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.
In the presence of tree moss extracts, the level of oak moss in the respective category has to be reduced accordingly such that the total amount of both extracts does not exceed the maximum permitted level in each category as listed in the table above.
If the same compound is intended for more than one IFRA QRA category, then the most restrictive limitation (based on foreseen use concentrations and maximum permitted level) will apply.
(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) (http://www.iofiorg.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.
Oak moss extracts used in fragrance compounds must not contain added tree moss, which is a source of resin acids.
Traces of resin acids may be carried over to commercial qualities of oak moss in the manufacturing process. These traces must not exceed 0.1% (1000 ppm) dehydroabietic acid (DHA) in the extract.
The concentration of resin acids in oak moss can be measured with an HPLC Reverse Phase – spectrofluorometry method.
Further, levels of atranol and chloroatranol should each be below 100 ppm in oak moss extracts.
