If the product is clearly traceable to one of the cosmetic categories listed, it is advisable to use the most recent as the source, and therefore as the method of calculation of the SED in the PIF.
In the event that the product does not clearly fall into one of the cosmetic categories there are two possible selection strategies:
1. The first is to decide to assimilate the product to the cosmetic category that is considered closest to it, specifying in the Reasoning the reasons for this choice. In the Reasoning you could, for example, list the points of convergence of the product to the category in terms of quantity applied, frequency of application or percentage of irritation.
2. The second strategy, on the other hand, is to create an ad hoc cosmetic category for your product.
