Canwax Inc. certifies through its manufacturers that this fragrance product is in compliance with the standards of the International Fragrance Association, provided the fragrance is used in the above application(s) at the noted maximum concentration levels. The "Maximum Use Level for Skin Exposure" is the amount of fragrance, flavour, and essential oil that can come in contact with the skin.

Note that different oils perform differently on similar bases. Please review the IFRA Compliance Certificate listed under the MSDS Tab for more information.
