| IFRA Other Specification | < 20 mmoles / liter peroxides |
| fragrance material specification | Linalool and natural products known to be rich in linalool, such as bois de rose, coriander or ho wood oil, should only be used when the level of peroxides is kept to the lowest practical level. It is recommended to add antioxidants at the time of production of the raw material. The addition of 0.1% BHT or alpha-tocopherol for example has shown great efficiency. The maximum peroxide level for products in use should be 20 mmol/l. |
| maximum skin levels for fine fragrances | 0.3100 % and are based on the assumption that the fragrance mixture is used at 20% in a consumer product (IFRA Use Level Survey). (IFRA, 2004) |
