Justification for type of information:
As indicated in the attached article ( Clark), the typical use of indole is around 200 ppm to 0.01%.
Sometimes this goes up to 1% but above that the odour becomes unpleasant.
Fine fragrances are at most 15-30 % of the total, so at maximum, in an extreme case there would be 0.3 % indole in the end product.
More typically, for say a shampoo or functional product, the fragrance element is only up to 1% of the total product (often 0.2-0.5%) so the amount of indole is extremely low. In any event, the amounts we are talking about in the fragrances themselves are extremely small. The exposure can be negligible.
