I was very lucky to find some articles that dealt with the contents and fragrance allergens that can be found in almost every children's cosmetic products. Children's products usually do contain fragrances or maskants of some type. I wasn't aware that such extensive work was conducted around the world dealing specifically with children and their reactivity to cosmetic ingredients especially fragrances. You will notice that the studies that will be mentioned here were not conducted in the United States. It is really difficult to gauge the significance of this fact. Numerous studies were conducted in Scandanavian countries that focused on fragrance allergens and how they impact the increasingly growing children's cosmetics market. These studies were conducted not too long ago (about 5 years) and the results may have more relevance today than they did when the studies were run. In some studies conducted in Denmark, it was verified that fragrances are one of the major causes of allergic contact dermatitis from use of cosmetics.
