    Study links formaldehyde to more common cancers

  • : Synthetic fragrance, which can be highly irritating and are also a potential source of questionable sub-ingredients such as phthalates; formaldehyde-donor preservatives-such as diazolidinyl urea, DMD hydantoin, imidazolidinyl urea, and sodium hydroxymethylglycinate-which under certain circumstances of formulation and storage, these ingredients have the potential to release formaldehyde in very small amounts; and chemical sunscreens, such as oxybenzone and octyl methoxycinnamate, have safety concerns since many have been shown to have endocrine-disruption activity.
