The SCCS concludes the following:
1. Considering the recent concerns over the presence of DnHexP as a contaminant in the production of Diethylamino Hydroxybenzoyl Hexyl Benzoate (DHHB) used as a UV-filter in cosmetic products, as well as in view of technical and scientific progress and taking under consideration in particular the various health concerns, the SCCS is requested to identify the maximum safe level of DnHexP as a contaminant in DHHB preparations
Considering the health concerns associated with DnHexP, the SCCS calculated a maximum safe level of 0.026% (260 ppm) for this impurity in the UV filter DHHB. This applies when DHHB is used up to 10% in cosmetic products and only if DnHexP is an unavoidable impurity.
2. Does the SCCS have any further scientific concerns regarding the presence of DnHexP in DHHB as a UV-filter in cosmetic products?
The SCCS has noted from the available information that DnHexP was below the level of detection in several DHHB containing sunscreen products and other DHHB sources, provided that a specific manufacturing process is applied. The information also showed that it is technically possible to lower the levels of DnHexP in DHHB down to 1 ppm. Considering the existence of such alternative manufacturing process for DHHB, the SCCS is of the opinion that a trace level of 1 ppm should be the target for the maximal level of DnHexP as an impurity in DHHB.
