Parfumurile sintetice sunt nocive -extras wikipedia

Health and environmental issues

Perfume ingredients, regardless of natural or synthetic origins, may all cause health or environmental problems when used or abused in substantial quantities. Although the areas are under active research, much remains to be learned about the effects of fragrance on human health and the environment.

[edit] Health

[edit] Immunological

Evidence in peer-reviewed journals shows that some fragrances can cause asthmatic reactions in some individuals, especially those with severe or atopic asthma.[18] Many fragrance ingredients can also cause headaches, allergic skin reactions[19] or nausea.[20][21][22]
In some cases, an excessive use of perfumes may cause allergic reactions of the skin. For instance, acetophenone, ethyl acetate[citation needed] and acetone[16] while present in many perfumes, are also known or potential respiratory allergens. Nevertheless this may be misleading, since the harm presented by many of these chemicals (either natural or synthetic) is dependent on environmental conditions and their concentrations in a perfume. For instance, linalool, which is listed as an irritant, causes skin irritation when it degrades to peroxides, however the use of antioxidants in perfumes or reduction in concentrations can prevent this. As well, the furanocoumarin present in natural extracts of grapefruit or celery can cause severe allergic reactions and increase sensitivity to ultraviolet radiation.[23]
Some research on natural aromatics have shown that many contain compounds that cause skin irritation.[24] However some studies, such as IFRA's research claim that opoponax is too dangerous to be used in perfumery, still lack scientific consensus.[25] It is also true that sometimes inhalation alone can cause skin irritation.

[edit] Carcinogenicity

There is scientific evidence that nitro-musks such as Musk xylene can cause cancer. However common ingredients, like certain polycyclic synthetic musks, can disrupt the balance of hormones in the human body (endocrine disruption).[26][27] Some natural aromatics, such as oakmoss absolutes, contain allergens and carcinogenic compounds.[24][28]
