examples for potential natural sources (with indicative maximum levels) of 7-Methoxy-coumarin are: Camomilla matricaria EO 0,1 % Camomilla matricaria absolute (volatile part) : 5 % Lavandin absolute: 5 % (on the total absolute). Lavander and lavandin essential oils : <0,02 % Lavender absolute: 5 % (on the total absolute). Lime cold pressed oil: 0,1 % Tarragon absolute: volatile part: 5 % Tarragon essential oil : <0,1 %
