IFRA critical Effect :Sensitization
IFRA fragrance material specification :
 Should not be used as fragrance ingredients such that the total level in finished cosmetic products exceeds 0.02%, individually or in combination. Based on test data showing sensitising potential for these materials and on evidence of cross-reactivity. (IFRA guidelines)
Fragrance usage is IFRA RESTRICTED to :
Please review all IFRA documents for complete information. (QRA)
IFRA categories : limits in the finished product: (For a description of the categories, refer to the IFRA QRA Information Booklet.)
Category 1 :
See Note (1)
0.003 % (1)Category 2 : 0.004 %
Category 3 : 0.02 %Category 4 : 0.02 %
Category 5 : 0.02 %Category 6 :
See Note (1)
0.07 % (1)
Category 7 : 0.008 %Category 8 : 0.02 %
Category 9 : 0.02 %Category 10 : 0.02 %
Category 11 :See Note (2)
 Notes :
 

For this material, for pragmatic reasons, restrictive levels allowed by the QRA for certain categories but actually being higher than those already in place before applying the QRA, will temporarily not be implemented until the end of a 5 year monitoring phase. At the end of the 5 years the position will be reevaluated again.

 

(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).

 

(2) Category 11 includes all non-skin contact or incidental skin contact products. Due to the negligible skin contact from these types of products there is no justification for a restriction of the concentration of this fragrance ingredient in the finished product.

recommendation for (Z)-beta-damascone flavor usage levels up to :
  30.0000 ppm in the flavor.
