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 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. It does not mean that your base product can perform at these levels. It is imperative that you test each oil in each application for evaluation of desired performance. Note that different oils perform differently in similar bases. Please review the IFRA Compliance Certificate listed under the MSDS Tab for more information.
