The European Commission published today a final opinion of the Scientific Committee on Consumer Safety (SCCS) regarding fragrance allergens in cosmetic products. Earlier this year we have discussed the preliminary opinion of the SCCS (Scenting... new regulations), which aimed at identifying potentially allergenic fragrance ingredients. Aside the already known 26 ingredients (that have been identified in 1999), additional 30 individual chemicals and 26 natural extracts were added to the list. The opinion suggests the tolerable concentration limits for some of these ingredients that would be unlikely to cause allergies with consumers. Based on the SCCS opinion, the Commission will now consider whether any regulatory measures need to be taken.
