Terpeneless, sesquiterpeneless lime oil is prepared from distilled lime oil, rarely from expressed lime oil, by the conventional methods of deterpenation.
Where the bergapten (5-methoxypsoralen) content of all relevant oils present in a compound has been determined, it is recommended that for applications on areas of skin exposed to sunshine, excluding bath preparations, soaps and other products which are washed off the skin, the total level of bergapten in the consumer products should not exceed 0.0015% (15 ppm). This is equivalent to 0.0075% (75 ppm) in a fragrance compound used at 20% in the consumer product.
Where the level of bergapten has not been determined by appropriate methods, the limits specified in the guidelines on individual oils should apply.
In those cases, where such oils are used in combination with other phototoxic ingredients, the additive effect has to be taken into consideration and the use levels have to be reduced accordingly. The sum of the concentrations of all phototoxic fragrance ingredients, expressed in % of their recommended maximum level in the consumer product, shall not exceed 100.
