An artificial fragrance often contains anywhere from 50 to 300 chemical ingredients. Under IP (Intellectual Property) protection the ingredients are not required to be listed on the product.
More than 1200 of the 3000+ chemicals used in fragrances have been flagged as potential or known "chemicals of concern" by the International Fragrance Association (IFRA).
Diethyl phthalate is another chemical often added to fragrances. Phthalates are plasticizer chemicals which help prolong the life of the fragrance in a product and added to some plastics to make them more flexible.
Phthalates are known to be endocrine-disrupting chemicals which can be detrimental to reproduction, neurology and developmental systems in humans.
When reviewing the ingredients list of a product, all the chemicals used are often not itemised, however, generally hidden under "fragrance".
Try to find products that are fragranced by essential oils or list "natural fragrance" rather than just "fragrance".
