Our natural, customized fragrances are a new version of fragrance that is Phthalate-free. This is a plastic-like component that may be linked to reproductive issues in young males especially. Belegenza not only has these specially formulated, but we use a very low concentration of pure fragrance to keep sensitivities from being activated. Some people are allergic to plain foods, (for example, some people are allergic to pure orange oil--therefore just because it is natural and organic, some can still react. To minimize the problems associated with natural and organic fragrances of all types is to use them all in the lowest concentrations possible.
