IFRA categories : limits in the finished product: (For a description of the categories, refer to the IFRA QRA Information Booklet.)
Category 1 :2.00 % (1)Category 2 :2.60 %
Category 3 :10.70 %Category 4 :32.10 %
Category 5 :16.90 %Category 6 :51.40 % (1)
Category 7 :5.40 %Category 8 :2.00 %
Category 9 :5.00 %Category 10 :2.50 %
Category 11 :See Note 
 

(1) IFRA would recommend that any material used to impart perfume or flavour in products intended for human ingestion should consist of ingredients that are in compliance with appropriate regulations for foods and food flavourings in the countries of planned distribution and, where these are lacking, with the recommendations laid down in the Code of Practice of IOFI (International Organisation of the Flavor Industry). Further information about IOFI can be found on its website (www.iofi.org).

 

Note : Category 11 includes all non-skin contact or incidental skin contact products. Due to negligible skin contact, the concentration of a fragrance ingredient should not exceed the usual concentration of the fragrance compound in the finished product.

For example, hypothetically if the usual concentration of a fragrance compound in the final product, for example a candle, is at 5%, then any individual fragrance ingredient (in this case delta-methyl ionone) must not exceed 5% in the candle.
